我是 node.js 的新手并试图学习它。
我已经安装了 node-mysql NPM 模块。在这里，我列出了访问 mysql 的代码：
// 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');
但我收到错误：
sachin@ubuntu:/opt/lampp/htdocs/1nodeapp$ node mysql.js

我的 mysql 配置中没有跳过网络选项。
我已经在我的 PC 中安装了 XAMPP。以前我使用 3306 端口使用 apache 进行 mysql 连接。
