以下為原文：

CentOS 5 has reached end of life upstream. 

As there will be no more fixes for RHEL 5 released public upstream by Redhat then there will be no more updates for CentOS 5 either. You are encouraged to migrate any remaining systems to CentOS 7 or to CentOS 6 (which itself enters Production Phase 3 upstream in May 2017 with End of Life coming in 2020).

Expect the current CentOS 5 mirror content to migrate to vault.centos.org in the near future.

This notice was originally posted when CentOS 5 had one year of supported life left. It now has 6 1 month 1 week. You are encouraged to put your migration plans into action now if you haven't already done so. CentOS 6 goes EOL in 2020, CentOS 7 in 2024.
