Question
It is possible to use mod_ruid2 with Litespeed?
Answer
Using mod_ruid2 with Litespeed can cause permissions-related issues. If you are running litespeed, you can verify if you are running mod_ruid2 using the httpd -M command.
[09:55:55 cpanel root@host /]cPs# httpd -M | grep 'ruid'
ruid2_module (shared)
You may want to use suexec instead of mod_ruid2. This can be done via the Apache Modules section of EasyApache 4 in WHM. (WHM >> Software >> EasyApache 4 >> Customize Profile >> Apache Modules)
For more information, the following Litespeed documentation is very useful.
