How to Disable SELinux on Centos

There are two different ways to disable SELinux in the CentOS operating system. One method allows you to disable SELinux through a graphical window, the other requires you to change a value in the SELinux file through a text editor. Either method will take you less than a minute and will require a reboot of your system for the changes to take affect.

Instructions

Graphical

1. Click "System," go to the "Administration" menu and select "Security Level and Firewall." Enter the administrator password when prompted.

2. Click the "SELinux" tab.

3. Click "Disabled" in the SELinux settings and press "OK."

4. Reboot your system.

Text Mode

1. Click "Applications," select "System Tools" and choose "Terminal."

2. Type "su" and press "Enter." Type in the super user password. The password will not show up while typing it. Press "Enter" after you type the password.

3. Type "gedit /etc/sysconfig/selinux" and press "Enter."

4. Change the word "permissive" to "disabled" on the sixth line that begins with "SELINUX=". Click "File" and click "Save" to save your changes.

5. Reboot your system for the changes to take affect.
