我正在使用 docman 构建一个 Joomla 网站，用于文档管理/下载。该网站建立在运行 Nginx 1.4.2 和 PHP5 (FPM) 的 Ubuntu 14.04 服务器上。
我遇到的问题是文件下载不一致（就大小而言）。例如，我从网站下载了 6 次 PDF 文件，结果如下：
- 72 KB
- 75 KB
- 146 千字节
- 177KB（完整文件）
- 72 KB
- 177KB（完整文件）
本次测试中，6 次中有 2 次成功下载了完整文件。其余 4 次文件不完整。
我的 nginx.conf 如下所示
user www-data;
worker_processes 1;
error_log logs/error.log;
worker_rlimit_nofile 8192;
events {
worker_connections 4096;

答案1
根据日志文件解决问题...
我更改了 /var/lib/nginx/fastcgi 文件夹的权限并且它起作用了。
chown -R www-data /var/lib/nginx/fastcgi
