macjdbc連接mysql

1.下載jdbc驅動：

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

2.加入jdbc的jar包至項目的libs目錄並build path

2.修改環境變量：export PATH=/usr/local/mysql/bin/:${PATH}

3.默認root@localhost沒有密碼

4.修改密碼：

命令行：mysqladmin -u root -p password root

MYSQL環境中的命令：

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

mysql> FLUSH PRIVILEGES;

5.重啟mysql

/Library/StartupItems/MySQLCOM/MySQLCOM restart

停止mysql

/Library/StartupItems/MySQLCOM/MySQLCOM stop

6.進入test

mysql -u root -proot

7.新建一張測試表

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.書寫代碼
