javascript - Node 服务器无法连接mysql数据库connect ETIMEDOUT at Connection._handleConnectTimeout

Question

我无法连接 mysql 数据库。当我多次尝试启动 Node 服务器时，它会抛出数据库连接错误。

错误是:-

connect ETIMEDOUT
at Connection._handleConnectTimeout

Answer 1

使用以下内容创建文件 mysql_yourname:

const mysql = require('mysql');
const conn = mysql.createConnection({
  host: "localhost",
  user: "root",
  password: "pass",
  database: "databaase"
});
conn.connect(function(err) {  
    if(err) throw "There is no connection to the mysql server..." + err.message;  
    console.info("Connected!");  
}); 
exports.conn = conn;

然后在您的代码中需要该模块，您就会连接。

Connected!
