How to Turn SELinux Off
SELinux (Security Enhanced Linux) provides a mandatory access control mechanism to the Linux kernel. The National Security Agency created it as a way to enforce a security policy that the administration sets over all processes and files, rather than allowing users to control the permissions on files which they own. SELinux is turned on by default in Fedora, Red Hat Enterprise Linux and CentOS. In order to disable SELinux on these operating systems, change the SELinux configuration file.
