How to install suPHP Setup on CentOS 6.x

Add RPM Forge repository.

32-bit:
rpm -ivH http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.i686.rpm
64-bit:
rpm -ivH http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm

Disable RPMForge by default (if you leave things like this enabled, it will break your system).

# sed -i ‘s/enabled = 1/enabled = 0/g’ /etc/yum.repos.d/rpmforge.repo
Install mod_suphp via yum:

Install suPHP

# yum install mod_suphp -y –enablerepo=rpmforge

Edit  PHP Handler:

sed -i ‘s/x-httpd-php=php:\/usr\/bin\/php/x-httpd-php=\”php:\/usr\/bin\/php-cgi\”/g’ /etc/suphp.conf

If you do not perform the above (replace “x-httpd-php=php:/usr/bin/php” with “x-httpd-php=”php:/usr/bin/php-cgi””) you will get the similar issues to the following errors:
[error] [client] SecurityException in Application.cpp:511: Unknown Interpreter: php
[error] [client] Premature end of script headers: index.php
