To temporarily switch off SELinux (Security-Enhanced Linux) enforcement on a Red Hat or CentOS Linux system, you can use the setenforce command with a value of 0.
For example, to disable SELinux enforcement temporarily, you can use the following command:
setenforce 0
This will disable SELinux enforcement and allow you to perform actions that would normally be restricted by SELinux.
To re-enable SELinux enforcement, use the setenforce command with a value of 1. For example:
setenforce 1
It's important to note that this change is only temporary and will not persist after a reboot. To permanently disable SELinux, you will need to edit the /etc/selinux/config file and set the SELINUX option to disabled.
It's always a good idea to carefully review the documentation and use the appropriate commands to manage SELinux on your system. Disabling SELinux can compromise the security of your system, so it should only be done in specific cases where it is necessary.
