This is the notification of the End of Life (EOL) for CentOS 4.
The 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).
================================================
If you have workloads that you can not move to a newer version CentOS, Red Hat, Inc. offers an optional support extension called the "Extended Life-cycle Support (ELS) Add-On Subscription" for their Red Hat Enterprise Linux (RHEL) 4 product. The ELS Subscription provides up to three additional years of limited Software Maintenance (Production 3 Phase) for RHEL 4 with unlimited technical support, critical Security Advisories (RHSAs) and selected Urgent Priority Bug Advisories (RHBAs). This service from Red Hat, Inc. would require both a RHEL 4 subscription and an ELS subscription.
Note: The CentOS Project is not affiliated with Red Hat, Inc. CentOS-4 is not, nor does it contain, Red Hat Enterprise Linux 4. However, CentOS-4 is built from publicly available sources released by Red Hat, Inc. Because of these common source files, work loads running on CentOS-4 should be able to be moved to Red Hat Enterprise Linux 4 and allow you to use that platform with ELS for an additional 3 years if you need that service.
Please see this link for more details about Red Hat ELS:
