For URL-based patching, by default the vCenter Server appliance is configured to use the default VMware repository URL that is preset for the build profile of the appliance. You can configure a custom repository URL as the current source of patches for your environment's requirements.

By default the current repository for URL-based patching is the default VMware repository URL.

If vCenter Server is not connected to the Internet or if your security policy requires it, you can build and configure a custom repository. The custom patching repository runs on a local Web server within your data center and replicates the data from the default repository. Optionally, you can set up an authentication policy for accessing the Web server that hosts the custom patching repository.


Log in to the vCenter Server Management Interface as root.
