Question

以下Server.JS文件有什么问题？我们正在尝试将Deployd连接到Heroku并继续收到以下错误。我们正在使用Nitrous，我已经将mongoDB端口配置为5000.感谢任何帮助。万分感谢！

Server.JS

// require deployd
var deployd = require('deployd');

// configure database etc. 
var server = deployd({
  port: process.env.PORT || 5000,
  env: 'production',
  db: {
host: '0.0.0.0',
port: 5000,
name: 'database_name',
credentials: {
  username: 'username',
  password: 'password'
}
  }
});

// heroku requires these settings for sockets to work
server.sockets.server.set('transports', ["xhr-polling"]);

// start the server
server.listen();

// debug
server.on('listening', function() {
 console.log("Server is listening on port: " + process.env.PORT);
});

// Deployd requires this
server.on('error', function(err) {
  console.error(err);
  process.nextTick(function() { // Give the server a chance to return an error
process.exit();
  });
});

ERROR：

Answer 1

您为两台服务器使用相同的端口。您可以使用该命令杀死其中一个

netstat -ano|findstr "PID :5000"

5000 是您的端口。

{[错误：听EADDRINUSE ::: 5000]
