nginx的proxy_cache如何配的？老出错

 nginx.conf
 http{
 ...
 proxy_temp_path /data/proxy_temp_path
 proxy_cache_path /data/proxy_cache_path levels=1:2 key_zone=cache_one:200m inactive=1d max_size=1g
 ## /data/proxy_temp_path/data/proxy_cache_path都存在。
 }
 default.conf 
 server {
 location / {
 ...
 proxy_cache cache_one; #使用cache_one这个keys_zone
 proxy_cache_valid 200 301 302 1d; #200,301,302状态码保存1小时
 proxy_cache_valid any 1h; #其它的保存一小时
 }
 location ~ .*\.(gif|jpg|png|txt|htm|html|css|js|flv|ico|swf)(.*) {
 expires 6h; #设置浏览器过期时间
 proxy_redirect off;
 proxy_set_header Host $host;
 proxy_cache cache_one;
 proxy_cache_valid 200 301 302 1d;
 proxy_cache_valid any 1d;
 expires 30d;
 }
 }
