Editor to share with you how to disable SELinux on CentOS 8, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

SELinux is a security function embedded in the Linux kernel, also known as security enhanced Linux,SELinux for mandatory access control can restrict users to some rules and policies, and prevent users from performing unauthorized tasks in the Linux system.

1. Check the status of SELinux

First, let's check the status of SELinux. To do this, simply run the command.

# sestatus

From the output above, we can clearly see that it is enabled by default and is in mandatory mode.

2. Disable SELinux (temporarily).

To temporarily disable SELinux or set the SELinux state from the target state to the allowed state, run the command.

# sudo setenforce 0

Temporarily close SELinux

In addition, you can use the Permissive option instead of 0, as shown below

# sudo setenforce Permissive

3. Permanent outage

The configuration file for SELinux is located in the / etc/selinux/config path. To disable SELinux, open the configuration file and set the SELINUX parameter to disabled. Therefore, open the configuration file

Vim / etc / selinux / config

Set SELINUX to disable, as shown below.

Save and exit the configuration file.

4. Restart the CentOS 8 system

For the changes to take effect, restart the system using the following command.

# restart

# shutdown-r now

# init 6

5. Verify SELinux status

Once the system is successfully rebooted, now check the status of SELinux to make sure it is indeed disabled.

# sestatus

At this point, we have successfully disabled SELinux on the CentOS 8 server.

SELinux provides security for your system and uses policies to restrict users' behavior on the system. In essence, disabling SELinux is not a good idea, however, in some cases it is necessary to disable it. In this article, we have demonstrated how to disable SELinux on a CentOS 8 server.
