docker 中安装mysql8之后无法远程连接的问题caching-sha2-password

#修改加密规则 

ALTER USER 'root'@'%' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER; 

#更新一下用户的密码 

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'password';

#刷新权限

FLUSH PRIVILEGES;

#重置密码

alter user 'root'@'%' identified by '123qwe'

注意：上面  % 是设置远程连接，本地连接设为localhost即可
