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)

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 });
