Install Zimbra Mailbox – Zimbra Multi Server on Ubuntu 20.04 (Part 2)

Hi Dude, I will continue my article that I posted earlier about installing zimbra multi server on Ubuntu 20.04. In the previous post, the Zimbra LDAP installation has been completed. Now we will continue with the Zimbra Mailbox Multi Server Installation stage.

Before Install Zimbra Mailbox 1 – Multi Server

Basically the same as in Zimbra LDAP preparation, we can repeat the same steps so that this article is not long. I will write a summary here.

Preparation:

1. Set IP address static and /etc/hosts.
2. Set Hostname and Date Time.
3. Disable firewall.
4. Install NTP Server. In /etc/ntp.conf disable all server, and add "server 10.12.12.10 iburst".
5. By default, Ubuntu 20/04 bundling systemd-resolved. Edit /etc/systemd/resolved.conf and set like below.

[Resolve]
DNS=10.12.12.10
#FallbackDNS=
Domains=habibza.in

After that finished, test lookup to other server. It should be answered according to the IP address in the DNS field. As we know, 127.0.0.53 is port systemd-resolver.

root@mbox1:~# nslookup ldap.habibza.in
Server:         127.0.0.53
Address:        127.0.0.53#53

Non-authoritative answer:
Name:   ldap.habibza.in
Address: 10.12.12.10

root@mbox1:~# nslookup mail.habibza.in
Server:         127.0.0.53
Address:        127.0.0.53#53

Non-authoritative answer:
Name:   mail.habibza.in
Address: 10.12.12.12

Next, test the NTP client. Whether it can query the NTP server 10.12.12.10 or not. Use command ntpq -c sysinfo. Look red line, there is flag sync_ntp. That sign can query properly to ntp server 10.12.12.10.

root@mbox1:~# ntpq -c sysinfo
associd=0 status=0615 leap_none, sync_ntp, 1 event, clock_sync,

If show dialog like below, press 1.

Next, note the line marked with an asterisk ‘******’ with value “UNSET”.

• Ldap Master Host : ldap.habibza.in
• Ldap admin password: find password in host zimbra ldap.

The trick is to login to the Zimbra LDAP host. See red line below.

root@ldap:~# su - zimbra
zimbra@ldap:~$ zmlocalconfig -s zimbra_ldap_password ldap_master_url
zimbra_ldap_password = WtHcMRpTV
ldap_master_url = ldap://ldap.habibza.in:389

And then, set timezone zimbra. Type number ‘8’ and then ENTER. fill with number ’51’. That is Asia/Bangkok.

If finished, type ‘r’. And see asterisk in number ‘9’.

Fill SMTP Server hostname: mta.habibza.in. We will config later after this server install finished.

Press ‘r’ to return. And follow wizard installation until finished.

root@mbox1:~# su - zimbra
zimbra@mbox1:~$ zmcontrol status
Host mbox1.habibza.in
        logger                  Running
        mailbox                 Running
        service webapp          Running
        snmp                    Running
        spell                   Running
        stats                   Running
        zimbra webapp           Running
        zimbraAdmin webapp      Running
        zimlet webapp           Running
        zmconfigd               Running

Ok, we already finished installation zimbra Part 2. Next install MTA server in Part 3. Plaase make sure everything running well and not conflict port. Can ping and lookup between server.
