＜追記＞
CentOS4の時の記事でしたが、CentOS5が切れても使う事になるとおもわなかった(笑)
CentOS4は最終が「4.9」、CentOS5は最終が「5.11」です。
手順は同じで、mirrorlistをコメントアウトして、「vault.centos.org」にしたbaseurlをに置き換えればOKです。
古いOSネタですが、CentOS4のリポジトリはもう無くなってるので「vault.centos.org」にいっちゃったのを指定してアップデートする方法
どっかにメモったったはずなんだけど、どっかいったのでここにメモしておく(^^;
変更ファイル
→リポジトリが記述されたファイル
/etc/yum.repos.d/CentOS-Base.repo
変更例
→mirrorlistはコメントにして、baseurlを「vault.centos.org」のフォルダ指定へ変更する
# CentOS-Base.repo # # This file uses a new mirrorlist system developed by the CentOS Team. # 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-$releasever - Base #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os #baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/ baseurl=http://vault.centos.org/4.9/os/$basearch/ gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos4 priority=1 protect=1 #released updates [update] name=CentOS-$releasever - Updates #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates #baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/ baseurl=http://vault.centos.org/4.9/updates/$basearch/ gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos4 priority=1 protect=1 #packages used/produced in the build but not released [addons] name=CentOS-$releasever - Addons #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=addons #baseurl=http://mirror.centos.org/centos/$releasever/addons/$basearch/ baseurl=http://vault.centos.org/4.9/addons/$basearch/ gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos4 priority=1 protect=1 #additional packages that may be useful [extras] name=CentOS-$releasever - Extras #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras #baseurl=http://mirror.centos.org/centos/$releasever/extras/$basearch/ baseurl=http://vault.centos.org/4.9/extras/$basearch/ gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos4 priority=1 protect=1 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$releasever - Plus #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus #baseurl=http://mirror.centos.org/centos/$releasever/centosplus/$basearch/ baseurl=http://vault.centos.org/4.9/centosplus/$basearch/ gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos4 priority=2 protect=1 #contrib - packages by Centos Users [contrib] name=CentOS-$releasever - Contrib #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=contrib #baseurl=http://mirror.centos.org/centos/$releasever/contrib/$basearch/ baseurl=http://vault.centos.org/4.9/contrib/$basearch/ gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos4 priority=2 protect=1
