Download the MediaWiki software from the official download page: https://www.mediawiki.org/wiki/Download and extract it at
[Note that /var/www/ will exist only if Apache is installed]

cd /var/www/sinfronteras/mediawiki

Apache

sudo apt update
sudo apt install apache2

sudo systemctl status apache2  # Check that Apache is running
sudo systemctl start apache2   # If it is not running, start it

# Configure the port Apache will listen to and the DocumentRoot
sudo vi /etc/apache2/ports.conf
Listen 8082  # Port 80 will be used by Nginix

sudo vi /etc/apache2/sites-available/000-default.conf
<VirtualHost *:8082>  # We set 8082 as the default port. Then we'll configure Nginx so we can access Apache-served sites from port 80
DocumentRoot /var/www/sinfronteras

sudo vi /etc/apache2/sites-available/wiki.sinfrontera.net.conf

Adding HTTPS with Let’s Encrypt

sudo certbot --nginx -d wiki.sinfrontera.net -d www.wiki.sinfrontera.net

# The following is not mandatory. It is only to ensure everything is ok so the certificate will renew:
sudo certbot renew --dry-run
systemctl list-timers | grep certbot   # This should display something like "certbot.timer

Nginx

sudo apt install nginx -y
sudo systemctl start nginx
sudo systemctl enable nginx
sudo systemctl status nginx

sudo rm /etc/nginx/sites-enabled/default  # If nothing has already been configured on "default"

sudo vi /etc/nginx/sites-available/wiki.sinfrontera.net

sudo nginx -t
sudo systemctl reload nginx
sudo systemctl restart nginx  # Only if reload fails or Nginx behaves oddly

sudo systemctl start mysql
sudo systemctl status mysql

PHP

sudo apt install php libapache2-mod-php
php -v

sudo apt install php-cli php-common php-mysql php-curl php-xml php-mbstring php-zip php-gd
sudo apt install php-intl php-apcu

sudo systemctl restart apache2

Tamaño máximo de los archivos cargados en el wiki https://www.mediawiki.org/wiki/Manual:Configuring_file_uploads/fr#Set_maximum_size_for_file_uploads

If you are using mod_php (most common), the most likely locations for the correct php.ini file are:

/etc/php/8.0/apache2/php.ini
/etc/php5/apache2/php.ini 

post_max_size = 8M        # I've modified it to be 50M
upload_max_filesize = 2M  # 50M

Run the MediaWiki configuration script https://www.mediawiki.org/wiki/Manual:Config_script

From the web browser

• Open a web browser and browse to the website address or path that you configured for MediaWiki and follow the instructions on the pages to connect to the database, create the MediaWiki administrator account, and to set further settings.
• After the configuration script has finished, download the generated configuration file LocalSettings.php and place the file in the base directory of your MediaWiki installation.

From Command-line:

• Creates a new LocalSettings.php using CLI parameters. See https://www.mediawiki.org/wiki/Manual:Install.php
• Uses an existing LocalSettings.php file to retrieve configuration. See https://www.mediawiki.org/wiki/Manual:InstallPreConfigured.php

php maintenance/run.php installPreConfigured [OPTION]...

# Create users
php maintenance/run.php createAndPromote Nombre_del_usuario Clave_del_usuario --sysop --bureaucrat --interface-admin

Allow image uploading

sudo chown -R www-data:www-data images  # This is the images dir in the MediaWiki dir
sudo chmod -R 755 images

Logo and FavIcon

Place the images at the following location and update LocalSettings.php

$wgLogos = [
    '1x' => "$wgResourceBasePath/resources/assets/sinfronteras_logo_white_1.png",
    'icon' => "$wgResourceBasePath/resources/assets/sinfronteras_logo_white_1.png",
];
$wgFavicon = "$wgScriptPath/resources/assets/sinfronteras_favicon_blue.png";  # It must be 48x48 pixels

Finally, configure LocalSettings.php to match your preferences and include extensions.

Configurations

Rewrites the URL and hide the index.php file from the page URL

Luego de instalar MediaWiki, la URL de mis páginas era: http://wiki.sinfronteras.ws/index.php/Python. El index.php no es apropiado. Esta url se puede rewrite de la forma explicada aquí: https://www.mediawiki.org/wiki/Manual:Short_URL. Sin embargo, vamos a aborda un método más simple usando Nginx.

Mi idea era configurar las url de esta forma: http://wiki.sinfronteras.ws/Python. Sin embargo en https://www.mediawiki.org/wiki/Manual:Short_URL se explica que esta configuración no es la más apropiada. Ver: https://www.mediawiki.org/wiki/Manual:Short_URL#URL_like_subdomain https://www.mediawiki.org/wiki/Manual:Wiki_in_site_root_directory

Se recomienda entonces colocar alguna palagra en la ruta. Por ejemplo: http://wiki.sinfronteras.ws/view/Python

sudo vi /etc/nginx/sites-available/wiki.sinfrontera.net

server {
    listen 80;
    server_name wiki.sinfrontera.net www.wiki.sinfrontera.net;
    
    client_max_body_size 50M;  # Maximum file size loaded from MediaWiki

    # Short URLs: /view/Page instead of /index.php?title=Page
    location ^~ /view/ {
        rewrite ^/view/(.*)$ /index.php?title=$1 last;
    }

    # Proxy everything to Apache
    location / {
        proxy_pass http://127.0.0.1:8082;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

vi LocalSettings.php

$wgScriptPath = "";
$wgServer = "http://wiki.sinfrontera.net";
$wgArticlePath = "/view/$1";
$wgUsePathInfo = true;

sudo nginx -t
sudo systemctl reload nginx
