即为mysql的自定义解压目录。
再在Path中添加 %MYSQL_HOME%\bin

将mysql注册为windows系统服务
操作如下:
1)从控制台进入到MySQL解压目录下的 bin 目录下:
2)输入服务安装命令:
mysqld install MySQL
安装成功后会提示服务安装成功。
输入net start MySql测试是否安装成功。
移除服务命令为:mysqld remove

如果以前安装过MySql或其他原因,cmd会提示找不开服务,这是因为可执行文件路径不对,清理注册表,删除Program Data下MySql目录,重启电脑,会解决。

背景知识:
mysqld.exe 和 mysql.exe 有什么区别?
mysqld.exe 是MySQL后台程序(即MySQL服务器)。要想使用客户端程序,该程序必须运行,因为客户端通过连接服务器来访问数据库。
mysql.exe 是MySQL自带的命令行客户端工具,是交互式输入SQL语句或从文件以批处理模式执行它们的命令行工具。
简单来说:mysqld是用来启动mysql数据库的命令,mysql则是打开并执行sql语句的命令。
mysqld.exe 命令讲解
Windows下通过mysqld.exe 命令行安装MySQL服务例子:
1. 在“开始”->“运行”中输入cmd
2. cd进入到mysql安装的bin目录
3. 安装mysql服务:mysqld --install
可以指定服务的名字:mysqld --install MySQL5
默认是开机自动运行服务,如果开机不自动启动,可写为:mysqld.exe --install-manual
带配置文件写法:mysqld --install 系统服务名 --defaults-file=你的mysql配置文件的路径
例如:mysqld --install MySQL5 --defaults-file=d:\mysql\my.ini
4. 启动:net start mysql
5. 关闭:net stop mysql
6. 删除mysql服务: mysqld --remove
也可以指定服务的名字。mysqld --remove MySQL5
