"DokuWiki is a standards-compliant, simple-to-use wiki which allows users to create rich documentation repositories. It provides an environment for individuals, teams and companies to create and collaborate using a simple yet powerful syntax that ensures data files remain structured and readable outside the wiki."

"Unlimited page revisions allows restoration to any earlier page version, and with data stored in plain text files, no database is required. A powerful plugin architecture allows for extension and enhancement of the core system. See the features section for a full description of what DokuWiki has to offer."[1]

In other words, DokuWiki is a wiki written in PHP and requires no database.

Initial Notes

DokuWiki should work on any web server which supports PHP 5.1.2 or later. As the requirements may change over time, you should consult the requirements page for DokuWiki for additional details.

It is strongly recommend to read through the appropriate sections of DokuWiki's security page for your web server. Most popular web servers are covered but there are generic instructions as well.

The package in [community] unpacks DokuWiki at /srv/http/dokuwiki and changes ownership to the "http" user. This should work fine for most popular web servers as packaged for Arch.

Installation

  1. Install your web server of choice (e.g. Apache or lighttpd) and configure it for PHP. As mentioned above, DokuWiki has no need for a database server so you may be able to skip those steps when setting up your web server.
  2. Install dokuwiki from [community] with pacman.
  3. With your web browser of choice, open http://<your-server>/dokuwiki/install.php and continue the installation from there.

Alternatively, if you would like to install from tarball, you can read from http://www.dokuwiki.org/Install. Generally the procedure is the same as above. Instead of using pacman, you will need to download the tarball, unpack it to your server's document root (e.g. /srv/http/dokuwiki), and chown to the appropriate user (e.g. "http").

lighttpd Specific Configuration

Edit the /etc/lighttpd/lighttpd.conf file as per the dokuwiki instructions (might contain updated information).

Under the line:

 
$HTTP["url"] =~ "\.pdf$" {
  server.range-requests = "disable"
}

add this:

# subdir of dokuwiki
# comprised of the subdir of the root dir where dokuwiki is installed
# in this case the root dir is the basedir plus /htdocs/
# Note: be careful with trailing slashes when uniting strings.
# all content on this example server is served from htdocs/ up.
#var.dokudir = var.basedir + "/dokuwiki"
var.dokudir = server.document-root + "/dokuwiki"

# make sure those are always served through fastcgi and never as static files
# deny access completly to these
$HTTP["url"] =~ "/\.ht" { url.access-deny = ( "" ) }
$HTTP["url"] =~ "/_ht" { url.access-deny = ( "" ) }
$HTTP["url"] =~ "^" + var.dokudir + "/bin/"  { url.access-deny = ( "" ) }
$HTTP["url"] =~ "^" + var.dokudir + "/data/" { url.access-deny = ( "" ) }
$HTTP["url"] =~ "^" + var.dokudir + "/inc/"  { url.access-deny = ( "" ) }
$HTTP["url"] =~ "^" + var.dokudir + "/conf/" { url.access-deny = ( "" ) }

These entries give some basic security to DokuWiki. lighttpd does not use .htaccess files like Apache. You CAN install with out this, but I would NEVER recommend it.

Restart lighttp:

 # /etc/rc.d/lighttpd restart

Post Installation

Cleaning Up

After configuring the server remove the install.php file!

 # rm /srv/http/dokuwiki/install.php

Installing Plugins

Many community created plugins can be found here

They can be added through the web interface (as well as updated) through the Admin menu.

Backing Up

It is very trivial to backup DokuWiki, since there is no database. All pages are in plain text, and require only a simple tar, or rsync.

A quick breakdown of the directories of interest in the current (2008-05-05) version:

 /dokuwiki/data/  =>  All User Created Data
 /dokuwiki/lib/plugins/  =>  All User Added Plugins
