本文详细介绍了MySQL数据库的安装、配置、启动及简单操作方法，包括客户端和服务端字符编码设置、数据库目录与引擎选择、启动与关闭数据库等步骤，并提供了JDBC连接示例和MySQLWorkbench的使用指南。

mysql下载回来之后解压到D:/mysql-5.1.57-win32，把D:/mysql-5.1.57-win32/bin加入到系统环境变量 Path 中。
然后需要简单的配置mysql数据库，把my-small.ini改名为 my.ini （其他的几个文件也可以直接拿过来修改一下名字），编辑文件 my.ini，其内容完整如下

# Example MySQL config file for small systems.

# This is for a system with little memory (<= 64M) where MySQL is only used

# from time to time and it's important that the mysqld daemon

# doesn't use much resources.

# MySQL programs look for option files in a set of

# locations which depend on the deployment platform.

# You can copy this option file to one of those

# locations. For information about these locations, see:

# http://dev.mysql.com/doc/mysql/en/option-files.html

# In this file, you can use all long options that a program supports.

# If you want to know which options a program supports, run the program

# with the "--help" option.

# The following options will be passed to all MySQL clients

[client]

#password = your_password

port = 3306

socket = /tmp/mysql.sock

default-character-set = utf8

# Here follows entries for some specific programs

# The MySQL server

[mysqld]

port = 3306

socket = /tmp/mysql.sock

default-character-set = utf8

basedir=D:/mysql-5.1.57-win32

datadir=D:/mysql-5.1.57-win32/data

default-storage-engine = MyISAM

# Don't listen on a TCP/IP port at all. This can be a security enhancement,

# if all processes that need to connect to mysqld run on the same host.

# All interaction with mysqld must be made via Unix sockets or named pipes.

# Note that using this option without enabling named pipes on Windows

# (using the "enable-named-pipe" option) will render mysqld useless!

#skip-networking

server-id= 1

# Uncomment the following if you want to log updates

#log-bin=mysql-bin

# binary logging format - mixed recommended

#binlog_format=mixed

# Uncomment the following if you are using InnoDB tables

#innodb_data_home_dir = C://mysql//data//

#innodb_data_file_path = ibdata1:10M:autoextend

#innodb_log_group_home_dir = C://mysql//data//

# You can set .._buffer_pool_size up to 50 - 80 %

# of RAM but beware of setting memory usage too high

#innodb_buffer_pool_size = 16M

#innodb_additional_mem_pool_size = 2M

# Set .._log_file_size to 25 % of buffer pool size

#innodb_log_file_size = 5M

#innodb_log_buffer_size = 8M

#innodb_flush_log_at_trx_commit = 1

#innodb_lock_wait_timeout = 50

[mysqldump]

quick

max_allowed_packet = 16M

[mysql]

no-auto-rehash

# Remove the next comment character if you are not familiar with SQL

#safe-updates

[myisamchk]

key_buffer_size = 8M

sort_buffer_size = 8M

[mysqlhotcopy]

interactive-timeout

重点配置：配置了客户端和服务器端的默认字符编码为utf8（default-character-set = utf8），防止输入中文数据时，保存后读取出来变成问号。mysql安装目录和数据库保存目录，默认数据库引擎为MyISAM。
3、运行中启动数据库

输入：mysqld.exe 就可以启动服务了

cmd中关闭数据库
命令mysqladmin -u root shutdown
MySQLWorkbench

可以使用官方提供的这个软件进行数据库操作。
JDBC连接MySQL

import java.sql.Connection;

import java.sql.DriverManager;

/**

*专门负责数据库打开和关闭操作的类

* @author Administrator

*

*/

public class DatabaseConnection {

private static final String DBDRIVER = "org.gjt.mm.mysql.Driver";

private static final String DBURL = "jdbc:mysql://localhost:3306/mldn";

private static final String DBUSER ="root";

private static final String DBPASSWORD = "";

private Connection conn = null;

public DatabaseConnection() throws Exception{

try {

Class.forName(DBDRIVER);

this.conn = DriverManager.getConnection(DBURL,DBUSER,DBPASSWORD);

} catch (Exception e) {

// TODO: handle exception

throw e;

}

}

public Connection getConnection(){

return this.conn;

}

public void close() throws Exception{

if(conn != null){

try {

this.conn.close();

} catch (Exception e) {

// TODO: handle exception

throw e;

}

}

}

}

推荐：mysql安装版在xp下的安装（win7没有尝试过）有每个步骤的截图
