    We have a couple of very old DNS-only VPSs that are running CentOS 5. These need to be upgraded, probably to CentOS 7 to futureproof themselves.

    They only run BIND. They only have 512MB of RAM, but continue to hum along just fine.

    Can DNS-ONLY be installed on a CentOS 7 VPS with just 512MB of RAM?

    I'm just trying to get a general idea of how to plan to upgrade these servers.

    Hello,

    512MB should be suitable if you are only using it to serve DNS Zones. You can use the "--force" flag when beginning the installation to bypass the memory requirements:

    Code:
    sh latest-dnsonly --force
    Let us know if you have any additional questions.

    Thanks!
