Base installation on ubuntu 12.04 LTS

We are startigng with a bare ubuntu system with only ssh enabled.

First of all please update all packages and do some configurations:

vim /etc/apt/sources.list

Uncomment the following line:

deb http://archive.canonical.com/ubuntu precise partner

We install the apt-add-repository-script to be able to use the zentyal repository afterwards and do a full system upgrade:

apt-get install -y python-software-properties
apt-add-repository ppa:zentyal/3.0
apt-get update
apt-get dist-upgrade
apt-get clean

Then add an administrative account for zentyal.

To be able to access the webinterface you have setup an administrativ user which belongs to the admin group. This is NOT the ubuntu adm group! You have to create the group first:

groupadd admin
useradd myAdmin
passwd myAdmin
usermod -G admin -a myAdmin
...

Pleas verify, that the newly created user is part of the new group with:

su my Admin
groups

Finally reboot the system:

reboot

Install Zentyal

The base system then will be install via the command

apt-get -y install zentyal

This will install all prerequisites. Please prepare to have:

• the or a mysql root password
• the port for the webinterface

I suggest 444 for the webinterface, so it would not be in conflict with https-pages on your site (you can then access the webinterface via http://vserver:444).

Configure the services

You will now be able to access the webinterface via http://vserver:444.

There choose the services you like. It is always good, of possible to to a snapshot after each of this steps and test, if everything went ok!

Firewall

IMPORTANT: Alter your firewall settings to enable the Zentyal administration !!!

Otherwise you won't be able to access the webinterface.

In case you forget this you can temporaryly disable the firewall via commandline and alter this settings.

/etc/init.d/zentyal firewall stop

Network

Be sure to enable the WAN switch.

Mail

First of all we like to install an e-mail-system. This is what most users want, when they install zentyal on an vserver.

If you only choose the mail plugin, several plugins will be installed, too:

In the next steps, it is important that you

1. choose eth0 as interface (see picture) and later
2. DHCP for the configuration of eth0.
3. Directly afterwards you will be asked for the Kerberos REALM. Please use the domain name of your server, if configured. If not SKIP this step for now!

Changing the REALM

Sometimes it can be necessary to alter the realm (kerberos). This will brake all user related modules and forces them to reinstall:

/usr/share/zentyal-users/reinstall

1. Then klick on the "Ally"-Button on the upper right corner of the web-interface.
2. Then go to "Users" -> "Mode...", change the realm and apply.
3. Then you have to reenable the "Users"-module and apply the changes.
4. Then you can also reenable the "Samba"-module and apply the changes.
