navicat连接报错 2059 - authentication plugin 'caching_sha2_password'

在mysql client中进入mysql数据库，输入以下命令：

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 
FLUSH PRIVILEGES; #刷新权限 

新测此时应该已经连接成功，如果不成功，则再重置下密码：alter user 'root'@'localhost' identified by 'newpassword';
