  • 1.  Renew Self-Signed Certificate

    Posted Mar 25, 2024 12:21 PM

    Hi,

    Running vSphere 8.02 with 2 esxi 7.0 update 3 hosts. Just got a "Certificate Alert" in vsphere. It's due to expire in a couple weeks. The STS Certificate, VMWare Cert Authority, and Root Cert are all good for another six years.

    I'm using self-signed certificates. Is it really as simple as going to VSphere > Administration > Certificates > Certificate Management > Machine SSL Certificate > Actions > Renew? What risks are there to my servers stopping functioning or me not being able to log in to vSphere? Anything else I need to watch for? Compared to most of you I have a tiny and (I think) pretty simple setup.

    Thanks,

    Jeff

    You are correct on the renewal.  You will need to reconnect the host to vCenter in order for the certificate hash to be recognized.  It should not halt any running VMs.
