VMWare Virtual Center ESX Expired SSL Certificate
We just upgraded our ESX farm to VC 2.5 ESX 3.5. It was on an older 2.x version of Virtual Center. The ESX hosts were 3.0.2.
We then realized our SSL Certificate (The VMWare provided, self signed one) had expired a few days prior. Our upgrade to Virtual Center 2.5 and ESX 3.5 did not replace the expired certificate.
We looked into the possibility of installing our Go Daddy wildcard SSL certificate, which requires a process of conversion and it didn’t seem worth the hassle to us. See the links below for more on that.
We were able to rename c:\Documents and Settings\All Users\Application Data\VMware\VMware VirtualCenter\SSL\rui.crt to rui.crt.old and then go to Add/Remove programs and reinstall Virtual Center Server with the Repair option. This installed the new certificate for us.
At this point, all the hosts were disconnected, but right clicking and choosing ‘reconnect’ brought them all right back into VC.
The certificate is now valid for two years.
