MySQL8.0登录提示caching_sha2_password问题解决方法

修改my.cnf

[mysqld]
default_authentication_plugin = mysql_native_password

重启mysql

或者登陆mysql，使用alter语句修改

use mysql
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';

查看结果：

mysql> SELECT Host, User, plugin from user;
+-----------+------------------+-----------------------+
| Host      | User             | plugin                |

| localhost | mysql.infoschema | caching_sha2_password |
| localhost | mysql.session    | caching_sha2_password |
| localhost | mysql.sys        | caching_sha2_password |
| localhost | root             | mysql_native_password |
