There are several steps involved in managing SSL certificates in vSphere. Here is a quick guide:
1. Obtain the SSL/TLS certificate from a trusted certificate authority (CA). This certificate should be in the PEM format.
1. Log in to the vCenter Server using the vSphere Web Client.
1. Navigate to the “Administration” tab on the top of the screen.
1. Open the “Certificate Management” section and select “SSL Certificate”.
1. Choose the “Replace Certificate” option.
1. Select the “Use Custom Certificate” option and browse the PEM file containing the SSL/TLS certificate.
1. If you are replacing a CA-signed certificate, you can upload the corresponding root and intermediate certificates.
1. Verify that the certificate details are correct and click “Finish” to complete the process.
1. After replacing the SSL/TLS certificate, all vSphere components that use SSL will need to be restarted. This includes the vSphere Web Client, vCenter Server, and ESXi host services.
1. To ensure that the new certificate is properly verified, validate it using SSL server testing tools such as SSL Labs.
By following these steps, you can successfully manage SSL certificates in vSphere.
