I know port 80 is one of well-know-port, but I am confused that if I build the website server process on other port except of 80, would it works when other client try to access this website server?

CodePudding user response：

Port 80 is the default port for http. So connecting to http://domain would in essence send you to http://domain:80 (by default).

Port 443 is the default for https and would work the same way as stated for http above.

Any other port would require the you to do url:port to connect to. There are definitely ways to get around this (like forwarding) but I don't see the need for it and I think it causes more issues than anything.

You would also need to make sure that the new port is open, forwarded and can receive connections.
