Here is an example to disable SELinux on CentOS.
Disable SELinux temporary
# setenforce 0
Disable SELinux permanently
From the command line, you can edit the “/etc/sysconfig/selinux” file.
Change to “SELINUX=disabled”
=/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 # SELINUXTYPE= can take one of these two values: # targeted - Targeted processes are protected, # mls - Multi Level Security protection. SELINUXTYPE=targeted
After save the file, you need to restart Linux.
