请大家帮忙看看下面的配置是否合理?

<code>pm = dynamic
pm.max_children = 40
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 40
 
pm.max_requests = 5000</code>
Copy after login
Copy after login

我一直以为 max_spare_servers是指定最大的空闲php进程数量,在一台机器上跑了若干个运行php环境的docker实例,如果空闲的实例也一直保持40个空闲进程,是否会导致资源利用不均衡或者其他繁忙的实例资源不足?

会! 空闲的进程不但要占着内存,而且还要占着上次请求里没有释放的内存,如果最大空闲量开得过大,很容易内存飙高而且长时间不回落(可以通过监控看到)。
建议最大空闲不要开太多,另外 pm.max_requests 可以有效降低刚才说的那种情况,5000还是比较合适的。

空闲进程不占CPU,只会占用一定的内存。
