How to install SSL in Zimbra with Certificate and CA-bundle

There are 3 things you need:

1. Private key
2. Certificate
3. Ca-bundle

First, switch to the user zimbra:

su - zimbra

Let’s except your files are located here:

Private Key: /tmp/private.key
Certificate: /tmp/your.domain.com.crt
Ca-Bundle: /tmp/your.domain.com.ca-bundle

Now, copy your private key file to the following location:

cp /tmp/private.key /opt/zimbra/ssl/zimbra/commercial/commercial.key

Now, first, verify 3 things to make sure, they are correct:

/opt/zimbra/bin/zmcertmgr verifycrt comm /opt/zimbra/ssl/zimbra/commercial/commercial.key /tmp/your.domain.com.crt /tmp/your.domain.com.ca-bundle

If it, says ok, now you may deploy the certificate like the following:

/opt/zimbra/bin/zmcertmgr deploycrt comm /tmp/your.domain.com.crt /tmp/your.domain.com.ca-bundle

Once done, now, exit from the user zimbra and restart zimbra:

exit
service zimbra restart

Your SSL should work now.
