MySQL8.XX随未生成随机密码解决方案

一、客户端连接mysql，问题：1251 client does not support ...

二、解决

1.查看用户信息

备注：host为 % 表示不限制ip localhost表示本机使用 plugin非mysql_native_password 则需要修改密码

2.修改用户密码

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'mysql123456';
更新user为root，host为% 的密码为mysql123456

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'mysql123456';
更新user为root，host为localhost 的密码为mysql123456

mysql> select host,user,plugin,authentication_string from mysql.user;
