red hat enterprise linux 7发布后，发现防火墙也变了，如何关闭防火墙呢，下面是方法
1.查看firewall的状态
[root@sztech7 ~]# systemctl status firewalld
firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled)
Active: inactive (dead) since 五 2014-05-23 13:29:44 CST; 2min 27s ago
Process: 840 ExecStart=/usr/sbin/firewalld --nofork --nopid $FIREWALLD_ARGS (code=exited, status=0/SUCCESS)
Main PID: 840 (code=exited, status=0/SUCCESS)
5月 23 13:26:41 sztech7 systemd[1]: Started firewalld - dynamic firewall daemon.
5月 23 13:29:42 sztech7 systemd[1]: Stopping firewalld - dynamic firewall daemon...
5月 23 13:29:44 sztech7 systemd[1]: Stopped firewalld - dynamic firewall daemon.
5月 23 13:30:23 sztech7 systemd[1]: Stopped firewalld - dynamic firewall daemon.
[root@sztech7 ~]#

 

2.临时停止
[root@sztech7 ~]# systemctl stop firewalld
3.禁用firewall启动，后重启后不会自动启动
[root@sztech7 ~]# systemctl disable firewalld
rm '/etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service'
rm '/etc/systemd/system/basic.target.wants/firewalld.service'
4.确认一下服务禁用
[root@sztech7 ~]# systemctl status firewalld
firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled)
Active: inactive (dead)收起
