Windows上安装MongoDB步骤

事前准备：

1.在mongoDB官网下载.msi文件，我下的是社区版，下载地址：https://www.mongodb.com/download-center#community

2.点击msi文件安装mongoDB，默认安装在C:\Program Files\MongoDB\Server\3.2

3.添加安装路径到环境变量，也就是把C:\Program Files\MongoDB\Server\3.2\bin添加到环境变量里面。关于环境变量：右键点击计算机，选择属性，点击系统高级设置，点击高级里面的环境变量，找到变量名为Path的一行点击编辑，将C:\Program Files\MongoDB\Server\3.2\bin添加到最后，记得跟前面的要用分号隔开

方法一：

1.建立mongoDB的数据和log文件夹。比如在D盘建立文件夹mongoDB，在其下分别建立子文件夹data和log。

2.cmd打开命令提示符窗口，输入mongod --dbpath "D:\mongoDB\data" --logpath "D:\mongoDB\log\mongo.log" --install --serviceName "mongoDB",回车

3.net start mongDB,会提示mongoDB服务已经启动成功,默认监听的TCP端口是27017，可以在浏览器地址栏输入localhost:27017,会看到出现:

It looks like you are trying to access MongoDB over HTTP on the native driver port.

4.使用mongo命令进入mongo shell进行数据库的操作

5.使用net stop mongDB关闭服务

方法二：

1.建立mongoDB的数据和log文件夹以及配置文件mongo.config。比如在D盘建立文件夹mongoDB，在其下分别建立子文件夹data和log以及配置文件mongo.config。

2.编辑mongo.config:

输入：dbpath=D:\mongoDB\data

logpath=D:\mongoDB\log\mongo.log

storageEngine=mmapv1

......（根据自己的需要添加配置的项目）

注意配置项目之间要换行

3.打开cmd命令窗口，输入：mongod  --config D:\mongoDB\mongo.config

4.打开mongo.log可以看到如下内容即为服务启动成功

5.另开一个cmd窗口，输入mongo,就可以连接到mongodb数据库了

提示：推荐使用第二种方法，第一种在32位Windows下很容易出现问题，别忘了配置引擎
