![CentOS,Nginx - 缓存文件夹为空](https://linux22.com/image/704115/CentOS%EF%BC%8CNginx%20-%20%E7%BC%93%E5%AD%98%E6%96%87%E4%BB%B6%E5%A4%B9%E4%B8%BA%E7%A9%BA.png)
我已经在 DigitalOcean 上的 CentOS7.2 上设置了 nginx 网络服务器(单个站点)。
按照一些操作指南,我成功设置了 nginx 和缓存,但尽管反复访问我的网站,我的缓存文件夹仍然是空的。
没有报告错误并且其他一切正常。
nginc.conf如下:

请帮我理解我可能遗漏了什么。我正在尝试将 TTFB 缩短至 100 毫秒以下(目前为 420 毫秒)
提前致谢!

看起来它运行良好。
测试我的网站页面得到以下结果,因此造成混淆。
curl -I https://www.31west.net
HTTP/1.1 200 OK
Server: nginx/1.10.2
Date: Fri, 12 May 2017 12:05:25 GMT
Content-Type: text/html; charset=utf-8
Connection: keep-alive
Vary: Accept-Encoding
X-Powered-By: PHP/5.4.16
X-XSS-Protection: 0
Set-Cookie: PHPSESSID=d4vsle1tbersa504vpfr058ln7; path=/
Expires: Thu, 19 Nov 1981 08:52:00 GMT
Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre- check=0
Pragma: no-cache
X-Fastcgi-Cache: MISS
使用小型演示页面进行测试得出以下结果。
curl -I https://www.31west.net/a.php
HTTP/1.1 200 OK
Server: nginx/1.10.2
Date: Fri, 12 May 2017 12:17:25 GMT
Content-Type: text/html
Connection: keep-alive
Vary: Accept-Encoding
X-Powered-By: PHP/5.4.16
X-Fastcgi-Cache: HIT
但即使只有 10 字节测试页面和上述 nginx 配置,托管在 2 GB RAM、2 核处理器硬件的 DO 上,我的 TTFB 也为 430 毫秒
我已经用尽所有可能的配置来改进它。
任何建议都将不胜感激。
