These are instructions on how to install a single DokuWiki under Ubuntu 14.04. Other version installations are discussed below. If you want to install a DokuWiki Farm, follow these instructions and then visit the Farm Page.

For Ubuntu 16.04 you will want to use libapache2-mod-php7.0 and make sure to install php7.0-xml, php7.0 with apt-get

Upgrading from Ubuntu 14.04 LTS to Ubuntu 16.04 LTS I had to add the following:

• apt-get install php7.0
• apt-get install php-mbstring
• apt-get install php7.0-xml

This resolved all the issues restoring Dokuwiki back to normal prior to the upgrades.

1. Install Ubuntu Server 14.04 Step by step instructions with screenshots
2. Update & Upgrade Ubuntu.

   sudo apt-get update && sudo apt-get upgrade

3. Install Apache2 and PHP.

   sudo apt-get install apache2 libapache2-mod-php php-xml

4. Enable Apache Rewrite module.

   sudo a2enmod rewrite

5. Download and uncompress the latest stable release.

   cd /var/www
   sudo wget https://download.dokuwiki.org/src/dokuwiki/dokuwiki-stable.tgz
   sudo tar xvf dokuwiki-stable.tgz
   sudo mv dokuwiki-*/ dokuwiki

6. Change permissions.

   sudo chown -R www-data:www-data /var/www/dokuwiki

7. Change document root in Apache to point to /var/www/dokuwiki

   sudo nano /etc/apache2/sites-enabled/000*.conf

   Replace
   DocumentRoot /var/www/html
   with
   DocumentRoot /var/www/dokuwiki

   1. If you want to host a DokuWiki server on localhost for testing purposes do NOT change the content of /etc/apache2/sites-enabled/000*.conf, instead create a new file in
      /etc/apache2/sites-available
      with

      sudo touch apache2-dokuwiki.conf

      with the following content:

      <VirtualHost 127.0.0.1>
              DocumentRoot /var/www/dokuwiki
       	ServerName localhost
      </VirtualHost>

   2. enable the new project by placing it into /etc/apache2/sites-enabled with

      sudo a2ensite apache2-dokuwiki

   3. and then reload apache2 service

      sudo service apache2 reload

8. Change AllowOverrides setting in Apache2 to use .htaccess files for security.

   sudo nano /etc/apache2/apache2.conf

   1. For directory /var/www/ replace
      AllowOverride None
      with
      AllowOverride All
9. Restart Apache2 service.

   sudo service apache2 restart

10. Visit http://IP-address-of-your-server/install.php to initially configure your DokuWiki.
    1. If you decided to host DokuWiki on localhost for testing purposes from point 7a-c, visit 127.0.0.1/install.php
11. Delete the install.php file after finished installing.

    sudo rm /var/www/dokuwiki/install.php

12. Needed for sending email (e.g. user registration): install sendmail program, e.g. postfix

    sudo apt-get install postfix

    and configure appropriately

13. Enjoy your own DokuWiki server.

For more information on installing and configuring Dokuwiki on Ubuntu, see debian_ubuntu_extras.

This works with Ubuntu 11.04 natty:

1. Install apache2 and the php5 module:

   sudo apt-get install apache2 libapache2-mod-php5

2. Enable the userdir and rewrite modules:

   sudo a2enmod userdir
   sudo a2enmod rewrite

3. To make your .htaccess work, edit /etc/apache2/mods-enabled/userdir.conf and change the AllowOverride directive to All¹⁾
4. By default, php is disabled for user directories. To enable it, comment the lines as per instruction in /etc/apache2/mods-enabled/php5.conf
5. Restart apache with

   sudo service apache2 restart

1. Install lighttpd and php.

   sudo apt-get install lighttpd 
   sudo apt-get install php5-cgi 

2. Download dokuwiki, and place in www directory. Change file name appropriately as your downloaded file is placed and named.

   tar xvfz dokuwiki.tgz 
   ls -l
   sudo cp -r dokuwiki/ /var/www/
   sudo chown -R www-data:www-data /var/www/dokuwiki

3. Configure lighttpd for php.

   sudo lighttpd-enable-mod fastcgi-php
   sudo /etc/init.d/lighttpd force-reload

4. That's it. Enjoy your own DokuWiki server. (Test if it works on your http://localhost/dokuwiki)
