The full name of SELINUX is Security Enhanced Linux (Security hardening Linux), which is a finer-grained setting for the security level of the system. Because the SELinux configuration setting is too strict, it may conflict with the functions required by CM, so we choose to turn it off directly here.

How to temporarily disable SELinux on CentOS 8

Before you start disabling SELinux on CentOS 8, be sure to check the status of SELinux.

To do this, run the following command:

[root@localhost www.linuxidc.com] # sestatusSELinux status: enabledSELinuxfs mount: / sys/fs/selinuxSELinux root directory: / etc/selinuxLoaded policy name: targetedCurrent mode: enforcingMode from config file: enforcingPolicy MLS status: enabledPolicy deny_unknown status: allowedMemory protection checking: actual (secure) Max kernel policy version: 31

This indicates that SELinux is up and running.

To temporarily disable SELinux, run the command.

# setenforce 0

In addition, you can run the command.

# setenforce Permissive

Any of these commands will temporarily disable SELinux until the next restart.

How to permanently disable SELinux on CentOS 8

Now, let's see how to permanently disable SELinux. The configuration file for SElinux is located in / etc/selinux/config. Therefore, we need to make some changes to the file.

# vi / etc/selinux/config

Set the SELinux property to Disabled, as follows:

# 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 three values:# targeted-Targeted processes are protected,# minimum-Modification of targeted policy. Only selected processes are protected.# mls-Multi Level Security protection.SELINUXTYPE=targeted

Save and exit the configuration file, and then restart the CentOS 8 Linux system using any of the following commands.

# reboot# init 0# telinit 0

Now, use the command to check the status of SELinux.

[linuxidc@localhost www.linuxidc.com] $sestatusSELinux status: disabled

SELinux is a critical feature on CentOS 8 that helps restrict unauthorized users from accessing certain services on the system.
