Virtual domains

...the standard installation forThings Lab meetings

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

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

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 foldercd (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

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

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

Setup a local domain

At the command prompt go in /etc/ foldercd /etc/

Edit the file hosts with root permissions using visudo 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):127.0.0.1test

Save and quit with the command :wq

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)

Setup a virtual host in apache

At the command prompt go in /etc/apache2/sites-enabled foldercd /etc/apache2/sites-enabled/

Add a new file root permissions using visudo vi test (use your name instead)

Start the insert mode and paste the text of the next page, change from test to your name!

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!):
