RHEL5.x配置YUM 从centos5源更新

卸载rhel自带yum

rpm -aq|grep yum|xargs rpm -e --nodeps

安装Centos yum后请按照以下步骤修改CenOS-Base.repo

cd /etc/yum.repos.d
mv CentOS-Base.repo CentOS-Base.repo.save
wget http://centos.ustc.edu.cn/CentOS-Base.repo -O /etc/yum.repos.d/CentOS-Base.repo
 

Step 1：修改/etc/yum.repos.d/CentOS- Base.repo为:

# 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.
