1、首先复制一份my-default.ini，并改名为my.ini
2、修改my.ini配置
# 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.
[WinMySQLAdmin]
Server="D:/mysql/bin/mysqld.exe" #(这里是mysqld.exe的路径)
[client]
default-character-set = utf8 #(这里是客户端输出编码，我的网站编码是utf8的)
[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 = 600M #(Mysql数据缓存大小，根据自己内存大小跟需求调整)
# 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:/mysql #(Mysql目录路径)
datadir = d:/mysql/Database #(Mysql库路径，默认是跟目录下data文件夹，我的是自定义路径，注意这个路径改了的话一定要把原data目录下的文件复制过去，不然会报1067错误)
character-set-server=utf8 #(服务器默认字符，跟上面保持一直)
port = 3306 #(Mysql使用端口，默认3306)
server_id = mysqlgy
# 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 (Join操作使用内存)
# sort_buffer_size = 2M (排序使用内存)
# read_rnd_buffer_size = 2M (随机读取数据缓冲区使用内存)(以上三条根据自己的情况设置)
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES说明：
红色部分为添加，蓝色部分为修改。至此，my.ini参数配置教程完毕。
3、注册MySQL服务，使MySQL可以在服务项目中启动或关闭
1）进入安装目录in，执行：
D:mysqlin>mysqld -install mysqlgy
显示：Service successfully installed. 则注册服务成功。
如果要删除服务：
D:mysqlin>mysqld -remove mysqlgy
2）修改注册表：
HKEY_LOCAL_MACHINESystemCurrentControlSetServicesmysqlgyImagePath 修改为：
d:mysqlinmysqld --defaults-file="d:mysqlmy.ini" mysqlgy
注意不要有多余的空格，不然会报1053错误
这样配置就可以使用net start mysqlgy命令正常启动MySQL。
