一台windows主机安装多个mysql服务

1、本地安装mysql

2、新建一个文件“mysql2”，将上面的所有目录全部复制到该文件夹中

3、修改mysql2中my-default.ini

# For advice on how to change settings please see# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the# *** default location during install, and will be replaced if you# *** upgrade to a newer version of MySQL.[mysqld]# Remove leading # and set to the amount of RAM for the most important data# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.# innodb_buffer_pool_size = 128M# Remove leading # to turn on a very important data integrity option: logging# changes to the binary log between backups.# log_bin# These are commonly set, remove the # and set as required.basedir =D:\Program Files\mysql2\mysql-5.6.16-winx64datadir =D:\Program Files\mysql2\mysql-5.6.16-winx64\dataport =3307# server_id = .....# Remove leading # to set options mainly useful for reporting servers.# The server defaults are faster for transactions and fast SELECTs.# Adjust sizes as needed, experiment to find the optimal values.# join_buffer_size = 128M# sort_buffer_size = 2M# read_rnd_buffer_size = 2M sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES 

4、创建mysql服务

mysqld install MySQL4  --defaults-file="D:\Program Files\mysql2\mysql-5.6.16-winx64\my-default.ini"

5、修改注册表

HKEY_LOCAL_MACHINE–>SYSTEM–>CurrentControlSet–>Services

修改值为：
“D:\Program Files\mysql2\mysql-5.6.16-winx64\bin\mysqld” –defaults-file=”D:\Program Files\mysql2\mysql-5.6.16-winx64\my-default.ini” MySQL4

6、启动mysql服务

7、连接数据库
