Mysql创建数据库和独立数据库帐号方法介绍

mysql>exit;
@>mysql -u phplamp -p
@>输入密码
mysql>登录成功

//登录MYSQL（有ROOT权限）。我里我以ROOT身份登录.
@>mysql -u root -p
@>密码
//首先为用户创建一个数据库(phplampDB)
mysql>create database phplampDB;
//授权phplamp用户拥有phplamp数据库的所有权限。
>grant all privileges on phplampDB.* to phplamp@localhost identified by '1234';
//刷新系统权限表
mysql>flush privileges;
mysql>其它操作

/*
如果想指定部分权限给一用户，可以这样来写:
mysql>grant select,update on phplampDB.* to phplamp@localhost identified by '1234';
//刷新系统权限表。
mysql>flush privileges;
