RedHat8关闭防火墙和selinux

（一）关闭防火墙

查看当前防火墙情况

[root@sikanolinuxServer ~]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
Active: active (running) since Sun 2020-07-05 18:33:01 CST; 3s ago
Docs: man:firewalld(1)
Main PID: 2893 (firewalld)
Tasks: 2 (limit: 11336)
Memory: 30.0M
CGroup: /system.slice/firewalld.service
└─2893 /usr/libexec/platform-python -s /usr/sbin/firewalld --nofork --nopid

关闭防火墙

[root@sikanolinuxServer ~]# systemctl stop firewalld

再次查看防火墙

[root@sikanolinuxServer ~]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
Active: inactive (dead)
Docs: man:firewalld(1)

（二）关闭SELinux

①临时禁用SELinux

[root@sikanolinuxServer ~]# setenforce 0

②永久禁用SELinux
查看selinux状态

[root@sikanolinuxServer ~]# getenforce
Enforcing

更改配置文件

[root@sikanolinuxServer selinux]# vim /etc/selinux/config

如图将SELINUX的值更改为disabled，保存退出

这时候再次查看还是selinux状态，发现没有改变

[root@sikanolinuxServer selinux]# getenforce
Enforcing

不过没关系，这里我们reboot重启服务,可以看到selinux已经变为disabled

[root@sikanolinuxServer ~]# getenforce
Disabled
