The nginx server configuration file needed to host the MirrorMirror application

mirror.conf

server {
    listen 80;
    server_name localhost;
    root /home/pi/projects/MirrorMirror/public;
    
    index index.html index.htm index.php;
    
    charset utf-8;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }
    
    location = /favicon.ico { access_log off; log_not_found off; }
    location = /robots.txt  { access_log off; log_not_found off; }

    access_log off;
    error_log  /var/log/nginx/myapp-error.log error;

    sendfile off;

    client_max_body_size 100m;

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_intercept_errors off;
        fastcgi_buffer_size 16k;
        fastcgi_buffers 4 16k;
    }

    location ~ /\.ht {
        deny all;
    }
}

For people still getting the error "ln: target 'reload' is not a directory".
Use the command:
sudo ln -s /etc/nginx/sites-available/mirror.conf /etc/nginx/sites-enabled/mirror.conf && sudo service nginx reload
