Learn more about installing and configuring mod_ruid2 in DirectAdmin. Our DirectAdmin Support team is here to help you with your questions and concerns.

An Introduction to mod_ruid2 DirectAdmin

Did you know that mod_ruid2 is an Apache module that helps boost performance and security while running PHP scripts on a web server?

An Introduction to mod_ruid2 DirectAdminBy leveraging POSIX, mod_ruid2 optimizes web page loading speed and bolsters site protection. Today, we will explore the benefits of mod_ruid2 and take a look at how to configure it within DirectAdmin.

Advantages of mod_ruid2

According to our experts, mod_ruid2 offers the following benefits over other setups:

  • Reduced Disk I/O:

    Mod_php is preloaded in Apache,. This eliminates the need to load the php binary and mod_php libraries repeatedly. Additionally, this optimization reduces disk I/O, resulting in faster performance.

  • Customized Settings per Domain:

    mod_ruid2 lets us modify settings on a per-domain basis using the php.ini file. This allows administrators to set the PHP environment according to the needs of each website.

  • Compatibility with PHP OpCache:

    The mod_ruid2 setup integrates with PHP OpCache, a caching mechanism that boosts PHP performance.

How to configure mon_ruid2

  1. First, we have to log in to our server via the command line with SSH and run this command:

    # grep php1_mode=mod_php /usr/local/directadmin/custombuild/choices.conf -c

    In case the output is “1,” it means that PHP is running as a mod_php module.

  2. Then, it is time to install the mod_ruid2 module, by running these commands:

    # cd /usr/local/directadmin/custombuild/
    # ./build update
    # ./build set mod_ruid2 yes
    # ./build mod_ruid2
    # ./build rewrite_confs

  3. Now, it is time to verify the ownership and permissions with these commands:

    # cd /usr/local/directadmin/scripts && ./set_permissions.sh user_homes
    # find /home/*/domains/*/public_html -type d -print0 | xargs -0 chmod 755
    # find /home/*/domains/*/public_html -type f -print0 | xargs -0 chmod 644
    # find /home/*/domains/*/public_html -type f -name '*.cgi*' -exec chmod 755 {} +
    # find /home/*/domains/*/public_html -type f -name '*.pl*' -exec chmod 755 {} +
    # find /home/*/domains/*/public_html -type f -name '*.pm*' -exec chmod 755 {} +
    # cd /usr/local/directadmin/data/users && for i in `ls`; do chown -R $i:$i /home/$i/domains/*/public_html; done;

By implementing the mod_ruid2 module within Apache, web hosting administrators can boost performance and security improvements. With reduced disk I/O, domain-specific settings, and compatibility with PHP OpCache, mod_ruid2 improves the overall hosting experience. With the steps above, we can successfully install and configure mod_ruid2, providing our websites with better performance and enhanced security.
