Accident happen when server was forced to shutdown due to electrical problem. When the server goes up nothing email server still down. I try to start the service manually.

$ zmcontrol start
Host mail.yourdomain.com
Unable to determine enabled services from ldap.
Unable to determine enabled services. Cache is out of date or doesn’t exist.

Further investigation tell me about certificate expiration, I must renew it.

Here the steps :

# su – zimbra
$ /opt/zimbra/bin/zmcertmgr createca -new
/opt/zimbra/bin/zmcertmgr must be run as user root
$ exit
logout

Hohoho, the command must run by root.

Begin by generating a new Certificate Authority (CA).

# /opt/zimbra/bin/zmcertmgr createca -new

** Creating /opt/zimbra/ssl/zimbra/ca/zmssl.cnf…done
** Creating CA private key /opt/zimbra/ssl/zimbra/ca/ca.key…done.
** Creating CA cert /opt/zimbra/ssl/zimbra/ca/ca.pem…done.

Then generate a certificate signed by the CA that expires in 365 days.

# /opt/zimbra/bin/zmcertmgr createcrt -new -days 365

Validation days: 365
** Creating /opt/zimbra/conf/zmssl.cnf…done
** Backup /opt/zimbra/ssl/zimbra to /opt/zimbra/ssl/zimbra.20101009200401
** Generating a server csr for download self -new -keysize 1024
** Creating /opt/zimbra/conf/zmssl.cnf…done
** Backup /opt/zimbra/ssl/zimbra to /opt/zimbra/ssl/zimbra.20101009200401
** Creating server cert request /opt/zimbra/ssl/zimbra/server/server.csr…done.
** Saving server config key zimbraSSLPrivateKey…failed.
** Signing cert request /opt/zimbra/ssl/zimbra/server/server.csr…done.

Next deploy the certificate.

# /opt/zimbra/bin/zmcertmgr deploycrt self

** Saving server config key zimbraSSLCertificate…done.
** Saving server config key zimbraSSLPrivateKey…done.
** Installing mta certificate and key…done.
** Installing slapd certificate and key…done.
** Installing proxy certificate and key…done.
** Creating pkcs12 file /opt/zimbra/ssl/zimbra/jetty.pkcs12…done.
** Creating keystore file /opt/zimbra/mailboxd/etc/keystore…done.
** Installing CA to /opt/zimbra/conf/ca…done.

Next deploy the CA

# /opt/zimbra/bin/zmcertmgr deployca

** Importing CA /opt/zimbra/ssl/zimbra/ca/ca.pem into CACERTS…done.
** Saving global config key zimbraCertAuthorityCertSelfSigned…done.
** Saving global config key zimbraCertAuthorityKeySelfSigned…done.
** Copying CA to /opt/zimbra/conf/ca…done.

To finish, verify the certificate was deployed to all the services.
