檢視防火牆狀態
[root@localhost ~]# systemctl status firewalld.service #檢視防火牆狀態(執行中) [root@localhost ~]# systemctl stop firewalld.service #關閉防火牆 [root@localhost ~]# systemctl disable firewalld.service #禁止使用防火牆(重啟也是禁止的) 如果是內網無所謂,如果是阿里雲或者其他雲建議不要這樣做,開啟防火牆策略即可 檢查防火牆策略 [root@localhost ~]# firewall-cmd --list-all 將需要永久開放的埠加入防火牆 [root@localhost ~]# sudo firewall-cmd --zone=public --add-port=7001/tcp --permanent 重新載入防火牆 [root@localhost ~]# sudo firewall-cmd --reload # 重新載入完成後,再通過 firewall-cmd --list-all 命令檢視防火牆的規則,埠已經加入進去 其他常用命令 [root@localhost ~]# systemctl restart firewalld #檢查防火牆狀態 [root@localhost ~]# firewall-cmd --state [root@localhost ~]# firewall-cmd --list-all #Disable firewall [root@localhost ~]# systemctl disable firewalld [root@localhost ~]# systemctl stop firewalld [root@localhost ~]# systemctl status firewalld #Enable firewall [root@localhost ~]# systemctl enable firewalld [root@localhost ~]# systemctl start firewalld [root@localhost ~]# systemctl status firewalld
