MySQL8.0安装连接Navicat的坑

刚在官网装好MySQL8.0后，我的cmd识别不了启动数据库的指令

需要cd到MySQL的bin目录配置mysql

mysqld --install
mysqld --remove

mysql -u root -p
123456

use mysql
select host,user,authentication_string,plugin from user;        #查询

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,直接去连接Navicat会报错1251

解决问题方法有两种,一种是升级navicat驱动,一种是把mysql用户登录密码加密规则还原成mysql_native_password. 

ALTER USER 'root'@'localhost' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER;          #修改加密规则 
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';     #更新一下用户的密码 
ALTER USER 'kumata'@'%' IDENTIFIED WITH mysql_native_password BY '123456';             #修改kumata用户密码

done!!
