启动防火墙：systemctl start firewalld.service  
关闭防火墙：systemctl stop firewalld.service  
重启防火墙：systemctl restart firewalld.service  
显示防火墙的状态：systemctl status firewalld.service  
在开机时启用防火墙：systemctl enable firewalld.service  
在开机时禁用防火墙：systemctl disable firewalld.service  
查看防火墙是否开机启动：systemctl is-enabled firewalld.service  
查看已启动的服务列表：systemctl list-unit-files|grep enabled

其它服务的命令同理~

$ 查看RHEL版本

$ 查看防火墙状态，注意到 “Active: inactive (dead)”，所以防火墙是关闭的

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