1. Create users.json based on users.dist.json and make it writable by PHP
2. Make the folder sessions writable by PHP
3. The web server should target the folder www

server {
  root /path/to/soccer-session/www;
  server_name soccer-session.com;

  location / {
    index index.php;
  }

  error_page 404 /404.html;

  location ~ .php$ {
    fastcgi_pass 127.0.0.1:9000;
    fastcgi_index index.php;
    include /etc/nginx/fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name;
  }
}

A user has an identifier and a name. And the identifier is unique.

The file users.json represents a key-value dictionary. The key is the user identifier and the value is the user properties.

To create an administrator, you must set the type property of the user to admin.

Example:

{
  "1234": {
    "name": "John Doe",
    "type": "admin"
  },
  "5678": {
    "name": "Sarah Croche"
  }
}
