CentOS 7.0 yum install 错误http://vault.centos.org/centos/7/os/Source/repodata/repomd.xml: [Errno 14]

执行yum install vconfig时老是报错：

http://vault.centos.org/centos/7/os/Source/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not
Found

经过分析：

原因是标准的CentOS 7.0 Build1406里面很多的仓库已经被CentOS移除了，转到CentOS 7.1 Build1503和CentOS7.2 Build1503了。

因此需要手工更改仓库文件/etc/yum.d.repo/CentOS-Sources.repo，

更改之前，先备份下

#cp CentOS-Sources.repo CentOS-Sources.repo.bak

然后开始编辑CentOS-Sources.repo文件。

将文件中的“$releasever”全部替换成“7.2.1511”或者“7.1.1503”。

更改完成后执行
