一、下载MySQL
http://www.mysql.org/downloads
我下载的是mysql-noinstall-5.0.67-win32.zip
二、安装过程
1、解压缩 mysql-noinstall-5.0.67-win32.zip 到一个C盘，重新命名为 MySQL5 。
假定MYSQL_HOME=C:\ MySQL5
2、编辑mysql的运行配置文件my.ini，如果没有，可以拿my-medium.ini复制然后更名成 my.ini
复制代码代码如下:
# Example MySQL config file for medium systems.
#
# This is for a system with little memory (32M - 64M) where MySQL plays
# an important part, or systems up to 128M where MySQL is used together with
# other programs (such as a web server)
#
# You can copy this file to
# /etc/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is C:\mysql\data) or
# ~/.my.cnf to set user-specific options.
#
# 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
# Here follows entries for some specific programs
# The MySQL server
[mysqld]
basedir = "C:\MySQL5"
datadir = "C:\MySQL5\data"
default-character-set=utf8
port = 3306

max_allowed_packet = 1M
table_cache = 64
sort_buffer_size = 512K
net_buffer_length = 8K
read_buffer_size = 256K
read_rnd_buffer_size = 512K
myisam_sort_buffer_size = 8M
# 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
# (via the "enable-named-pipe" option) will render mysqld useless!

# Replication Master Server (default)
# binary logging is required for replication
log-bin=mysql-bin
# required unique id between 1 and 2^32 - 1
# defaults to 1 if master-host is not set
# but will not function as a master if omitted
server-id = 1
# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
# 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
# but will not function as a slave if omitted
#server-id = 2
#
# The replication master for this slave - required
#master-host = <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user = <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password = <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port = <port>
#
# binary logging - not required for slaves, but recommended

3、安装mysql服务
从MS-DOS窗口进入目录E:\myserver\mysql-5.0.37-win32\bin，运行如下命令：
mysqld --install mysql --defaults-file=C:\MySQL5\my.ini
4、启动mysql数据库
还在上面的命令窗口里面，输入命令：net start mysql
这样就启动了mysql 服务。
5、停止服务
执行 net stop mysql 即可
6、删除服务
执行mysqld --remove mysql 即可
7、修改密码
以上安装完毕之后，默认的root用户密码为空的。为了安全起见，需要设置一个root用户的密码。
复制代码代码如下:
<STRONG><SPAN style="COLOR: #ffffff" style="COLOR: #ffffff">C:\>cd MySQL5
C:\MySQL5>cd bin
C:\MySQL5\bin>mysql -uroot -p
Enter password:
