javascript – Node.js websocket错误“错误:听EADDRNOTAVAIL错误:听EADDRNOTAVAIL”

作者:互联网

应用程序在localhost上正常工作.但是当它连接到服务器时它会出错.
我通过端口22连接服务器

这是错误

Error: listen EADDRNOTAVAIL Error: listen EADDRNOTAVAIL
at errnoException (net.js:904:11)
at Server._listen2 (net.js:1023:19)
at listen (net.js:1064:10)
at net.js:1146:9
at dns.js:72:18
at process._tickCallback (node.js:419:13)
at Function.Module.runMain (module.js:499:11)
at startup (node.js:119:16)
at node.js:906:3

任何帮助!

-update-

我运行netstat -tulpn | grep 22

结果:

 tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      683/sshd
 tcp6       0      0 :::22                   :::*                    LISTEN      683/sshd

但我运行netstat -tulpn | grep 80

什么都没显示.

任何Help.is这个服务器故障?

运行netstat -nlt

解决方法:

您正在使用二手港口.您必须更改端口,否则必须终止正在侦听端口的进程.打开终端并写入(示例):lsof -i:22或lsof -i:80或lsof -i:8000并终止进程的PID.

如何在total.js中更改侦听PORT?

>在/ app / config或/ app / config-release或/ app / config-debug中:

default-ip       : 127.0.0.1
default-port     : 8000

要么

// For e.g. Heroku
default-ip       : auto
default-port     : auto

>如果存在文件:release.js或debug.js:

var fs = require("fs");
var options = {};

// options.ip = "127.0.0.1";
// options.port = parseInt(process.argv[2]);
options.port = 8000;

>如果只存在index.js

// for development:
require('total.js').http('debug', { port: 8000 });

// or for production:
require('total.js').http('release', { port: 8000 });
