SELinux - Turn off SELinux

Type the following command:

echo 0 >/selinux/enforce

You can also use the setenforce command to effectively disable it, enter:

setenforce Permissive

OR

setenforce 0

The above commands will switch off SELinux enforcement temporarily until the machine is rebooted. If you would like to make it permanently, edit /etc/sysconfig/selinux, enter:

vi /etc/sysconfig/selinux

And set / update it as follows:

/etc/sysconfig/selinux

SELINUX=disabled

Save and close the file. The above will only work in CentOS, Fedora and RedHat Enterprise Linux systems. For all other Linux distros edit your boot loader config file (LILO or GRUB boot loader config file such as /boot/grub/grub.conf). Find the kernel line, append enforcing=0 at the end:

title Red Hat Enterprise Linux Server (2.6.18-194.26.1.el5)
        root (hd0,0)
        kernel /vmlinuz-2.6.18-194.26.1.el5 ro root=LABEL=/ console=tty0 console=ttyS1,19200n8 enforcing=0
        initrd /initrd-2.6.18-194.26.1.el5.img

Finally, reboot the system:

reboot
