DokuWiki

DokuWiki

DokuWiki is simple wiki software. Although there are many other wiki platforms, DokuWiki is probably the simplest one to use. It is also not too resource-hungry, unlike most other dynamic web platforms, meaning it should comfortably fit on your 512 MB RAM VPS or machine.

DokuWiki’s official website itself uses DokuWiki, and here’s what it looks like.

Installation

Nginx Configuration

Create a file named /etc/nginx/sites-available/dokuwiki using your favorite text editor and add the following lines, based on the configuration here. Remember to change wiki.example.org to your website’s name. Also, pay attention to the lines containing client_max_body_size, which determines the maximum file size allowed for uploads, and the first location line, because it needs to be commented during the installation and uncommented when it’s done.

server {
  listen 80;
  listen [::]:80;
  server_name wiki.example.org;

  # Maximum file upload size is 4MB - change accordingly if needed
  client_max_body_size 4M;
  client_body_buffer_size 128k;

  root /var/www/dokuwiki;
  index doku.php;

  #Remember to comment the below out when you're installing, and uncomment it when done.
  #location ~ /(conf/|bin/|inc/|vendor/|install.php) { deny all; }

  #Support for X-Accel-Redirect
  location ~ ^/data/ { internal ; }

  location ~ ^/lib.*\.(js|css|gif|png|ico|jpg|jpeg)$ {
    expires 365d;
  }

  location / { try_files $uri $uri/ @dokuwiki; }

  location @dokuwiki {
    # rewrites "doku.php/" out of the URLs if you set the userwrite setting to .htaccess in dokuwiki config page
    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$ {
    try_files $uri $uri/ /doku.php;
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_param REDIRECT_STATUS 200;
    fastcgi_pass unix:/var/run/php/php-fpm.sock;
    # fastcgi_pass unix:/var/run/php5-fpm.sock; #old php version
  }
}

Enable the website.

ln -s /etc/nginx/sites-available/dokuwiki /etc/nginx/sites-enabled/

Generate a SSL certificate for the subdomain.

certbot --nginx

Restart nginx and php in order for the changes to take effect.

systemctl restart nginx && systemctl restart php7.4-fpm

Finally, go to wiki.yourwebsite.com/install.php to finish the installation process. Read up the documentation in order to understand what each of those itens mean.

Once that’s done, remember to uncomment the location line on the nginx configuration file. Open /etc/nginx/sites-available/dokuwiki with a text editor and remove the “#” symbol at the beginning of the line.

#Remember to comment the below out when you're installing, and uncomment it when done.
location ~ /(conf/|bin/|inc/|vendor/|install.php) { deny all; }

Reload nginx once again for the changes to take effect.

systemctl restart nginx

Your wiki is now live! Have fun and happy hacking.
