Centos 设置iptables端口转发 “Unit iptables.service could not be found”错误

将端口80映射到8080

• Centos6

iptables -t net -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-ports 8080

service iptables save

service iptables restart

• Centos7

yum install iptables-services

systemctl enable iptables

iptables -t net -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-ports 8080

service iptables save

systemctl restart iptables
