CentOS was a community-supported enterprise Linux distribution built from Red Hat Enterprise Linux sources and widely used on servers and infrastructure.
It became popular for providing enterprise-style stability, broad package availability, and long-lived deployments without commercial licensing costs.
Its legacy now continues through related projects and downstream enterprise Linux ecosystems.

Once you have downloaded an image, be sure to verify it for both security and integrity.
By calculating the image’s checksum on your own computer and comparing it to the original checksum, you can verify the image has not been tampered with or corrupted. When the project provides signed checksums, verify their signature using the project's published signing key and instructions.
Download the checksum file for your exact CentOS Linux image from the project's release source.
If signed checksums are provided, obtain the project's signing key and confirm its fingerprint using the project's documentation.
Follow the project's verification instructions to validate the checksum file's signature before trusting its contents.
For a SHA-256 checksum file supported by sha256sum, run the following in the directory containing your downloaded image. Replace CHECKSUM_FILE with the actual checksum filename.
sha256sum -c CHECKSUM_FILE
Continue only when verification succeeds. If a checksum or signature fails, download the image again and verify it before installing.
