server {
listen 80;
server_name mysite.com;
root /var/www/mysite.com/;

location / {
if (-f $document_root/maintenance.html) {
return 503;
}
… # the rest of your config goes here
}

error_page 503 @maintenance;
location @maintenance {
rewrite ^(.*)$ /maintenance.html break;
}
}

Now whenever you need to take your site offline, simply create the file maintenance.html in the $document_root (in our case, /var/www/mysite.com). If the file exists, Nginx will serve it with a 503 status code, if not, it will proceed as usual.
