How do I enable LVE and PHP-Selector in LiteSpeed?

In LiteSpeed admin interface do the following:

1. CloudLinux (Admin Console –> Configuration –> Server –> General): CageFS;
2. Enable SuExec: Server-> General -> PHP SuEXEC -> Yes;
3. LSPHP5 external app runs in SUEXEC non-daemon mode ONLY (Run On Start Up –> Yes or No);
4. In LSPHP5 external app (Admin Console –> Configuration –> Server –> External App –> lsphp5)

Change

command => $SERVER_ROOT/fcgi-bin/lsphp5

To

command => /usr/local/bin/lsphp

See screenshot below:

* In order to use PHP Selector and custom php.ini, lsphp5 needs to be in SuEXEC non-daemon mode.

** Some PHP configurations require more memory for SuEXEC to work properly. If you are getting error 500 after switching suEXEC to non-daemon mode, try to increase Memory Soft Limit and Memory Hard Limit for external App ( Admin Console –> Configuration –> Server –> External App –> lsphp5 ) to at least 650/800M.
