The vRealize Automation appliance uses lighttpd to run its own management site. You can replace the SSL certificate of the management site service if your certificate expires or if you are using a self-signed certificate and your company security policy requires you to use its SSL certificates. You secure the management site service on port 5480.

You can choose to install a new certificate or reuse the certificate used by the vCloud Automation Center service on port 443.

When you request a new certificate to update another CA-issued certificate, it is a best practice to reuse the Common Name from the existing certificate.


  • New certificates must be in PEM format and the private key cannot be encrypted. By default, the vRealize Automation appliance management site SSL certificate and private key are stored in a PEM file located at /opt/vmware/etc/lighttpd/server.pem.

    See Extracting Certificates and Private Keys if you require information about exporting a certificate and private key from a Java keystore to a PEM file.


  1. Log in by using the appliance console or SSH.
  2. Back up your current certificate file.
    cp /opt/vmware/etc/lighttpd/server.pem /opt/vmware/etc/lighttpd/server.pem-bak
  3. Copy the new certificate to your appliance by replacing the content of the file /opt/vmware/etc/lighttpd/server.pem with the new certificate information.
  4. Run the following command to restart the lighttpd server.

    service vami-lighttp restart

  5. Log in to the management console and validate that the certificate is replaced. You might need to restart your browser.


The new vRealize Automation appliance management site certificate is installed.

What to do next

Update all management agents to recognize the new certificate.

For distributed deployments, you can update management agents manually or automatically. For minimal installations, you must update agents manually.
