mysql远程连接权限grant all privileges on *.* to ‘root‘@‘%‘ identified by ‘123456‘ with grant option语句报错

grant all privileges on *.* to ‘root‘@‘%‘ identified by ‘123456‘ with grant option

只适用于mysql8.0之前的版本
之后采用这句:

create user root@'%' identified by '123456';
 
grant all privileges on *.* to root@'%' with grant option;
