SSL Certificate

Jump to solution

Hello,

I would like to install a valid certificate on our VirtualCenter Server (at the moment we have an expired, unrecognised certificate) in order to use the VMware Virtual Infrastructure Web Access.

I read this article: and it states that in order to change the certificate I have to stop every VM in every server (we have 14 blades with approx 80 machines running). Is this absolutely necessary?

All I want to do is to install a certificate exclusively for web interface access use, I don't want to change the certificate on the ESX machine too. Is that absolutely necessary?

Thanks,

Roberto.

The following will happend when changing the SSL certs on the vCenter.

- The Service cant connect to the Database anymore because the password crypt isnt the same any more. To fix that you have to run "vxpd -p" on the command shell

- IIRC a similar problem exits with if you use customizing templates

There are no effects with the ESX. If your SSL Cert is based on a self create RootCA you have to import this into your Windows Cert Store (trusted RootCAs).

Hello,

Moved to vCenter server forum.

Yes as they all use the same certificate.

No its not necessary. I used my own selfsigned certs on every vcenter/esx and i cant remember that i have shutdown a single VM. All these clusters starts with vmware default certs and i change them after the cluster/installation went into production.

Texiwill, Altix,

first of all thanks for answering. What could happen if I replace the certificates in the c:\docu & sets\all users\application data\vmware\ssl of the "VMware Center" and not on the ESXs:

- would the ESX machines be affected (in any way)?

- Am I still gonna get the certificate error opening the web console with IE?

Thanks again,

Bye,

Roberto.
