第六周书面作业---CentOS下使用yum安装MongoDB
中级会员, 积分 380, 距离下一级还需 120 积分
论坛徽章:2
一、环境：
1.系统环境：
主机：win7
虚拟机：Vmware Workstation 6.5
OS系统：CentOS Linux release 5.6 (Final) 32位
[root@localhost etc]# cat issue
CentOS release 5.6 (Final)
Kernel \r on an \m
[root@localhost etc]# getconf LONG_BIT
2.软件版本
mongoDB版本：2.4.5& &
二、centos下安装mongodb
1.检测yum源是否有mongodb
[root@localhost ~]# yum info mongo-10gen
Loaded plugins: fastestmirror, protectbase
Determining fastest mirrors
* epel: mirrors.
* extras: mirrors.
* updates:

0 packages excluded due to repository protections
Error: No matching Packages to list
[root@localhost ~]#
2.增加yum源
vi /etc/yum.repos.d/10gen.repo，输入下面的语句：
[root@localhost ~]# vi /etc/yum.repos.d/10gen.repo
name=10gen Repository
baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/i686
gpgcheck=0
第一个错误是centos是32位，结果按照老师的地址下载的是64位的，调整
[root@localhost ~]# yum info mongo-10gen-server
Loaded plugins: fastestmirror, protectbase
Loading mirror speeds from cached hostfile
* epel: mirrors.
* extras: mirrors.
* updates:
10gen& && && && && && && && && && && && && && && && && && && && && && && &&&|&&951 B& &&&00:00& &&&

10gen& && && && && && && && && && && && && && && && && && && && && && && && && && && && && & 96/96
0 packages excluded due to repository protections
Error: No matching Packages to list
第二个错误是
[root@localhost ~]# yum info mongo-10gen-server
Loaded plugins: fastestmirror, protectbase
Loading mirror speeds from cached hostfile
* epel: mirrors.
* extras: mirrors.
* updates:
10gen& && && && && && && && && && && && && && && && && && && && && && && &&&|&&951 B& &&&00:00& &&&
Not using downloaded repomd.xml because it is older than what we have:
&&Current& &: Thu Jul 18 04:27:57 2013
&&Downloaded: Thu Jul 18 04:27:16 2013
0 packages excluded due to repository protections
Error: No matching Packages to list
yum的更新原则应该是会将本地的repomod.xml文件的修改日期与yum服务器的更新文件repomd.xml 作比较,然后从其中选择一份最新的文件,当发现yum服务器上的更新文件比本地的文件要旧时,就会报错啦..
解决办法：yum clean all 和 yum check-update
[root@localhost ~]# yum clean all
Loaded plugins: fastestmirror, protectbase

[root@localhost ~]# yum check-update

使用的是oracle linux,在同学的推荐下来看了这个帖子，确实在第二步“yum的更新原则应该是会将本地的repomod.xml文件的修改日期与yum服务器的更新文件repomd.xml 作比较,然后从其中选择一份最新的文件,当发现yum服务器上的更新文件比本地的文件要旧时,就会报错啦..”
