本地安装的centos5.5，使用网易163 yum更新源的时候，提示404错误：[Errno 14] HTTP Error 404: Not Found
直接相应的地址，发现网易镜像网站目录里已经不存在此页，真正存储这些文件的地址是http://mirrors.163.com/centos/5/
于是根据情况修改CentOS5-Base-163如下：
# 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. # # [base] name=CentOS-5 - Base - 163.com baseurl=http://mirrors.163.com/centos/5/os/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=5&arch=$basearch&repo=os gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5 #released updates [updates] name=CentOS-5 - Updates - 163.com baseurl=http://mirrors.163.com/centos/5/updates/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=5&arch=$basearch&repo=updates gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5 #packages used/produced in the build but not released [addons] name=CentOS-5 - Addons - 163.com baseurl=http://mirrors.163.com/centos/5/addons/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=5&arch=$basearch&repo=addons gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5 #additional packages that may be useful [extras] name=CentOS-5 - Extras - 163.com baseurl=http://mirrors.163.com/centos/5/extras/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=5&arch=$basearch&repo=extras gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-5 - Plus - 163.com baseurl=http://mirrors.163.com/centos/5/centosplus/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=5&arch=$basearch&repo=centosplus gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5 #contrib - packages by Centos Users [contrib] name=CentOS-5 - Contrib - 163.com baseurl=http://mirrors.163.com/centos/5/contrib/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=5&arch=$basearch&repo=contrib gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
