Implementing CA signed SSL certificates with vSphere 5.x (2034833)

Purpose

This article provides information on manually configuring Certificate Authority (CA) signed SSL certificates in a vSphere 5.1 or vSphere 5.5 environment. VMware has released a tool to automate much of the described process below. Please see Deploying and using the SSL Certificate Automation Tool 1.0.x (2041600) before following the steps in the article.
In the case that you are unable to use the tool this article helps you eliminate common causes for problems during certificate implementation, including configuration steps and details, and helps avoid common misconfigurations in the implementation of custom certificates in your environment.
Note: This article is specifically for vSphere 5.1 and vSphere 5.5. If you are using vSphere 5.0, see Implementing CA signed SSL certificates with vSphere 5.0 (2015383).

Resolution

Configuring CA signed certificates is a challenge with vSphere as with any complex enterprise environment. Securing an environment is a requirement in many large organizations. You need either public certificates (such as Verisign or Globaltrust), Microsoft CA certificates, or OpenSSL CA certificates to ensure a secure communication.
This article provides steps to allow configuration of these certificates on vSphere components in an environment. The article also assumes that all components are installed and running already with self-signed certificates.
Please validate each step below. Each step provides instructions or a link to a document that provides information on configuring the certificates in your environment.
  1. Create a new Certificate Authority template for certificate generation. For more information, see Creating a Microsoft Certificate Authority Template for SSL certificate creation in vSphere 5.x (2062108).
  2. Generate certificate requests and certificates for each of the vCenter Server components. For more information, see:
  3. Replace the vSphere Update Manager Certificates. For more information, see Configuring CA signed SSL certificates for VMware Update Manager in vSphere 5.1 and 5.5 (2037581).

  4. Replace ESXi 5.x host certificates. For more information, see Configuring CA signed SSL certificates with ESXi 5.x hosts (2015499).
