问题描述
我是node.js的新手，正在尝试学习它.
我已经安装了node-mysql NPM模块.
在这里，我列出了访问mysql的代码:
I am new to node.js and trying to learn it.
I have installed node-mysql NPM module.
Here i have listed my code to access mysql :
// Include http module,
var http = require('http'),
// And mysql module you've just installed.
mysql = require("mysql");
// Create the connection.
// Data is default to new mysql installation and should be changed according to your configuration.
var connection = mysql.createConnection({
user: "root",
password: "",
database: "astitvabmt",
host: '127.0.0.1',
port: '3306',
_socket: '/var/run/mysqld/mysqld.sock'
});
// Create the http server.
http.createServer(function (req, res) {
// Attach listener on end event.
// Query the database.
connection.query('SELECT * FROM tbluser;',function(err, results, fields) {
if (err) throw err;
console.log("sachin : " + results);
var output = '<html><head></head><body><h1>Latest Posts</h1><ul><table border=1><tr>';
for (var index in fields) {
output += '<td>' + fields[index].name + '</td>';
}
output += '</tr>';
for (var index in results) {
output += '<tr><td>' + results[index].Recipe + '</td>';
output += '<td>' + results[index].Amount + '</td>';
output += '<td>' + results[index].Unit + '</td>';
output += '<td>' + results[index].Ingredient + '</td></tr>';
}
output += '</ul></body></html>';
res.writeHead(200, {'Content-Type': 'text/html'});
res.end(output);
});
// Listen on the 8080 port.
}).listen(8080);
console.log('Server mysqlJS running at 8080');
但是我收到错误消息:
sachin@ubuntu:/opt/lampp/htdocs/1nodeapp$ node mysql.js
Server mysqlJS running at 8080

我的mysql配置中没有跳过网络选项.
我已经在PC上安装了XAMPP.以前，我使用3306端口通过apache进行mysql连接.
I don't have skip-networking option in my mysql config.
I have installed XAMPP in my PC.Previously i use 3306 port for mysql connection using apache.
推荐答案
尝试使用socketPath参数代替_socket.
如此处所述 https://github.com/felixge/node-mysql#connection -选项
