1、在MySQL官网下载好MySQL-5.7.16版本的zip压缩包，并解压到相关目录，如下：
2、配置环境变量，如下：
3、修改MySQL的配置文件，复制一份默认配置文件my-default.ini并改名为my.ini，如下：
用文本工具打开my.ini文件修改其中的basedir、datadir、port，其中， basedir为MySQL安装根路径，
datadir为MySQL安装根目录下的data文件夹路径（默认没有data目录，先不用管，后续会自动创建），port为默认端口号，
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 = G:\coder\database\mysql-5.7.16-winx64
datadir = G:\coder\database\mysql-5.7.16-winx64\data
port = 3312
# 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、注册MySQL服务，以管理员的身份运行cmd命令提示符窗口并进入到MySQL安装路径下的bin目录，并执行以下命令：
mysqld -install将mysql安装到windows服务（移除服务可以用mysqld --remove）；在执行mysql --initialize初始化data目录
（前文中配置的data目录在此步骤自动创建）。
5、启动MySQL服务，执行net start mysql（执行net stop mysql停止MySQL服务）如下：
6、登录root用户并更改root用户默认密码，root用户默认密码在data目录下*.err文件中，修改root用户默认密码命令：
alter user ‘root‘@‘localhost‘ identified with mysql_native_password by ‘新密码‘。如下：
注意：
1）mysqld –initialize-insecure：自动生成无密码的root用户；
2）mysqld –initialize：自动生成带随机密码的root用户；
3）mysqld -remove：移除mysqld服务；
4）net stop mysql：停止mysql服务；
5）如果报错，删除data文件夹，重新执行如下流程remove --> initialize --> install --> start
