这篇文章主要介绍了windows中Mysql 5.7如何绿色安装，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。
1.1 下载
http://dev.mysql.com/downloads/mysql/ 下载地址,在下拉框中选择相应的版本
1.2 安装
下载下来的绿色安装包，直接解压为E:\mysql
1.3 编辑my.ini文件，
将mydefault.ini copy一份出来，就该其中的参数.
在mysqld中加入如下内容
basedir="E:\mysql\"
datadir="E:\mysql\data"
port=3306
#skip-grant-tables
E:\mysql\bin>mysqld --initialize
2016-09-06T13:57:01.349392Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is
deprecated. Please use --explicit_defaults_for_timestamp server option (see doc
umentation for more details).
2016-09-06T13:57:01.353393Z 0 [ERROR] --initialize specified but the data direct
ory has files in it. Aborting.
2016-09-06T13:57:01.354393Z 0 [ERROR] Aborting
出现了如上错误，是由于之前在 data文件夹中有文件导致的，删掉data下所有的文件，重新执行mysqld.exe –initialize命令ok
E:\mysql\bin>mysqld.exe --initialize
E:\mysql\bin>mysqld.exe --install

没办法修改密码吧
在mysqld下加入
skip-grant-tables
E:\mysql\bin>net stop mysql
MySQL 服务正在停止.
MySQL 服务已成功停止。
E:\mysql\bin>net start mysql
MySQL 服务正在启动 .
MySQL 服务已经启动成功。
