I have been searching the web for quite a while but haven't yet found a definitive answer: Is Selinux now fully compatible with Cpanel ? I know Cpanel's docs say to disable Selinux prior to install and then afterwards it can be enabled. My question is: When I have a Cpanel server with Selinux disabled and I just enable Selinux without any further adjustment will my server continue to operate normally or will chaos break loose ? Does configuration need to be made manually or is Linux and Cpanel already containing the configuration for WHM/Cpanel to work properly with Selinux set to enforce ? If Selinux is either not compatible or requires complex configuration to work with Cpanel, which alternatives do you recommend ? Will Grsec be a good alternative ?
