-->



Installation of prerequisites
connect to your server, get root privileges and install this package.

apt-get install libgmp10 libperl5.18 unzip pax sysstat sqlite3 dnsmasq wget


Configure hostname and DNS Server

Step 1 - Edit hostname and hosts
vim /etc/hostname
-->
change your hostname with this 'zimbramail.faceitnet.com.au'.


vim /etc/hosts
add this line:
-->
192.168.200.10   zimbramail.faceitnet.com.au zimbramail


Step 2 - Edit dnsmasq configuration
-->
vim /etc/dnsmasq.conf

-->
Reboot

Installing Zimbra

Step 1 - Download Zimbra and extract it
Download using the following command if Download doesn’t work then download manually and upload to server using FTP service. (Need to configure FTP)
--> wget https://files.zimbra.com/downloads/8.6.0_GA/zcs-8.6.0_GA_1153.UBUNTU14_64.20141215151116.tgz

Extract the file using the following command:


Change the directory to extracted directory:
-->
cd zcs*

-->
Now install the package by run the ./install.sh command


-->
Continue the installation by Pressing Y


-->
You need to wait, because this installation takes some time.


-->

next step is configure "zimbra-store" for getting admin password.



-->
In my configuration you could see my Master DNS IP address was not configured, so I had to configure it to finish the configuration, Until that you will not be permitted to Apply configuration ( a to apply Configuration )

It will take some time to finalize all the configuration


Testing Zimbra
To test your zimbra server is running, you can type a command
su - zimbra
zmcontrol status
-->
try to access zimbra from web browser.  https://192.168.200.10/

-->

or try admin page " https://192.168.200.10:7071/ ".


-->
Once you have configured the Zimbra mail server, test the server by sending mails from two acceounts that you have created.
