阿里云 CentOS 利用firewall 将80端转发至8080

  CentOS 默认的防火墙不是iptables，而是firewalle.

状态：# systemctl status firewalld

启动：# systemctl start  firewalld
停止：# systemctl stop firewalld

禁用：# systemctl disable firewalld

#显示当前开放端口
# firewall-cmd --zone=public --list-ports

1.允许防火墙伪装ip： firewall-cmd --add-masquerade --permanent

2.将80端口的流量转发至8080： firewall-cmd --add-forward-port=port=80:proto=tcp:toport=8080 --permanent

3.重启生效：firewall-cmd --reload
