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. Test.

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

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-php5

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.

Ubuntu provides a dokuwiki package.

The package will install three categories of files:

• immutable files in /usr/share/dokuwiki
• configuration files in /etc/dokuwiki
• data files and plugins in /var/lib/dokuwiki

Install it. I used Ubuntu 12.04.5.

sudo apt-get install -y dokuwiki

This will prompt you for which webserver to use, Apache 2 or lighttpd. Pick one. It will also prompt you for the admin password. Choose one and enter it.

If you're lucky, installation is done, and you can start using DokuWiki at http://localhost/dokuwiki.

If not, you will need to make further changes to your webserver configuration. I used Apache 2, and what the package does is add a symlink

/etc/apache2/conf.d/dokuwiki.conf -> /etc/dokuwiki/apache.conf

that maps the http://localhost/dokuwiki* URL space to DokuWiki and grants access only to localhost. I edited the file to provide wider access and also had to edit rewrite rules elsewhere in my Apache configuration that counteracted this.

After that, I could log in as admin and edit pages.

Note that running http://localhost/dokuwiki/install.php will report permission errors on directories that don't actually exist.

This is harmless - it is just install.php not being smart enough to detect that the directories in question are located elsewhere. You don't actually need to run install.php or fix these things like the text below suggests.

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)
