首先是備份/etc/yum.repos.d/CentOS-Base.repo 文件,
然后把下載的和你系統(tǒng)相對應(yīng)的CentOS-Base.repo 替換 /etc/yum.repos.d/CentOS-Base.repo 文件
然后#yum check-update
#mirrors-shlug-org.repo
#
# rpm --import http://mirrors.shlug.org/centos/RPM-GPG-KEY-CentOS-5
#
# This file uses a new mirrorlist system developed by Lance Davis for CentOS.
# 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.
