    MySQL篇: - The world's most popular open source database http://www.mysql.com/ 多用户,多线程的强壮的关系数据库服务器

    http://supportopensource.iteye.com/blog/1415527 Windows7下MySQL5.5.20免安装版的配置
    MySQL Windows安装包说明:
    1、mysql-5.5.20-win32.msi:Windows 安装包,图形化的下一步下一步的安装。
    2、mysql-5.5.20.zip,这个是windows源文件,需要编译,对应的Linux源文件是mysql-5.5.20.tar.gz
    3、mysql-5.5.20-win32.zip,这个文件解包后即可使用,是编译好的windows32位Mysql。

    MySQL安装目录的bin目录下的mysql.exe程序是MySQL的客户程序,它支持在命令行输入SQL语句。

    在MySQL安装后,还有一个初始用户root,MySQL的安全验证机制要求用户为root重新设置口令 

    1. Download installation file and JDBC driver
    2. Unzip installation file and double click setup.exe will install MySQL 

    MySQL服务器即可以作为前台服务程序运行,也可以作为后台服务程序运行。

            前台服务程序运行方法:

    MySQL安装目录的bin目录下双击mysqld.exe – 最基本的MySQL服务器程序

                                                            Mysqld-nt.exe – NT/2000/XP平台的优化版本,支持命名管道

            后台服务程序运行方法:

    1. 在DOS下转到MySQL的安装目录的bin子目录下
    2. 在Windows中注册MySQL服务,输入命令: mysqld-nt –install
    3. 启动MySQL服务,输入命令:net start mysql  停止服务命令:net stop mysql  删除服务命令:mysqld-nt -remove

    也可以通过【控制面板】->【管理工具】->【服务】菜单来管理注册过的MySQL服务。

    当MySQL服务器启动后,按照以下步骤为root用户设置口令,并且创建新用户dbuser,口令为1234

    1. 在DOS下转到MySQL的安装目录的bin子目录下
    2. 在DOS命令行输入命令:mysql
    3. 进入mysql数据库,SQL命令为:use mysql
    4. 为root用户重新设置口令,新的口令为1234:

    update USER set PASSWORD=password(‘1234’) where USER=’root’;

    flush privileges;

    1. 退出mysql客户程序:exit
    2. 以root用户身份进入mysql客户程序:mysql -u root -p当系统提示输入口令时,输入1234
    3. 进入mysql数据库,创建一个新的用户dbuser,口令为1234,:

    use mysql;

    grant all privileges on *.* to dbuser@localhost identified by ‘1234’ with grant option;

    接下来创建BookDB数据库和BOOKS表,并向BOOKS表中插入数据,具体步骤如下

    1. 创建数据库:create database BookDB;
    2. 进入BookDB数据库:user BookDB
    3. 在BookDB数据库中创建BOOKS表:

    create table BOOKS(

    ID varchar(8) primary key,

     NAME varchar(24),

     TITLE varchar(96),

     PRICE float,

     YR int,

     DESCRIPTION varchar(128),

    SALE_AMOUNT INT);

         4.在BOOKS表中加入一些记录:

    insert into BOOKS values(‘201’, ‘孙卫琴’, ‘Java面向对象编程’, 65, 2006, ‘掌握Java’, 20000);

    ZIP文件解压缩后直接使用之绿色版本:

    1. Create my.ini from my-default.ini in your uncompressed mysql base directory (ex. D:/mysql)
    Modify the content of the file as bellow :

    [mysqld]

    # set basedir to your installation path
    basedir=D:/mysql

    # set datadir to the location of your data directory
    datadir=D:/mysql/data

    2. User the command bellow to start mysql service:
    D:mysqlinmysqld --console

    3. Test the mysql database service command:

    mysqlshow
    mysqlshow -u root mysql
    mysqladmin version status proc
    mysql test (Login test database)

    4. Change the password of root user

    mysqladmin -u root password "newpass"
    mysqladmin -u root password oldpass "newpass"

    5. Login mysql use root and password
    mysql -u root -p
    Input your password on the prompt

    After login the mysql server, you can create your own databases with sql.

    6. Change database to the test database
    use test;
    Show the tables of the database
    show tables;

    After change the database, you can create your table and insert some records into your table.

    7. Create windows service for mysql
    Stop mysql database service
    mysqladmin -u root -p shutdown
    Start a command prompt using admin privilege
    mysqld --install MySQL_gh
    Then you can see a service have been create in your windowns service management console.

    Delete mysql service
    sc delete MySQL_gh
