我在AWS Beanstalk中设置了一个反向代理。 nginx的目的是从上游Location标头中获取一个值,并将结果与原始请求URI的缓存键一起存储,以便将来的客户端也无需遵循重定向。
此处的磁盘空间最多为68G:/ var / nginx / cache,此处为30G:/ var / nginx / temp-cache。因此,我的代理服务器的磁盘空间很快就满了。
任何人都知道如何减少或限制缓存的大小吗?还是如果有一种更有效的更好的方法来使我的磁盘填满的速度不那么快?谢谢。

在过去的几周中,我通过测试几个模块找到了解决方案。看起来可行并减少缓存大小的方法是使用以下模块:
proxy_max_temp_file_size 1024m;
proxy_buffer_size 4k;
proxy_buffers 4 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;
