Deploy Ubuntu 18.04 Bionic Beaver Discussion

I am wondering if there is a variant toturial for the Puma, Nginx and Capistrano setup? Is Puma a less viable app server for production? Can we invoke a small discussion on this?

Hello Chris,
it's the first time I'm trying to deploy an app on a server.
for the moment i have 2 problems.
first, optionnal: I don't have secrets.yml, secrets.yml.example and database.yml.example in my rails app. Do I have to create them and if yes what do I put in my secrets.yml (On the other hand, I have credentials.yml.enc and master.key)
secondly, i'm at the first deploy step and every time i run "cap production deploy" that stop at "git:check" with this message :
git@git.laguil.de: Permission denied (publickey,password).
01 fatal: Could not read from remote repository.
01
01 Please make sure you have the correct access rights
01 and the repository exists.
I had, beforedeploying, generate a pair of key in the sudo user on the server, I had add this public key to the deploy key section of my repo git. I tried to clone the repo on the server but I have the same message. but on local no problem. Do you have an idea of what I did wrong (I look for a solution on google, I try change the git address and several other things since one day). Did I miss something.
And of course thank you very much, Chris, for this article.

Hello,
Thanks for this nice tuto !
I follow instructions but finally I have a problem on cap production deploy.
Seems to upload from git perfectly but problem with bundle install :

*Your bundle only supports platforms ["x86-mingw32"] but your local platforms are
["ruby", "x86_64-linux"], and there's no compatible match between those two
lists.
*
Can you help me ?
Thanks

Soo close to deploying... stuck on capistrano... feeling like giving up on it all.. any help is appreciated.

I am seeing an odd error (at least odd to me, and I have spent a good portion of the day trying to figure this out to no avail:

I run on local: cap production deploy

Deployment starts, but at deploy:migrate, I have an issue:

UPDATE:
Ok. I am ... an idiot unless I have 5-cups of coffee in me and I take breaks after 10+hrs staring at a computer monitor.

I had two setups for the following when I should have only had one. One was directed to: myapp (literal) and myapp (my actual app). And I directed the IP to my actual IP address instead of 127.0.0.1
nano ~/myapp/.rbenv-vars

Thanks a lot for this.
just one thing beyond this,
I added sidekiq, now how can I start it and and hanlde auto restart on die etc things?

I have problem with yarn I do not load the files js of my application I made this change in the environments / production.rb config.assets.js_compressor = Uglifier.new (harmony: true) config.assets.compile = true so that I compiled the app I do not know what else to do me I get this warning back when I'm doing the deploy

Hello Chris
I have this error:
FATAL: password authentication failed for user "deploy"
How is database.yml configured?

I had an interesting thing happen after following this. The instructions were PERFECT because I could not get Nginx or Apache to work with Puma on the production server after from DigitalOcean. So thank you very much for this guide!

Now I have an interesting issue. After successfully going through this guide, I tried running 'rails s' locally and kept getting the error: (erb):18:in fetch': key not found: "DATABASE_USER" (KeyError)

I thought that was strange, because it looks like it's trying to use my production database values rather than the development. I did confirm in my puma.rb file that it's set for the development environment.

I tried commenting out my DB username and pw fields as shown below but I was still getting the same error.

Here's my database.yml file:

# SQLite version 3.x
#   gem install sqlite3
#
#   Ensure the SQLite 3 gem is defined in your Gemfile
#   gem 'sqlite3'
#
default: &default
  adapter: postgresql
  pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
  timeout: 5000

development:
  <<: *default
  database: db/development
  username: seth
  password: 

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  <<: *default
  database: db/test

production:
  adapter: postgresql
  pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
  timeout: 5000
  #username: <%= ENV.fetch("DATABASE_USER") %>
  #password: <%= ENV.fetch("DATABASE_PW") %>
  database: consumer_law

For now I've just deleted the username and password lines from the file and I'm able to successfully run 'rails s' and get Puma working locally again. It does explicitly show in the startup output that it's set to use the development environment settings.

Any ideas why it's trying to use my production username and password fields in development?

Hello Chris,

    passenger-config restart-app /home/deploy/testbootstrap --ignore-app-not-running
   There are no Phusion Passenger-served applications running whose paths begin with '/home/deploy/testbootstrap'.`

I keep getting this error when I deploy and my site is not accessible through my IP address. It pops up a 404 NOT FOUND.

First of all, thank you for the guide.

Question to you about Passenger setup. I'm running Ubuntu 18.04 and did everything like this guide said, but i keep getting an error that *** ERROR: Phusion Passenger doesn't seem to be running. If you are sure that it

Error occurs when cap is running a command to restart Phusion Passenger.

Anyone else ran into this issue?

Update Sorry, my fault - for some reason, i commented out a line in passenger conf file where you add rbenv line, and that was messing it up for me. Anyways, thank you again for the guide :)

hello cris good day, I tell you my problem, I'm following all the steps to do the question until step 4 all right but at the time of deploy I jump an error

NameError: uninitialized constant Dotenv

https://gist.github.com/JoseCed/664ad2516d034605cb8d31705a2795c2

I need help, please

Here are some links and tips I found helpful while setting up the production server. Feel free to add to this by commenting below or suggest any edits:

• Refer to this link to understand how to set up a Rails server on 18.04: https://gorails.com/deploy/ubuntu/18.04
• Refer to this link if you get a packet_write wait or broken_pipe error: https://www.digitalocean.com/community/questions/why-am-i-getting-packet_write_wait-connection-to-xxx-xx-xx-xxx-port-22-broken-pipe?answer=41458 This error usually comes up when you are installing Ruby on the production server and the client thinks the server is inactive.
• Make sure database.yml, secrets.yml, application.yml files are created manually on the server (in the shared folder)
• Edit nginx /etc/nginx/sites-enabled/app-name file and make sure it points to the correct directory. Refer to this link: https://www.digitalocean.com/community/tutorials/how-to-move-an-nginx-web-root-to-a-new-location-on-ubuntu-18-04
• Make sure MySQL privileges are provided to the deploy user

• If you are using GitLab, you'll need to generate SSH public and secret keys on the server and then add the public key to the GitLab user settings.
  The steps to do that are as follows:

  • su deploy
  • ssh-keygen -t rsa -b 2048
  • Press ENTER thrice
  • cat /home/<user-name>/.ssh/id_rsa.pub to obtain the SSH key
  • Navigate to: https://gitlab.com/profile/keys and paste your key there
  • You should be able to use Capistrano with GitLab now (as long as you have followed all the other instructions in the main article and setup deploy.rb correctly)

• Make sure production secret key is set (this can be generated locally using rails secret) and then added to the secrets.yml file in the production server

when i deploy my rails app to VPS then always appear
[deploy:migrate] Runrake db:migrate
00:37 deploy:migrating
01 $HOME/.rbenv/bin/rbenv exec bundle exec rake db:migrate
01 config.eager_load is set to nil. Please update your config/environments/*.rb files accordingly:
01
01 * development - set it to false
01 * test - set it to false (unless you use a tool that preloads your test environment)
01 * production - set it to true
01

but the config/environments/*.rb already set same to above

Thank you very much I have the online project, now I have a question if I create a migration when you run cap production deploy will the migration in production run?

and on the other hand someone could help me on how to run a seed.rb in production.

regards

I keep getting the following error when I am making changes:

Everything will deploy fine and the app will work well but when I create datamigrations, this error pops up. I'm using MySQL on both development and production. I can't find anything on Stackoverflow/Google Searches that has helped so I'm hoping someone here has experience in this matter.

Have you checked the table to see if the 'environment' key has been set? This is a fail-safe for Rails apps to make sure that you aren't wiping out a production database by accident.

I had some problems to make it works, but after some trys, I did :)
(I'm so proud rs)
So, I create many Droplet on Digitalocean to do got this, and in my last try I installed the rails using gem install rails and every thing works fine.

Hello I followed this tutorial carefully purpose when I launch nginx, I have this error message....

sudo service nginx start

    Job for nginx.service failed because the control process exited with error code.
    See "systemctl status nginx.service" and "journalctl -xe" for details.

@leopauld The service is probably already running. Did you try running the systemctl status nginx to see if it's already running and what the output is?

Hello,
I have a problem to deploy, I configured rbenv-vars correctly with my database and my secret key but when I launch cap production deploy, the execution doesn't work...

Hmmm tried this from a fresh rails 6 app.

cap production deploy is failing with

/home/userme/.rbenv/versions/2.6.3/lib/ruby/gems/2.6.0/gems/sshkit-1.20.0/lib/sshkit/runners/parallel.rb:15:in `rescue in block (2 levels) in execute': Exception while executing as userme@123.456.789.10: rake exit status: 1 (SSHKit::Runner::ExecuteError) 
$HOME/.rbenv/bin/rbenv exec bundle exec rake assets:precompile
Compiling…
Compilation failed:
error Command "webpack" not found.

Webpacker docs is saying Make sure you have public/packs and node_modules in :linked_dirs for capistrano deployments. Then If you have node_modules added to :linked_dirs you'll need to run yarn install before deploy:assets:precompile and they have a snippet to add to your deploy.rb...

before "deploy:assets:precompile", "deploy:yarn_install"

namespace :deploy do
  desc "Run rake yarn install"
  task :yarn_install do
    on roles(:web) do
      within release_path do
        execute("cd #{release_path} && yarn install --silent --no-progress --no-audit --no-optional")
      end
    end
  end
end

Testing this now to see if it works... 10 mins later... nope... still busted... will try again later :/

I believe I may need to add capistrano-npm to my Gemfile so npm install can be run in the capistrano deploy scripts.

Do you have any tutorials to setup replicas for the database and load balancers?

Hello. Thanks for this valuable tutorial. I'm at the last stage. I'm just getting a error message.

ERROR MESSAGE:
The application encountered the following error: ActiveSupport::MessageEncryptor::InvalidMessage (ActiveSupport::MessageEncryptor::InvalidMessage)

I have used for recent installation with ubuntu 20.04 and ruby 2.6.6

at some point nginx get unresolved dependencies, and you have to get a new repo:

deb https://oss-binaries.phusionpassenger.com/apt/passenger focal main

in the end the problem is phusion passenger doesn't start automatically. How can I fix that?

Hey Chris. Thank you so much for this guide, it always works. I have just one question, how would I access Rails console in my droplet? Using "rails c -e p" or "rails c" doesn't seem to work.

I'd suggest running mina it is way faster than capistrano! look it up using 'mina gem'

I am getting an error with this method when deploy via capistrano: 01 bash: /home/deploy/.rbenv/bin/rbenv: No such file or directory. Any ideas on how to fix?

Please help! I've successfully completed this tutorial and now have a fully functional DB up and running online.

Now I've just updated my rails app for the first time on my local machine and pushed these updates to my git repo, yet I'm not seeing these updates in production.

How do I update my production application?

Thanks in advance for your time and consideration!

Having trouble getting past the following error on 'cap production deploy'... please help!

Hi guys, how is it going? I'm facing a problem after deploy following this tutorial. After I hit the domain URL into the browser, I see the message "This site can’t be reached mydomain.com refused to connect.". I already deployed this code many times in different VPSs just fine. In this new one, I don't know what's happening. I already tail the logs and I got no clues there. Can you guys help me with some insights?

Also I'm facing this problem with letsencrypt:

~/letsencrypt$ ./letsencrypt-auto
Requesting to rerun ./letsencrypt-auto with root privileges...
[sudo] password for deploy:
Skipping bootstrap because certbot-auto is deprecated on this system.
./letsencrypt-auto has insecure permissions!
To learn how to fix them, visit https://community.letsencrypt.org/t/certbot-auto-deployment-best-practices/91979/
Your system is not supported by certbot-auto anymore.
Certbot cannot be installed.
Please visit https://certbot.eff.org/ to check for other alternatives.

I tried to install on Ubuntu 20.04 and I had no luck. any thoughts?

(this comment would belong to this post https://gorails.com/guides/free-ssl-with-rails-and-nginx-using-let-s-encrypt)

Hi guys, i have some problems with the "SECRET_KEY_BASE" in 'cap production deploy' any idea what i'm doing wrong, by the way thank you for the help!

Even I am newbie... can you elaborate what do you mean by "shared folder", and create the master.key file and then add it to the list of files to symlink every deploy.. 2ndly I want to know, is it not possible to deploy simply copying our project folder to ec2 instance and run rails env=production? instead so many steps.... Sorry in advance, if it is a baseless question... Can you please clarify about secretkey, masterkey and credentials.. which one to use...

Glad I saw this post. Thank you for sharing this. I’ve been searching a lot lately. While I was searching I found this https://stickmanhook.io

Nice post! Thank you

Nice post! Thank you for your video! I have decided my problem while read it. I think you should create tiktok profile and post your video on tiktok. If you want you can get some followers from here Https://soclikes.com

The tutorial was well written though I had some issues along the way and some comments. Main comment is the tutorial should mention somewhere about setting up ufw firewall, or at least linking to Digital Ocean's tutorial on how to do it. My second issue is the method of placing the NGINX server directives in the sites-enabled directory makes it a hassle when trying to follow Digital Ocean's Certbot tutorial. The server directives should be placed in sites-available then symlinked to sites-enabled. Doing it by this method lets you simply install the Certbot app and have it manage your SSL for you as explained in DO's tutorial. The GoRails tutorial on how to install Lets Encrypt is outdated and parts of the suggestions fail so if someone follows this tutorial, they will experience issues either way when trying to add a custom domain and securing it. Another issue is the point about how to not use environment variables should also be edited. secrets.yml doesn't even ship with new rails apps and if you choose to symlink the files, there are some other edits you need to make rather than just uncommenting that line. Ideally the tutorial could account for those edits and reference the correct files to symlink. Last comment, but as far as I saw there was nowhere mentioning configuring your GitHub SSH keys on the new server so Capistrano can read from your repository. The two methods available for this are either adding a new SSH key to your server and placing it on GitHub or using Capistrano's SSH-forwarding agent. A mention of this would be really helpful in the tutorial. Other than the above issues, the tutorial was great and really appreciated.
