Zimbra Installation

In this tutorial, we will install Zimbra on Ubuntu 16.04, which is, for now, the latest supported LTS version of Ubuntu.

What we need to start:

• Ubuntu Server 16.04 - 64bit
• root privileges
• Free space 25 GB
• RAM 4 GB

The parameter of my server

• Domain : domain.local
• IP : 192.168.1.101
• Mail : mail.domain.local

Before start following this guide, install Ubuntu 16.04 with the perfect setup guide https://www.howtoforge.com/tutorial/perfect-server-ubuntu-16.04-with-apache-php-myqsl-pureftpd-bind-postfix-doveot-and-ispconfig/

After the fresh install update the system with

After that we are ready to start, first of all, we install LibreOffice with

If using Ubuntu 16.04 and viewing East Asian languages, be sure to install:

Download Zimbra

To download Zimbra go to the page https://www.zimbra.com/try/zimbra-collaboration-open-source/ and compile the form to receive the link of download.

In my case, I can download Zimbra with the following command

Pay attention that the link may change.

Now become root and uncompress the downloaded content

DNS Configuration

When you create a domain during the installation process, Zimbra Collaboration checks to see if you have an MX record correctly configured for that domain. If it is not, an error is displayed suggesting that the domain name have an MX record configured in DNS.

In order to send and receive email, the Zimbra MTA must be configured in DNS with both A and MX records. For sending mail, the MTA uses DNS to resolve hostnames and email-routing information. To receive mail, the MX record must be configured correctly to route the message to the mail server.

During the installation process, Zimbra Collaboration checks to see if you have an MX record correctly configured. If it is not, an error is displayed suggesting that the domain name have an MX record configured in DNS.

You must configure a relay host if you do not enable DNS. After Zimbra Collaboration is installed, go to theadministration console'sGlobal Settings>MTAtab and:

• UncheckEnable DNS lookups.

• Enter therelay MTA addressto use for external delivery.

Install process

Now we can start the install process, with the following commands

The install process will flow as follow

Accept the License Agreement with 'Y'

After that the install process starts, asking some questions, say yes to all except for the voice 'Install zimbra-imapd (BETA - for evaluation only)' which should be left to 'N'.

Now at last question, you can respond 'Y' to start the installation.

As mentioned above, this error is normal if there's no DNS entry for your hostname, if you followed the Perfect Server Setup Guide, there will be no error here, anyway I'll show you how to fix that later. for, now say 'No' to'Change hostname' question.

Next question may be the error about MX, as mentioned above this should be normal if there's no MX associated.

Say 'No' to the question about Change Domain Name

Now a text-based menu should be displayed

The mandatory thing to do here is to set up the admin password, so press button '7' on the keyboard, then '4', then you can set up the Admin password

A password will'be suggested, but you can setup your preffered password.

After that press 'r' to go back in the menu, then press 'a' to save the configuration.

It will ask if you wanna save data to a file, obviouslly say 'Yes', wich is the default answer.

It will ask the name of the file where to save data, you can leave the default, and then it will alert that the system will be modified.

Pay attention to write 'Yes', because for security reasons the default is 'No'

At the end, you will be notified if the installation was succesfull and will get asked if you wanna notify Zimbra about you installation, to help supporto of opn source version i'll suggest to notify, nut it' your choice :)

Now some checks will be started up..

Now you had to do the last setp. We had to set up the syslog configuration files to enable server statistics to display on the administration console, and enable the logger monitor host. The server statistics includes information about the message count, message volume, and anti-spam and anti-virus activity.

Login as zimbra user and lunch the following command

The output should be something like this>

As root, type the following command to enable the server to display statistics

Edit the /etc/default/rsyslog file to add -r to the RSYSLOGD_OPTIONS setting, RSYSLOGD_OPTIONS='-r', then restart the service with

To check your installation you should access the administration console at https://192.168.2.50:7071/ and you should look at the Console Login Page.

To log in, you must use [email protected] (the one you choose during install) with the password you setup

To access the webmail you must go at URL https://IPADDRESS/ to login you must create a user in admin console or use

Prerequisites

In this tutorial, we will see how to upgrade an installation of Zimbra 8.7.11 to Zimbra 8.8.10 (latest version available).

Before starting the upgrade, here some advice, before start check your installation version simply going to your web interface at https://IPADDRESS:7071/, you should see immediately your version at the login dashboard

2FA check

First of all there is a Bug 105056noted a problem that can occur during a rolling upgrade if two factor authentication (2FA) is enabled before all mailbox servers have been upgraded to 8.7. In particular, pre-8.7 mailbox servers are not compatible with 2FA. Accordingly, it is recommended that 2FA is not enabled until all mailbox servers have been upgraded to 8.7.

Database integrity check

Before start the upgrade it is suggested to do a database integrity check, running the command zmdbintegrityreport, wich wil be done entering with the zimbra user

the output should be like this

if something went worng, you need to fix before upgrade.

Update the operating system

Another check to complete, befaore start is to upgrade the operating system, in our case, we use ubuntu 16.04 so the steps are the following, to lunch as root user

Disable SSLv3 Support

If upgrading to ZCS 8.7.0, you need to completely disable SSLv3 support after the upgrade. Disabling SSLv3 is recommended as a result of the SSLv3 vulnerability described in Alert (TA14-290A).

To do that, please refear to the procedure on officiali website Disable SSLv3

Update Default Proxy SSL Ciphers Attribute

Whenever upgrading, it is recommended that you check the values of the following attributes (zmprov gcf <attr>) and compare them with the current default values (zmprov desc -a <attr>).

In addition, it is recommended to make the following changes:

- Remove the following from zimbraReverseProxySSLCiphers:

to do so run the command

When you run the install script, if ZCS is already installed, you will be asked if you want to upgrade.

Zimbra Upgrade

So now, we are prepared to perform the upgrade, in our case from 8.7.11 to 8.8.10, so let's start downloading the lates version

Zimbra Mta Not Starting Download

As you can see, some of the service will be found, as in the output below

Accept the license Agreement, saying 'Y'.

say 'Y' to check message store integrity

say 'Y' to use zimbra repository

At this point install should find you installation ad ask for upgrade, obviouslly say 'Y'

Ath this point you'll be prompted to upgrade the packages he can find, in my installation here's what is fouond

When asked to install zimbra-impad (BETA), say no

At this point upgrade will start

Say 'Y' and upgrade will start. Pay attention that during upgrade all services will be stopped until end of upgrade, so don't do it during working hours.

After a bit of time, upgrade will end succesfully, you can choose, to notify or not Zimbra about your installation

if all is gone right you should arrive at the end

Now try to login to the administration interface and check if the version is changed

In my case, all went fine, and the upgrade process as worked fine.
