Django2.2连接MySQL报错Authentication plugin 'caching_sha2_password' cannot be loaded

Posted 2021-03-24 boirn

之前在升级网站的时候，runserver遇到了Authentication plugin ‘caching_sha2_password‘ cannot be loaded的报错。百度过后知道是因为mysql8采用了caching_sha2_password的加密方式，需要改回旧的mysql_native_password，在此附上修改方法：

mysql -u root -p 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

>FLUSH PRIVILEGES;  #刷新权限

然后切记要及时重置密码，不然旧密码会失效，退出后就进不去了！！！（被坑过的??‍♂???,重置密码搞了半天）

>ALTER USER ‘root‘@‘localhost‘ IDENTIFIED BY ‘12345678‘;
