Method 2: Via CLI
1. Your certificate ZIP file will be sent by email. The certificate ZIP is included as an attachment and certificate file is also imbedded in the body of the email.
2. Copy and paste the certificate into a text file (save as commercial.crt) using Vi or Notepad. Place this file in the following directory /opt/zimbra/ssl/zimbra/commercial/
The text file should look like:
3. Open the CAbundle that you received on a ZIP file using a text editor or Vi and save it as (commercial_ca.crt). Place this file in the following directory /opt/zimbra/ssl/zimbra/commercial/
Note: If you are using notepad, then click "Save as" and in the save location window, choose 'save as' type as "ALL files" and give the file name as commercial_ca.crt.
4. Also, rename your private key file as commercial.key and move it to the same directory where we have placed other certificate files /opt/zimbra/ssl/zimbra/commercial/
5. Now since you have all the files in the same directory, we can now enable the certificate. But first, let's Validate the Certificate Chain using the below command,
<em>/opt/zimbra/openssl/bin/openssl verify -CAfile commercial_ca.crt commercial.crt</em>
If successful, youâ€™ll get back a response like <cert name>: OK
6. Finally deploy your certificate using the following command,
/opt/zimbra/bin/zmcertmgr deploycrt comm commercial.crt commercial_ca.crt
7. Restart the Zimbra Services
