CentOS中使用yum安装配置MongoDB。
1.运行yum命令查看MongoDB的包信息
[root@vm ~]# yum info mongo-10gen
2.若无相关匹配信息，则需在 /etc/yum.repos.d/目录中增加 *.repo yum源配置文件
3.配置合适的yum源
vi /etc/yum.repos.d/10gen.repo
64位系统yum源配置
[10gen]name=10gen Repository
baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64
gpgcheck=0
32位系统yum源配置
[10gen]name=10gen Repository
baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/i686
gpgcheck=0 4.查看mongoDB的服务器包的信息
[root@localhost Desktop]# yum info mongo-10gen-server
