grant all privileges on *.* to root@"%" identified by ".";

回答: 根据引用\[1\]中的信息，你的语句"grant all privileges on *.* to root@"%" identified by ".";"报错了。根据引用\[2\]中的解决方法，如果你使用的是mysql8.0及以上版本，你应该使用以下语句来授予远程连接权限：create user root@'%' identified by '123456'; grant all privileges on *.* to root@'%' with grant option;。这样你就可以成功授予root用户在任何主机上的所有数据库的所有权限了。
