MySQL在Windows下的免安装配置
1、软件的下载
到mysql的官方网站下载MySQL的解压包，mysql-noinstall-5.0.22-win32.zip
然后解压到C:\mysql里面就是MySQL数据库的全部内容。
2、配置
首先我们来看MySQL的根目录，里面有多个文件名如my-****.ini形式的文件，这就是MySQL配置
的样例文件，你可以选取其中一个，将其名字改为my.ini，MySQL启动的时候就是读取这个my.ini文
件来决定数据库的各项参数。
在my.ini文件中需要进行配置的主要是两个方面，一个是客户端，一个是服务器端。
* 客户端配置
# CLIENT SECTION
#-----------------------------------------------------
[client]
port = 3306
[mysql]
default-character-set = gbk
需要配置的主要是两项，一个是客户端端口，一个是默认的字符集(gbk就是设置成了中文)，这
里端口选用默认的3306，字符集可以根据需要修改为UTF-8或GBK。
* 服务器端配置
#SERVER SECTION
#-----------------------------------------------------
[mysqld]
port = 3306
basedir = "C:/mysql-5.0.51b-win32"
datadir = "C:/mysql-5.0.51b-win32/Data"
default-character-set = gbk
default-storage-engine = INNODB
max_connections = 100
max_allowed_packet = 16M
这里主要的是端口port，数据库安装目录(也就是我们解压的目录)basedir，数据库中数据
的存储路径(也就是你将来建立的Database和Table存放的位置)datadir。
其次就是字符集的设置，最大连接数的设置等，实际的设置项要根据开发与使用的需要，参
考解压目录中的几个样例文件进行取舍配置。
3、启动Mysql数据库
* 可以在Windows环境变量的path中先加入C:\mysql\bin这项，这样我们就可以
在命令行中直接使用mysql的各项命令了
* 进入命令行窗口，运行c:\mysqld-nt，这是查看Windows任务管理器，发现进程中多出来一个
mysqld-nt.exe，这说明数据库已经成功的启动的了。
* 此外，我们可以把数据库注册成一个服务，随着系统的启动而启动，具体命令如下：
c:\mysqld-nt -install
运行上面的命令后，就会在系统服务中注册了一个名字为MySQL，启动来性为Automatic的服务
，这个服务默认情况下是自动启动的。
可以通过命令行的防止停止或启动，如：
c:\net start MySQL启动）
c:\net stop MySQL（停止）
c:\mysqld-nt --remove MySQL（卸载服务）
4、使用MySQL数据库
* 由于我们在环境变量的path中加入了MySQL安装目录下的bin这项，所以可以直接使用MySQL命
令。
* 配置好上面信息并启动MySQL以后，默认的用户名root，密码为空，所以我们可以使用一下命
令登陆数据库：
c:\mysql -uroot -hlocalhost
回车以后会看到如下命令行状态：
mysql>
这说明已经成功登陆了MySQL数据库。
如果想为root用户加上密码，可以退出数据库mysql>quit，然后使用如下命令设置root用户的
密码：
c:\mysqladmin -uroot password 123456
这样就将root用户的密码修改为123456了，再次登陆数据库是就要用如下代码：
c:\mysql -uroot -p123456 -hlocalhost
至此，MySQL5数据库的配置就完成了，可以通过客户端或是程序来使用这个数据库了。
5、总结
MySQL提供了Install和NotInstall两种文件包的下载和安装方式，Install方式使用起来更为直
观和方便，而notInstall方式则能让你更加的了解MySQL数据库基本配置内容，所以各有利弊。从个
人角度来看，还是比较推荐notIntall的方式来使用Mhysql数据库，这样可以为在不同的平台下使用
MySQL奠定一个良好的基础。

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between

# the syntax is:
#
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
# where you replace <host>, <user>, <password> by quoted strings and
# <port> by the master's port number (3306 by default).
#
# Example:
#
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
# MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
# start replication for the first time (even unsuccessfully, for example
# if you mistyped the password in master-password and the slave fails to
# connect), the slave will create a master.info file, and any later
# change in this file to the variables' values below will be ignored and
# overridden by the content of the master.info file, unless you shutdown
# the slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
