Apache Module — Ruid2

Last modified: August 23, 2024

The mod_ruid2 Apache module is a per-request module that allows a domain’s HTTP requests to run as the owner of that domain. This module is similar to suEXEC and suPHP, but it applies to all HTTP requests.

The EasyApache 4 Default profile installs this module by default with the mod_cgid Apache module.

Requirements

This module does not possess any specific requirements.

Compatibility

The mod_ruid2 Apache module uses a complex security model and may introduce security issues if it is used with some other modules.

When you use this module, EasyApache disables the following Apache modules:

mod_cache
mod_cache_disk
mod_fcgid
mod_lsapi
mod_memcache
mod_mpm_event
mod_mpm_itk
mod_mpm_worker
mod_suphp
mod_userdir

Other considerations

If you use the mod_ruid2 Apache module, you must understand the following caveats:

This module works with all PHP Handlers except the mod_fcgid Apache module. If you enable mod_ruid2 while using mod_fcgid, the system will change your PHP Hander to suPHP. If you enable the mod_ruid2 Apache module, your PHP handler will not change unless you use the FCGId PHP handler.
We recommend that you use this module if you use the CGI or DSO PHP handlers.
For security reasons, the system disables the POSIX PHP extension when you use mod_ruid2.

How to install or uninstall the module

You can install and uninstall the mod_ruid2 Apache module in WHM’s EasyApache 4 interface (WHM » Home » Software » EasyApache 4).
