NGINX 不缓存内容

我希望有人能给我一点启发，因为我被困在黑暗中:-P

基本上，我正在尝试制作一个反向代理 NGINX 缓存内容。反向代理工作正常，但缓存部分……不行。我遵循了许多指南和不同的方法，但都导致我的缓存文件夹为空，并且在每个

curl-X 获取-I资源返回X-代理缓存：MISS

正如我所说，我的设置非常简单，我有一个运行 Apache 和 Tomcat 的后端服务器，以及一个运行 NGINX 反向代理所有请求的前端。

我只发布一个特定（也是最简单的） nginx 虚拟主机的信息，该主机用于 Owncloud 安装。

旧帖子，..但我想更新它-

最终是 SELinux 阻止了 nginx 进程写入 /etc/nginx/cache。快速查看 /var/log/messages 发现了这个问题，安装了 setroubleshoot-server 后，它为我提供了允许写入的正确命令。
