two。 How to access the server directly through the ip address or domain name without adding the port number 8080

Reason: apache is deployed under Linux. For security, we use non-root users to launch, but the 80 port number cannot be accessed directly when the domain name is bound. As we all know, under unix, non-root users cannot listen to port numbers below 1024, and the apache server cannot be bound under port 80. Therefore, we need to use linux's port forwarding mechanism to transfer all service requests to port 80 to port 8080.

What should we do? Just run the command under your root account:

Iptables-t nat-A PREROUTING-p tcp-- dport 80-j REDIRECT-- to-port 8080

Transfer all service requests to port 80 to port 8080.

In addition, if the firewall is restarted, the command will fail, and you can use the following command to save the rule to iptables.
