正确关闭selinux

、查看当前selinux的状态命令为
  getenforce

、两个都要关。注意先看看有么有这两个文件，如果没有就创建一个，否则后期会出现很多问题

cat > /etc/selinux/config << EOF
# 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 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
EOF

sed -i 's/enforcing/disabled/g' /etc/selinux/config

sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/sysconfig/selinux

、再次查看当前selinux的状态命令为
  getenforce
