Install Phusion Passenger on cPanel or CentOS
This post explains how to install Phusion Passenger on cPanel or CentOS. Phusion Passenger is an open source web application server. It handles HTTP requests, manages processes and resources, and enables administration, monitoring and problem diagnosis.
We need to install Ruby on Rails to install Phusion Passenger. As you know Ruby on Rails feature provided by cPanel is an outdated one and we can’t install Phusion Passenger using this Ruby version. So install Ruby with RVM to get the latest version of Ruby.
Note: Please make sure that your server has atleast 1.5GB of RAM to install Phusion Passenger
Install Ruby Version Manager (RVM):
Install RVM using the following commands:
gpg2 --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 curl -L get.rvm.io | bash -s stable source /etc/profile.d/rvm.sh rvm requirements
Install Ruby with RVM:
rvm install 2.4.0 rvm use 2.4.0 --default
Check the installation:
[root@server ~]# rvm use 2.4.0 --default Using /usr/local/rvm/gems/ruby-2.4.0 [root@server ~]# ruby -v ruby 2.4.0p0 (2016-12-24 revision 57164) [x86_64-linux] [root@server ~]#
gem install rails
Check the Rails version:
[root@server ~]# rails -v Rails 5.1.3 [root@server ~]#
Install Phusion Passenger
gem install passenger yum install curl-devel sqlite-devel
Also, make sure that Apache 2 development headers is installed on the server.
yum install httpd-devel
If you are running a cPanel server, run the following command to install Apache 2 development headers:
yum install ea-apache24-devel
Run the following command to complete the Passenger installation:
Create Passenger configuration file:
Add the following into it:
LoadModule passenger_module /usr/local/rvm/gems/ruby-2.4.0/gems/passenger-5.1.7/buildout/apache2/mod_passenger.so PassengerRoot /usr/local/rvm/gems/ruby-2.4.0/gems/passenger-5.1.7 PassengerDefaultRuby /usr/local/rvm/wrappers/ruby-2.4.0/ruby
Now open this file:
And add the following line:
service httpd restart
