Security-Enhanced Linux (SELINUX) is a Linux feature that provides the mechanism for supporting access control security policies.But SELINUX can sometimes get in your way. Therefore you need to turn off-disable SELINUX. However before you turn off-disable SELINUX make sure you have a valid reason ,why you are doing it.
How to turn off-disable SELINUX temporarily
Step 1: First of all Check the current status of selinux using below command:
[root@rhel1 ~]# getenforce Enforcing [root@rhel1 ~]#
For another method use below command which results the same:
[root@rhel1 ~]# sestatus SELinux status: enabled SELinuxfs mount: /selinux Current mode: enforcing Mode from config file: enforcing Policy version: 24 Policy from config file: targeted [root@rhel1 ~]#
Step 2: To temporarily turn off-disable SELINUX use below method:
[root@rhel1 ~]# echo 0 > /selinux/enforce
[root@rhel1 ~]# setenforce 0
Rather you can set it to permissive mode. As a result SELINUX will be giving warning messages instead of enforcing it. To do the same use below command:
[root@rhel1 ~]# setenforce Permissive
Above all method described are not persistent across reboot. As a result it will work till next reboot. Furthermore If you want to do it permanently across reboot follow below procedure.
How to turn off-disable SELINUX permanently
To turn it off permanently change value of “SELINUX” parameter to “disabled” in the file “/etc/sysconfig/selinux” as below
save and quit file using “wq!” command and you are almost done just reboot the system finally.
Finally recheck using below commands:
[root@rhel1 ~]# sestatus SELinux status: disabled [root@rhel1 ~]# getenforce Disabled [root@rhel1 ~]#
