Linux安裝好之後，通常SELinux都是處於預設的開啟狀態，開啟的情況下可能會導致一些服務安裝失敗。所以，在不需要的情況下完全可以關閉掉。1.檢視SELinux的狀態[[email protected] ~]# sestatusSELinux status:                 enabledSELinuxfs mount:                /sys/fs/selinuxSELinux root directory:         /etc/selinuxLoaded policy name:             targetedCurrent mode:                   enforcingMode from config file:          enforcingPolicy MLS status:              enabledPolicy deny_unknown status:     allowedMax kernel policy version:      282.永久關閉SELinux修改配置檔案/etc/selinux/config，將其中的SELINUX=enforcing改為SELINUX=disabled[

[email protected] ~]# vi /etc/selinux/config# 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=enforcingSELINUX=disabled# SELINUXTYPE= can take one of three two values:#     targeted - Targeted processes are protected,#     minimum - Modification of targeted policy. Only selected processes are protected.#     mls - Multi Level Security protection.SELINUXTYPE=targeted3.重啟系統，再執行sestatus檢視狀態reboot[[email protected] ~]# sestatusSELinux status:                 disabled
