Can'；t将Node.js连接到远程数据库
根据教程，我尝试使用Node.js连接到我的MariaDB数据库：Can'；t将Node.js连接到远程数据库,node.js,mariadb,Node.js,Mariadb,根据教程，我尝试使用Node.js连接到我的MariaDB数据库： const mariadb = require('mariadb'); const pool = mariadb.createPool({ host: 'myhost.com', user:'root', password: 'password', database: 'db_p', connectionLimit: 2 }); async function asyn
const mariadb = require('mariadb');
const pool = mariadb.createPool({
host: 'myhost.com',
user:'root',
password: 'password',
database: 'db_p',
connectionLimit: 2
});
async function asyncFunction() {
let conn;
try {
console.log('establishing connection')
conn = await pool.getConnection();
console.log('established')
const rows = await conn.query("SHOW TABLES");
console.log(rows);
} catch (err) {
console.log(err)
throw err;
} finally {
if (conn) return conn.end();
}
}
establishing connection

过去两年我一直在用JS编程，但我对Node.JS还不熟悉，我认为它应该是现成的。有人吗？问题是，在phpMyAdmin中，我没有添加我的家庭ip地址以便连接。对于那些刚刚开始使用它的用户-您可以创建多个具有相同名称和密码的用户，这样您就可以从多个IP访问（如
localhost：：1127.0.0.1我添加了其他具有相同凭据的用户指向我的IP，解决了问题。因此与数据库的连接超时。您可以通过其他方式（如命令行客户端）从同时运行节点代码的计算机访问数据库吗？不完全可以。我可以访问phpMyAdmin，之所以使用Node是因为我们的开发人员走了，我需要创建连接到数据库的微服务，这样我们就不会被蒙在鼓里。PHP代码指向
