實戰操作:

切換到目錄 /etc/yum.repos.d/[root@oel63 ~]# cd /etc/yum.repos.d/

獲取配置文件并進行相應修改[root@oel63 yum.repos.d]# wget http://public-yum.oracle.com/public-yum-ol6.repo--2014-05-16 14:41:51--  http://public-yum.oracle.com/public-yum-ol6.repoResolving public-yum.oracle.com... 184.51.198.32, 184.51.198.8, 184.51.198.65Connecting to public-yum.oracle.com|184.51.198.32|:80... connected.HTTP request sent, awaiting response... 200 OKLength: 4233 (4.1K) [text/plain]Saving to: “public-yum-ol6.repo”
