Using SuPHP on a VPS

  • Hi guys, I am running a site with a WordPress CMS. I tried to install W3 Total Cache to speed up the site files, but I didn’t know which opcode to pick (I am on a VPS), so I put a support ticket in with my host. The host came back telling me the following: 

    APC is not available on your VPS. Your VPS is running PHP with SuPHP, so the APC will not work with it. 

====================================================
-bash-3.1# hostname
server.xxxxx.com
-bash-3.1# /usr/local/cpanel/bin/rebuild_phpconf --current
Available handlers: suphp dso cgi none
DEFAULT PHP: 5
PHP4 SAPI: none
PHP5 SAPI: suphp
SUEXEC: enabled
RUID2: not installed
-bash-3.1#
==================================================== 

The suPHP is a must as it provides an additional layer of protection on servers. It causes php scripts to run under the account username instead of the user ‘nobody’ which is the user that apache/php would run under on a server that is not running suPHP. This feature allows us to more easily track any potential security breaches that come in via insecure php script(s) that a user is running. 

If you still want APC, then we will need to recompile PHP without suphp on your VPS. Please note that some websites scripts may not work with PHP without suphp.

    I also run a forum on the site that is handled with vBulletin. Do I need suPHP? Is the tradeoff for speed with caching worth removing it? I am not a sysadmin but I read that suphp is mostly recommended when on a shared server.

  • If you have your own VPS and can compile apache the way you want (Easy Apache), we have found: PHP 5 Handler-dso, with Apache-Mod Ruid2 is by far the best way to go.
    All the security and convenience of suEXEC, with the blistering speed of W3 Total Cache & APC.

    I don’t recommend suPHP because it’s slow and security it provides is not necessarily better than what you can do by properly configuring your server. Switching to php-fpm or mod_php with APC is where you want to be to start to scale PHP.

    agree with Lesb55, have a chat to the guys at crucial, alternatively if you chat to one of the guys at [link removed] (part of my team) they will be able to assist
