3. Modify the selinux state through the configuration file “/etc/sysconfig/selinux”, this method needs to restart the machine

  [root@localhost ~]# gedit /etc/sysconfig/selinux
 # 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
