Setting up Ruby(Rack app)

Note

AUTOM8N includes a GUI installer of additional modules required for passenger project. Please place a Gemfile file in the application root and AUTOM8N can install the requirements specified in this file

1. Enable the Phusion Passenger module

yum --enablerepo=ndeploy install nginx-nDeploy-module-passenger
/opt/nDeploy/scripts/easy_passenger_setup.sh

2. The above step will install rvm and a version of ruby for the modules working. We can install any version of ruby using rvm

root@cpanel1 [~]# type rvm|head -1

rvm is a function

[root@cpanel ~]# rvm list
Warning! PATH is not properly set up, '/usr/local/rvm/gems/ruby-2.3.0/bin' is not at first place,
         usually this is caused by shell initialization files - check them for 'PATH=...' entries,
         it might also help to re-add RVM to your dotfiles: 'rvm get stable --auto-dotfiles',
         to fix temporarily in this shell session run: 'rvm use ruby-2.3.0'.

rvm rubies

  ruby-2.0.0-p648 [ x86_64 ]
  ruby-2.2.4 [ x86_64 ]
=* ruby-2.3.0 [ x86_64 ]

# => - current
# =* - current && default
#  * - default

3. install bundler for all the rubies so users can run bundle install. For example

rvm use ruby-2.0.0-p648
gem install bundler

4. Register the Ruby backend using the command

root@cpanel1 [~]# /opt/nDeploy/scripts/update_backend.py add RUBY ruby-2.1.4 /usr/local/rvm/wrappers/ruby-2.1.4/ruby

5. cPanel users can install more gems to local folders using

bundle install --path vendor/bundle
or
bundle install --deployment
