參考：
1. 首先不能關防火牆
systemctl enable firewalld
systemctl restart firewalld
systemctl status firewalld
2. 永久開放埠訪問
firewall-cmd --permanent --add-port=80/tcp
firewall-cmd --permanent --add-port=443/tcp
firewall-cmd --permanent --add-port=18080/tcp
firewall-cmd --permanent --add-port=10128/tcp
firewall-cmd --permanent --add-port=10129/tcp
firewall-cmd --permanent --add-port=10130/tcp
firewall-cmd --permanent --add-port=10131/tcp
firewall-cmd --permanent --add-port=10080/tcp
firewall-cmd --permanent --add-port=19229/tcp
firewall-cmd --permanent --add-port=19339/tcp
3. 新增埠**
firewall-cmd --permanent --add-forward-port=port=80:proto=tcp:toport=9091
將 本地伺服器 3000 埠的內容 通過 80 埠暴露出來 提供服務
firewall-cmd --permanent --add-forward-port=port=443:proto=tcp:toport=9443
將 本地伺服器 9443 埠的內容 通過 443 埠暴露出來 提供服務
4. 重新reload
firewall-cmd --reload
systemctl status firewalld
firewall-cmd --list-all
[root@erpbackup sbin]# systemctl status firewalld
