CentOS系统yum源使用报错:Error: Cannot retrieve repository metadata (repomd.xml) for repository: rpmforge.

 

服务器上的yum突然不好使用,使用yum的时候报错如下:
[root@bastion-IDC src]# yum list
......
Could not retrieve mirrorlist http://mirrorlist.repoforge.org/el6/mirrors-rpmforge error was
14: PYCURL ERROR 7 - "couldn't connect to host"
http://apt.sw.be/redhat/el6/en/x86_64/rpmforge/repodata/repomd.xml: [Errno 14] 
PYCURL ERROR 7 - "couldn't connect to host"
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository: rpmforge. 
Please verify its path and try again

解决办法:(或者把/etc/yum.repos.d下的文件全部删除,然后将能正常使用yum的同类服务器的这个目录下的文件全部拷贝过来,然后yum clean all 和yum makecache 即可)
下载新的CentOS-Base.repo 到/etc/yum.repos.d/
[root@bastion-IDC src]# cd /etc/yum.repos.d/
其实就是将yum源更改为阿里云的yum源,操作如下:

1)centos5.*的下载连接:
[root@bastion-IDC yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo

2)centos6.*的下载连接:
[root@bastion-IDC yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

3)centos7.*的下载连接:
[root@bastion-IDC yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

然后执行以下命令:
[root@bastion-IDC yum.repos.d]# rpm -e rpmforge-release --nodeps
-------------------------------------------------------------------------------------------------------------
如果报错:
error: package rpmforge-release is not installed

解决办法:安装这个源

提取密码:erte
[root@bastion-IDC yum.repos.d]# rpm -ivh rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm
-------------------------------------------------------------------------------------------------------------

[root@bastion-IDC yum.repos.d]# yum clean all 
[root@bastion-IDC yum.repos.d]# yum makecache                                   //将服务器上的软件包信息缓存到本地,以提高搜索安装软件的速度
[root@bastion-IDC yum.repos.d]# yum update

最后再次使用yum就ok了
[root@bastion-IDC yum.repos.d]# yum list
