對防火牆的操作是linux系統很常用的命令。
- 檢視防火牆狀態
systemctl status firewalld
[root@s201 river]# systemctl status firewalld [0m firewalld.service - firewalld - dynamic firewall daemon Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled) Active: active (running) since Mon 2018-12-17 21:51:19 CST; 10s ago Docs: man:firewalld(1) Main PID: 70576 (firewalld) Tasks: 2 CGroup: /system.slice/firewalld.service 70576 /usr/bin/python -Es /usr/sbin/firewalld --nofork --nopid Dec 17 21:51:19 s201 systemd[1]: Starting firewalld - dynamic firewall daemon...

2. 臨時關閉防火牆命令。重啟電腦後，無效
systemctl stop firewalld
[root@s201 river]# systemctl stop firewalld [root@s201 river]# 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) Dec 17 21:51:19 s201 systemd[1]: Starting firewalld - dynamic firewall daemon...

臨時開啟防火牆命令。重啟電腦後，無效
systemctl start firewalld
[root@s201 river]# systemctl start firewalld [root@s201 river]# systemctl status firewalld [0m firewalld.service - firewalld - dynamic firewall daemon Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled; vendor preset: enabled) Active: active (running) since Mon 2018-12-17 21:56:22 CST; 5s ago Docs: man:firewalld(1) Main PID: 70925 (firewalld) Tasks: 2 CGroup: /system.slice/firewalld.service 70925 /usr/bin/python -Es /usr/sbin/firewalld --nofork --nopid Dec 17 21:56:22 s201 systemd[1]: Starting firewalld - dynamic firewall daemon...

- 永久關閉防火牆命令。重啟後，有效。
systemctl disable firewalld
