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
# 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"

key_buffer = 16M
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=
# MASTER_USER=
#
# where you replace
#
#
# 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
# (已注释),而是使用 CHANGE MASTER TO(见上文)
#
# 需要 2 到 2^32 之间的唯一 id - 1
#(与 master 不同)
# 默认为如果设置了 master-host,则为 2
# 但如果省略则不会充当从属设备
#server-id = 2
#
# 该从属设备的复制主设备 - 必需
#master -host =
#
# 从站连接到主站时用于身份验证的用户名
# - 必需
#master-user =
#
# 从站连接到时将使用的密码
# 主站 - 必需
#master-password =
#
# 主站正在侦听的端口。
# 可选 - 默认为 3306
#master-port =
#
# 二进制日志记录 - 从属服务器不需要,但推荐
#log-bin=mysql-bin

# 取消注释如果您使用的是 BDB 表,则以下内容

#bdb_max_lock = 10000
# 如果您使用 InnoDB 表,请取消注释以下内容

#innodb_data_file_path = ibdata1:10M:autoextend
#innodb_log_group_home_dir = C:/mysql/data/
#innodb_log_arch_dir = C:/mysql/data/
# 您可以将 .._buffer_pool_size 设置为 50 - 80 %

#innodb_buffer_pool_size = 16M
#innodb_additional_mem_pool_size = 2M

3、安装mysql服务
从MS-DOS窗口进入目录E:/myserver/mysql-5.0.37- win32/bin,如下运行命令:
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。
C:/>cd MySQL5
C:/MySQL5>cd bin
C:/MySQL5/bin>mysql -uroot -p
输入密码:
欢迎使用 MySQL 监视器。 命令以 ; 结尾或/g。
您的 MySQL 连接 ID 是 3
服务器版本:5.0.67-community-log MySQL Community Edition (GPL)
输入“help;”或“/h”寻求帮助。键入“/c”以清除缓冲区。
mysql> 使用 mysql
数据库已更改
