NodeJS MySQL 客户端不支持认证协议

Question

When I am trying to connect with mysql 8.0 I am getting this error. How can I fix this?

code: 'ER_NOT_SUPPORTED_AUTH_MODE',
errno: 1251,
sqlMessage: 'Client does not support authentication protocol requested by server; 
consider upgrading MySQL client',
sqlState: '08004',
fatal: true

Answer 1

Try change the password as below:

ALTER USER 'root'@'localhost' IDENTIFIED BY 'your new password'; 
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'your new password';

Answer 2

ALTER USER 'root'@'localhost' IDENTIFIED BY 'password'; 
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';

FLUSH PRIVILEGES;

"password" is that you have to change the password you already have or you will modify it for a new one

Answer 3

You're probably using mysql npm package which currently doesn't support MySQL 8.0 new default authentication plugin caching_sha2_password.. You can just update your npm package to mysql2 : const mysql = require('mysql2')
