On In Zimbra Collaboration Leave a comment
In this deployment we will have 2 Zimbra Open Source Edition servers running on the internal network. In most cases we would recommend running Zimbra MTA on the DMZ but in this deployment we already had existing gateway scanning messages.
Order of Installation
- Zimbra LDAP srv
- Zimbra Mailbox srv
- Zimbra MTA srv
- Zimbra Proxy srv
Servers
mtasrv.demo.org 172.16.10.5 – Roles=LDAP,MTA,Proxy
mailboxsrv.demo.org 172.16.10.6 – Roles=Mailbox
Installation
On both servers
Disable selinux and firewalld
Disable selinux and firewalld
vi /etc/selinux SELINUX=disabled
systemctl stop firewalld systemctl disable firewalld
Set hostname and install required packages
hostnamectl set-hostname mtasrv.demo.org yum install net-tools wget nc perl-core unzip sysstat
you need to set up an MX record for the DOMAIN, which points to the A record for the HOST, which will be the IP ADDRESS of the box running zimbra
Add following entries to your host files
vi /etc/hosts 172.16.10.5 mtasrv.demo.org mtasrv 172.16.10.6 mailboxsrv.demo.org mailboxsrv
Download zimbra zcs-8.6.0_GA_1153.RHEL7_64.20141215151110.tgz to /root directory and untar it.

Make sure you enter correct name for LDAP server
Common configuration 1) Hostname: mailboxsrv.demo.org 2) Ldap master host: mtasrv.demo.org 3) Ldap port: 389 4) Ldap Admin password: set 5) LDAP Base DN: cn=zimbra 6) Secure interprocess communications: yes 7) TimeZone: America/New_York 8) IP Mode: ipv4 9) Default SSL digest: sha256
Make sure you go ober the menu and make sure all passwords are set and SMTP host is set to mtasrv.demo.org
One of the important things here is to enable use of proxy. Although this can be done later, it just makes more sense to do it during install.

Set Up the SSH Keys – both servers
We need to manually populate ssh keys on each server
su - zimbra zmupdateauthkeys
Enabling Server Statistics – both servers
In order for the server statistics to display on the administration console, the syslog configuration files must be modified. On each server, as root, type
/opt/zimbra/libexec/zmsyslogsetup vi /etc/rsyslog.conf # Provides UDP syslog reception $ModLoad imudp $UDPServerRun 514 # Provides TCP syslog reception $ModLoad imtcp $InputTCPServerRun 514 service rsyslog restart
Verify configuration
