如何在不杀死运行php的情况下使站点脱机进行维护从http端开始？

Question

I wrote a script upload_songs.php

When executed from the command line

$ php upload_songs.php

I can take the site offline

$ a2dissite my_website
$ service apache2 reload

and upload_songs.php will continue to run

However when I execute upload_songs.php from the http side by going to my_website.com/upload_songs.php if I do the following

$ a2dissite my_website
$ service apache2 reload

The php process upload_songs.php gets killed. How can I take the site offline for maintenance without killing running php processes that have been started from the http side?

Answer 1

apachectl graceful

This will wait until all connections are closed before restarting apache.
