Deploy Rails App with puma

Add puma to you Gemfile:

gem "puma"

Install Puma Gem

change to project directory
bundle install

Start your app via puma

puma -e [environment] -p [port-number] -d

puma -e production -p 9292 -d
This will start the rails app in production environment on port 9292 and daemonize the process

Make sure Apache proxy mods are enabled

sudo a2enmod proxy
sudo a2enmod proxy_http

Setup Apache Config

Example /etc/apache2/sites-available/[app_name] .conf file
<virtualHost *:80>
  ServerName www.site-1.com
  ServerAlias site-1.com
  DocumentRoot /var/www/site-1/public
 
  #<location /assets>
  #  ProxyPass !
  #</location>
  <location /system>
    ProxyPass !
  </location>
 
  ProxyPass / http://127.0.0.1:9292/
  ProxyPassReverse / http://127.0.0.1:9292/ # don't forget the trailing slashes at end!!!
</virtualHost>

Enable site and restart Apache

sudo a2ensite site-1
apachectl -t
sudo /etc/init.d/apache2 restart

To stop the Puma Daemon

// There are better ways to do this, but this is quick and dirty and works for temporary environments

Find Process ID

ps aux | grep puma
lsof -wni tcp:[port_number]

the process you're looking for should be running on the port of your app

Stop Process sudo kill -9 [process ID]

Start Process puma -e [environment] -p [port-number] -d
