Configure port forwarding under CentOS to forward 80-port requests to 8080

Apache was deployed under Linux, for Security we started with a non-root user, but the 80 port number could not be accessed directly during domain binding. As we all know, under Unix, non-root users can not listen to the port number under 1024, this Apache server can not be bound to 80 port. So we need to use the port forwarding mechanism of Linux, and transfer the service request to port 80 to port 8080.
Run the command below the root account:

-t-A-p--80-j--to-port8080

In addition, if the firewall restarts, the command will become invalid, you can use the following command to save the rule in iptables.

service iptables save
