Ubuntu Boot Camp 2013
The Freedom Is Yours!!

Basic Server Installation

For a overview of Ubuntu Server 12.04, visit this website:
https://help.ubuntu.com/12.04/serverguide/index.html


Tanzania is not shown in the list, so we select other, and choose
Africa, then we select Tanzania. The same principal about updates
and correct location that we discussed on the desktop side also
applies for the server


Host Name: Based on the naming protocol in your organization. For
example we name our servers such as Top Gun or it could be location
related..Costech1


Admin Account..same principal as on the desktop side as the Root
account is disabled by default, this account will allow you to assume
sudo privileges.
Create a user, for example the user Administrator with the user name
administrator (don't use the user name admin as it is a reserved name
on Ubuntu 12.04):


Create a user, for example the user Administrator with the user name
administrator (don't use the user name admin as it is a reserved name
on Ubuntu 12.04):


For this example we don't need to have an encrypted private
directory, so choose No.


Now you have to partition your hard disk. For this exercise select
Guided - use entire disk and set up LVM - this will create one volume
group with two logical volumes, one for the / file system and another
one for swap (of course, the partitioning is totally up to you - if you
know what you're doing, you can also set up your partitions manually).

Partitioning Overview

Once a disk is partitioned, an OS must have some way to access the data on the
partitions. In DOS and Windows, this is done by assigning a drive letter, such as C: or D:,
to each partition. (DOS and Windows use partition type codes to decide which partitions get
drive letters and which to ignore.)
Linux, though, doesn’t use drive letters; instead, Linux uses a unified directory tree. Each
partition is mounted at a mount point in that tree. A mount point is a directory that’s used as
a way to access the filesystem on the partition, and mounting the filesystem is the process
of linking the filesystem to the mount point.
For instance, suppose that a Linux system has three partitions: the root (/) partition,
/home, and /usr. The root partition holds the basic system files, and all other partitions are
accessed via directories on that filesystem.
If /home contains users’ home directories, such as sally and sam, those directories will be
accessible as /home/sally and /home/sam once this partition is mounted at /home. If this
partition were unmounted and remounted at /users, the same directories would become
accessible as /users/sally and /users/sam.

Partitioning Overview


After the reboot, you can login with your previously created username
(eg.Administrator) Because we must be root for the rest of this process,
either we start each command with sudo
or we can become root now by typing: sudo su
Or you may activate your root account by creating the password....
sudo passwd root

Install a text editor for our work. I prefer to use Nano.
sudo apt-get install nano

SSH Access for troubleshooting

ssh: secure shell access
Install ssh on both the your own computer and the remote computer/server you
would like to administer.
CODE: sudo apt-get install ssh
(If you get an error that it can't find a package, run apt-get update first)
IP address of remote machine: you will need the IP address whether it is
static or dynamic in order to connect. If you are on the same subnet then it will
be straightforward. However if you are coming from outside the network, the
net admin will have to enable port 22 on the router in order for you to have
access
Password of admin or root account: In order to you to do the tasks required
on the command line you will need to be able to login to the machine

Setting Static IP Address

Static IP Address
Your server should be configured with a static IP address for several reasons
and you will need to know the information in the image below
CODE: sudo nano /etc/network/interfaces

Then restart your network....
CODE: sudo /etc/init.d/networking restart

Common Open Source Programs to Install on Your Server

OpenLDAP: is an open source implementation of the Lightweight Directory Access Protocol. It
is an alternative to MS Active Directory.
Site - openldap.org
Postfix: a mail server SMTP program which is an alternative to Sendmail
Site: postfix.org
LAMP: Linux Apache MySQL Php stack
https://help.ubuntu.com/community/ApacheMySQLPHP
PhpMyAdmin: a tool written in PHP to adminster MYSQL databases over the web,
Site - phpmyadmin.net
Asterisk: Asterisk turns an ordinary computer into a communications server. Asterisk powers
IP PBX systems, VoIP gateways, conference servers and other custom solutions.
Site - asterisk.org
Dansguardian: It filters the actual content of pages based on many methods including phrase
matching, PICS filtering and URL filtering.
