How to Disable SELinux without reboot in CentOS

Did you know that SELinux supports three major states?

It can be in disabled, permissive, or enforcing state.

Furthermore, these states are set via the SELinux variable in the /etc/selinux/config file. Let’s take a close look at these states:

• Enforcing:

  This is the default state. It means that SELinux is active and is enforcing its policy on the system. Furthermore, violations are reported and denied. This is also called host intrusion prevention.
• Permissive:

  This indicates that SELinux is active but does not enforce its policy on the system. Instead, violations against the policy are only reported but remain allowed. This is also called host intrusion detection.
• Disabled:

  Here, the SELinux code disables further support and boots the system further without activating SELinux.

We can use sestatus to check if SELinux is enabled.

Additionally, we can disable SELinuxis with this command:

sed -i 's/enforcing/disabled/g' /etc/selinux/config

Alternatively, we can edit the /etc/sysconfig/selinux and set selinux as disabled.
