Nginx 文件上传在中间暂停/停止（仅上传 258kb 并停止）-408 请求超时

Question

我已经安装了 bitnami nginx 堆栈（nginx、php-fpm、mysql）来运行多个 drupal 7 和 node.js 站点，但目前只安装了一个 D7 站点。

文件上传在本地主机上完美运行。但是，当我使用 bitnami nginx 堆栈将其上传到 Linode vps 时，它开始显示上传问题。

对于较小的文件（~60kb），上传工作正常。但对于较大的文件，上传会停止。少数情况：563KB 文件 - 上传在 46% 处停止 3.5MB 文件 - 在 ~7% 处停止

POST 的访问日志如下所示（给出 408）：

x.x.x.x - - [07/Sep/2014:20:15:24 +0530] "POST /node/add/profile HTTP/1.1" 408 0 "http://mysite[dot]com/node/add/profile" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.94 Safari/537.36"

我尝试了 nginx.conf 文件中所有我能尝试的方法，但没有任何帮助。

更新：未使用 Drupal 进行测试，仅使用一个简单的 PHP 脚本 - 同样的故障。肯定与 nginx/php-fpm 有关！

更新 2：关闭 php-fpm 并仅使用带有上传字段的 html 页面进行测试。同样的问题 - 肯定是 nginx 或 bitnami！

Answer 1

您的 client_max_body_size 超出了服务器定义。将其置于服务器定义内会产生什么结果？

此外，@PratapSingh 还提出了另一个好问题 - php.ini 中的 max_upload_filesize 限制是多少？
