Configure port forwarding in Centos to forward port 80 requests to port 8080

Apache is deployed in Linux. To ensure security, we use a non-root user to start the service. However, when binding a domain name, we cannot directly access port 80. As we all know, in unix, non-root users cannot listen to the port numbers below 1024, And the apache server cannot be bound to port 80. Therefore, we need to use the port forwarding mechanism in linux to forward all service requests to port 80 to port 8080.
Run the following command under the root account:

Iptables-t nat-a prerouting-p tcp -- dport 80-j REDIRECT -- to-port 8080

In addition, if the firewall is restarted, the command will become invalid. You can use the following command to save the rule to iptables.
