Ubuntu14.04下Mongodb（在线安装方式|apt-get）安装部署步骤（图文详解）（博主推荐）

　　不多说，直接上干货！

本博文介绍了MongoDB，并详细指引读者在Ubuntu下MongoDB的安装和使用。本教程在Ubuntu14.04下测试通过。

一、MongoDB介绍

　　MongoDB 是一个是一个基于分布式文件存储的数据库，介于关系数据库和非关系数据库之间，是非关系数据库当中功能最丰富，最像关系数据库的。他支持的数据结构非常松散，是类似json的bson格式，因此可以存储比较复杂的数据类型。Mongo最大的特点是他支持的查询语言非常强大，其语法有点类似于面向对象的查询语言，几乎可以实现类似关系数据库单表查询的绝大部分功能，而且还支持对数据建立索引。

二、安装MongoDB

　　MongoDB安装很简单，无需下载源文件，可以直接用apt-get命令进行安装。

首先，查看下你的操作系统的版本。

Use 'apt-get autoremove' to remove them.

　　安装完成后，在终端输入以下命令查看MongoDB版本：

root@zhouls-virtual-machine:~# mongo -version
MongoDB shell version: 2.4.

　　启动和关闭mongodb命令如下：

root@zhouls-virtual-machine:~# service mongodb start
start: Job is already running: mongodb
root@zhouls-virtual-machine:~# service mongodb stop
mongodb stop/waiting
root@zhouls-virtual-machine:~# 

　　默认设置MongoDB是随Ubuntu启动自动启动的。

　　输入以下命令查看是否启动成功：

pgrep mongo -l   #注意：-l是英文字母l，不是阿拉伯数字1

　　卸载MongoDB

root@zhouls-virtual-machine:~# sudo apt-get --purge remove mongodb mongodb-clients mongodb-server
