当用户中止请求时，如何使PHP-FPM进程终止? (Nginx) [英] How do I get the PHP-FPM process to terminate when a user aborts request? (Nginx)

问题描述

我知道Nginx与PHP-FPM进程无关，但是我更希望如果用户中止而导致PHP-FPM进程死亡，那么它就不会继续做不必要的事情或浪费资源.对于PHP-FPM/Nginx，无论用户是否中止，trigger_error都会发生:

I know Nginx has nothing to do with the PHP-FPM process, but I would much prefer if the PHP-FPM process died if a user aborts so it doesn't continue doing needless things or wasting resources. For PHP-FPM/Nginx the trigger_error will happen regardless of user abort:

<?php

sleep(30);
trigger_error('Still happened?');

?>

如何使用户中止PHP-FPM? (如果可能的话)

How can I do user aborts for PHP-FPM? (if possible)

推荐答案

php-fpm未实现，更多信息

This is not implemented by php-fpm, more info here.

设置ignore_user_abort(FALSE)仅在PHP通过套接字发送数据时有效，而在忙于计算响应时则无效.

Setting ignore_user_abort(FALSE) only works when PHP sends data over the socket, not when it is busy calculating a response.

理想情况下，它应该在php-fpm中实现，但是鉴于PHP主要是单线程的，所以我认为这并不容易.

Ideally, it should be implemented in php-fpm, but I don't think it will be very easy, given that PHP is mostly single threaded.

在紧急情况下，您可以使用断开的连接杀死所有php-fpm进程.假设您有php-fpm在localhost:9000上侦听，这将起作用:

In emergency situations, you could kill all php-fpm processes with a broken connection. Assuming you have php-fpm listening on localhost:9000, this would work:

netstat -ntp | grep 127.0.0.1:9000 | grep php-fpm | grep CLOSE_WAIT |\
awk ' { print $7; } ' | cut -d/ -f1 | while read pid; do
    echo "Killing php-fpm/$pid because client has closed connection"
    kill $pid
done
