Deploy Ubuntu 16.04 Xenial Xerus Discussion

Chris Oliver asked in General
Konrad Makowski ·

This is not working on Xenial Xerus because there is no packages for Ubuntu 16.04 in Phusion Passenger repositores yet.

You can try using the older trusty repository for now while they work up on updating their apt repository:

sudo sh -c 'echo deb trusty main > /etc/apt/sources.list.d/passenger.list'
Konrad Makowski ·

nginx-extras require perlapi-5.20.2, libperl5.20 (>= 5.20.2), passenger (< 5.0.28) wich will not be installed

Jakub Syty ·

Yep, i got the same problem here

You guys can remove that passenger repository and install the version directly from Ubuntu. Should be good enough for now, and then once Phusion updates their repo, you can switch back to it so you can continue to get updates.§ion=all

Konrad Makowski ·

We can't, because nginx from Ubuntus repositories does not have built-in passenger support.

any solution for this issue?

Jakub Syty ·

Unfortunetely no solution so far. I'm waiting too ;/

Unfortunately they haven't released a package for xenial yet. It's on their todo list, but they said by June at the latest. That's a long time from now.

Here's how you can install it manually: https://www.phusionpassenge...

Jakub Syty ·

Thanks, it's working for me now! :)

Do you remember what you did here? Having trouble getting past this.

Jakub Syty ·

Exactly by the instructions in tutorial

After changing database.yml and secrets.yml to examples, whenever I run Rails s for running server. I get error and it complains that it can't find the yml files and server will not get started. What can I do?

Chirs this video is great !!!
would you please publish a similar video with deploy rails on unicorn and nginx with good explain about the config!
thanks )

Edit /etc/nginx/nginx.conf file and uncomment #include /etc/nginx/passenger.conf;
For example, you may see this:
include /etc/nginx/passenger.conf;
after this:
sudo service nginx restart

and final check if passeger work:
sudo /usr/bin/passenger-config validate-install

do you see the message "Restarting nginx nginx" when you type "sudo service nginx restart" ? In my case I don't see it and Chris said that something gonna be wrong if you don't see it.

ChaosPredictor ·

I see [ OK ]

strange! I am using ubuntu 16.04 and every thing is working correctly but I didn't saw anything like [ok] or "restarting nginx ... [ok]" like Chris does! weird :/

ChaosPredictor ·

I'm on 14.04 but I enter here because your other question:
"Hi Chris, when I do sudo service nginx restart it doesn't show anything,
you say that this might be an error, I did sudo tail
/var/log/nginx/error.log but I can't see any error there! this is the
output :"

Hi Chris, when I do sudo service nginx restart it doesn't show anything, you say that this might be an error, I did sudo tail /var/log/nginx/error.log but I can't see any error there! this is the output :

by the way when I opened /etc/nginx/nginx.conf the first time, I haven't find the lines passenger_ruby and passenger_root

ChaosPredictor ·

Hi, have the same issue can't find solution in any web.
Did you found something?

Dylan Huang ·

Hi! I had that same problem and the solution for me was to comment out this line in my /config/environments/production.rb file:

"config.force_ssl = true"

What was happening was that each time you connected, the rails application forced you to redirect to "https" for SSL but your SSL cert is not setup yet!

Chris, Thanks so much for this tutorial. I followed along and was able to get this all working on a VirtualBox setup. However a problem i encountered was a bundler error. i had to SSH into the server and use 'which bundler' and add that path into the :default_env in deploy.rb
set :default_env, { path: "/home/deploy/.rbenv/shims:~/.rbenv/bin:$PATH" }

My question after this...Is there an easy way to run custom rake tasks, once deployed?


Ian Hoffman ·

After following this tutorial, I'm still getting the default "Welcome to nginx" page

Raman Bedi ·

You'll need to restart nginx again to get the site up and running.

will_in_wi ·

The Capistrano part of this tutorial is quite out of date. See

I'd be happy to help rewrite that part if needed.

Thanks for this very helpful tutorial, everything works as expected, except for my assets... some of my images aren't showing up in the browser, but they get deployed... I´m not sure what to do... I've been googling around and don´t seem to find a solution

Make sure you're using these helpers for your static assets:

Daði Hall ·

Thanks it worked :)

great tutorial btw!!

Vostok Obuv ·

After installing NGinx it is necessary to set up and activate the firewall - otherwise you won't see even the Nginx start page. See

Vostok Obuv ·

When I use rbenv and launch "cap production deploy" I get an error: "LoadError: cannot load such file -- capistrano/rbenv". On the local computer I use RVM and I want to set up rbenv on the remote one. Perhaps it is not possible? Do I have to have rbenv on the local computer installed?

Cristian Georgescu ·

Newbie question here. I followed the tutorial and I have the rails 5 app on server.
I bundle install everything but when trying to start rails (rails s -e production) I get the rails new prompt I need to create a new rails app. Any tips on how to start it or what I might be missing ?

You don't need to run Rails, Passenger will start the app for you automatically, that's why we set it up this way so you don't have to manage running scripts. It's automatic.

I had to Generate RSA SSH Keys to make things work. The command is "ssh-keygen". See

Jorg Dominguez ·

Hi there!

I have a issue here: No Rakefile found (looking for: capfile, Capfile, capfile.rb, Capfile.rb, /usr/lib/ruby/vendor_ruby/Capfile)

What should I do?

rajesh sah ·

You should run it in local

Great tutorial. Everything went well, but when I do cap deploy production, I get the error below. Any ideas? Thank you!

cap aborted!
SSHKit::Runner::ExecuteError: Exception while executing as deploy@redacted: passenger-config exit status: 1
passenger-config stdout: Nothing written
passenger-config stderr: *** ERROR: Phusion Passenger doesn't seem to be running. If you are sure that it
is running, then the causes of this problem could be one of:

1. You customized the instance registry directory using Apache's
PassengerInstanceRegistryDir option, Nginx's
passenger_instance_registry_dir option, or Phusion Passenger Standalone's
--instance-registry-dir command line argument. If so, please set the
environment variable PASSENGER_INSTANCE_REGISTRY_DIR to that directory
and run this command again.
2. The instance directory has been removed by an operating system background
service. Please set a different instance registry directory using Apache's
PassengerInstanceRegistryDir option, Nginx's passenger_instance_registry_dir
option, or Phusion Passenger Standalone's --instance-registry-dir command
line argument.

rajesh sah ·

I had the same issue, I had missed to uncomment "include /etc/nginx/passenger.conf;" and server_name was not proper. after fixing them its working

what is the server_name? ICan have any domain? Thanks

David Jarillo ·

yes I had the same issue, any solutions?

Getting the same issue -- anyone solve?

I had the same issue , anyone knows please

Almost there but when I run `cap production deploy` I get

00:00 rbenv:validate
rbenv: 2.3.1 is not installed or not found in $HOME/deploy/.rbenv/versions/2.3.1


Is cap checking this on my local machine or the server? I have changed the path to just `$HOME/.rbenv` and still get the same issue.

Also getting an error `There are no Phusion Passenger-served applications running whose paths begin with '/home/deploy/app_name'`. app_name is replaced with the name of my app.

Seems there is another user getting this problem as well.

Aziz NIANG ·

hey Jay, did you end up solving this issue?

Thanks Chris for this video! How do we setup password authentication, if we're using this tutorial to deploy a staging version of the site? I've setup everything via this site and yet it's not asking for passwords upon entering the site.

Hmmm, double check that you restarted nginx and that went correctly. If so, it should pick that up.

Maybe I missed it in the tutorial, but I had to authenticate the DigitalOcean server with GitHub (by creating a SSH key from the server). Capistrano deployment failed until I did that, as the server was denied access to the Git repository.

I get a 'Permission denied (publickey) fatal: could not read from remote repo' when I 'cap production deploy'. The same keys are on DigitalOcean and Github. Pushes to github works fine. I can ssh into the digitalocean server as root or deploy users fine too. Anyone know what I've missed?

I'm getting the same prob. Did you find a fix?
Fixed by running 'ssh-add' on local machine.

Hi Chris,
How I can set domain name to my server ip address to input my site domain instead of writing ip address?


Gustavo Pergola ·

Make sure you added yout domain name in /etc/nginx/sites-enabled/default.
After that, for digital ocean, follow these steps:

Hope it helps ;)

Edit: Don't forget to set up DO namespaces at your domain registrar panel. (tutorial link:

Just to confirm, firstly the domain need to buy in godaddy or some similar, correct? I don't think you can do this with Digital Ocean

Gustavo Pergola ·

Yes, correct. You should look for any domain registrar. Some are:
Network Solutions
A Small Orange
Google Domains beta

Hello Chris

I fixed the issue I initally posted about lol. But now when I visit the URL there's no site to visit, it says unable to connect

Great tutorial say I'm trying to deploy a rails 5 app with ubuntu 16.04 etc... On cap production deploy I get the following error on deploy:migrate

Do you have any pointers? to make it work can't seem to find similar issue on deployment server

note i tried this it didn't work:


Gustavo Pergola ·

Hi Aziz, could you fix it? I'm running into the same problem =/

Aziz NIANG ·

Hey! No not yet, does your passenger:restart say there is no "Passenger served application"?

Gustavo Pergola ·

I solved the issue by configuring my postgreSQL to accept TCP/IP connections from my server. Check /etc/postgresql/9.5/main for postgresql.conf and pg_hba.conf for configurantions about this.

Aziz NIANG ·

Thanks for the tip! I must have a different problem because it's still bugging will figure sth out +1

Erendira ·

Thanks for the tutorial Chris!!

I'm just having an issue when trying to set the branch for the repo, it always took master and I'm using the set branch but nothing happens

Hey @disqus_FdxDeiCXJb:disqus! I'm not sure how you've got it setup, but if you set the branch in your Capistrano config, that should do the trick. You can either do it in config/deploy.rb globally (it defaults to master) or inside each of the stages like config/deploy/production.rb. It's usually just set :branch, "mybranch"

All the other config options are listed here:

Erendira ·

That's the way I'm doing it, in the config/deploy.rb but when I run cap production deploy, it gets the HEAD last commit on master


# ask :branch, proc { `git rev-parse --abbrev-ref HEAD`.chomp } -- try this and ask for the branch, I typed develop, but neither worked
set :branch, 'develop'

0:02 git:check
01 git ls-remote HEAD
01 a64ca2f22cfaeee296f994b1475d422b179ec94a -- this is the only commit on master branch
✔ 01 ubuntu@ 1.825s

Yep your code looks right. I think that git ls-remote is fine because Capistrano actually clones your full repo to the server (all the branches) and then when it does a "git archive branch | tar" command later to make the new release folder, it will grab the branch there. I don't think this step is gonna be the problem, so it might actually be using the right branch.

Erendira ·

Gosh!! found the problem, the app was in a folder inside the main dir, and that causes it couldn't find the gemfile and that's why I was assuming that set branch didn't work.

Now I have another problem :( when it tries to precompile the assets it gives me an error, because mi app is a rails 5 api, how can I disable the assets:precompile?

Awesome! :)

I believe for that, you can either override the deploy:assets:precompile task with an empty task, or you can also possibly remove the web role from the server line in config/deploy/production.rb. That may also disable some other things that run on the web role, but I don't remember what those might be so it might be the best solution for an api-only app.

Erendira ·

# config/deploy.rb

Did the trick, thanks so much for the help :)


you can create the database.yml same way as you did with secrets.yml. Create an empty file in same place where secrets.yml are and then copy the code from your local copy (ie development env). You have to set the credentials accordning to the ones you have set on production obviously :-)

To create the files (assuming you are connected on server) cd into your shared/config/ folder and then type touch database.yml and touch secrets.yml

i have the following error in the tutorial:

what to do?


I'm planning to do a fresh OS installation on my local machine, so I have a question: is there a way to backup my existing ssh keys that I use to login to the server or my repos, or do I have to generate and add a new key in this case? if thats the case I guess all I need to do is to generate the new key on my fresh install and ssh-copy-id to the server again??

Meant to reply sooner, but all your ssh keys are located in ~/.ssh so you can backup that folder and just replace it on your new install to use the same keys.

After getting through the process, when I tried to deploy my project, I kept getting: "Your Ruby version is 2.3.1, but your Gemfile specified 2.4.1"

Logged into the server as deploy, ruby version was 2.4.1. After a lot of troubleshooting, I su'd into root, and found that root had ruby 2.3.1 as it's version.

I figured i must have screwed something up, so I started fresh.... this time watching the output of each command closely.

It seems that the Passenger install (as deploy user) imported ruby 2.3.1... 2.4.1 was already set up under deploy... and this 2.3.1 did not seem to change anything for deploy. However, root, which had no ruby prior to passenger, was now set to 2.3.1.

I've updated root's ruby to be 2.4.1 using the rbenv method as root so that I could get something deployed to practice on... but...

I'm confused as to how and why 2.3.1 got there, and why it's interfering with the deploy command when i try to push an update...

Chris this tutorial is very helpful.
Can i deploy Worpress and Rails both in a server. Like - WordPress for blogging - ( http://blog.URL ) and rails application is deployed to - (http://URL).
Please help me.

Error 403

The passenger_ruby and passenger_root are configured conrrectly. :/

[EDIT] Seem that my passenger is not running correctly. Can anybody help me?

Have you ever find what is the cause of the 403?

Unfortunately, no. I'm using puma now.


Incredibly useful tutorial! For a small bit of extra config and command line hacking, I get to deploy my app to a server I control rather than an option like Heroku. Thanks for putting this together!

I ran into an issue installing this on nginx using rbenv. If you try to cap production deploy and get an error with passenger. Try opening /etc/nginx/passenger.conf and add this to the file.

passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;

to get your specific passenger root type

passenger-config --root

Lovely tutorial... how do you launch the rails console to make a few changes to the application...?

Matt Seeberger ·

Thank you for this guide! One question I have is how do I load the ruby app if I am not able to use git? When I run cap production deploy it fails trying to read from remote repository because it is calling git and I am not using git. I am new to all of this so sorry for my ignorance.

Hi Chris, thanks for brilliant tutorial. I followed it about an year ago and every thing worked smoothly. Until Today I saw that the production.log on the server side isn't updating. It seems to be stuck in 23/5 2017 :) and havn't updated since. So I was thinking, Is there maybe something in the production.rb setup or the sim-links that I could alter to get the production.log updated again? please see my question here about this problem:

Any plan on updating this for a webpacker setup? ruby 2.4.2, rails 5.1.4?

Thanks for this great tutorial and My cap deploy went fine without any error and I removed the default nginx page. After I restarted the nginx again I can't see my rails app running. I got This Site can't be reached. Can you help me on this please?

I got Connection refused is the error.

David Overman ·

404 Not Found

Hi Chris! I have managed to make it work. But give this setup, how could I make rails db:migrate:reset and rails db:seed to restore a backup?
Hey Juan, I would probably just SSH in and run those commands on the server in the app's current directory. You probably could run Capistrano tasks to do that, but SSH is probably easier.
That was the first approach I tried but using 'deploy' user I don't have enough privileges, and if I switch to 'postgres' user I can't run bundle exec. How do you do that? Thanks

I have use Vue.js and user *vue, the single file component.
so, how to deploy it?
Anyone know?
