忽然打算进军node.js的开发领域，并且以此为工作，于是一不小心boss上投了几份简历，竟然恰好有公司回应，遂打算去试试，于是乎详细的介绍了我前端的本质，以及进军后端的决心，因为我想去试试呀，所以一不小心吹了小牛说自己可以三天拿下mongoDB，虽然事实是我其实今天上午之前对他还没有足够的了解，甚至从未接触过任何一款数据库产品，怎样呢，吹出去的牛就是熬着夜通着宵也要把他实现，这池子水不知是深是浅，感兴趣的小朋友可以跟我一起试试。下面我会尽可能详细的介绍学习mongo的全过程。
没带我的mac本子 所以暂时以Windows为例安装
大家可以根据自己的电脑型号自行下载
创建数据目录
在任意的一个盘新建一个空目录,我创建在了C盘里 但并不建议哈，我只是想快速的走一下过场。如 C:/data/db （这个就是你的dbpath）
c:\>mkdir datac:\>cd datac:\data>mkdir dbc:\data>cd db
运行mongoDB服务
找到mongodb安装目录,如果是自定义安装的是 C:/Program Files/MongoDB/Server/3.4bin 在bin文件运行
bin文件里边一般用到的就两个文件mongod.exe用来启动mongodb服务（启动之后你的数据库就可以使用了的意思）mongo.exe用来启动进入数据库（然后你就可以命令操作数据库的意思）
mongod --dbpath=刚创建的空目录,如mongod --dbpath=C:\data\db

这就挺好的可以参考
