1 问题引入：直接使用“grant all privileges on *.* to 'root'@'%' with grant option;”给root用户赋予可远程连接权限时报
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'IDENTIFIED BY '123456' WITH GRANT OPTION' at line 1 错误
2 解决方案
use mysql;/*选中mysql数据库*/
update user set host='%' where user ='root';/*修改库中user表中，user用户的host=%（任意连接）*/
flush privileges;/*重新加载权限表*/
grant all privileges on *.* to 'root'@'%' with grant option;/*给root用户赋予远程连接权限*/
