In-Depth Information
By default, files for the web server are stored in the /var/www folder, which is writeable only
by the root user. To adjust where Apache looks for its files—to move the website onto more
capacious external storage, for example—edit the text file 000-default found in the folder
/etc/apache2/sites-enabled . For more information on configuring Apache, PHP and
MySQL, type the following commands at the terminal or console:
man apache2
man php5
man mysql
Installing WordPress
One of the most popular blogging platforms around, WordPress is an open-source project
that aims to give users a simple yet powerful platform to create attractive, interactive web-
sites. WordPress is built on a base of PHP and JavaScript, and offers an attractive web-based
interface for creating rich websites. For example, some of the most popular news sites in the
world are built on a customised WordPress platform.
To install WordPress on the Raspberry Pi, type the following command at the terminal or console:
sudo apt-get install wordpress
Like the LAMP stack, WordPress comes with a selection of dependencies (see Figure 10-5).
You'll need to make sure you have around 37 MB of free space on the Pi's SD card for the full
installation, in addition to the 113 MB required for the LAMP stack. If you have enough free
space, type Y to continue the installation process.
When WordPress has finished installing, its default installation directory— /usr/share/
wordpress —needs to be linked into the /var/www directory in order for Apache to see the
files. Type the following command at the terminal:
sudo ln -s /usr/share/wordpress /var/www/wordpress
Linking a file or directory is different to moving: the files for WordPress now exist in both /
usr/share and /var/www simultaneously, without taking up any extra space on the Pi's
SD card. If you've told Apache to use a different directory for the default website, change the
linking command accordingly. Next, run the WordPress MySQL configuration script using
the following command, typed as a single line:
sudo bash /usr/share/doc/wordpress/examples/setup-mysql ↵
-n wordpress localhost
