====== Руководство по установке ======

Выполните в терминале:

<code bash>sudo apt-get install dokuwiki</code>
  
Устраним проблемы, которые могут помешать нам запустить установщик DokuWiki в браузере:
<code bash>sudo nano /etc/apache2/conf.d/dokuwiki.conf</code>
в убунту 16 это <code bash> sudo nano /etc/dokuwiki/apache.conf</code>
найдите строку 
<code apache>Alias /dokuwiki /usr/share/dokuwiki/</code>
Теперь удалите слэш, следующий после /usr/share/dokuwiki. После этого файл должен содержать только:
<code apache>Alias /dokuwiki /usr/share/dokuwiki</code>
Нажмите ctrl-X для выхода из редактора и нажмите Y для сохранения. Теперь перезапустим Apache2 :
<code bash>sudo /etc/init.d/apache2 restart</code>
  
Вы почти готовы идти дальше. Посетите: http://localhost/dokuwiki/doku.php
\\
Remember, that default configuration prevents you from visiting you dokuwiki outside localhost.

The initial DokuWiki setup is actually done when DokuWiki is installed. Если вы хотите вернуть первоначальные настройки (http://localhost/dokuwiki/install.php) вы должны сделать следующее:

<code bash>
sudo chown -R www-data /usr/share/dokuwiki/conf/
sudo rm /usr/share/dokuwiki/conf/users.auth.php
sudo rm /usr/share/dokuwiki/conf/acl.auth.php
sudo nano /usr/share/dokuwiki/install.php
</code>

Найдите следующие строки кода:
<code php>
  // main dokuwiki config file (conf/dokuwiki.php) must not have been modified
  $installation_hash = md5(preg_replace("/(\015\012)|(\015)/","\012",
                           @file_get_contents(DOKU_CONF.'dokuwiki.php')));
  if (!in_array($installation_hash, $dokuwiki_hash)) {
        $error[] = sprintf($lang['i_badhash'],$installation_hash);
        $ok = false;
    }
</code>  
Замените
<code php>$ok = false;</code>
на
<code php>$ok = true;</code>
  
Run the initial configuration with
  http://localhost/dokuwiki/install.php
  

====== Alternative Easier Custom Installation ======
The version of DokuWiki that comes with Ubuntu is generally slightly older. Installing it via the package manager also does not seem to work very well.
You can easily install the latest version by following these steps (tested on Ubuntu 9.04):

  * Make sure you have apache2 and PHP installed. If you do not have those up already, there are lots of instructions for installing them. You can test if you have Apache installed by navigating your browser to http://localhost/
  * Make sure you have the utility wget installed. Run the  Synaptic Package Manager (click System, Administration, Synaptic Package Manager) and search for wget. It is very small so it is quick to install.
  * Go to the DokuWiki downloads page and get the link for the version you want to use. It will be something like: %%http://www.splitbrain.org/_media/projects/dokuwiki/dokuwiki-2010-11-07.tgz%%

Now click Applications, Accessories, Terminal. Then enter these commands:
<code bash>
cd /var/www
sudo wget http://www.splitbrain.org/_media/projects/dokuwiki/dokuwiki-2010-11-07.tgz
sudo tar xvf dokuwiki-2010-11-07.tgz
sudo mv dokuwiki-2010-11-07 dokuwiki
sudo chown -R www-data:www-data /var/www/dokuwiki
</code>

The last line is the bit of magic that will fix the write and access permissions and make apache2 find the files. Incidentally, nearly the same recipe can be successfully used to install other Apache applications such as Joomla, Drupal, etc.
Needless to say, update the above command by changing the names slightly if you choose to download a different version of DokuWiki.

If you do not have wget, simply click in your browser to download the the DokuWiki file. Then do this:

<code bash>
cd /var/www
sudo mv /home/USER/Desktop/dokuwiki-2009-12-25c.tgz .
(Now continue on with the tar command above)
</code>

Now you should be able to navigate to http://localhost/dokuwiki/install.php

With this approach the package manager will not show DokuWiki as installed. To uninstall it again completely, do this:

<code bash>
cd /var/www
sudo rm -r -f dokuwiki
