为什么nginx不缓存我的内容？

Question

我检查了缓存路径/ usr/local/nginx/proxy_cache.我多次访问一些网址后找不到缓存文件.

我的配置:ngnix.conf

http {
   include       /etc/nginx/mime.types;

   default_type  application/octet-stream;

   access_log   /var/log/nginx/access.log;

   sendfile        on;
   #tcp_nopush     on;

   #keepalive_timeout  0;
   keepalive_timeout  65;
   tcp_nodelay        on;

   client_body_buffer_size  512k;  


   proxy_temp_file_write_size 128k;  
   proxy_temp_path   /usr/local/nginx/proxy_temp;  
   proxy_cache_path /usr/local/nginx/proxy_cache levels=1:2 keys_zone=content:20m inactive=1d max_size=100m;   

   gzip  on;

   include /etc/nginx/conf.d/*.conf;
   include /etc/nginx/sites-enabled/*;
}

默认

server {
listen   80;
server_name  208.115.202.87;


   location  /test {    
     proxy_cache content; 
     proxy_cache_key $host$uri$is_args$args;
         proxy_cache_valid  200 15m;
     proxy_pass  http://aaa.com/;
    }

Answer 1

nginx不会缓存设置cookie的页面,检查您的页面是否有Set-Cookie标题.

如有必要,可以使用proxy_ignore_headers忽略cookie,并使用proxy_hide_header抑制cookie.例如:

proxy_ignore_headers Set-Cookie;
proxy_hide_header Set-Cookie;

您应该打开错误日志记录，然后查看它。我对 fastcgi 缓存也有类似的问题，问题是文件夹权限。
