Download and Install the vCenter Server Certificate

You can download the vCenter Server root certificate by using a Web browser and add it to the trusted certificates on the machine where you plan to run ESXCLI commands.

1. Enter the URL of the vCenter Server system into a Web browser.
2. Click the Download trusted root CA certificates link.
3. Verify that the extension of the downloaded file is .zip.
   The file is a ZIP file of all certificates in the TRUSTED_ROOTS store.
4. Extract the ZIP file.
   A certificates folder is extracted. The folder includes files with the extension .0, .1, and so on, which are certificates, and files with the extension .r0, .r1, and so on which are CRL files associated with the certificates.
5. Add the trusted root certificates to the list of trusted roots.
   The process differs depending on the platform that you are on.
