Linux安装好之后，通常SELinux都是处于默认的开启状态，开启的情况下可能会导致一些服务安装失败。所以，在不需要的情况下完全可以关闭掉。 1.查看SELinux的状态 [root@localhost ~]#
sestatus SELinux status:                 enabled SELinuxfs mount:                /sys/fs/selinux SELinux root directory:         /etc/selinux Loaded policy name:             targeted Current mode:                   enforcing Mode from config file:          enforcing Policy MLS status:              enabled Policy deny_unknown status:     allowed Max kernel policy version:      28

2.永久关闭SELinux 修改配置文件/etc/selinux/config，将其中的SELINUX=enforcing改为SELINUX=disabled [root@localhost ~]#
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=enforcing
SELINUX=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=targeted

3.重启系统，再执行sestatus查看状态 reboot

[root@localhost ~]#
sestatus SELinux status:                 disabled
