n
If necessary, enable the ESXi Shell or enable SSH traffic from the vSphere Web Client.
n
All file transfers and other communications occur over a secure HTTPS session. The user who is
used to authenticate the session must have the privilege Host.Config.AdvancedConfig on the host.
Procedure
1 Back up the existing certificates.
2 Generate a certificate request following the instructions from the certificate authority.
See Requirements for ESXi Certificate Signing Requests.
3 When you have the certificate, use the vifs command to upload the certificate to the appropriate
location on the host from an SSH connection to the host.
vifs --server hostname --username username --put rui.crt /host/ssl_cert
vifs --server hostname --username username --put rui.key /host/ssl_key
4 Restart the host.
What to do next
Update the vCenter Server TRUSTED_ROOTS store. See Update the vCenter Server
TRUSTED_ROOTS Store (Custom Certificates).
Replace a Default Certiļ¬cate Using HTTPS PUT
You can use third-party applications to upload certificates and key. Applications that support HTTPS PUT
operations work with the HTTPS interface that is included with ESXi.
Prerequisites
n
If you want to use third-party CA-signed certificates, generate the certificate request, send it to the
certificate authority, and store the certificates on each ESXi host.
n
If necessary, enable the ESXi Shell or enable SSH traffic from the vSphere Web Client.
n
All file transfers and other communications occur over a secure HTTPS session. The user who is
used to authenticate the session must have the privilege Host.Config.AdvancedConfig on the host.
