1、先去MySQL官网下载。当前最新版是5.7.19，可能安装方法不同了，本人测试没有安装成功，若有安装成功的朋友，希望分享一下安装步骤。

2、将下载的压缩包解压出来，然后在“MySQL解压目录”中新建“data”文件夹。如下图：

3、将“my-default.ini”复制一份，并改名为：“my.ini”(如上图中的my.ini)，修改“basedir”指向“MySQL解压目录”，“datadir”指向MySQL解压目录下的“data”(data为第二步自己创建的)。 my.ini内容如下：

# 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 = .....

# 设置3306端口

port = 3306

# 设置mysql的安装目录

basedir = E:\Java\MySQL\mysql-5.7.17-winx64

# 设置mysql数据库的数据的存放目录

datadir = E:\Java\MySQL\mysql-5.7.17-winx64\data

# 允许最大连接数

max_connections = 200

# 服务端使用的字符集默认为8比特编码的latin1字符集

character-set-server = utf8

# 创建新表时将使用的默认存储引擎

default-storage-engine = INNODB

# 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、为了方便，配置一下环境变量。

4.1、新增系统变量：　　MYSQL_HOME ： 你的MySQL解压目录

4.2、配置Path环境变量：在Path中添加：%MYSQL_HOME%\bin

5、准备工作已完成，接下来就开始真正的安装了：

1、以管理员启动命令行，注意以”管理员“形式启动。

2、输入命令：mysqld --initialize-insecure

该命令是初始化数据库得到data目录，执行完之后你会发现data中生成了一些文件。

3、接着执行命令：mysqld --install　　若出现 Service successfully installed.则说明安装成功！

4、执行命令：net start mysql 启动MySQL服务，出现如下如说明服务已经成功启动

5、跟换MySQL root用户密码：

5.1　登录MySQL： mysql -uroot -p，首先是没有密码的

5.2　修改密码：set password for root@localhost = password('123456');

到这里就算全部安装完成。。。。。希望此文章可以对你有帮助。。。。。
