Question

Unicorn won't point towards other rails project

The unicorn server seems to be continuing to look at rails_project, despite the fact that I’ve edited it to point towards my own project (wll-rails-project).

I have followed

https://www.digitalocean.com/community/tutorials/how-to-use-the-ruby-on-rails-one-click-application-on-digitalocean

I have changed the unicorn log to point to my custom app

listen "unix:/run/DigitalOceanOneClick/unicorn.sock"
worker_processes 4
user "rails"
working_directory "/home/rails/wll-rails-app"
pid "/run/DigitalOceanOneClick/unicorn.pid"
stderr_path "/var/log/unicorn/unicorn.log"
stdout_path "/var/log/unicorn/unicorn.log"

and executed 

service unicorn restart


but the unicorn log seems to keep referring to the orginal rails_project: 


the unicorn log is:

For me the solution was to bundle install --deployment so the unicorn server is installed in the vendor folder of the new rails project. And then you need to point the paths in the .unicorn.sh file to the correct place. In my case there where to extra folders added to the path. /ruby/2.4.0 was created inside vendor/bundle so in .unicorn.sh change to: export GEM_HOME=“/home/rails/project/vendor/bundle/ruby/2.4.0” and so on for the other paths too.

Hope it helps!

the .unicorn.sh file in wll-rails-app is

#!/bin/bash
# This file is meant to be executed via systemd.
source /usr/local/rvm/scripts/rvm
source /etc/profile.d/rvm.sh
export ruby_ver=$(rvm list default string)

export CONFIGURED=yes
export TIMEOUT=50
export APP_ROOT=/home/rails/wll-rails-app
export RAILS_ENV="production"
export GEM_HOME="/home/rails/wll-rails-app/vendor/bundle"
export GEM_PATH="/home/rails/wll-rails-app/vendor/bundle:/usr/local/rvm/gems/${ruby_ver}:/usr/local/rvm/gems/${ruby_ver}@global"
export PATH="/home/rails/wll-rails-app/vendor/bundle/bin:/usr/local/rvm/gems/${ruby_ver}/bin:${PATH}"

# Execute the unicorn process
