 +====== CentOS 5 "cannot find a valid baseurl for repo" Error Fix ======
  
 +When trying to update or install packages on older CentOS 5 systems, you may run into the following error.
 +
 +<code>
 +root@server1 [~]# yum update -y
 +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/base/mirrorlist.txt
 +Error: Cannot find a valid baseurl for repo: base
 +</code>
 +
 +This is commonly caused by attempting to use deprecated repositories. The update repositories were moved to the CentOS vault when the operating reached it's end-of-life.
 +
 +In order to continue using the operating system packages, you will need to update your repository entries to point to the vault.
 +
 +Using your favorite text editor, open **/etc/yum.repos.d/CentOS-Base.repo**
 +
 +Look for the following:
 +
 +<code>
 +[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/
 +gpgcheck=1
 +gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5
 +</code>
 +
 +Comment out the mirror list, and uncomment the baseurl. So it should look like the following:
 +
 +<code>
 +#mirrorlist=
 +baseurl=
 +</code>
 +
 +Next, you will need to put in the URL for the vault repository.
 +
 +for 32-bit systems, use:
 +http://vault.centos.org/5.11/os/i386/
 +
 +for 64-bit systems, use:
 +http://vault.centos.org/5.11/os/x86_64/
 +
 +<note>For each repository, you will need to replace /os/ with what repository subdirectory you need. For example on a 64-bit system, for updates, your URL will look like **http://vault.centos.org/5.11/updates/x86_64/** and for extras it will look like **http://vault.centos.org/5.11/extras/x86_64/** Always check the old url first to make sure you have right path. You can also check **http://vault.centos.org** to see all available repositories.
 +</note>
 +
 +Once you have added this, run the following to clean your yum cache:
 +
 +<code>
 +yum clean all
 +</code>
 +
 +Then update yum to start using the new repositories:
 +
 +<code>
 +yum update
 +</code>
 +
 +\\
