How to disable or turn off Security Enhanced Linux (SElinux)

SELinux is a collection of extra security implementations/restrictions on top of the normal Linux security tools. It gives the systems administrator a deeper control than what the kernel typically provides.

Sometimes SElinux get in your way. Let me give you an example of that, I have webservices which used Apache and I'd installed it on my linux server. So when I start it, it starts correctly without any issue but it still inaccessible from outside world because I forgot to give apache user rights to open the ports. You can disable SElinux but you must be sure of what you are doing and what threats are then on the way if you disable it.

You can disable it in /etc/selinux/config file and modify it as follows

SELINUX=disabled

I hope this article helps you to understand about how to disable SElinux feature.
