yum源外网配置及问题解决

安装外网的yum步骤

cd /etc/yum.repos.d/

touch my.repo

vi /etc/yum.repos.d/my.repo 

[base]

name=centos6.3

baseurl=http://mirrors.163.com/centos/$releasever/os/$basearch

gpgecheck=0

enable=1

gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6

保存退出

然后yum clean all（清空yum）,yum makecache

但是在yum makecache时出现如下错误：

Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os error was

14: PYCURL ERROR 6 - "Couldn't resolve host 'mirrorlist.centos.org'"

于是就各种找答案，各种尝试，最后发现是DNS的问题，

vi /etc/resolv.conf文件添加如下

nameserver 8.8.8.8(你自己的DNS服务器)

然后重新yum makecache即可成功
