How To Install DokuWiki on Debian 11

Install DokuWiki on Debian 11

In this tutorial, we will show you how to install DokuWiki on Debian 11. For those of you who didn’t know, DokuWiki is a free open source wiki application written completely in the PHP programming language and often deployed in Linux under the LAMP stack. It offers very useful features such as multiple language support, SEO, authentication, spam blacklist, autosave, read-only pages, simple and lightweight architecture, and more.

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 the DokuWiki on a Debian 11 (Bullseye).

Install DokuWiki on Debian 11 Bullseye

Step 1. Before we install any software, it’s important to make sure your system is up to date by running the following apt commands in the terminal:

sudo apt update
sudo apt upgrade

Step 2. Installing the LAMP stack.

A Debian 11 LAMP server is required. If you do not have LAMP installed, Please read our previous tutorial to install LAMP Server on Debian 11.

Step 3. Installing DokuWiki on Debian 11.

Now we download the latest version of DokuWiki from the official page using wget command:

wget https://download.dokuwiki.org/src/dokuwiki/dokuwiki-stable.tgz

Next, extract the downloaded file using the below command:

mkdir /var/www/html/dokuwiki
tar -xvzf dokuwiki-stable.tgz -C /var/www/html/dokuwiki/ --strip-components=1

Then, copy some necessary files using the following command:

cp /var/www/html/dokuwiki/.htaccess{.dist,}

We will need to change some folder permissions:

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

Step 4. Configure Apache Virtual Host for DokuWiki.

Now we create an Apache virtual host configuration file to host DokuWiki:

nano /etc/apache2/sites-available/dokuwiki.conf

Add the following lines:

<VirtualHost *:80>
        ServerName    dokuwiki.your-domain.com      
        DocumentRoot  /var/www/html/dokuwiki

        <Directory ~ "/var/www/html/dokuwiki/(bin/|conf/|data/|inc/)">
            <IfModule mod_authz_core.c>
                AllowOverride All
                Require all denied
            </IfModule>
            <IfModule !mod_authz_core.c>
                Order allow,deny
                Deny from all
            </IfModule>
        </Directory>

        ErrorLog   /var/log/apache2/dokuwiki_error.log
        CustomLog  /var/log/apache2/dokuwiki_access.log combined
</VirtualHost>

Save and close, then restart the Apache webserver so that the changes take place:

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

Step 5. Configure DokuWiki with Let’s Encrypt SSL.

First, install Certbot to your Debian system using the following command below:

sudo apt install certbot python3-certbot-apache

Once the Certbot client has been installed successfully, run the following command below to install the Let’s Encrypt SSL:

certbot --apache -d dokuwiki.your-domain.com

You will then be prompted to enter an email address for the certificate. After you have entered that you must agree to the T&C’s and decide if you want to share your email address with the Electronic Frontier Foundation.

Output:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Congratulations! You have successfully enabled https://dokuwiki.your-domain.com

You should test your configuration at:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

IMPORTANT NOTES:
 - Congratulations! Your certificate and chain have been saved at:
   /etc/letsencrypt/live/dokuwiki.your-domain.com/fullchain.pem
   Your key file has been saved at:
   /etc/letsencrypt/live/dokuwiki.your-domain.com/privkey.pem
   Your cert will expire on 2021-01-25. To obtain a new or tweaked
   version of this certificate in the future, simply run certbot again
   with the "certonly" option. To non-interactively renew *all* of
   your certificates, run "certbot renew"
 - If you like Certbot, please consider supporting our work by:

   Donating to ISRG / Let's Encrypt:   https://letsencrypt.org/donate
   Donating to EFF:                    https://eff.org/donate-le

Next, we set up a cron job to auto-renew the SSL certificate:

certbot renew --dry-run

You can set up a cron job to auto-renew SSL certificate every day at 12:00 AM by editing the following file:

crontab -e

Add the following line:

00 12 * * *   root /usr/bin/certbot renew >/dev/null 2>&1

Step 6. Accessing DokuWiki Web Interface.

Once successfully installed, open your web browser and type the URL https://dokuwiki.your-domian.com/install.php. You should see the DokuWiki installation screen:
