MongoDB安装以及java开发入门<一>

1、Mongo数据库的安装。

    首先介绍一下Mongo数据库，Mongo数据库是一个面向集合的数据库，和传统的关系性的数据库是有一定的关系的。它是有c++编写的分布式数据库。

   它的安装步骤如下：

   1>>   下载Mongo数据库安装文件。下载地址为：http://www.mongodb.org/downloads   要根据你的计算机系统为准下载不同的安装文件。

   本人的操作系统的是Windows 7  32bit ，下载所得安装文件为：mongodb-win32-i386-2.0.2.zip。
   2>>  新建  E：\MongoDB\data，解压安装文件，找到bin目录，讲里面的所有的.exe文件全部拷贝到 E：\MongoDB\目录下。

   3>>   配置MongoDB数据库服务。

          打开命令行窗口：

C:\Users\DELL>e:

E:\>cd MongoDB

E:\MongoDB>mongod  --dbpath E:\MongoDB\data

OK MongoDB 数据库安装成功并顺利启动！

在浏览器地址栏敲下：http://localhost:27017/

你将会看到：

You are trying to access MongoDB on the native driver port. For http diagnostic access, add 1000 to the port number
