Node.js无法对MySQL 8.0进行身份验证
作者:互联网
我有一个Node.js程序,它使用root帐户连接到本地MySQL数据库(这不是生产设置).
这是创建连接的代码:
const mysql = require('mysql');
const dbConn = mysql.createConnection({
host: 'localhost',
port: 3306,
user: 'root',
password: 'myRootPassword',
database: 'decldb'
});
dbConn.connect(err => {
if (err) throw err;
console.log('Connected!');
});
它适用于MySQL 5.7,但自从安装MySQL 8.0后,我在启动Node.js应用程序时遇到此错误:
> node .\api-server\main.js

似乎root帐户使用新密码哈希方法:
> select User,Host,plugin from user where User="root";
+------+-----------+-----------------------+
| User | Host | plugin |
+------+-----------+-----------------------+
| root | localhost | caching_sha2_password |
+------+-----------+-----------------------+
…但我不知道为什么Node.js无法连接到它.我已经更新了所有的npm软件包,但仍然存在问题.
我想保留新密码哈希方法.我还可以使这个连接工作吗?我是否必须等待更新MySQL Node.js包,或更改我的设置?
解决方法:
MySQL 8.0使用新的默认身份验证插件 – caching_sha2_password – 而MySQL 5.7使用不同的 – mysql_native_password.目前,MySQL的社区Node.js驱动程序不支持新服务器插件的兼容客户端身份验证机制.
可能的解决方法是更改用户帐户的类型以使用旧的身份验证插件:
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'MyNewPass';
或者创建一个使用相同插件的不同的插件:
CREATE USER 'foo'@'localhost' IDENTIFIED WITH mysql_native_password BY 'bar';
有一个pull request正在准备妥善解决这个问题.
另一种选择是使用official MySQL Node.js连接器(完全公开:我是主要开发人员),它基于X Protocol并且已经支持新的身份验证模式.
