certificate removed

Postby chelinux » Wed Sep 19, 2018 5:30 pm

Hello, by mistake it seems to delete the certificates that zimbra installs when the installation is done for the first time, I am trying to generate again and I have this message

[zimbra@mail ~]$ /opt/zimbra/bin/zmcertmgr createcrt -new -days 365

You should first create a ca and then deploy it.

Look at your inbox of PMs please.

Try this if you'd like:

I was able to reproduce and fix the problem you describe in a 8.8.9. This is not a permanent fix, but is good enough for you to start your services and then tune them as you want.
Excecute all these commands as root:

in all your servers:
zmcontrol stop

In all your servers:
rm -rf /opt/zimbra/ssl/*
rm -rf /opt/zimbra/.rnd
su - zimbra -c '/opt/zimbra/common/bin/keytool -delete -alias my_ca -keystore /opt/zimbra/common/etc/java/cacerts -storepass changeit'
chmod -R 0755 /opt/zimbra/ssl
chown -R zimbra:zimbra /opt/zimbra/ssl

In the servers where you have the store deployed:
su - zimbra -c '/opt/zimbra/common/bin/keytool -delete -alias jetty -keystore /opt/zimbra/mailboxd/etc/keystore -storepass `zmlocalconfig -s -m nokey mailboxd_keystore_password`'

In the server where you have your ldap:
su - zimbra -c '/opt/zimbra/bin/zmcertmgr createca -new'
su - zimbra -c '/opt/zimbra/bin/zmcertmgr deployca -localonly'
su - zimbra -c '/opt/zimbra/bin/zmcertmgr createcrt -new'
su - zimbra -c '/opt/zimbra/bin/zmcertmgr deploycrt self'
su - zimbra -c 'zmcontrol start'

At this point, services should be able to start in the server where you have your ldap service installed.

In the rest of your servers:
su - zimbra -c 'mkdir -p /opt/zimbra/ssl/zimbra/ca'
su - zimbra -c 'chmod -R 0750 /opt/zimbra/ssl/zimbra'

Now, copy the content of /opt/zimbra/ssl/zimbra/ca that exists in your ldap server, to the rest of your servers. You could use scp to do it from your ldap server it would look something like this: scp /opt/zimbra/ssl/zimbra/ca/* root@ipofyourotherserver:/opt/zimbra/ssl/zimbra/ca

On each of your other servers:
su - zimbra -c 'opt/zimbra/bin/zmcertmgr deployca'

On your ldap server:
su - zimbra -c "/opt/zimbra/bin/zmcertmgr deploycrt self -allserver"

On the rest of your servers:
su - zimbra -c 'zmcontrol restart'

Good luck!
