yum源外網配置及問題解決

安裝外網的yum步驟

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

儲存退出

然後yum clean all（清空yum）,yum makecache

但是在yum makecache時出現如下錯誤：

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'"

于是就各種找答案，各種嘗試，最後發現是DNS的問題，

vi /etc/resolv.conf檔案添加如下

nameserver 8.8.8.8(你自己的DNS伺服器)

然後重新yum makecache即可成功
