Mongodb在CentOS 6.4下的安装
因为公司今天要用到Mongodb数据库，之前没有接触过，接触更多的都是MySQL；然后去网上找相关的文档教程，大致的看下安装类似于MySQL的安装；本博文借鉴博友的博客，谢谢博友的分享操作系统：CentOS 6.4 x86-64
软件版本：mongodb-linux-x86_64-2.6.1.tgz
Mongodb官网下载链接地址：http://www.mongodb.org/dr//fastdl.mongodb.org/linux/mongodb-linux-x86_64-2.6.1.tgz/download
Mongodb概述：
MongoDB是为处理大数据而生的一款面向文档的数据库，由10gen公司开发和维护
NoSQL数据库与传统的关系型数据库相比，它具有操作简单、完全免费、源码公开、随时下载等特点
其实NoSQL，我们大家一定对Redis熟悉吧！它也是NoSQL数据库，是作为缓存数据库系统不二的选择；
1、查看操作系统的版本

# cat /etc/centos-release
CentOS release 6.4 (Final)
# uname -r
2.6.32-358.el6.x86_64
2、将下载后的二进制通用包上传到指定目录
1

# ll
total 112060
-rw-r--r--. 1 root root 114747467 Jun32014 mongodb-linux-x86_64-2.6.1.tgz
3、解压该文件到特定目录,并建立软件接
1
2
tar -xf mongodb-linux-x86_64-2.6.1.tgz -C /usr/local
ln -sv mongodb-linux-x86_64-2.6.1 mongodb
