Centos8关闭SELinux

查看状态

使用sestatus命令查看当前SELinux状态

[root@CentOS8-DEV ~]# 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
Memory protection checking:     actual (secure)
Max kernel policy version:      31

可以得到当前的状态是enabled的

在CentOS 8上永久禁用SELinux

编辑SELinux配置文件/etc/selinux/config

[root@CentOS8-DEV ~]# 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=disabled
# SELINUXTYPE= can take one of these three values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected.
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

将SELINUX=enforcing修改为SELINUX=disabled
重启机器reboot
再次查看当前SELinux状态

?[root@CentOS8-DEV ~]# sestatus
SELinux status:                 disabled
