如何將SELinux的功能關閉？

有兩種方法, 一種是在開機設定檔 /etc/grub.conf 中, 把selinux=0加到傳遞給kernel的命令列.
ex:
...
title Fedora Core (2.6.x-xxx)
root (hd0,7)
kernel /boot/vmlinuz-2.6.x-xxx ro selinux=0 root=LABEL=/
initrd /boot/initrd-2.6.x-xxx.img
...

或者直接修改SELinux設定檔 /etc/sysconfig/selinux, 把SELINUX這個參數設成disabled, 再重新開機
就可以了.
ex:
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= type of policy in use. Possible values are:
# targeted - Only targeted network daemons are protected.
# strict - Full SELinux protection.
SELINUXTYPE=targeted
