1：先上官网：http://www.mongodb.org/downloads 下载最新的：
下载完后文件名为：mongodb-win32-x86_64-2.4.6.zip 解压到当你要安装的目录，然后我把目录名给改短了一下，叫mongodb246，放在了e盘下。 2：用cmd运行目录下bin下的mongod.exe来安装服务：
--reinstall 是重新安装，首次安装没有开--reset参数，所以用了重装参数。
--install 是安装。
另外中间我犯了一个错，把logpath 弄成了文件夹（本应该是一个文件名称），结果搞了一个失败的服务，还删不掉。。悲催。
（后来重启电脑后，那个删不掉的服务自己消失了）
具体的参数如下，比较多，简单的就是像我上面的图一样，参考着写就可以了：
如果看不懂E文，可以复制拿去Google翻译文档。

安装好后，浏览器运行：http://127.0.0.1:28017 打开有东西就说明装上了，按理是localhost:端口可上的，不知我电脑是有缓存还是咋的，没反应，换上IP刷新就好了。
打开是这么个界面：
目前着实没看出什么信息，基本正常到此，可能会被卡住，不知道后续干什么了。
3：链接进入命令模式：
正常来说，在cmd命令下，运行E:>mongodb246binmongo.exe，（路径自己弄对）直接就连上了：
之后可以运行点命令测试下，如：
相关基础命令可以看：http://docs.mongodb.org/manual/tutorial/getting-started/
再接下来，就是怎么用代码开发的问题了
