CentOS 4 EOL AnnouncementThe 7-year enterprise lifetime of CentOS-4 ends now. CentOS-4 has been copied to the CentOS Vault. The last released tree is available
here.All architectures of CentOS-4 (i386, x86_64, ppc, s390, and s390x) are
impacted. Support for the CentOS-4 Cluster Server and the CentOS-4
Global File Server (csgfs) is also ended.
The CentOS-4.8 and 4.9 trees will be emptied from the CentOS mirrors in
short order.
CentOS-4 will remain available in the CentOS Vault, along with CentOS-2
and CentOS-3, indefinitely. You can use the vault in the same way you
have used the CentOS mirrors in the past, however no updates will be
released for CentOS-4 moving forward.
Accordingly, the CentOS Project strongly recommends that you migrate any
CentOS-4 installs to a newer version of CentOS (either CentOS-5 or
CentOS-6).
