配置centos5.8 本地源

由于项目需要安装centos5.8，很古老。所有的在线yum源都down了

只能指定本地源。

wget -0 /data/ http://vault.centos.org/5.8/isos/x86_64/CentOS-5.8-x86_64-bin-DVD-1of2.iso  

mount -o loop CentOS-5.8-x86_64-bin-DVD-1of2.iso /mnt/  

vi /etc/yum.repos.d/CentOS-Base.repo 

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
