==================添加用户及授权部分===================

摘自:Mysql创建、删除用户

2.3 授权test用户拥有testDB数据库的所有权限(某个数据库的所有权限):

   mysql>grant all privileges on testDB.* to test@localhost identified by '1234';

  mysql>flush privileges;//刷新系统权限表

  格式:grant权限 on 数据库.* to 用户名@登录主机 identified by "密码";

2.4 如果想指定部分权限给一用户,可以这样来写:

  mysql>grant select,update on testDB.* to test@localhost identified by '1234';

2.5 授权test用户拥有所有数据库的某些权限:

  mysql>grant select,delete,update,create,drop on *.* to test@"%" identified by "1234";

//test用户对所有数据库都有select,delete,update,create,drop 权限。

 //对localhost授权:加上一句grant all privileges on testDB.* to test@localhost identified by '1234';即可。
