Node.JS：重用套接字？

Question

I tries to execute this script:

require('net').createServer().listen('/tmp/test');

First time script runs successfully, but on the second start node.js throwing error: Error: listen EADDRINUSE

Is there any way to reuse sockets (unix and tcp too)?

Answer 1

Apparently your script/listener/server from the first call is still running. You have to kill the script/process that is listening in order to use the same port again.

Answer 2

huh?

Node is already listening to 'tmp/test' , how would it listen to it again?

Like you cannot allow two applications to listen on ONE PORT, so is with SOCKET. One should only be allowed by one.

Answer 3

The 'right' way (according to the Node.js docs) is to close the server with server.close() , this removes the creates domain socket from the file system.

So if you run the server again you don't have the 'EADDRINUSE' error because it recreates|removes a new domain socket each time.

On windows (with named pipes) we don't have this problem, once the server process is closed the OS automatically removes the created named pipe
