搭建测试环境或者搭建特殊环境需要临时/永久关闭关闭selinux
查看方法
[root@master ~]# getenforce >>Enforcing
输出为“Enforcing”则证明selinux正在运行
输出为“Disabled”则证明selinux已经关闭
若输出为“Enforcing” 想临时关闭：
[root@master ~]# setenforce 0若想永久禁用selinux则需要编辑配置文件
[root@master ~]# vim /etc/selinux/config将SELINUX=enforcing改成SELINUX=disabled即可永久关闭
原配置文件：
# 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
# 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
