连接到数据库时出错：{Error：connect ENOENT /var/run/mysqld/mysqld.sock

我在连接节点js上的MySQL新，我有一个错误。

这是我的整个代码：

var express = require('express'); var http = require('http'); var path = require('path'); var jquery = require('jquery'); var app = express(); var connection = require('express-myconnection'); var mysql = require('mysql'); app.set('port', process.env.PORT || 6900); app.set('views', path.join(__dirname, 'views')); app.set('view engine', 'ejs'); app.use(express.logger('dev')); app.use(express.json()); app.use(express.urlencoded()); app.use(express.methodOverride()); app.use(express.static(path.join(__dirname, 'public'))); // development only if ('development' == app.get('env')) { app.use(express.errorHandler()); } app.use( connection(mysql,{ host: '10.10.124.98', user: 'root', password : 'NLPZJNWF', port : 6900, //port mysql database:'areas', socketPath: '/var/run/mysqld/mysqld.sock' }) //or single ); app.get('/', function(req, res){ req.getConnection(function(err,connection){ var query = connection.query('SELECT * FROM areas2015',function(err,rows) { if(err) { console.log("Error Selecting : %s ",err ); } else console.log("success"); }); }); }); app.use(app.router); http.createServer(app).listen(app.get('port'), function(){ console.log('Express server listening on port ' + app.get('port')); }); 

而我有这个错误：

 error when connecting to db: { Error: connect ENOENT /var/run/mysqld/mysqld.sock at Object.exports._errnoException (util.js:1018:11) at exports._exceptionWithHostPort (util.js:1041:20) at PipeConnectWrap.afterConnect [as oncomplete] (net.js:1086:14) -------------------- at Protocol._enqueue (F:\New folder\Proj try\node_modules\mysql\lib\protocol\Protocol.js:110:48) at Protocol.handshake (F:\New folder\Proj try\node_modules\mysql\lib\protocol\Protocol.js:42:41) at Connection.connect (F:\New folder\Proj try\node_modules\mysql\lib\Connection.js:99:18) at Timeout.handleDisconnect [as _onTimeout] (F:\New folder\Proj try\node_modules\express-myconnection\lib\express-myconnection.js:12:17) at ontimeout (timers.js:386:14) at tryOnTimeout (timers.js:250:5) at Timer.listOnTimeout (timers.js:214:5) code: 'ENOENT', errno: 'ENOENT', syscall: 'connect', address: '/var/run/mysqld/mysqld.sock', fatal: true } 

我该如何解决？
