OSQA apache 内存占用

发布于 2024-09-30 04:03:11 字数 540 浏览 12 评论 0原文

我有一个 OSQA（python / django q&a 应用程序）安装，为 8 个不同的站点提供服务。这些网站都在开发中，流量很少。该服务器是具有 512 MB RAM 的虚拟专用服务器。

Apache 仅在 Nginx 后面使用 mod_wsgi 提供动态页面。我无法阻止 Apache 每个请求消耗越来越多的内存，直到服务器崩溃。

我尝试了配置参数，但没有成功地最大限度地减少内存占用。使用 apache2.conf 中的以下 mpm_prefork 参数：

StartServers          2
MinSpareServers       1
MaxSpareServers       4
MaxClients            4
MaxRequestsPerChild 100

2 个 apache 进程开始使用 4 mb，在第一个请求之后，有 4 个进程，每个进程接近 50 mb，并且随着每个新请求，这 4 个进程稳步攀升至每个进程接近 200 mb。

我感觉有什么不对劲的事情发生了。非常感谢任何建议。

I have an OSQA (python / django q&a application) installation serving 8 different sites. The sites are all in development, receiving minimal traffic. The server is a virtual private server with 512 mb of ram.

Apache is only serving dynamic pages with mod_wsgi behind Nginx. I can't stop Apache consuming more and more memory with each request until the server chokes.

I experimented with the configuration parameters without much luck to minimize the memory footprint. With the following mpm_prefork parameters in apache2.conf:

StartServers          2
MinSpareServers       1
MaxSpareServers       4
MaxClients            4
MaxRequestsPerChild 100

2 apache processes start using 4 mb and after the first request there are 4 processes with each nearly 50 mb and with each new request those 4 processes climb steadily up to nearly 200 mb each.

I feel like there is something wrong going on. Any suggestions are greatly appreciated.

运行 httperf 来对抗它，并发点击数为 10,000，结果仍然存在。

Ran httperf against this with 10,000 concurrent hits and it was still standing.
