This post will show how to disable Security-Enhanced Linux (SELinux) on CentOS 6.5. The steps was very simple, but if we did not disable this feature, you may hit a problem when try to do software installation. SELinux checking for allowed operations after standard Linux discretionary access controls are checked.
1. Check selinux status :
[root@centos6 ~]# sestatus SELinux status: enabled SELinuxfs mount: /selinux Current mode: enforcing Mode from config file: enforcing Policy version: 24 Policy from config file: targeted
2. Disable SELinux on CentOS 6.4 permanently :
[root@centos6 ~]# vi /etc/sysconfig/selinux
Change “SELINUX=enforcing” to “SELINUX=disabled” :
# 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
3. Reboot CentOS 6.5 Operating system :
[root@centos6 ~]# init 6
or
[root@centos6 ~]# reboot
