How to Disable SELinux on CentOS

Before we start, make sure that SELinux is disabled. Run

system-config-securitylevel

or edit /etc/selinux/config

# This file controls the state of SELinux on the system.
 # SELINUX= can take one of these three values:
 # enforcing - SELinux security policy is enforced.
 # permissive - SELinux prints warnings instead of enforcing.
 # disabled - No SELinux policy is loaded.
 SELINUX=disabled
 # SELINUXTYPE= can take one of these two values:
 # targeted - Targeted processes are protected,
 # mls - Multi Level Security protection.
 SELINUXTYPE=targeted
 to disable SELinux, and ...

and type:

echo 0 > /selinux/enforce

… for the change to take effect. Happy trying!
