I know it sounds like a very simple process.It is usually told that you can open the powershell application and access it with the “Connect-VIserver” command sets.
This information is correct but incomplete because the need to required install the powershell module.
Install-Module -Name VMware.PowerCLI
If you have installed the module, you can now connect to VMware vCenter via Powershell.
Connect-VIserver -Server vCenter -Port 443
If you get an error like the one below while connecting, you can use the command below to ignore the warning.
Error: Invalid server certificate. Use Set-PowerCLIConfiguration to set the value for the InvalidCertificateAction option to Prompt if you’d like to connect once or to add a permanent exception for this server. Additional Information: Could not establish trust relationship for the SSL/TLS secure channel with authority
Set-PowerCLIConfiguration -InvalidCertificateAction Ignore -Confirm:$false
Now you can connect
Have a nice day !
