Nginx的fastcgi_cache不工作的一个WP网站（但工作正常time.php在不同的虚拟主机）

我运行的Ubuntu nginx 1.8与FPM PHP 5.5，在一个网站上我能够得到caching工作（与一个简单的时间输出） <?php echo time();?>显示：

 Connection:keep-alive Content-Encoding:gzip Content-Type:text/html Date:Fri, 08 Jan 2016 14:04:00 GMT Fastcgi-Cache:HIT Server:nginx/1.8.0 Transfer-Encoding:chunked X-Powered-By:PHP/5.5.9-1ubuntu4.14 

但是对于WordPress站点来说，标题总是显示（甚至在注销和隐身时）：

 Cache-Control:no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Connection:keep-alive Content-Encoding:gzip Content-Type:text/html; charset=UTF-8 Date:Fri, 08 Jan 2016 14:02:42 GMT Expires:Thu, 19 Nov 1981 08:52:00 GMT Fastcgi-Cache:BYPASS Link:<http://mywpsite.com/wp-json/>; rel="https://api.w.org/" Link:<http://mywpsite.com/>; rel=shortlink Pragma:no-cache Server:nginx/1.8.0 Transfer-Encoding:chunked Vary:Accept-Encoding X-Powered-By:PHP/5.5.9-1ubuntu4.14 

从维基我已经尝试不同的设置，并压缩到以下单个文件（tester.com工程，而mywpsite.com不 – 这些都是我已经在我的主机文件中设置的别名，并肯定击中正确的服务器） https：// codex .wordpress.org / Nginx 。

cat /etc/nginx/nginx.conf

道歉，我相信这是愚蠢的，但经过了一些深夜，会欣赏一些新鲜的眼睛在这个过程。
