PagesPeed无法阅读缓存清洁时间戳/var/cache/pagespeed/！clean！time！。进行额外的缓存以安全

Question

偶然发现了在云运行中托管的无状态码头容器的nginx pagespeed上的以下错误。在本地测试时，部署后我不会收到错误，几乎每个请求后都会记录错误。

如您所见，几乎每个请求后都记录了该错误。...一切都起作用了，但是该日志很烦人，意味着某些事情不正确。

问题

运行NGINX的用户无法写入这些目录的

。 配置引起错误。

pagespeed FileCachePath "/var/cache/pagespeed/";
pagespeed CreateSharedMemoryMetadataCache "/var/cache/pagespeed/" 102400;

解决方案

• 创建目录v3
• Create Directory SHM_METADATA_CACHE
• Create File clean clean！time！

...

RUN mkdir -p /var/cache/pagespeed/shm_metadata_cache && mkdir -p /var/cache/pagespeed/v3 && touch /var/cache/pagespeed/!clean!time!
...

授予目录和文件的所有权限

...

RUN chmod 777 /var/cache/pagespeed/shm_metadata_cache && chmod 777 /var/cache/pagespeed/v3 && chmod 777 /var/cache/pagespeed/!clean!time!
...
