Purple Tree Wiki

This wiki, Purple Tree Wiki, is written in Php. Aside from Parsedown, hightlight.js and MathJax, it is approximately 1000 lines of code.

To install on a local Ubuntu machine, as root:

apt-get install apache2 libapache2-mod-php
a2enmod rewrite
systemctl restart apache2

You can skip much of this if you are installing in /var/www/html, just make sure to chown www-data.www-data /var/www/html so that the wiki can create files there. So as root

cd /var/www/html
tar xvaf ptwiki.tar.gz
mkdir pages versions images
chown -R www-data.www-data /var/www/html

then edit the .htaccess file to ensure it has the correct RewriteBase. And then you're good to go.

RewriteEngine On
RewriteBase /os/linux/ # <-------- THIS LINE NEEDS TO POINT TO WHEREVER YOUR WIKI IS
RewriteRule ^/?$ wiki.php [L]
RewriteRule ^(Index|Recent)$ wiki.php?word=$1 [L]
RewriteCond %{QUERY_STRING} ^$
RewriteRule ^([A-Z][a-zA-Z0-9]*[A-Z][a-zA-Z0-9]*)$ wiki.php?word=$1 [L]
RewriteRule ^([A-Z][a-zA-Z0-9]*[A-Z][a-zA-Z0-9]*)$ wiki.php?word=$1&%{QUERY_STRING} [L]

Now you can stick a PurpleTreeWikiV1 anywhere you like, for example I have one installed at $WEBROOT/lang/php for this wiki. PurpleTreeWikiv2 will have a single index.php you stick in the root of your site and it does all the wikis in one go. But that is a work in progress.

Virtual host

I've installed one on my local network under the name pt1, which means in your hosts file, you want

192.168.4.56 pt1

for example (that Ip address is made up, of course).

You then need to make a directory for the pt1 site, e.g. /var/www/pt1. Then create a
