CentOS 7 Iso File SHA-256 Hashes

I downloaded CentOS-7-x86_64-Everything.iso (8,233,418,752 bytes) by clicking on the ‘Everything’ link in the ‘Rolling’ line on https://wiki.CentOS.org/Download (supposedly the 1611 build).

But when I look in the sha256sum.txt file from https://buildlogs.CentOS.org/rolling/7/isos/x86_64/ (where Chrome says that iso came from), there is no SHA hash for a file of that name.

The reason I wanted to check it is because it’s a different size than another one I found on my hard drive while looking through the Downloads history in Chrome.

The other file I found was CentOS-7-x86_64-Everything-1611.iso
(8,280,604,672 bytes), which returns a hash of af4969ebbdc479d330de97c5bfbb37eedc64c369f009cb15a97f9553ba441c88 and that matches the value given in the sha256sum.txt file for the file of that name.

So, my question is tri-fold. what’s the SHA-256 hash supposed to be for the file given when clicking the ‘Everything’ link on CentOS.org. then, why is the ‘official’ download link sending a file that’s not listed in the hash results. and finally, why is the file sent thusly, different from another
‘everything’ iso allegedly from the same build?

Thanks.

  • The CentOS-7-x86_64-Everything.iso (without a version) is a symlink to the ‘lastest’ Everything iso. If you look at the sha256sum file, the last Everything file listed will be the version you use.

    Currently that would be:

    CentOS-7-x86_64-Everything-1702-01.iso

    Good info; thanks again… but shouldn’t the date code in the column labeled “Minor release” now say (1702) instead of (1611) ?
