In Fedora Core and RedHat Enterprise, edit  etc selinux/config 
just change SELINUX=enforcing to SELINUX=permissive, and you're done. Reboot if you want to prove it.
For the other Linuxes which don't have the  etc selinux/config file, you just need to edit the kernel boot line, usually in /boot/grub/grub.conf if you're using the GRUB boot loader. On the kernel line, add enforcing=0 at the end.
