This so-called port number.

What about the port number? This thing is more mysterious than God.

Usually in the use of the building server or when using a software always encountered such a problem, such a software can not be opened, the error message translated is the port number conflict.

Change the port number, and you'll be fine.

It is like a toilet, a software can only occupy a pit, and the port number is the pit, if someone is using this pit, then you certainly can not rob with him, if you Rob, then the software will not output oh, so there is a hint, for this prompt solution then change a hole ╮(╯▽╰)╭

Port numbers range from 0 to 65535, such as 80 ports for browsing Web services, 21 ports for FTP services, and so on. Because of the large number of physical ports and logical ports, each port is numbered in order to differentiate the ports, which is the port number. So when the port number is occupied, we can go to the next pit Ah, in order to avoid the conflict to find a less common pit, and then you can safely squat up haha
