问题描述

在php中，如何获取当前可用的apache子代数
(apache记分牌中的status = SERVER_READY)?

In php, how can I get the number of apache children that are currently available
(status = SERVER_READY in the apache scoreboard)?

我真的希望我有一种简单的方法可以在php中做到这一点，

I'm really hoping there is a simple way to do this in php that I am missing.

推荐答案

您可以执行ps aux | grep httpd或ps aux | grep apache的shell命令并计算输出中的行数.

You could execute a shell command of ps aux | grep httpd or ps aux | grep apache and count the number of lines in the output.

exec('ps aux | grep apache', $output);
$processes = count($output);

我不确定状态列中的哪个状态表示已准备好接受连接，但是您可以对此进行过滤以获取准备就绪的进程数.

I'm not sure which status in the status column indicates that it's ready to accept a connection, but you can filter against that to get a count of ready processes.
