这篇文章给大家详细介绍了MySql 5.7.17免安装配置教程，首先大家需要先下载mysql 5.7.17 的安装包，然后解压，具体配置过程大家通过本文一起学习吧

1、下载mysql-5.7.17-winx64.zip安装包（链接：https://dev.mysql.com/downloads/mysql/）

2、解压安装包。

D:\DevelopTool\mysql-5.7.17-winx64 #解压目录

3、在解压目录下创建一个名为data的文件夹，用来存放数据

D:\DevelopTool\mysql-5.7.17-winx64\data

4、配置启动文件

　　把 D:\DevelopTool\mysql-5.7.17-winx64\my-default.ini 文件copy一份，重新命名为 my.ini ，修改里面的参数，如下：

				?

									# For advice on how to change settings please see

									# http://dev.mysql.com/doc/refman/5.7/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 = .....

									# datadir = .....

									# port = .....

									# server_id = .....

									#########################

									# basedir 为安装文件解压后的目录 ｜ basedir和datadir 可以使用相对路径

									# basedir=./..

									basedir=D:\\DevelopTool\\mysql-5.7.11-winx64

									# datadir 为用来存放数据的目录

									# datadir=./../data

									datadir=D:\\DevelopTool\\mysql-5.7.11-winx64\\data

									# port 为端口号

									port=3306

									# mar_connections为最大连接数

									max_connections=20

									character_set_server=utf8

									# 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 

									explicit_defaults_for_timestamp=true

									sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

5、初始化数据目录

				?

									mysqld --defaults-file="D:\DevelopTool\mysql-5.7.17-winx64\my.ini" --initialize-insecure

它会初始化 data 目录，在执行此命令前请先把data目录下的所有文件先删除，否则会失败

可以选择用 --initialize-insecure 或者 --initialize 来初始化，--initialize-insecure 初始化root密码为空，如果用 --initialize来初始化，会产生一个随机密码

　　执行成功后，在data目录下会生成mysql，perofrmance_schema，sys等目录文件

6、安装和启动mysql服务

				?

									#安装服务

									mysqld -install

									#启动服务

									net start mysql

									#进入mysql

									mysql -u root -p

									#移除mysql

									mysqld -remove
