Disable SELinux in CentOS and RHEL

Security-Enhanced Linux (SELinux) is a security architecture integrated into the 2.6.x kernel using the Linux Security Modules. It is a project of the United States National Security Agency (NSA) and the SELinux community. SELinux integration into Red Hat Enterprise Linux was a joint effort between the NSA and Red Hat.

Most of the application needs SELinux to be turned off. Turning off selinux is simple. You can use the following steps to turn off selinux in RHEL or CentOS 6 and 7 operating systems.

Open the file /etc/sysconfig/selinux . The contents will be similar as below.

# 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 - SELinux is fully disabled.
SELINUX=disabled
# SELINUXTYPE= type of policy in use. Possible values are:
# targeted - Only targeted network daemons are protected.
# strict - Full SELinux protection.
SELINUXTYPE=targeted

 

The contents are self explanatory. Change the value of SELINUX as disabled and save the file. Then reboot the system.
