sudo ln -s /etc/nginx/sites-available/wiki.sinfrontera.net /etc/nginx/sites-enabled/
sudo nginx -t
sudo systemctl reload nginx
sudo systemctl restart nginx  # Only if reload fails or Nginx behaves oddly


MySQL 

sudo apt install mysql-server
sudo systemctl start mysql
sudo systemctl status mysql

sudo mysql_secure_installation
* Use VALIDATE PASSWORD plugin? : No
* Remove anonymous users? : Yes
* Disallow root login remotely? : Yes
* Remove test database and access to it? : Yes
* Reload privilege tables now? : Yes

# Configuring the root password
sudo mysql

ALTER USER 'root'@'localhost'
IDENTIFIED WITH mysql_native_password
BY 'Enter_password_here';

FLUSH PRIVILEGES;
EXIT;

# Creating the wiki database
mysql -u root -p
CREATE DATABASE wikidb;


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


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: 

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.



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, aquí se 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



Cambiar el 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

By default, the configuration code in php.ini limits the size of files to be uploaded to 2 megabytes (and the maximum size of a post operation to 8 megabytes). To allow uploading of larger files, edit these parameters in php.ini: 

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

It is important to change the php.ini file in the apache2 folder. 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

After the change: 

sudo /etc/init.d/apache2 restart
