关闭防火墙(Centos)

注: 搭建服务前须关闭防火墙(否则会导致服务无法访问)

一、firewalld 防火墙

查看 firewalld 防火墙状态:systemctl status firewalld
关闭 firewall 防火墙 systemctl stop firewalld

二、SELinux 防火墙

简介:
SELinux(Security-Enhanced Linux) 是美国国家安全局(NSA)对于强制访问控制的实现,是 Linux历史上最杰出的新安全子系统。

SELinux 分三种模式
Enforcing(强制模式)、Permissive(警告模式)、Disabled(关闭模式)

查看防火墙当前状态:getenforce

#  关闭 SELinux 防火墙

vim /etc/selinux/config		#  编辑 selinux 防火墙的配置文件


# 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	#  需将此处更改为 disabled(默认为 enforcing)
# 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.

更改完后输入命令使其生效 setenforce 0
