How to Temporarily or Permanently Disable SELinux on Linux

Hello colleagues.

Today we will talk about how to disable SELinux. Security is an important part of server management. However, a security policy that is too strict can prevent some tasks from being completed. This is why it is sometimes necessary to disable individual security features.

SELinux is a security control feature that restricts access to certain kernel modules.

SELinux has three modes:

1. Enforcing: Allows access based on SELinux policy rules.
2. Permissive: Registers only those actions that would be denied if they were to run in forced execution mode.
3. Disabled: The policy was not loaded.

By default on Linux, SELinux is enabled and in enforcement mode.

The content of the article:

1. Checking the status of SELinux.
2. Disable SELinux temporarily.
3. Disable SELinux permanently.

STEP 1. Check the status of SELinux.

To view the current SELinux state and SELinux policy, use the command:

$. sudo sestatus

STEP 2. Disable SELinux temporarily.

You can temporarily change the SELinux mode from targeted to permissive with the following command:

$. sudo setenforce 0

However, the change will only be valid for the current session.

STEP 3. Disable SELinux permanently.

To permanently disable SELinux follow these steps:

1. Open /etc/selinux/config file and set SELINUX to disabled mode:

Save the file and restart the server with the command:

$. sudo shutdown -r now

READY.

Thank you all, I hope my article was of some help to you.
