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忽然很差使用,使用yum的时候报错以下:
[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 againnode

解决办法:(或者把/etc/yum.repos.d下的文件所有删除,而后将能正常使用yum的同类服务器的这个目录下的文件所有拷贝过来,而后yum clean all 和yum makecache 便可)
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源更改成阿里云的yum源,操做以下:centos

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

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

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

而后执行如下命令:
[root@bastion-IDC yum.repos.d]# rpm -e rpmforge-release --nodeps
-------------------------------------------------------------------------------------------------------------
若是报错:
error: package rpmforge-release is not installedcentos7

解决办法:安装这个源
连接: https://pan.baidu.com/s/11ieAD1F6uNhmCiauK3v8Sw code

提取码: d15c xml


[root@bastion-IDC yum.repos.d]# rpm -ivh rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm
-------------------------------------------------------------------------------------------------------------blog

[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,以提升搜索安装软件的速度
[root@bastion-IDC yum.repos.d]# yum updatev8

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

 

yum源配置方法一(阿里云源)

1) 安装wget

yum install -y wget

2) 备份/etc/yum.repos.d/CentOS-Base.repo文件

cd /etc/yum.repos.d/
mv CentOS-Base.repo CentOS-Base.repo.back

3) 下载阿里云的Centos-6.repo文件

wget -O CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

4) 从新加载yum

yum clean all
yum makecache
