Installing the LAMP stack on Debian Wheezy

Otherwise known as a LAMP server, the LAMP software stack consists of GNU\Linux as the operating system, Apache as the Web server, MySql for a database, and PHP (or possibly Pearl or Python) as the programming language used to host a Web application.

I’m going to assume a minimal install (I’ll be using debian-7.6.0-i386-CD-1.iso)
[http://cdimage.debian.org/debian-cd].

First we’ll need to make sure we have all the necessary repos in our
/etc/apt/sources.list file. If you installed from a complete
installation image you probably won’t need to mess with this, but
cat out the sources list and make sure you have the following or
something simialr.

root@debian32-base:# cat /etc/apt/sources.list
deb http://ftp.us.debian.org/debian stable main contrib non-free
deb http://ftp.debian.org/debian/ wheezy-updates main contrib non-free
deb http://security.debian.org/ wheezy/updates main contrib non-free

Okay, now update apt and install our software packages.
You will need to set a password for MySql’s root user.

root@debian32-base:# apt-get update

Right about now, you get hit with the ncurses screen


And then the installation will finish uninterrupted

Now you should be able to navigate to the server with a Web Browser. Just type
the computer’s IP address into the address bar.


What we don’t know for sure at this point is if PHP is working. Let’s rename
the default index.html file to a PHP file (index.php)
(FYI: to rename in the terminal, we use the move mv command).
Then we can open it with a text editor and add some PHP code and see if it’s
working.

root@debian32-base:~# mv /var/www/index.html /var/www/index.php
root@debian32-base:~# vim /var/www/index.php
<html><body><h1>It works!</h1>
<p>This is the default web page for this server.</p
<p>The web server software is running but no content has been added, yet.</p>
</body>
<?php echo('Hello World'); ?>
</html>
