Steps to Install Dokuwiki on Ubuntu 20.04 LTS Focal Fossa

1.  Perform System Update

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

$ sudo apt update
$ sudo apt upgrade

2. Install  LAMP stack

If you do not have LAMP installed, you can follow our guide here.

3. Install Dokuwiki on the system

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

$ cd /var/www/html
$ wget

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

4. Configure Apache webserver

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>
DocumentRoot /var/www/html/dokuwiki/
<Directory /var/www/html/dokuwiki/>
Options FollowSymLinks
AllowOverride All
Order allow,deny
allow from all
ErrorLog /var/log/apache2/
CustomLog /var/log/apache2/ common

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

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

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 -d

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

$ sudo apache2ctl -t
$ sudo systemctl reload apache2
