Ruby/Passenger/Python applications 503 on LiteSpeed

Symptoms

After installing an application with cPanel Application Manager or CloudLinux Ruby or Python Selector, it can be observed LiteSpeed returns a 503 error page.

Description 

LiteSpeed doesn't function automatically with Ruby/Passenger/Python applications. Configuring applications without performing the setup script will result in a 503 error page when accessing the application URL.

Workaround

1. Access the server's command line as the 'root' user via SSH or "Terminal" in WHM.
2. Run the enable_ruby_python_selector.sh script.

   /usr/local/lsws/admin/misc/enable_ruby_python_selector.sh

   Please note that this command is a universal script that scans known ruby and python installations to configure them in LiteSpeed Web Server.
