Update On: 23 Jul 2021Install and uninstall mod_mpm_itk in apache2

apache2-mpm-itk (just mpm-itk for short) is an MPM (Multi-Processing Module) for the Apache webserver. mod_mpm_itk which will enable you to run any of your vhost under a separate user identifier (UID) and group identifier (GID). Use these simple steps to Install and uninstall mod_mpm_itk in apache2.

The books and arrangement records for one vhost no higher have to be readable for all the other vhosts.
mpm-itk is based on the popular prefork MPM, which expects it’s non-threaded; in short, this suggests you can run a non-thread-aware key (like many PHP branches) without difficulties. On the opposite hand, you lose out to any administration interest you’d get with strings, of course; you’d have to choose for yourself if that’s deserving it or not. You will also take an added performance hit over prefork since there’s an additional fork per application.

MPM ITK installation option is available in the following cpanel vesrion “All builds of cPanel & WHM version 11.52 or later”
