DokuWiki is an open-source, flat-file wiki software that doesn’t require a database. Instead, it helps you create personal or business websites in minutes by uploading their content to your server. In addition, DokuWiki wiki software offers features that may not be available to other PHP-based CMS, like WordPress, Joomla, or Drupal.
For one, it doesn’t need a database server; all its data is stored in the file system (file-based, flat file CMS). It also provides native markdown WYSIWYG support, SEO friendly, flexible CSS framework with no installation required.
Its built-in access controls and authentication connectors make DokuWiki especially useful in the enterprise and for personal use.

This brief tutorial shows students and new users how to install DokuWiki on Ubuntu 16.04 / 18.10 / 18.04 LTS with Nginx and PHP 7.2-FPM support.
When you’re ready to get DokuWiki working, continue with the steps below:
Install Nginx HTTP Server
Nginx HTTP Server is probably the second most popular web server, so install it since DokuWiki needs it.
To install Nginx HTTP on the Ubuntu server, run the commands below.
sudo apt update sudo apt install nginx
After installing Nginx, the commands below can be used to stop, start and enable the Nginx service to always start up with the server boots.
sudo systemctl stop nginx.service sudo systemctl start nginx.service sudo systemctl enable nginx.service
To test the Nginx setup, open your browser and browse to the server hostname or IP address, and you should see the Nginx default test page as shown below. When you see that, then Nginx is working as expected.
http://localhost
Install PHP 7.2-FPM and Related Modules.
PHP 7.2-FPM may not be available in Ubuntu default repositories for some systems. So you will have to get it from third-party repositories if you need it.
Run the commands below to add the below third-party repository to upgrade to PHP 7.2-FPM
sudo apt-get install software-properties-common sudo add-apt-repository ppa:ondrej/php
Then update and upgrade to PHP 7.2-FPM
sudo apt update
Next, run the commands below to install PHP 7.2 and related modules.
sudo apt install php7.2-fpm php7.2-common php7.2-mbstring php7.2-xmlrpc php7.2-sqlite3 php7.2-soap php7.2-gd php7.2-xml php7.2-cli php7.2-tidy php7.2-intl php7.2-json php7.2-curl php7.2-zip
After installing PHP 7.2, run the commands below to open Nginx’s PHP default config file.
sudo nano /etc/php/7.2/fpm/php.ini
Then save the changes on the following lines below in the file. The value below is an excellent setting to apply in your environment.
file_uploads = On allow_url_fopen = On memory_limit = 256M cgi.fix_pathinfo = 0 upload_max_filesize = 100M max_execution_time = 360 date.timezone = America/Chicago
After making the change above, please save the file and close it.
After installing PHP and related modules, you must restart Nginx to reload PHP configurations.
To restart Nginx, run the commands below
sudo systemctl restart nginx.service
Download DokuWiki Latest Release
Next, visit the DokuWiki site and download the latest package. Or run the commands below to download DokuWiki packages from GitHub.
After downloading, run the commands below to extract the downloaded file and move it into a new DokuWiki root directory. After that, change into the DokuWiki root directory to install the PHP-required packages.
Take notes of the branch number. If there are newer branch numbers, replace the one below with them.
cd /var/www/html/
sudo apt install git
sudo git clone --branch stable https://github.com/splitbrain/dokuwiki.git
Then run the commands below to set the correct permissions for DokuWiki to function correctly.
sudo chown -R www-data:www-data /var/www/html/dokuwiki/ sudo chmod -R 755 /var/www/html/dokuwiki/
Configure the Nginx DokuWiki Site
Finally, configure the Nginx configuration file for DokuWiki. This file will control how users access DokuWiki content. Run the commands below to create a new configuration file called DokuWiki.
sudo nano /etc/nginx/sites-available/dokuwiki
Then copy and paste the content below into the file and save it. Replace the highlighted line with your domain name and directory root location.
server {
listen 80;
listen [::]:80;
root /var/www/html/dokuwiki;
index index.php index.html index.htm;
server_name example.com www.example.com;
client_max_body_size 100M;
location / {
try_files $uri $uri/ @dokuwiki;
}
location @dokuwiki {
rewrite ^/_media/(.*) /lib/exe/fetch.php?media=$1 last;
rewrite ^/_detail/(.*) /lib/exe/detail.php?media=$1 last;
rewrite ^/_export/([^/]+)/(.*) /doku.php?do=export_$1&id=$2 last;
rewrite ^/(.*) /doku.php?id=$1&$args last;
}
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
Save the file and exit.
After configuring the VirtualHost above, please enable it by running the commands below.
Enable the DokuWiki Site and Rewrite Module
After configuring the VirtualHost above, please enable it by running the commands below, then restart the Nginx server.
sudo ln -s /etc/nginx/sites-available/dokuwiki /etc/nginx/sites-enabled/
Restart Nginx
sudo systemctl restart nginx.service
Next, open your browser and browse to the server hostname or IP address, and you should see the DokuWiki page setup page.
http://http://example.com/install.php
DokuWiki is a database-less flat file content management system. Its structure allowed you to have just the amount of functionality needed in a flat file CMS solution, adding extensions (blade packs) for additional functionality while allowing setup on simple servers with no database.
You should be able to log on with the username and password you created.
Enjoy!
