1. >_ Things Lab
Virtual domains
...the standard installation for
Things Lab meetings

2. Check an installed package
● Should be checked if all the packages are installed
correctly, if not install the package. As example for
unzip:
(should be executed at command prompt/terminal)
dpkg --get-selections | grep unzip
sudo apt-get install unzip

3. Check and install all packages
● Should be installed all the following packages:
php5, php-mysql, phpmyadmin, mysql-client, mysql-
server and apache2
(check one by one or... directly install all if not yet
installed...)
sudo apt-get install php5 php5-mysql apache2
phpmyadmin mysql-client mysql-server

4. Play with vi, the easy way
● What is it vi? Google it or RTFM (at command
prompt, man vi).
● Open the terminal and go in your home folder
cd (enter)
● Open a new file (or existing if was already present,
to open as root use sudo before the vi command)
and try to use some basic commands of vi
● vi aaa.txt (enter)
(esc) allows to enter in the command mode

5. Play with vi, part 1
(in command mode) i allows to enter in the insert
mode
(in command mode) x allows to delete a character
(in command mode) dd (double d) allows to delete a
line
(in insert mode, means you are editing) press esc to
enter in command mode

6. Play with vi, part 2
(in command mode) :q exit from the editing of the
file, do not save changes
(in command mode) :wq exit from the editing of the
file, save all changes
any other command? RTFM :-)
http://en.wikipedia.org/wiki/RTFM
If you have any problem, go in command mode and
quit without saving the changes

7. Setup a local domain
● At the command prompt go in /etc/ folder
cd /etc/
● Edit the file hosts with root permissions using vi
sudo vi hosts
● In vi move using the arrows and add a new line, the
line should be as the following (instead test use your
name):
127.0.0.1 test
● Save and quit with the command :wq

8. Check the local domain
● At the command prompt check if the domain is
responding to pings (what is it ping? RTFM!):
ping test (in your case, your name) (enter)
● Create the folder where you will have your virtual
domain:
sudo mkdir /var/www/test/ (enter)

9. Setup a virtual host in apache
●
At the command prompt go in /etc/apache2/sites-
enabled folder
cd /etc/apache2/sites-enabled/
● Add a new file root permissions using vi
sudo vi test (use your name instead)
● Start the insert mode and paste the text of the next
page, change from test to your name!

10. Virtualhost configuration
<VirtualHost *:80>
ServerAdmin webmaster@localhost
ServerName test
DocumentRoot /var/www/test
<Directory />
Options FollowSymLinks
AllowOverride None
</Directory>
<Directory /var/www/test/>
Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
allow from all
</Directory>
ErrorLog /var/log/apache2/test-error.log
</VirtualHost>

11. Add files to the virtual domain
● In /var/www/test/ create a simple html file and insert
some text:
sudo vi /var/www/test/index.html (enter)
(now you know how to do it! :-) )
● In /var/www/test/ create a simple php (test.php) file
and the following insert text (is ok in one line!):
<?php print phpinfo(); ?>
