MongoDB 分布式文件存储的数据库

MongoDB 是一个基于分布式文件存储的数据库。由C++语言编写。旨在为WEB应用提供可扩展的高性能数据存储解决方案。



[root@vm ~]# yum info mongo-10gen


说明你的centos系统中的yum源不包含MongoDB的相关资源,所以要在使用yum命令安装MongoDB前需要增加yum源,也就是在 /etc/yum.repos.d/目录中增加 *.repo yum源配置文件,以下分别是针对centos 64位和32位不同的系统的MongoDB yum 源配置内容:


For 64-bit yum源配置:

vi /etc/yum.repos.d/10gen.repo

name=10gen Repository

For 32-bit yum源配置:

vi /etc/yum.repos.d/10gen.repo

name=10gen Repository



$ uname -a

含有x86_64的那说明是64位的,例如我的centos6.0 64bit系统执行这个命令后显示:

Linux vm.centos6 2.6.32-71.29.1.el6.x86_64 #1 SMP Mon Jun 27 19:49:27 BST 2011 x86_64 x86_64 x86_64 GNU/Linux
