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
- Download installation file and JDBC driver
- 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:
- 在DOS下转到MySQL的安装目录的bin子目录下
- 在Windows中注册MySQL服务,输入命令: mysqld-nt –install
- 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
- 在DOS下转到MySQL的安装目录的bin子目录下
- 在DOS命令行输入命令:mysql
- 进入mysql数据库,SQL命令为:use mysql
- 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;
- 退出mysql客户程序:exit
- 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
- 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:
- 创建数据库:create database BookDB;
- 进入BookDB数据库:user BookDB
- 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
8. About the GUI tool for mysql you can download a 30 days trial version of SQLyog MySQL GUI on the site bellow :
