How To Install TWiki on SME Server

Home Page

http://twiki.org

Description

TWiki is a flexible, powerful, and easy to use enterprise wiki,enterprise collaboration platform and knowledge management system. It is a Structured Wiki, typically used to run a project development space, a document management system, a knowledge base, or any other groupware tool, on an intranet or on the internet. Web content can be created collaboratively by using just a browser. Users without programming skills can create web applications. Developers can extend the functionality of TWiki with Plugins. TWiki fosters information flow within an organization; lets distributed teams work together seamlessly and productively; and eliminates the one-webmaster syndrome of outdated intranet content.

Download

Installation

Create a directory named twiki under /opt dir.

Extract all content from twiki tar file under /opt/twiki (bin, data, etc)

Follow the twiki instructions about perl dependancy and requirement, and configure.

Create a new file named "mod_perl_startup.pl" under /opt/twiki/tools/ with this content: 

$ENV{MOD_PERL} =~ /mod_perl/ or die "mod_perl_startup called, but mod_perl not used!"; 
use lib qw( /opt/twiki/bin );
require 'setlib.cfg';
1;

Create a custom template named "98Twiki" under /etc/e-smith/templates-custom/etc/httpd/conf/httpd.conf with the following content. 

# Autogenerated httpd.conf file for TWiki.
# Generated at http://twiki.org/cgi-bin/view/TWiki/ApacheConfigGenerator
# For TWiki version 4.2.X   
# We set an environment variable called blockAccess.
#
# Setting a BrowserMatchNoCase to ^$ is important. It prevents TWiki from
# including its own topics as URLs and also prevents other TWikis from
# doing the same. This is important to prevent the most obvious
# Denial of Service attacks.
#
# You can expand this by adding more BrowserMatchNoCase statements to
# block evil browser agents trying the impossible task of mirroring a twiki
#
# Example:
# BrowserMatchNoCase ^SiteSucker blockAccess
# BrowserMatchNoCase ^$ blockAccess

Then save, expand, and restart httpd service.

With this templates you not need to login at twiki at /twiki/bin/... You only go to yourdomain/twiki.
