.1、下载社区版本的服务端
解压包里是没有my-dafault.ini或自带my.ini文件，需自己创建放到解压目录下。编辑写入以下信息：
# 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.

以管理员权限打开cmd命令窗口，切换到”F:\mysql-5.7.21-winx64\bin”路径下，输入指令：
mysqld --initialize --user=mysql --console
该命令会在mysql-5.7.21-winx64目录下创建data文件夹及初始数据库，生成root用户和临时密码，红色标注部分多留意。
继续在窗口输入指令：
mysqld install MySQL --defaults-file="F:\mysql-5.7.21-winx64\my.ini"
路径是你my.ini文件的绝对路径，此时如果遇到错误没能安装成功，请用管理员身份运行cmd.exe程序再试，正确安装如下图：
在命令行窗口继续输入：
net start mysql
启动成功，会出现下面的截图。如果服务一直处于启动中，说明上一步的操作有误，核实my.ini文件路径是否正确
如需修改密码和配置远程连接，请参考我的安装mysql博客，博客链接https://www.cnblogs.com/mituxiaogaoyang/p/8655952.html
