The Apache2 web server is a very powerful and useful web server that is used to host websites all around the world. This is available for the Ubuntu 12.10 Linux distribution. To install this; type this command.
sudo apt-get install apache2 mysql-server php5
This command will install the Apache2 and MySQL database server packages, as well as the PHP language required to run just about every web application out there; and start the Apache2 web server upon completion. The default wwroot for the Apache2 web server is the /var/www folder that will contain a small HTML greeting page that is visible if you visit the http://localhostaddress in your browser. Below is the result of all this effort; the Apache web server running on your PC.
If you install the WordPress package with the
sudo apt-get install wordpress command in Ubuntu 12.10 the blogging package will be installed to the /usr/share/wordpress folder; you will need to copy the contents of that folder into the /var/www folder to be able to get WordPress working with Apache. Another way is just to download the latest tarball of WordPress from the website and unpack that into the /var/www folder.
There is a nice guide here that explains how to set up the database connection and get the WordPress package working with MySQL: http://ubuntuserverguide.com/2012/05/how-to-install-latest-wordpress-in-ubuntu-server-12-04-lts.html. These instructions work perfectly with the Apache2 version in Ubuntu 12.10. There is a full tutorial on installing the Ubuntu 12.10 server distribution here: http://www.howtoforge.com/perfect-server-ubuntu-12.10-apache2-bind-dovecot-ispconfig-3; this will be useful if you want to install a Linux server from the ground up. Below I have also added a nice video that shows how to install an Ubuntu server with the 12.04 distribution; this is also applicable to the 12.10 release.
