运行 grant all privileges on db.* to root; 但结果是：Query OK, 0 rows affected (0.00 sec) 这是为什么？ 谢谢！

用grant赋予某个账号在一个新主机上的访问权限，FLUSH privileges后，select user,password,host from user;可以看到权限已经赋予，用show grant 用户名@主机名;也能看到权限已经授予。但是从指定主机上却不能访问到mysql数据库 ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) 好像总是重启了服务器才能生效？不会吧？

請教各位，如何grant 權限給於某一特定schema 底下的所有 table。

grant ALL ON *.* 意识是“所有库.所有表”。 但是如果我创建一个用户，想让用户可以访问除mysql库的所有库，又要怎么写呢？

我是新手第一次用mysql按照书上的说明给设置密码结果忘记了FLUSH privileges;就退出mysql了。结果用mysql -u root -p，然后输入密码密码不管用了。请各位指点。谢谢了。
