• ea-apache24 installed

Environment

• PHP Selector
• ea-apache24

Cause

ea-apache24-mod_suexec is not installed

Solution

yum install ea-apache24-mod_suexec

If the server has mod_ruid2 installed:

yum remove ea-apache24-mod_ruid2
yum install ea-apache24-mod_suexec

You may need to:

service httpd restart

If you use CageFS + PHP Selector, you should run this command (update/populate the cagefs-skeleton)

cagefsctl --force-update
