Should the `port` field in server part need to be `required`?

It seems the port field can be optional.

Thanks for following this project.
sure, port field should be optional.

To implement this feature, you need to change the syntax in the Lexer. (see in https://github.com/stephenwzl/enginx/blob/master/Lexer/enginx.y#L43)
Then change function enginx_create_server to make port optional at runtime.

I have stopped developing new features for this project, but it is still used by some App with millions of users, so don't worry about its stability.

Got it, thanks.
