Mysql 解决1251- Client does not support authentication protocol requested by server...的问题

一、问题描述

使用Navicat客户端连接本地mysql，报错：1251- Client does not support authentication protocol requested by server;consider upgrading Mysql client。

二、查看用户信息

打开命令行小黑屏，进入MySQL的bin目录，然后输入mysql -u root -p，输入密码，登录成功

执行SQL查询用户信息

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

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

三、问题原因

上网搜索解决方案，网上说出现这种情况的原因是：mysql8 之前的版本中加密规则是mysql_native_password,而在mysql8之后,加密规则是caching_sha2_password,

解决问题方法有两种：

方法1.升级navicat驱动；

方法2.把mysql用户登录密码加密规则还原成mysql_native_password.

这里采用方法2解决，具体操作步骤如下。

四、解决

在命令行输入如下命令，修改密码。

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';
更新user为root，host为% 的密码为123456ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';
更新user为root，host为localhost 的密码为123456

或者

ALTER USER 'root'@'localhost' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER; #修改加密规则 （这行我没有写，不过貌似也可以）ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password'; #更新一下用户的密码 FLUSH PRIVILEGES; #刷新权限

再次查询用户信息

再次在Navicat中连接mysql，连接成功
