1.下载jdbc驱动：

http://dev.mysql.com/downloads/connector/j/

2.增加jdbc的jar包至项目的libs文件夹并build path

2.改动环境变量：export PATH=/usr/local/mysql/bin/:${PATH}

3.默认root@localhost没有password

4.改动password：

命令行：mysqladmin -u root -p  password root

MYSQL环境中的命令：

mysql> UPDATE mysql.user SET password=PASSWORD(’新密码’) WHERE User=’root’;

mysql> FLUSH PRIVILEGES;

5.重新启动mysql

/Library/StartupItems/MySQLCOM/MySQLCOM restart

停止mysql

/Library/StartupItems/MySQLCOM/MySQLCOM stop

6.进入test

mysql -u root -proot

7.新建一张測试表

create table table1 (username varchar(20) primary key,password integer);

insert into table1 values(‘yyz‘,123456);

insert into table1 values(‘pengkv‘,123456);

insert into table1 values(‘pj‘,123456);

insert into table1 values(‘cl‘,123456);

9.书写代码
