Disable SELinux

There are times when disabling SELinux is required for some webapp to work.

You can modify the SELinux from /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

Modifying the config file will make SELinux to be enabled (default), permissive or disabled upon boot up. To temporarily disable SELinux use setenforce 0 command.
