Install PHP apps on the VM

Allowing a folder to be accessible

After logging into the VM (either with the VM Player or through SSH), in order to allow a folder to be web-accessible, find your Apache configuration file which contains the MindTouch rewrite rules (on the VMs, this file is /etc/apache2/sites-available/dekiwiki). To edit this file, run:
pico /etc/apache2/sites-available/dekiwiki

A document similar to this one will be present. The section of interest is the part that tells MindTouch which folders to ignore. Note that at the writing of this document, the relevant section looks like this: (if it looks slightly different, don't worry - the documentation just hasn't been updated!)

RewriteCond %{REQUEST_URI} !^/(@api|editor|skins|config|@gui)/
RewriteCond %{REQUEST_URI} !^/index\.php
RewriteCond %{REQUEST_URI} !^/favicon\.ico$
RewriteCond %{REQUEST_URI} !^/robots\.txt$
RewriteCond %{QUERY_STRING} ^$ [OR] %{REQUEST_URI} ^/Special:Search
RewriteRule ^/(.*)$ /index.php?title=$1 [L,QSA,NE]

 The first line tells MindTouch which folders to ignore. Simply update that first line to add the folders where to install the PHP applications:

RewriteCond %{REQUEST_URI} !^/(@api|editor|skins|config|@gui|blog)/

In this example, the blog folder was also added. As many folders as desired can be added here.

After exiting out of pico, (Ctrl+X, "Y" for save), restart Apache:
/etc/init.d/apache2 restart

Now try accessing the new folder - it should return an Apache page and not a MindTouch page! After doing this, follow the instructions for installation of any PHP app. Easy!

Below is a step-by-step look at how to install WordPress as an example.

Tell Apache to allow access to /blog/

Edit the rewrite rules:
pico /etc/apache2/sites-available/dekiwiki

Update the line that resembles with a "|blog":

RewriteCond %{REQUEST_URI} !^/(@api|editor|skins|config|@gui)/

becomes

RewriteCond %{REQUEST_URI} !^/(@api|editor|skins|config|@gui|blog)/

Restart Apache:
/etc/init.d/httpd restart
or /etc/init.d/apache2 restart

Now, certain versions of Deki Wiki are installed in /var/www/dekiwiki and certain versions are installed in /var/www/deki-hayes; either one or the other will exist. Whichever one exists have to go to that folder:
cd /var/www/dekiwiki;
or
cd /var/www/deki-hayes/;

Download the .tar.gz version of Wordpress from their download page:
wget http://wordpress.org/latest.tar.gz

Unzip Wordpress:
tar -xf latest.tar.gz --gzip

WordPress unzips into a wordpress folder, so rename it:
mv wordpress blog

Make the blog folder writable for install:
chmod 775 blog

Give ownership of the blog to Apache:
chown -R www-data.www-data blog

Connect to mySQL to install the WP db:
mysql -uroot -ppassword

Once connected to the mySQL console, create the mySQL DB:
create database wordpress;

Quit the mySQL console:
exit;

Now, visit http://{mindtouch-url}/blog/ and the Wordpress installation screen should pop-up!

Observe, http://{mindtouch-url}/Blog/ or http://{mindtouch-url}/blog might not work, it is important
that it is typed in exactly http://{mindtouch-url}/blog/ (with lowercase letters and a slash at the end).
