This article discusses the discontinuation of CentOS and its replacement by CentOS Stream. It details how to find information, downloads, and verify the integrity of CentOS Stream ISOs, now primarily hosted on the Red Hat website. Community support
Finding the CentOS Official Website
The official CentOS website, unfortunately, no longer exists in its original form. CentOS was officially discontinued in December 2020, with CentOS Stream taking its place as the upstream development branch for Red Hat Enterprise Linux (RHEL). Therefore, there isn't a single "official" CentOS website in the same way there once was. However, you can find information related to CentOS and its successor, CentOS Stream, through various channels. The primary source of information is now the Red Hat website, as CentOS Stream is closely tied to RHEL. You can find relevant information by searching for "CentOS Stream" on the Red Hat website. While you won't find a dedicated CentOS page, you'll find information regarding the Stream's downloads, documentation, and community resources.
CentOS Download Options (Historically and Currently)
Historically, the official CentOS website offered various download options, including different versions (e.g., CentOS 7, CentOS 8), architectures (e.g., x86_64, ARM), and installation media types (e.g., DVD ISO, minimal ISO). Users could choose the option best suited to their hardware and needs.
Currently, since CentOS is no longer actively developed as a separate distribution, you'll find downloads for CentOS Stream on the Red Hat website. The download options available for CentOS Stream will likely mirror the structure of RHEL downloads, offering different versions, architectures, and installation media types. You should expect to find options for various architectures and ISO types, perhaps including cloud images and other specialized formats. Always check the Red Hat website for the most up-to-date and accurate download options for CentOS Stream.
Verifying CentOS ISO Integrity (Historically and Currently)
Historically, verifying the authenticity and integrity of a CentOS ISO image involved checking the digital signature and comparing checksums. CentOS provided checksums (MD5, SHA1, SHA256) for each ISO image on its download page. Users could download these checksums separately and use a checksum utility (like md5sum or sha256sum in Linux) to verify that the downloaded ISO matched the expected checksums. This process ensured that the downloaded ISO hadn't been tampered with during the download process. Furthermore, verifying the digital signature, if provided, ensured the ISO originated from the official CentOS servers.
For CentOS Stream, the verification process is similar. Red Hat will likely provide checksums (MD5, SHA256, etc.) for each ISO image on their download page. You should always download the checksum file and use a checksum utility to compare it to the checksum of your downloaded ISO image. While digital signatures may not always be prominently featured, it's important to download from the official Red Hat website to minimize the risk of downloading a corrupted or malicious ISO. Trusting the official source is paramount.
Finding CentOS Documentation and Community Support
Historically, the official CentOS website provided extensive documentation, including installation guides, administration manuals, and troubleshooting tips. It also linked to community forums and mailing lists where users could seek help and share knowledge.
For CentOS Stream, documentation and community support are primarily found through Red Hat resources. Red Hat's website offers comprehensive documentation for RHEL, which is closely related to CentOS Stream. While CentOS-specific documentation might be less readily available, the RHEL documentation will provide substantial guidance. Community support is usually available through Red Hat's forums and other community channels dedicated to RHEL. You might also find some community support in forums dedicated to Linux distributions in general. Remember to clearly specify that you are working with CentOS Stream when seeking assistance.
