SElinux给各种设置带来的困扰

#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

这表明SELinux已启动并正在运行。

要暂时禁用SELinux，请运行命令。

# setenforce 0

另外，您可以运行命令。

# setenforce Permissive

这些命令中的任何一个都将暂时禁用SELinux，直到下次重启为止。

如何在CentOS 8上永久禁用SELinux

# 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
