第一种:

 增加一个用户test1密码为abc,让他可以在任何主机上登录,并对所有数据库有查询、插入、修改、删除的权限。首先用以root用户连入MYSQL,然后键入以下命令: 

  grant select,insert,update,delete on *.* to test1@“%” Identified by “abc”;

 

  但增加的用户是十分危险的,你想如某个人知道test1的密码,那么他就可以在internet上的任何一台电脑上登录你的mysql数据库并对你的数据可以为所欲为了,解决办法见例第二种: 

  第一种:增加一个用户test2密码为abc,让他只可以在localhost上登录,并可以对数据库mydb进行查询、插入、修改、删除的操作(localhost指本地主机,即MYSQL数据库所在的那台主机),这样用户即使用知道test2的密码,他也无法从internet上直接访问数

mysql> grant select,insert,update,delete on book.* to test2@localhost Identified by "abc";

 

  如果你不想test2有密码,可以再打一个命令将密码消掉。 

mysql> grant select,insert,update,delete on book.* to test2@localhost Identified by "";
