After you receive the custom certificates, you can replace each machine certificate.
About this task
Each machine must have a machine SSL certificate for secure communication with other services. In a multi-node deployment, you must run the Machine SSL certificate generation commands on each node. Use the --server parameter to point to the Platform Services Controller from a vCenter Server with external Platform Services Controller.
You must have the following information before you can start replacing the certificates:
Password for email@example.com.
Valid Machine SSL custom certificate (.crt file).
Valid Machine SSL custom key (.key file).
Valid custom certificate for Root (.crt file).
If you are running the command on a vCenter Server with external Platform Services Controller in a multi-node deployment, IP address of the Platform Services Controller.
You must have received a certificate for each machine from your third-party or enterprise Certificate Authority.
Key size: 2048 bits or more (PEM encoded)
x509 version 3
SubjectAltName must contain DNS Name=<machine_FQDN>
Contains the following Key Usages: Digital Signature, Non Repudiation, Key Encipherment
- Stop all services and start the services that handle certificate creation, propagation, and storage.
The service names differ on Windows and the vCenter Server Appliance.
service-control --stop --all service-control --start VMWareAfdService service-control --start VMWareDirectoryService service-control --start VMWareCertificateService
vCenter Server Appliance
service-control --stop --all service-control --start vmafdd service-control --start vmdird service-control --start vmcad
- Log in to each node and add the new machine certificates that you received from the CA to VECS.
All machines need the new certificate in the local certificate store to communicate over SSL.
vecs-cli entry delete --store MACHINE_SSL_CERT --alias __MACHINE_CERT vecs-cli entry create --store MACHINE_SSL_CERT --alias __MACHINE_CERT --cert <cert-file-path> --key <key-file-path>
- Restart all services.
service-control --start --all
Replace Machine SSL Certificates with Custom Certificates
You can replace the machine SSL certificate on each node the same way.
First, delete the existing certificate in VECS.
"C:\Program Files\VMware\vCenter Server\vmafdd\"vecs-cli entry delete --store MACHINE_SSL_CERT --alias __MACHINE_CERT
Next, add the replacement certificate.
"C:\Program Files\VMware\vCenter Server\vmafdd\"vecs-cli entry create --store MACHINE_SSL_CERT --alias __MACHINE_CERT --cert E:\custom-certs\ms-ca\signed-ssl\custom-w1-vim-cat-dhcp-094.eng.vmware.com.crt --key E:\custom-certs\ms-ca\signed-ssl\custom-x3-vim-cat-dhcp-1128.vmware.com.priv
What to do next
You can also replace the certificates for your ESXi hosts. See the vSphere Security publication.
After replacing the root certificate in a multi-node deployment, you must restart services on all vCenter Server with external Platform Services Controller nodes.
