Answer a question

I'm deploying a Django application online using AWS Elastic Beanstalk. It worked fine for a while, but some change is causing the application to throw a '413 Request Entity Too Large nginx/1.18.0' error when I try to upload a file.

Here are my logs:

      client_max_body_size "100M";

I read many posts that fixed the same problem by including creating a file to change the max file size to something larger, which i tried at the end of the config file. But, it did not work. If there is any more information I can provide, I would be happy too! Thank you in advance :)

The nginx setting you are trying to use (/etc/nginx/conf.d/proxy.conf) is for Amazon Linux 1.

Since you are probably using Amazon Linux 2 you should be using different files for customizing nginx. For AL2, the nginx settings should be in .platform/nginx/conf.d/, not in .ebextentions as shown in the docs.

Therefore, you could have the following .platform/nginx/conf.d/myconfig.conf with content:

client_max_body_size 100M;
# python # django # nginx

问题:MySQL远程时缓存如何工作? 我一直在使用 PHP 5.6 进行旧电子商务应用程序的服务器迁移。 切换涉及来自 Linode 的两台 Dedicated 32 服务器。 一台服务器用于 NginX + PHP,另一台仅用于 MySQL。 遗留应用程序利用 memcached。 切换后,我可以看到由于私有入站和出站连接导致的大量内部流量。 到目前为止,这个元素没有对性能造成任何问题。 但是,
