本文为Windows下配置mysql5.1免安装版

一、去官网下载下来压缩包。

二、将压缩包解压在某个位置 例如：E:/Java/mysql-5.1.73

三、配置my.ini文件

# Example MySQL config file for small systems.## This is for a system with little memory (<= M) 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	= 123port	= 3306socket	= MySQL# Here follows entries for some specific programs# The MySQL server[mysqld]basedir=E:/Java/mysql-5.1.73datadir=E:/Java/mysql-5.1.73/dataport	= 3306socket	= MySQLskip-lockingkey_buffer_size = 16Kmax_allowed_packet = 1Mtable_open_cache = 4sort_buffer_size = Kread_buffer_size = 256Kread_rnd_buffer_size = 256Knet_buffer_length = 2Kthread_stack = 128K# Don't listen on a TCP/IP port at all.

五、开始--运行 里面输入CMD 进入DOS下 输入 mysqld-nt -install，将mysql作为系统服务

启动MYSQL服务 net start mysql

停止MYSQL服务 net stop mysql

移除mysql服务 mysqld-nt --remove

如果安装成功但启动不了，报1067错，请检查my.ini文件。文件里面配置的路径要和实际的存放路径一致才行。
