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?

By 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.
