一、关闭防火墙
1. 临时关闭(下次开机,防火墙自启动)
systemctl stop firewalld
2. 查看防火墙状态
systemctl status firewalld
3. 永久关闭防火墙(开机时,不再启动防火墙)
systemctl disable firewalld
二、关闭 selinux
1. 查看 selinux 状态
getenforce
# 输出:Enforcing 启动状态
# 输出:Permissive 关闭状态
2. 临时关闭
# 查看关闭命令参数
setenforce
# 输出:usage: setenforce [ Enforcing | Permissive | 1 | 0 ] 1 表示启动,0 表示关闭
# 临时关闭
setenforce 0
3. 永久关闭 selinux (修改配置文件,即可永久关闭)
[root@localhost ~]# 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=enforcing 修改为"SELINUX=disabled"
# SELINUXTYPE= can take one of three values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
