使用解压缩版的mysql
配置
MYSQL_HOME=E:\mysql-5.7.18-winx64
添加PATH：
Path=%MYSQL_HOME%\bin
里面的内容如下：（要更换其中的basedir和datadir）
[client] no-beep # pipe # socket=mysql port=3306 [mysql] default-character-set=utf8 # 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.

打开命令提示符以管理员身份运行，cd到E:\mysql-5.7.18-winx64\bin下
安装MySQL（其中的MySQL是安装服务器的名称，可以指定任何名称）
mysqld --install MySQL --defaults-file="E:\mysql-5.7.18-winx64\my.ini"
如果出现
The service already exists! The current server installed: E:\mysql-5.7.18-winx64\bin\mysqld MySQL 则移除原先的服务： mysqld -remove MySQL
并且清除data目录下的所有数据
安装成功后会在系统的服务组策中添加该服务，在使用时只需要开启即可。
mysqld --initialize-insecure --user=root（任意的用户名）
net start mysql
值得注意的是用命令安装的MySQL在Windows系统下默认服务名为mysql，默认密码为空。
mysql -u root -p
显示mysql>表示进入MySQL
