The process described in this page will let an administrator replace the default DPOD Web Console and Admin Console certificate with one signed by the organization.

Prerequisites

...

Access to the DPOD appliance

...

system encrypts the communication between end-users and the Web & Admin Consoles with self-signed certificates generated during the installation.

Use the following procedure to replace these certificates:

1. Make sure you have the new certificate and key files

...

Process

1.  Log provided in .pem format.

2. In a Cell Environment, perform all the steps on the cell manager only.

3. Log in to DPOD's appliance server using SSH.

4. Copy the new certificate and key files either to the current certificate directory on the DPOD appliance or to any other directory of your choice.
   The current certificate directory is /etc/httpd/conf/certs.

5. Generate a new Diffie-Hellman (DH) Group for a more secured TLS session:

   Code Block
   language bash
   openssl dhparam -out /etc/httpd/conf/certs/dhparams.pem 2048

   Append the new DH group parameters file to the new certificate

   Code Block
   language bash
   cat /etc/httpd/conf/certs/dhparams.pem >> /etc/httpd/conf/certs/New_DPOD_Cer.cer

   See an example of the certificate file below:

   Code Block

6. Open the web server configuration file for editing:

   Code Block
   language bash
   vi /etc/httpd/conf/httpd.conf

7. Update the SSL Certificate lines:

   Code Block
   language bash
   SSLCertificateFile "the new certificate file path" SSLCertificateKeyFile "the new key file path"

   SSLCertificateKeyFile needs to point to a key of a "PEM" format. 

   SSLCertificateFile needs to point to a certificate of a "PEM" format.
   Note: The certificate / key cannot be stored in a keystore (JKS, PKCS).

8. Restart the web server:

   Code Block
   language bash
   service httpd restart
