This is using zimbra collaboration suite 6.0.6, for SUSE Linux Enterprise server 11.0. In Zimbra admin console, the certificate is going to expire in 10 days. I'm thinking of renew the cert, how to do it? Should I backup first, and how?

The basics:

su - (root)
cp -a /opt/zimbra/conf /opt/zimbra/conf.bak
cp -a /opt/zimbra/ssl /opt/zimbra/ssl.bak
cd /opt/zimbra/bin
./zmcertmgr createcrt -new
./zmcertmgr deploycrt self.
./zmcertmgr viewdeployedcrt
su - zimbra
zmcontrol restart


For other details on length, subject names, or if you wish to re-create the full certificate authority as well please see http://wiki.zimbra.com/wiki/Administration_Console_and_CLI_Certificate_Tools#Single-Node_Self-Signed_Certificate

Hi MCode151,

After executing all the commands as stated by you, how about client side? Do I have to execute any command to renew the cert?

Client side as in end user?

Upon new connection they'll get the new cert (which should happen relatively soon because you restarted) some thick-mail clients if open might prompt you that the cert has changed, other thick-clients & web-browsers save the fingerprint and will notify you when they reopen, or require a close/open, and still others might not say a thing.

In short, there's no 'commands to issue client side'.  It's up to you (depending on your end-user base and their technical abilities/how many might bug you about it) if you want to notify them in advance that you're installing a new certificate, and that they should accept any mail/web client warning prompts.
