我有一个很大的社交媒体页面，我在那里发布我网站文章的链接，这意味着我每天分享东西时都会有很多流量高峰。最近，我注意到该网站速度太慢，有时根本无法加载。不幸的是，我对解决此类问题不太熟悉，而且我没有一位系统管理员来管理我的专用服务器，因为我是从OVH租来的，OVH提供低成本的非托管服务器。服务器有很好的规格，即使站点上有100个活动用户，这个问题也会发生。我还可以在服务器日志中看到一些错误

服务器规格如下所示：

AMD Opteron（tm）处理器4334，AMD Opteron（tm）处理器4334（6核）

SoftRaid 3x160GB SSD

32GB内存

1Gbps连接

关于快速CGI_参数-我不知道在Plesk的哪里可以找到这个。我只能找到一个包含我不知道其值的变量的文件。例如，如以下几行（整个文件就是这样的）：

我很抱歉，如果有什么遗漏，我真的试图使它尽可能详细，它也不容易找到配置文件的位置与普莱斯克。我必须对上面所附的每个文件做一些研究。。。（老实说，这是我不喜欢普莱斯克的原因之一，但这正是我所拥有的）

如果您还有任何配置文件需要我发送，请让我知道，我将在评论中附上它。还请告诉我在哪里可以找到它们（考虑到我使用的是Plesk v12.5）。对我来说，根据我的需要和规格正确配置服务器并消除错误非常重要，因此请帮助我。：）

谢谢大家!

尝试增加php fpm子项的数量，例如：

pm.max_children = 30
pm.start_servers = 10
pm.min_spare_servers = 3
pm.max_spare_servers = 15

那么突然的流量峰值不会产生错误

我也有这个问题。重新启动fpm修复了它

sudo服务php7.1-fpm重启

更改php版本。

您确定吗？是的，这降低了出错的几率，但它们会突然消失吗？如果我将您的服务器置于非常高的负载下，您的解决方案是否仍然有效？也，OP询问将配置放置在何处这取决于服务器CPU，需要进行测试。当然，大型pm.max_子项会增加CPU消耗。参数转到/etc/php fpm.d/####。conf解释了如何根据应用程序的需要和服务器规格确定正确的max#子项数量，而有时什么都不起作用重新启动服务可能会起作用。但这不是正确的解决方案。一个人应该找到问题的根本原因并解决它。为我工作的所有其他解决方案都失败了，在生产中不是一个可接受的解决方案。
