mysql一机多实例安装记录

拷贝文件

拷贝mysql-5.7.9-win64目录下的my-default.ini分别到whole、one、two目录下，更名为my.init。

以whole库 为例说明，one库和two库做相应调整即可。

1、编写\instance\whole\my.init

innodb_buffer_pool_size = 128M

basedir = E:\mysql\mysql-5.7.9-winx64

datadir = E:\mysql\mysql-5.7.9-winx64\instance\whole\data

port = 3309

server_id = 3

对于分库two要注意：

3、Initializing the Data Directory 

mysqld --defaults-file=E:\mysql\instance\whole\my.ini --initialize --console
