How To Install Dokuwiki on Ubuntu 20.04 LTS

Install Dokuwiki on Ubuntu 20.04

In this tutorial, we will show you how to install Dokuwiki on Ubuntu 20.04 LTS. For those of you who didn’t know, DokuWiki is considered to be the most versatile open-source Wiki software application which is proven to meet your demanding wiki needs. Using a very familiar interface, it allows you to easily scale and optimize using many advanced features. Utilizing files instead of a database, DokuWiki is extremely flexible with the type of system it will run on (no database server required).

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step by step installation of Dokuwiki on a Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian based distribution like Linux Mint.

Install Dokuwiki on Ubuntu 20.04 LTS Focal Fossa

Step 1. First, make sure that all your system packages are up-to-date by running these following apt commands in the terminal.

sudo apt update
sudo apt upgrade

Step 2. Install the LAMP stack.

A Ubuntu 20.04 LAMP server is required. If you do not have LAMP installed, you can follow our guide here.

Step 3. Installing Dokuwiki on Ubuntu 20.04.

Now we download the latest version of DokuWiki using the following command:

cd /var/www/html
wget https://download.dokuwiki.org/src/dokuwiki/dokuwiki-stable.tgz

Unpack the Dokuwiki archive to the document root directory on your server:

tar -xvzf dokuwiki-stable.tgz
mv dokuwiki-2020-07-29 dokuwiki

We will need to change some folders permissions:

chown -R www-data:www-data /var/www/html/dokuwiki
chmod -R 775 /var/www/html/dokuwiki

Step 4. Configuring Apache web server.

Create a new virtual host directive in Apache. For example, create a new Apache configuration file named ‘dokuwiki.conf’ on your virtual server:

touch /etc/apache2/sites-available/dokuwiki.conf
ln -s /etc/apache2/sites-available/dokuwiki.conf /etc/apache2/sites-enabled/dokuwiki.conf
nano /etc/apache2/sites-available/dokuwiki.conf

Add the following lines:

<VirtualHost *:80>
ServerAdmin [email protected]
DocumentRoot /var/www/html/dokuwiki/
ServerName your-domain.com
ServerAlias www.your-domain.com
<Directory /var/www/html/dokuwiki/>
Options FollowSymLinks
AllowOverride All
Order allow,deny
allow from all
</Directory>
ErrorLog /var/log/apache2/your-domain.com-error_log
CustomLog /var/log/apache2/your-domain.com-access_log common
</VirtualHost>

Now, we can restart the Apache webserver so that the changes take place:

sudo a2enmod rewrite
sudo a2ensite dokuwiki.conf
sudo systemctl restart apache2

Step 5. Set up HTTPS.

We should enable a secure HTTPS connection on Nextcloud. We can obtain a free TLS certificate from Let’s Encrypt. Install Let’s Encrypt client (certbot) from Ubuntu 20.04 repository:

sudo apt install certbot python3-certbot-apache

Next, run the following command to obtain a free TLS certificate using the Apache plugin:

sudo certbot --apache --agree-tos --redirect --staple-ocsp --email [email protected] -d example.com

If the test is successful, reload Apache for the change to take effect:

sudo apache2ctl -t
sudo systemctl reload apache2

Step 6. Accessing DokuWiki Web Interface.

DokuWiki will be available on HTTP port 80 by default. Open your favorite browser and navigate to http://your-domain.com/install.php or http://server-ip-address/install.php and complete the required steps to finish the installation. If you are using a firewall, please open port 80 to enable access to the control panel.
