After you deploy vCloud Usage Meter, the appliance generates a self-signed SSL certificate. When you access the vCloud Usage Meter Web interface over HTTPS for the first time, you are prompted to manually trust the self-signed certificate.

You can secure the connection to vCloud Usage Meter by replacing the vCloud Usage Meter self-signed certificate with by using an external or internal Certification Authority (CA) - signed certificate.

When running, all vCloud Usage Meter applications use the same keystore and CA certificate store. The NGINX certificates are updated on OS startup. Unless specifically noted, you can run commands on the vCloud Usage Meter console as usagemeter.

To allow remote interaction with the vCloud Usage Meter console, you can activate SSH or invoke the commands in a vSphere web console.

The vCloud Usage Meter appliance stores the certificates in a Java key store at /opt/vmware/cloudusagemetering/platform/security/keystore.

The CA certificate key store is located at /opt/vmware/cloudusagemetering/platform/security/cacerts.

Note: The certificate CN and Subject Alternative Name (SAN) must match the hostname of the vCloud Usage Meter appliance.

Import an Internal Certificate Authority (CA) - Signed Certificate for a vCloud Usage Meter Appliance with Enabled FIPS Mode

If you want to replace the vCloud Usage Meter certificate with a certificate signed by an internal Certificate Authority (CA), you must first import the CA to the vCloud Usage Meter appliance with enabled FIPS mode.

Prerequisites

  • Verify that you have access to the vCloud Usage Meter console as usagemeter.
  • Verify that FIPS is enabled for the vCloud Usage Meter appliance by navigating to Settings > Security.

Procedure

  1. Log in to the vCloud Usage Meter console as usagemeter and stop all appliance services. 
    cd /opt/vmware/cloudusagemetering
    ./scripts/stop.sh All
    sudo systemctl stop vmware-um-journal.service
    sudo systemctl stop vmware-um-login.service
    sudo systemctl stop vmware-um-schedule.service
  2. Export the environment variables. 
    export $(grep -v '^#' "/opt/vmware/cloudusagemetering/platform/conf/env.properties" | xargs)
  3. Establish a trust between the vCloud Usage Meter appliance with enabled FIPS mode and the certificate that is signed by the internal certificate authority.
    Enter a name that identifies the certificate within the keystore under the alias property in the following command.
    Note: If FIPS mode is deactivated for the vCloud Usage Meter appliance, see Import an Internal Certificate Authority (CA) - Signed Certificate for a vCloud Usage Meter Appliance with Deactivated FIPS Mode. 
    keytool -import -trustcacerts -file filepath-to-the-certificate -alias custom-internal-certificate-authority -keystore /opt/vmware/cloudusagemetering/platform/security/cacerts -storetype BCFKS -providerclass org.bouncycastle.jcajce.provider.BouncyCastleFipsProvider -providerpath /opt/vmware/cloudusagemetering/platform/lib/bc-fips-1.0.2.1.jar -storepass "${TRUST_STORE_PASSWORD}"
  4. Reboot the vCloud Usage Meter appliance with enabled FIPS mode.

Prerequisites

  • Verify that you have access to the vCloud Usage Meter console as usagemeter.
  • Verify that FIPS is deactivated for the vCloud Usage Meter appliance by navigating to Settings > Security.

Procedure

  1. Log in to the vCloud Usage Meter console as usagemeter and stop all appliance services. 
    cd /opt/vmware/cloudusagemetering
    ./scripts/stop.sh All
    sudo systemctl stop vmware-um-journal.service

Install a Certificate Authority (CA) - Signed Certificate for a vCloud Usage Meter Appliance with Enabled FIPS Mode

To establish a secure network connection to the vCloud Usage Meter Web interface, you can install a CA-signed SSL certificate on the vCloud Usage Meter appliance with enabled FIPS mode.

To obtain a CA-signed certificate and private key, you must generate a certificate signing request. The certificate authority uses the request to generate the official certificate.
