    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    sendfile        on;
    keepalive_timeout  65;
    server {
        listen       80;
        server_name  localhost;
        root         /usr/share/nginx/html;

        index index.php;

        location / {
            try_files $uri $uri/ /index.php$is_args$args;
