I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

The operating environment of this tutorial: linux5.9.8 system, Dell G3 computer.

SELinux (Security-Enhanced Linux) is the implementation of mandatory access control by the National Security Agency (NSA), and it is the most outstanding new security subsystem in the history of Linux. NSA developed an access control system with the help of the Linux community. Under the restriction of this access control system, the process can only access the files needed in his task. SELinux is installed by default on Fedora and Red Hat Enterprise Linux, and is also available as a package that is easy to install on other distributions.

There are two situations when linux shuts down selinux:

1. Temporary shutdown:

Enter the command setenforce 0, but it will be turned on after rebooting the system.

2. Permanently close:

Enter the command vi / etc/selinux/config to open the config file

Change SELINUX=enforcing to SELINUX=disabled

Then save the exit.
