MongoDB官网下载安装：https://www.mongodb.com/download-center#community
我下载的是安装包，解压，添加环境变量后，运行mongod --dbpath D:\my\mongodb\database报错，有两个原因：
1.运行路径不对
运行路径是压缩包解压的bin目录下D:\my\mongodb\mongodb-win32-x86_64-2008plus-ssl-4.0.6\bin
2.命令中的路径要加引号mongod --dbpath "D:\my\mongodb\database"，不能是mongod --dbpath D:\my\mongodb\database
