MySQL 8.0 配置mysql_native_password身份驗證插件的密碼

mysql8.0的默認密碼驗證不再是password。所以在創建用戶時，create user 'username'@'%' identified by 'password'; 客戶端是無法連接服務的。

 

方法一：

登錄MySQL后輸入：

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

FLUSH PRIVILEGES;

 

方法二：

編輯my.cnf文件，更改默認的身份認證插件。比如說：

vim /data/mysql/mysql_3306/my_3306.cnf

# 在[mysqld]中添加下邊的代碼
default_authentication_plugin=mysql_native_password

這個需要重啟服務才生效。
