Edit /etc/selinux/config (e.g. $sudo vi /etc/selinux/config)
Find the line:
SELINUX=enforcing
a) If you simply want to set selinux to permissive mode - which will still warn you when something would have been denied
change to
SELINUX=permissive
b) If you are sure you want to completely disable selinux
change to
SELINUX=disabled
and save (in vi type [Esc] :wq)
SELinux will be disabled after reboot. To turn selinux off immediately, without rebooting use:
$ sudo setenforce 0
