Question

我使用tunnel-ssh模块使用node.js建立与远程mysql数据库的连接。文档很差，我无法建立连接。以下是代码段：

var tunnel = require('tunnel-ssh')
var server = tunnel.tunnel(config.sshData, function(err, result) {console.log('connected'});

这是我的sshData对象。

config.sshData = {host : 'serverxyz.web-hosting.com', username : 'xyz', password : 'xyz',
srcPort: 3307, dstPort : 21098}

dstPort 21098是namecheap documentation建议的server.on('error', function(err) {});。

但是我收到超时错误，每当我添加这个片段时：

server.on is not a function

我收到错误putty。远程连接在SQLyog和ssh2上正常运行。任何关于如何建立成功连接的程序都会有很大帮助。谢谢！

使用指定的正确端口并使用<html> <head> <title>Toastr</title> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <script src="//ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script> <script src="//maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script> <script src="//cdnjs.cloudflare.com/ajax/libs/toastr.js/latest/js/toastr.min.js"></script> <link href="//cdnjs.cloudflare.com/ajax/libs/toastr.js/latest/css/toastr.min.css" rel="stylesheet" /> <link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css"> </head> <body> <div class="container-fluid"> <h1>Toastr bottom test</h1> </div> <script type="text/javascript"> $(function() { function Toast(type, css, msg) { this.type = type; this.css = css; this.msg = 'This is positioned in the ' + msg + '.

对namecheap文档存在误解。 21098是 ssh 端口，而不是数据库正在侦听的端口。要使用非标准ssh端口，您需要明确指定port值，如：

config.sshData = {
  host: 'serverxyz.web-hosting.com',
  port: 21098,
  username: 'xyz',
  password: 'xyz',
  dstPort: 3306
};

然后您应该能够连接到localhost:3306以访问您的远程数据库。
