无法将 Node.js 连接到 Mac OS 上的 XAMPP MySQL 服务器
Trouble connecting Node.js to XAMPP MySQL server on Mac OS
我一直在努力使用 MySql 模块将 Node.js 连接到我的 MySql 数据库。数据库正在 运行 本地通过 XAMPP 在我的 Mac 上。这是我的连接脚本
var mysql_con = mysql.createConnection({
socketPath: '/opt/lampp/var/mysql/mysql.sock',
//port: '8080',
host: '192.168.64.2',
user: 'root',
password: '',
database: 'twitch_versus'
});
mysql_con.connect(function (err) {
if(err) {
console.log('mysql connect error: ' + err.stack);
return;
}
console.log('mysql connected as ' + mysql_con.threadId);
});
运行 这个配置给出了这个错误
mysql connect error: Error: connect ENOENT /opt/lampp/var/mysql/mysql.sock

# 2) Set the variables below. However, in case you choose this method, then

# if you mistyped the password in master-password and the slave fails to
# connect), the slave will create a master.info file, and any later
# change in this file to the variables' values below will be ignored and
