RedHat7 关闭防火墙和SElinux的方法

RedHat 7.x 默认不再用iptables管理防火墙，相关命令如下：

一、关闭防火墙
1. 查看防火墙状态
systemctl status firewalld

2. 实时关闭（重启恢复）
systemctl stop firewalld

3. 查看防火墙服务是否开机启动
systemctl is-enabled firewalld

4. 永久关闭
systemctl disable firewalld


二、关闭SELinux
1. 查看当前SELinux状态
getenforce

2. 实时关闭（重启恢复）
setenforce 0

3. 永久关闭
vim /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=permissive    #修改为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

reboot
