Linux系统上安装mysql8.0及以上版本，远程授权失败的解决方式

1，创建用户的语句，可以新创建用户，也可以使用已有的用户，
create user ‘hh’@’%’ identified by ‘RRrr’;
2，授权语句，末尾不加 identified by ‘RRrr’ with grant option;
grant all privileges on . to ‘hh’@’%’ identified by ‘RRrr’ with grant option; ,
grant all privileges on . to ‘hh’@’%’
3，刷新权限
flush privileges;
