Deploy Ubuntu 16.04 Xenial Xerus Discussion

Chris Oliver asked in General
Konrad Makowski 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'

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.


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

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

Dylan Huang 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?



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


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


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:


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


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 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

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?


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.


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

David Jarillo 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.


Fixed this as per this SO page.


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.


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.
