如何知道PHP上设置了多少个子服务器和服务器

Question

我今天意识到一个大问题，太多的流量使我的网站完全瘫痪，但我有一个大服务器来主持它。我得到的是：

[20-May-2019 14:23:02] WARNING: [pool www] seems busy (you may need to increase pm.start_servers, or pm.min/max_spare_servers), spawning 8 children, there are 4 idle, and 22 total children
[20-May-2019 14:23:03] WARNING: [pool www] seems busy (you may need to increase pm.start_servers, or pm.min/max_spare_servers), spawning 16 children, there are 3 idle, and 30 total children
[20-May-2019 14:23:04] WARNING: [pool www] seems busy (you may need to increase pm.start_servers, or pm.min/max_spare_servers), spawning 32 children, there are 0 idle, and 42 total children
[20-May-2019 14:23:05] WARNING: [pool www] seems busy (you may need to increase pm.start_servers, or pm.min/max_spare_servers), spawning 32 children, there are 0 idle, and 57 total children
[20-May-2019 14:23:06] WARNING: [pool www] seems busy (you may need to increase pm.start_servers, or pm.min/max_spare_servers), spawning 32 children, there are 0 idle, and 72 total children
[20-May-2019 14:23:07] WARNING: [pool www] seems busy (you may need to increase pm.start_servers, or pm.min/max_spare_servers), spawning 32 children, there are 0 idle, and 87 total children
[20-May-2019 14:23:08] WARNING: [pool www] seems busy (you may need to increase pm.start_servers, or pm.min/max_spare_servers), spawning 32 children, there are 0 idle, and 102 total children
[20-May-2019 14:23:09] WARNING: [pool www] seems busy (you may need to increase pm.start_servers, or pm.min/max_spare_servers), spawning 32 children, there are 0 idle, and 117 total children
[20-May-2019 14:23:10] WARNING: [pool www] seems busy (you may need to increase pm.start_servers, or pm.min/max_spare_servers), spawning 32 children, there are 9 idle, and 132 total children

但是我认为我已经用这个配置在我的fpm上配置了足够多的子程序：

• pm.max_children = 100
• pm.start_servers = 15
• pm.min_spare_servers = 15
• pm.max_spare_servers = 25

但我犯了个错误。你知道我可以设置多少来接收更多的流量吗？我有32 of的RAM和8核

该日志文件意味着110个进程在8秒内启动。注意，它快速地连续启动了32的多个批。pm.min_spare_servers = 15将无法吸收这样的连接增加，响应时间将是可怕的。

保持足够多的空闲进程来吸收最大的连接峰值，并且最大值在此之上。当然，如果您有足够的内存和CPU。试着做这样的事情：

pm.max_children = 500
pm.min_spare_servers = 100
pm.max_spare_servers = 200

继续将其作为能力规划过程的一部分进行调优。例如，您可能有更多的资源来增加。或者，您可能不需要更多的php-fpm，而资源将更好地用于主机上的其他工作负载。

也谈服务器故障：警告:池似乎很忙(您可能需要增加pm.start_服务器，或pm.min/max_备用_(服务器)
