CentOS5.xでyum installできなくなってしまった場合の対応メモ

諸事情で、CentOS5のサーバーをメンテしないといけない場面がまだあったりします・・・

そもそもこの状況をなんとかしないといけないのですが・・・まあそれは置いといて

ntp入れるよ！

$ sudo yum -y install ntp
Loaded plugins: fastestmirror
Determining fastest mirrors
YumRepo Error: All mirror URLs are not using ftp, http[s] or file.
 Eg. Invalid release/
removing mirrorlist with no valid mirrors: /var/cache/yum/addons/mirrorlist.txt
Error: Cannot find a valid baseurl for repo: addons

もうリポジトリが提供されてないです

$ cat /etc/redhat-release
CentOS release 5.4 (Final)

5.4用のリポジトリを再設定します

/etc/yum.repos.d/centos5.4.vault.repo

[centos5.4.vault]
name=centos5.4.vault
baseurl=http://vault.centos.org/5.4/updates/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5
enabled=0

/etc/yum.repos.d/CentOS-Base.repoはenabled=0を追記するなりコメントアウトするなりバックアップ取って消すなりします

$ sudo yum install ntp --enablerepo=centos5.4.vault
