DokuWiki

"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."

「DokuWiki はユーザーがリッチなドキュメントリポジトリを作成することを可能にする標準規格に準拠した、使いやすいウィキです。これは、作成する個人、チームや企業のための環境を提供し、構造化されたデータファイルによりウィキ外でも可読性のあるシンプルで強力な構文を使用して共同作業を可能とします」

「無制限のページのリビジョンは、以前のページのバージョンに復元を可能にし、プレーンテキストファイルに格納されたデータは、データベースを必要としません。強力なプラグインアーキテクチャは、コアシステムの拡張・強化することができます。DokuWiki が提供する完全な説明については、機能のセクションを参照してください」"[1]

言い換えると、DokuWikiはPHPで書かれたウィキであり、何のデータベースを必要としません。

初期の注意事項

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 /usr/share/webapps/dokuwiki with the configuration files in /etc/webapps/dokuwiki and the data files in /var/lib/dokuwiki/data. It also changes the ownership of the relevant files to the "http" user. This should work fine for most popular web servers as packaged for Arch.

インストール

1. Install your web server of choice (e.g. Apache, nginx 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. Configure web server for dokuwiki (see section below)
4. 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").

設定

If you are using lighttpd or nginx you need to adjust the open_basedir in /etc/php/php.ini to include the dokuwiki directories (php forbids following symbolic links outside of the allowed scope):

/etc/php/php.ini

open_basedir = /srv/http/:/home/:/tmp/:/usr/share/pear/:/usr/share/webapps/:/etc/webapps/dokuwiki/:/var/lib/dokuwiki/

Also uncomment the following line.

/etc/php/php.ini

extension=gd.so

Dokuwiki needs this library for resizing images.

Apache

The package should add the file /etc/httpd/conf/extra/dokuwiki.conf with the following contents:

Alias /dokuwiki /usr/share/webapps/dokuwiki
<Directory /usr/share/webapps/dokuwiki/>
    Options +FollowSymLinks
    AllowOverride All
    order allow,deny
    allow from all
    php_admin_value open_basedir "/tmp/:/usr/share/pear/:/usr/share/webapps/:/etc/webapps/dokuwiki/:/var/lib/dokuwiki/"
</Directory>

If you are running Apache 2.4 or newer, you will have to change the following lines:

    order allow,deny
    allow from all

to read:

    Require all granted

Include the newly created file in the Apache configuration by placing the following line at the end of /etc/httpd/conf/httpd.conf:

Include conf/extra/dokuwiki.conf

Make sure the folders /etc/webapps/dokuwiki and /var/lib/dokuwiki are owned by user and group "http". You may relocate these directories if you like as long as you update the references in /etc/httpd/conf/extra/dokuwiki.conf respectively.

Afterwards restart Apache:

 # systemctl restart httpd.service

Then finish the installation by running the dokuwiki/install.php script in your browser.

lighttpd の設定

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

Make sure the modules mod_access and mod_alias are loaded. If not, load them by adding the following to /etc/lighttpd/lighttpd.conf:

server.modules += ("mod_access")
server.modules += ("mod_alias")

mod_access provides the url.access-deny command, which we are using from this point.

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"] =~ "^" + var.dokudir + "/(bin|data|inc|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.

Add alias somewhere in lighttpd or fastcgi conf file:

alias.url += ("/dokuwiki" => "/usr/share/webapps/dokuwiki/")

Restart lighttpd:

 # systemctl restart lighttpd

nginx

Add the following location blocks to your /etc/nginx/nginx.conf.

#Assuming that the root is set to /usr/share/webapps.
#You may need to adjust your location blocks accordingly.
location ~^/dokuwiki/(data|conf|bin|inc)/ { deny all; } # secure DokuWiki
location ~^/dokuwiki/\.ht { deny all; } # also secure the Apache .htaccess files
location ~^/dokuwiki/lib/^((?!php).)*$ { expires 30d; } # no need to serve non .php files through fastcgi, so we catch those requests here.
location ~^/dokuwiki/.*\.php$ {
            include fastcgi.conf;
            fastcgi_pass unix:/run/php-fpm/php-fpm.sock;
        }

Restart nginx

 # systemctl restart nginx

インストール後の作業

不要なファイルの削除

After configuring the server remove the install.php file!

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

プラグインのインストール

Many community created plugins can be found here

They can be added through the web interface (as well as updated) through the Admin menu. Some plugins cannot be downloaded, if they go over ssl (e.g. git). Uncomment following line in /etc/php/php.ini:

extension=openssl.so

バックアップ

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
