Deploy Ubuntu 14.04 Trusty Tahr Discussion

The following commands should be slightly modified:
cap install STAGES=production
cap production deploy

I believe it should be the following:
bundle exec cap install STAGES=production
bundle exec cap production deploy

If you run 'cap' directly from the shell, it searches standard linux PATH and says that cap is not installed.
In other words, the binary is in gems folder ( ~/.rbenv/versions/2.1.2/lib/ruby/gems/2.1.0/gems/capistrano-3.1.0/bin/cap ) and should be called with bundle exec.

At least that's what I found out trying to replicate the installation.

Thanks for this guide, it's my first time trying to deploy an app in rails. With a little help from google and stackoverflow I managed to set it all up and finally created a db, but when I visit my site in the browser I get an error page. It says to check my log file in var/log/nginx but when I try to go there it says:
-bash: cd: nginx: Permission denied

Any idea how I can see the error log? and also do I maybe need to do anything else not mentioned in this guide to get the site live?

Hey, small typo thing: if you select to install with 2.0.0-p481

the Capfile section still says:

# set :rbenv_ruby, '2.0.0-p451'
# set :rvm_ruby_version, '2.0.0-p451'

I'm having capistrano failing on this command of deployment [ -f home/deploy/codeblog/repo/HEAD ]

Thanks!

When I run the command (gem 'capistrano', '~> 3.1.0' It returns this error "unknown command capistrano" any ideas why this might be happening?

This is tutorial is awesome, but i got server hacked withing 3 days on digital ocean. Be sure you close ssh with login/password http://lani78.com/2008/08/0...

Awesome tut, thank you very much.

I managed to deploy but I have an error "We're sorry, but something went wrong."

when i type sudo less /var/log/nginx/error.log i get the following.

Hi, thanks for the tut, it seems like a very concise and informative resource.

I seem to have hit an issue though, when running:

cap production deploy

I get an error:

ERROR linked file /home/deploy/my_actual_app_name/shared/config/database.yml does not exist on my.server.ip.address
cap aborted!
SSHKit::Runner::ExecuteError: Exception while executing on host my.server.ip.address: exit

The backtrace is pretty unhelpful but the tasks: TOP suggests the issue is originating (as expected) from config/deploy.rb

Tasks: TOP => deploy:check:linked_files

I am using Figaro for keeping my password out of git but that should have nothing to do with the file being sent to the server right?

would you happen to know what may be going wrong here?

Thanks in advance

Where is the Gem File ? Please give me the exact location of the Gemfile.
"like /home/rails or /etc/nginx etc."
To add the lines :

gem 'capistrano', '~> 3.1.0'
gem 'capistrano-bundler', '~> 1.1.2'
gem 'capistrano-rails', '~> 1.1.1'

# Add this if you're using rbenv

Hello Chris,

Here is the error I see when I try to run the command bundle --binstubs

deploy@sparktransfer:~/AsachTimepass$ bundle --binstubs

/home/deploy/.rbenv/versions/2.1.2/lib/ruby/2.1.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- bundler (LoadError)

I am using passenger_ruby /home/deploy/.rbenv/shims/ruby;

in the nginx.conf file, but it still doesnt work.

Can you help me ?

I have managed to go through and run the complete tutorial, but after running touch APP-NAME/current/tmp/restart.txt I only see an nginx welcome page on the server IP. How can I debug the problem.

These are my config files
config/deploy.rb http://pastebin.com/1SXMDYvS
config/deploy/production.rb http://pastebin.com/ZYGejqJF
/etc/nginx/sites-enabled/default http://pastebin.com/0JNG54KH

I also tried with SERVER-IP instead of WEB-ADDRESS in server-name in /etc/nginx/sites-enabled/default

Where am I go wrong

Thanks for the tutorial.

I want to add a helpful tip incase anyone else's Rails app has SSL enabled and is not working.

If you have enabled SSL/https on your Rails app, you will need to add another step to this process. I went through this tutorial and was getting ERR_CONNECTION_REFUSED in chrome when I tried to get to my site. I am new to this and it took me hours before I realized what the problem was.

If you follow the steps in this article it should fix the issue.
https://www.digitalocean.co...

Soon i would like to write a deployment guide for opensource project https://github.com/sharetri... from non-server guy perspective. And this guide playing a big role, i hope you wouldn't mind that i will reference it via link?

Hi Chris, I've followed this tutorial exactly and I'm getting the following error and can't figure out why. I also have no idea why example.com is there...

Any ideas? Thanks for taking the time to write this up.

Hey, thanks a lot for this tutorial. This is one of the most comprehensive one that I've come across thus far!

I am running into some trouble however. For some reason, the app that is actually up and running on my server is an older version (from like two months ago) of my application, but the "current" version of the app is my desired up-to-date one. (I see this when I review the code in that directory.)

I've specified that the master branch should be deployed, restarted the web and app servers, precompiled assets. But, I still have this older version running.
(I am having the same problem this person had http://stackoverflow.com/qu...

Does anyone have any ideas as to why this may be the case?

this was very useful for me. Thank you very much for the article!

Hi, thanks for this tutorial, I tried to follow every step, I deployed the app with some fails
http://pastebin.com/zgkQXcqE

the vps still showing the nginx welcome message, I can't figure out why!

Thanks for this, quite helpful. I'm having an issue with capistrano.

cap production deploy

results in

cap aborted!
Don't know how to build task 'deploy:updated'

with a bunch of other errors after it. I think I set everything up as shown here though – any ideas how to solve this?

Hey Chris, thanks for providing this walkthrough, it's been mostly a breeze. One thing I'm stuck on however is generating the database. When I run RAILS_ENV=production bundle exec rake db:create in the /home/deploy/myapp/current directory, substituting "myapp" for the actual name of my app or course, the vps tells me ruby 2.1.1 is not installed, so I install it, then it wants me to bundle install, and so I do, and finally I'm stuck with "Gem::Ext::BuildError: ERROR: Failed to build gem native extension." type errors as the gems fail to compile. Where did I go wrong? I'd be happy to supply much more insight into this issue, up to and including access to the vps! thanks in advance.

Hi,
Thanks for the tutorial. I'm having trouble uncommenting the /etc/nginx/nginx.conf file. It says I have read only permission and cannot edit it, even though I followed the previous steps of setting the permissions. How do I fix this? Thanks again.

Hi Chris

When I ran the commend `cap install STAGES=production`, I came across the following issue.

```

cap aborted!

ArgumentError: invalid byte sequence in US-ASCII

(See full trace by running task with --trace)

cap aborted!

NoMethodError: undefined method `deploying?' for #<capistrano::application:0x007fe88153d1c8>

```

I ran this commend on my local machine, not server end.

When I use 'cap install STAGES=production' i get error kernel_require.rb:55:in `require': cannot load such file -- capistrano/cli (LoadError)
Any ideas to fix it?

Good article, I would like to see how a simple setup like this could be provisioned with Chef. Future article maybe?

Great Tutorial,

but I am getting:

cap aborted!

SSHKit::Runner::ExecuteError: Exception while executing on ip_address: Authentication failed for user user@ip_address

/home/user/.rvm/gems/ruby-2.1.2@myapp/gems/net-ssh-2.9.1/lib/net/ssh.rb:219:in `start'

Any ideas how to get authentication working?

Hi chris, what's the difference with PUMA ? best performance ?

Thanks for awesome guide! just a heads up, in Capfile part you didn't change Ruby version. I chose 2.1.2 but in Capfile it's still 2.0.0-p451.

I changed it to 2.1.2 and all works now,

I have setup nginx + passenger on EC2 instance ubuntu 14.04. I successfully get first page "Welcome aboard" but when I try to get some controller's action I get "page not found 404" error.

Configuration in sites_enabled/default is as given below

server {
listen 80 default_server;
listen [::]:80 default_server ipv6only=on;

server_name localhost;
passenger_enabled on;
rails_env production;

location / {

root /home/ubuntu/myapp/public;

}
# redirect server error pages to the static page /50x.html
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}

how can I run rake on server? I tried to do it via ssh by root and deploy. they both give me following error:

ActiveRecord::NoDatabaseError: FATAL: role "deploy" does not exist

should I run rake via Capistrano? if so, how?

It would be awesome if you could also include how to set up a background job processor like Sidekiq or Resque as a service in ubuntu.

I'm having this problem
$ cap production deploy

set :stage, :production

server 'xxx.xx.xxx.xxx', user: 'user_name', roles: %w{web app}

my /etc/nginx/sites-enabled/default is:

}
}

Any advise?

Hi guys, great tutorial. :)
I did it exactly the same way like described here prior to reading it and wrote a blog on how to install rbenv globally for all users. Check it out here: http://toschas.com/rbenv-se... .

{You'll want to open up /etc/nginx/nginx.conf in your favorite editor} where can find nginx.conf

Nice tutorial, very well explained! @excid3:disqus , could I translate to pt-BR (Brazilian portuguese), to help my Brazilian friends? Thanks a lot.

Thanks for the tutorial! I get most of the way through, but when i try running

cap production deploy

I get the 'authentication failed for user deploy@1.1.1.1' message.

I'm able to SSH into my remote server without entering the deploy user's password, so I'm not really sure where else to tweak. My stackoverflow searching hasn't really turned up any easy solutions. I'd appreciate any thoughts that worked for others.

I'm trying to add my ssh key but when I try to log in into the dropplet my password is asked

sh-3.2# ssh-copy-id deploy@162.243.xxx.xxx

/usr/local/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed

/usr/local/bin/ssh-copy-id: WARNING: All keys were skipped because they already exist on the remote system.

sh-3.2# ssh deploy@162.243.xxx.xxx
deploy@162.243.xxx.xxx's password:

What should I do?

Hi Chris, Time to add ruby 2.1.3

good job Chris, any plans to add sidekiq integration to this post?

I get lost at the nginx.conf part. After editing the file and do a restart I get a [fail] message which I suspect ain't a good thing. When I do which ruby I get /home/deploy/.rvm/rubies/ruby-1.9.3-p547/bin/ruby. (yes i am doing 1.9.3)

Should I have both

passenger_ruby /usr/bin/ruby;
and
passenger_ruby /home/deploy/.rvm/rubies/ruby-1.9.3-p547/bin/ruby
in the conf ?

People still use Capistrano? Dokku FTW

Hi, I am proceeding along with the tutorial, after reading it thoroughly. I find it confusing that the user name is 'deploy' when that term overlaps with Capistrano-installed file and folder names. I used 'deployer' (user) to discriminate from 'deploy' (action). I know this is just a nit, but it cost me some time.

I am deploying to a headless server on my LAN, so I skimmed through the Droplet stuff.

When i start cap production deploy, i have errors:

cap aborted!

SSHKit::Runner::ExecuteError: Exception while executing on host 104.131.87.26: ln exit status: 1

ln stdout: Nothing written

ln stderr: Nothing written

After I installed the postgres, I ran the script below
```
sudo su - postgres
createuser --pwprompt

```
However, it showed, "createuser: creation of new role failed: ERROR: role "postgres" already exists"

What's the problem?

Hey,

Very nice tutorial, it worked for me the first time (with hardcoding the secret and database password). One thing I missed was environment variables, as they are also an important part of deployment. I tried to deploy another project using environment variables, but I couldn't get it to work.

I spend hours looking around on how to get environment variables to work. I used rbenv on my server which needs the 'rbenv-env' plugin. I didn't realize after a few hours that I needed this plugin to get my environment variables to work.

It would be nice to see it added to this tutorial. I am sure others have had problems trying to figure out what the right/easiest way is to achieve this.

I ran `ssh-copy-id deploy@IPADDRESS` and I'm able to SSH into the VPS without having to put in a password, however, when I run `$ cap production deploy` I get this error:

[ecc89106] Warning: Permanently added the RSA host key for IP address '192.30.252.129' to the list of known hosts.

DEBUG[ecc89106] Finished in 0.742 seconds with exit status 128 (failed).
cap aborted!
SSHKit::Runner::ExecuteError: Exception while executing on host xxx.xxx.xxx.xx: exit

I only have `authorized_keys` and `known_hosts` within /home/deploy/.ssh/. Do I need to manually copy over my public/private keys as well?

Thanks for the really clear tutorial. I have however had difficulty getting all of the way through to a working deployment. A couple of points that threw me or might need further clarity are as follows (working with rbenv):

1. The createuser --pwprompt should I believe be createuser [user name] --pwprompt

2. When running the cap commands I need to prefix with bundle exec.

3. The Capistrano section is all run locally, not on the server.

This gets me through to the stage where I deploy, however on running the

bundle exec cap production deploy

I get an error as follows:

rbenv: bundle: command not found

cap aborted!

SSHKit::Runner::ExecuteError: Exception while executing on host 109.74.205.192: bundle exit status: 127

I do seem to get past this stage by manually performing sudo apt-get install bundler. However that doesn't seem the right approach to me and when successfully deployed after that I get a passenger error as follows:

Hi Chris!

I followed your tutorial but after deploy and putting the IP of the server to the browser I get a message "We're sorry, but something went wrong." I did asset precompile and db:migrate either. I also tried to run the app with webrick on port 3000 and it went all fine. My nginx log file is empty. What do you suggest?

Thank you.

Hi, I'm getting this error when I run cap production deploy

DEBUG[9cef5778] Could not locate Gemfile
cap aborted!
SSHKit::Runner::ExecuteError: Exception while executing on host my.server.ip.here: bundle exit status: 10

any advice? Thanks!

Very Nice tutorial

but I could not get how to start rails app as no where rails is installed can please get back to me ASAP

Thanks for your tutorial! but I have one problem with ssh key. When I trying to deploy I had error with ssh key. The problem is that if I authenticate to server via root@IpAddress it goes via ssh keys but when I try with deploy user it prompts me the password. Should I write deploy's password somewhere like production.rb or do you have any solution? I am very new at deploying projects so any help may help me. Thanks

Step - Installing Ruby using rvm, there is one more step which needs to be added before rvm could be installed...

gpg --keyserver hkp://keys.gnupg.net --recv-keys D39DC0E3

My migration is not running automatically I have added

require 'capistrano/rails/migrations' -> in Capfile

&

before :starting , 'deploy:migrate' -> config/deploy.rb file still my migration is not running

please Help anyone ASAP

Awesome setup

Is there a tutorial that I'm missing for this? I guess I will try with one of my rails apps but if someone could provide me a link to the tutorial on how to build this app or explain this part about the Gemfile to me that would be great( I know what a Gemfile is, just not in context to the tutorial)

is it the same method on EC2

is it possible to deploy by using git to push the rails up to the server and then use the same nginx with passenger configurations

Hi Chris! Can you help me ?. I get "We're sorry, but something went wrong." then I run "sudo nginx -t" it says syntax is ok and nginx.conf test is successful. What should I do?

The Capistrano section makes a huge assumption that will trip up a newbie (like me).

Up to that point, bundler has not been installed, so there is no Gemfile (beyond the template) and the subsequent 'bundle --binsubs' command will fail.

Don't follow the advice in the shell and install bundler using apt-get, it will reset your Ruby version back to 1.9. Instead, use gem like this:

$ gem install bundler
$ export GEM_HOME=$(ruby -e 'print Gem.user_dir')
$ bundle init

Outputs; "Writing new Gemfile to /home/deploy/Gemfile"

Now you can edit Gemfile and run bundle commands.

WARNING: If you are using rbenv, you have to uncomment this line in your Gemfile:
# gem 'capistrano-rbenv', github: "capistrano/rbenv"

Stuck on, "cap install STAGES=production".
Getting, "WARNING:root:could not open file '/etc/apt/sources.list.d/passenger.list'

The program 'cap' is currently not installed. You can install it by typing:
sudo apt-get install capistrano"

This seems to work:

$ bundle exec cap install STAGES=production

Guess rbenv users all have the rbenv-binstubs plugin installed?

Many thx,It is very very helpful :)

Any suggestions??

Used only a portion of this tutorial; using rbenv to install ruby version 2.1.3; i was having problems installing mechanize gem. The part where you showed how to setup ruby using rbenv benefited me. Excellent tutorial

So how do you got about debugging errors where Capistrano cannot find gems. Even when gems are in the Gemfile and work just find if you run the rails app with 'rails s'

I went through the tutorial. I had a few issues but managed to get through it.
However now that I have finished it. It looks like the rails application is not actually running.
There are no log files in 'myapp'/log (I am not sure where they logs would be).
When I go to the IP address for my server all I see is the welcome to nginx. I am not sure if there is supposed to be another url I go to instead.

Hey Chris, great tutorial! I am stuck at the end here, I've been beating my head against the wall all afternoon trying to get it to work. I am getting this error in my production.log:

ActiveRecord::NoDatabaseError (FATAL: role "deploy" does not exist);

Here is my database.yml:

production:
adapter: postgresql
encoding: unicode
pool: 5
host: ""
database: itt_production
username: postgres
password: ""

My pg_hba.conf has everything in trust mode, so this should work. When I switch the pg_hba.conf over to password or md5, and put a password in the database.yml file, I get an error that no password was provided; even though I've provided one. I noticed someone else had an error like this down in the comments, but there was not a resolution posted. Is this something you are familiar with?

sudo nginx -t

nginx: [emerg] invalid number of arguments in "passenger_ruby" directive in /etc/nginx/nginx.conf:72

nginx: configuration file /etc/nginx/nginx.conf test failed

Result of "which ruby"
passenger_ruby /home/deploy/.rvm/rubies/ruby-2.2.0/bin/ruby

hello, i did everything like in this tutorial, but when i try to access my vserver i just get a "Incomplete response received from application" response in my browser.

Users using the RVM method need to execute this command after 'source ~/.rvm/scripts/rvm' -- 'echo "source ~/.rvm/scripts/rvm" >> ~/.bashrc'; otherwise if you exit the terminal session and log back in it will not be loaded. If you are getting a message that 'rails' isn't an installed gem this is likely the cause I would think.

Can the guide be updated with how to correctly handle the production database.yml and adding the secret_key as an environment variable for for nginx?
It is also a bit unclear about at what point are we cloning the repo to the machine vs what is committed to the repo.

`cap production deploy` returns `ERROR rbenv: 2.0.0-p451 is not installed or not found in ~/.rbenv/versions/2.0.0-p451`. Any ideas?

Excellent tutorial! Any chance you can explain how to set up multiple rails apps on a single droplet?

"The first step is to add Capistrano to your Gemfile"

Here we create a new Rails project and edit it's Gemfile or just create a file called Gemfile anywhere in the system?

What should changed if my project is private and I don't want to put on github?

Hi! I followed all the tutorial and everything is working fine. The only thing I cannot do and I would like to be able to do is to run rails console on the server. When I run 'RAILS_ENV=production bundle exec rails console' in the /current folder it looks like there isn'n a rails project. I'm missing something in the command? How can i get the console working? Thank you

is there a video about it?
Thanks!

Thank you for step by step process. I ended up with 403 forbidden error at the end. Could you shed some light on what might have went wrong. I posted it on stackoverflow as well but nothing is working.
http://stackoverflow.com/qu...

Thanks!

After trying out various articles/tutorials, this tutorial worked great! The setup was flawless!

will I be able to scale the VPS servers horizontally like in heroku?

Great guide. I had a few errors, namely that I needed nodejs installed on the server and that you should get your passenger_ruby path using the passenger-config --ruby-command (at least for RVM).

Hi Chris,

I've tried to follow your steps with true care, but for some reason my Nginx is jinxing me :(
I just can't figure out what to do.. just a starting developer alone in the scary world of deployment. Could you maybe help me for a few minutes, for I am sure you are a true pro.
Capistrano seems to be connected, but presents us with an ssh error; permission denied.
There's also a problem with nginx: sudo service nginx restart presents me with FAIL, I've tried
nginx -t, which presents me with a few errors, though sudo nginx -t says everything is fine.

I'm a little lost..

Thanks and it's no problem if you don't want to,

Abel

Great tutorial, Thanks! I had the same issue as @disqus_sRbyuMSsk1:disqus . I also always forget that I need to create the secrets.yml values in production. It would be great to see a section about adding environment variables in the future.

I have gone through all the process and cap production deploy become successfull, but at visiting my IP address, i am getting message "We're sorry, but something went wrong(500)"
Please suggest me what to do, i have already spend my 3 days to solve it.
Thanks.

The command:

gpg --keyserver keyserver.ubuntu.com --recv-keys 561F9B9CAC40B2F7

I had to change to get around firewall problems
gpg --keyserver keyserver.ubuntu.com:80 --recv-keys 561F9B9CAC40B2F7

Had error when I tried to run my app and got error that it could not compile the app, I was missing:
apt-get install libcurl4-openssl-dev

I found this using the passenger tool passenger-install-nginx-module which should be highlighted as a resource.

I had to change following
gpg --keyserver hkp://keyserver.ubuntu.com --recv-keys 561F9B9CAC40B2F7
to
gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 561F9B9CAC40B2F7

It was getting blocked by firewall.

Getting following error on `cap production deploy`

https://railsbox.io/ - I think it can help

I have just automated the process of setting up a production server for Ruby on Rails production application. It includes Nginx, Redis, Memcached, Ruby with RVM, Unicorn or passenger, Mysql or Postgresql.
It uses Chef, knife solo and librarian. No need to be afraid, they are simple commands for you. Hopefully it can some of you to cut on time they spend for server setup.

Thank you very much gorails.com I succesfully installed rvm on my ubuntu 14.04. This has been a night mare for me, installing rvm correctly.
I couldn't find a good how to guide on this not until i stumbled upon gorails.com. I now bookmark this site and joined the mailing list so i can also share with others not in this group.

I got these errors when running `cap production deploy`:

DEBUG [7923ef33] Finished in 0.010 seconds with exit status 1 (failed).

I put the rails app here:

very thanks for post!!!!!!

Adding Capistrano I get error:

Retrying dependency api due to error (2/4): Bundler::HTTPError Network error while fetching https://bundler.rubygems.or...

using rvm. It helps changing Gemfile to:

group :development, :test do
gem 'capistrano', '~> 3.4', require: false
gem 'capistrano-rvm', '~> 0.1', require: false
gem 'capistrano-rails', '~> 1.1', require: false
gem 'capistrano-bundler', '~> 1.1', require: false
end

and execution:

bundle install --full-index

This tutorial worked, but need some addition, especially for installing nodejs on first step and add environment variables on /etc/nginx/nginx.conf.

BTW, thank you very much for pointing in the right direction.

Please can you help me out, I got this error executing "capistrano production deploy":

Thanks!

So I don't need to have the secrets.yml and database.yml files on my rails project? Just the examples?

Thanks awesome tutorial.

The Java runtime needs to be noted also. I am stuck here in the deploy stage:

Psych::BadAlias: Cannot load `Rails.application.database_configuration`:
Unknown alias: default

Google results in lots of comments about your default section of your database file. I took those right out and hard coded them vs the alias and I still get this error.

Awesome tutorial Chris Oliver very detailed and well explained. I managed to get the server up and running. However, I have one hiccup, after I run cap production deploy some of my assets do not show up. Some images appear, others don't and when viewing the webpage on mobile it seems the css doesn't work as well ( showing the desktop site when view from mobile ). Any idea why this may be so?

The following are two logs that appear in red when cap production deploy is run:

Hello,

Please help urgent, I'm currently using mysql2 as the adapter. When i try run "rails generate scaffold User email", I get the error -

/home/deploy/.rbenv/versions/2.2.3/lib/ruby/gems/2.2.0/gems/railties-4.2.4/lib/rails/application/configuration.rb:110:in `database_configuration': Cannot load `Rails.application.database_configuration`: (RuntimeError)
Could not load database configuration. No such file - ["config/database.yml"]

I have already configured my database.yml as

production:
adapter: mysql2
database: deploy_test
username: deploy
password: password

You mention that Capfile should include `require 'capistrano/rails'`. However the base cap installation has commented out ` # require 'capistrano/rails/assets' # require 'capistrano/rails/migrations' ` What is the delta between these two options?

Thanks for the guide, very useful! I have "thin" gem installed in my gem file. So, the nginx is connect thin or Passenger? Do I need any config for better performance?

HI , i try to deploy by following your tutorial but every time i run i saw this in in server
nginx error file

This has been a great help, but I am totally stuck now. Every time I manually create the database on the server as you suggest, it is created successfully. However, when I try to connect to it with my deploy user, it tells me the database does not exist. But if I login as the postgres user, it is there. What am I doing wrong, and how can I fix it?

Hey Chris,

Anyway I could get a link to download this video, would be helpful for easy reference. Thanks so much!

Best!

Sweet...thanks Chris!:) FYI creating my second droplet on Digital Ocean. Going to see how difficulty it will be to manage my own servers...two reasons 1. Cost (cheaper and faster with SSD) 2. With you instructions, it seems easier to get something up and running and I get more granular control over the environment...been having issues with other hosting services. Security is the one major area of concern going forward. Also, is there a good service or app for monitoring (like when the app goes down)?

this is an incredibly huge pain point for us ... thanks for video (pray you keep updating it)

10+ thx!

This is a fantastic article that I have used to deploy over 5 applications! Thanks so much for iwriting it!!
I find that the postgres createuser command is a bit old and since postgres no longer prompts for options by default.. I find it works better with

createuser --interactive --pwprompt

,

Be great to see a tab for installing ruby using ruby-install and chruby, and an update to the nginx section showing how to set passenger_ruby when using chruby.

ruby-install and chruby makes installing ruby and switching between versions so easy even I could do it!

Hello I am trying to install Fedena School ERP using Nginx and Capistrano. I have managed to get Nginx running but now I am completely confused, I really don't know where to go from here; the entire Capistrano process makes me confused. Also, I already have my app folder locally and not on git.
Please I need help on this please.

Hey! Thanks for detailed guide. However, I'm stuck with a problem while setting up a server using rvm method.

App 25994 stdout:

App 25994 stderr: *** ERROR ***: Cannot execute /home/deploy/.rvm/wrappers/ruby/ruby-2.1.5@gemset_name/ruby: No such file or directory (2)

: Could not spawn process for application /home/deploy/india_boulevard/current: An error occurred while starting up the preloader. It exited before signalling successful startup back to Phusion Passenger.

I tried changing following line, but no luck so far :(

passenger_ruby /home/deploy/.rvm/wrappers/ruby-2.1.2/ruby; 

EDIT: Thanks to Stephen Dolan's comment I solved the problem like this http://stackoverflow.com/a/...

Hello! Any reason you didn't place capistrano related gems into the development group?

In "Installing Nginx" section, why do you have the same apt-key and apt-get commands repeated twice?

I was getting the following error upon deploy:

rbenv: version `2.1.2' is not installed (set by RBENV_VERSION environment variable)

I found this fix, which worked for me:

set :rbenv_path, '/home/deploy/.rbenv/'

The source said to add it to deploy.rb or it wouldn't work. Sure enough, you can't add it to the Capfile like the other rbenv settings. Not sure why. I'm posting in case it helps others, and for the next time I read this article to setup a server :)

I also had these issues:

error (upon cap production deploy): Could not find a JavaScript runtime

fix (on the server command line): sudo apt-get install nodejs
----
Postgres only allowed connections from the postgres system user, so:
sudo su postgres
psql -U postgres -h localhost
(in psql): alter user postgres with password 'yourpasswordhere'

I bought Passenger's enterprise license, It tell me "uninstall it by removing the directory in which you extracted Phusion Passenger". Could you tell me which directory should I remove? Thanks!

Thanks Chris for this informative tutorial. Two questions here. What should I do if I don't want to use github or bitbucket etc? I just want to develop locally and upload to the server using ssh, ftp etc. Another question is that is it possible to deploy multiple Rails apps in a single VPS in the configuration described in your tutorial? Thanks.

Hi i am unable to run my rails application in production mode. I am using AWS EC2 and in development mode it is working fine but in production mode it give me error "Incomplete response received from application" I searched it on google but didn't find any proper solution yet.

Anyone here to help me?

Hello,
Chris for thirst, thx for that great article. It would be
great if you write few words about scalling up application into many
passenger workers. I couldn't find any good and easy to understand
tutorial how to do that on custom vps instance.

does anybody received this error when refreshing server?
Incomplete response received from application

GREAT Tutorial ! I set this up with couple of hours.

Hello @excid3:disqus ! Thanx for tutorial! I faced with problem that I trying to solve at least 4 hours..
When I create user for Postgres it returns me the next error:

createuser: could not connect to database postgres: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

It seems that postgres was installed properly

[sudo] password for deploy:
Reading package lists... Done
Building dependency tree
Reading state information... Done
libpq-dev is already the newest version.
postgresql is already the newest version.
postgresql-contrib is already the newest version.

Command ps auxwww | grep postgres shows the below

deploy 1869 0.0 0.1 13456 956 pts/1 S+ 09:16 0:00 grep --color=auto postgres

How can I fix this problem? I've already tired googling..

There's a section of the article that says: "For the rest of this tutorial, make sure you are logged in as the deploy user on the server!"

However, starting at the section named "Capistrano Setup", you actually supposed to be on your local computer (NOT the the remote server).

With Rails 4.2.2 (rvm) I also needed to install

sudo apt-get install libgmp-dev

in order to install 'pg' gem

Even though I have to admit that I haven't watched the full video, this seems to be a great resource for a lot of people to learn how to deploy your Rails application on a production server – so first of all, big thanks for publishing it and helping a lot of Rails developers!

However, judging from the comments, quite some people seem to have their problems in getting everything to work.

I do not know if this will be considered a shameless plug but since my whole business is about running Rails applications in production, I want to point everyone who has made it through this tutorial to https://efficientrailsdevop... – a book about managing your Rails environment with Ansible. It will be of great value if you are looking for a more controlled and reproducible approach to provisioning and deployment.

Great tutorial ! But :
What if I'd like to deploy a second rails app to my vps ? How should I modify the /etc/nginx/sites-enabled/default file to respond to
mysite.com/app1 and mysite.com/app2 ?

How can I setup email smtp production settings after successfully installing this?

Hi, i'm pretty new to rails and discovered your site with this guide. I followed all the steps until the "cap production deploy" that gave me this error : (cap production deploy --trace) - Im using cloud9 online IDE to follow this guide.

Until the "cap production deploy" all was good. Do you have an idea on what's going on ?
Thanks

Should there have been a step in this tutorial to install Rails on the server? Say around the area where Bundler is installed? Or did you pick an image that had Rails included?

After doing everything right, and destroying almost 10 droplets. I keep getting this error.

We're sorry, but something went wrong.
We've been notified about this issue and we'll take a look at it shortly.

The Phusion Passenger application server encountered an error while starting your web application. Because you are running this web application in staging or production mode, the details of the error have been omitted from this web page for security reasons.

Please read the Passenger log file to find the details of the error.

Alternatively, you can turn on the "friendly error pages" feature (see below), which will make Phusion Passenger show many details about the error right in the browser.

To turn on friendly error pages:

Nginx integration mode

Apache integration mode

Standalone mode

Thank you for this great walkthrough!

I think the two lines for installing nginx are duplicates.

To deploy multiple Rails apps to the same server, you will need to replicate the capistrano settings for the second app, create another database, and change the default file in /etc/nginx/sites-enabled like the following:

server {
listen 80;
listen [::]:80 ipv6only=on;

server_name domain1;
passenger_enabled on;
rails_env production;
root /home/deploy/first_app/current/public;

# redirect server error pages to the static page /50x.html
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}

server {
listen 80 ;
listen [::]:80;

server_name domain2;
passenger_enabled on;
rails_env production;
root /home/deploy/second_app/current/public;
# redirect server error pages to the static page /50x.html
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}

Hope this helps someone. Many thanks Chris for this tutorial.

when i run " cap install STAGES=production " command in my local machine i am getting below error
can you please help me

/home/home/.rvm/rubies/ruby-2.2.3/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require': cannot load such file -- capistrano/cli (LoadError)
from /home/home/.rvm/rubies/ruby-2.2.3/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require'
from /usr/bin/cap:3:in `<main>'

it does't create capfile in my app

when i run " cap install STAGES=production " command in my local machine
i get perfect result

cap install STAGES=production
mkdir -p config/deploy
create config/deploy.rb
create config/deploy/production.rb
mkdir -p lib/capistrano/tasks
create Capfile
Capified

but doesn't create capfile in my application

the passenger ruby lines in nginx.conf are moved to a file called passenger.conf

Man, such a dope walkthrough and Vid. Thank you for this.

@excid3:disqus I've been deploying on Digital Ocean and works so fine! But Now i had to deploy in other cloud... everything goes ok... but, when i access from browser with ip... i got nothing!

passenger-status: "Phusion Passenger is currently not serving any applications."
nginx status: "nginx is running"

On nginx.conf there is that line: include /etc/nginx/passenger.conf;
And inside de passenger.conf i put:

passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;
passenger_ruby /home/deployer/.rbenv/shims/ruby;

in my case, of course... Any ideas?

Hi Chris. I followed your tutorial point to point and implemented 3 times in 2 days. But I don't seem to fix this nginx 403 forbidden error. I changed permissions. I tried many solutions on stack over flow on the same or similar issue. But nothing seems to work. Could anybody please tell me what might be the issue. I ll be attaching my stackflow thread here to follow up. http://stackoverflow.com/qu.... Please help needed.

Hi, great post ... I have already a ruby on rails webapp on Ubuntu 14.04 in my case I want update my Ubuntu Server version -> Ubuntu 16.04 so for that topic exists somewhere a best practice or somebody want share any advices ...? thank you in advance ...

Hey there !
I'm trying to deploy on a private server following this tutorial with a rails 5.2 app and somehow when I cap production destroy, i get an error saying

01 SassC::SyntaxError: Error: File to import not found or unreadable: bootstrap/scss/bootstrap.
01 on line 9:1 of app/assets/stylesheets/application.scss
01 >> @import "bootstrap/scss/bootstrap"; // from the node_modules

Looks like it doesn't bundle or like node_modules aren't there ?
From the server machine when i try to bundle or yarn from there, everything seems to be installed already.. where are supposed to be the node_modules on a capistrano deploy ?
