剛在官網裝好MySQL8.0後，我的cmd識別不了啟動數據庫的指令

需要cd到MySQL的bin目錄配置mysql

mysqld --install
mysqld --remove

mysql -u root -p
123456

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

之前的版本中加密規則是mysql_native_password,而在mysql8之後,加密規則是caching_sha2_password,直接去連接Navicat會報錯1251

解決問題方法有兩種,一種是升級navicat驅動,一種是把mysql用戶登錄密碼加密規則還原成mysql_native_password.

ALTER USER ‘root‘@‘localhost‘ IDENTIFIED BY ‘password‘ PASSWORD EXPIRE NEVER;          #修改加密規則 
ALTER USER ‘root‘@‘localhost‘ IDENTIFIED WITH mysql_native_password BY ‘password‘;     #更新一下用戶的密碼 
ALTER USER ‘kumata‘@‘%‘ IDENTIFIED WITH mysql_native_password BY ‘123456‘;             #修改kumata用戶密碼

done!!

MySQL8.0安裝連接Navicat的坑
