centos – 当NGINX启用静态缓存内容时,网站不加载静态文件

location ~* \.(ico|css|js|gif|jpg|jpeg|png)${
        expires 30d;
        add_header vary Accept-Encoding;
        access_log off;
   }

这是我的整个服务器{}：

server {
    listen        80;
    server_name  mywebsite.com www.mywebsite.com;

   #location ~* \.(ico|css|js|gif|jpg|jpeg|png)${
   #     expires 30d;
   #     add_header vary Accept-Encoding;
   #     access_log off;
   #}

    location / {
        if ($http_host ~* "^www.(.*)$"){
            set $rule_0 1$rule_0;
            set $bref_1 $1;
        }
        if ($rule_0 = "1"){
           rewrite ^/(.*)$http://$bref_1/$1 permanent;
        }
        rewrite ^/search/(.*)/(.*)/?$/index.PHP?search=$1&page=$2&type=mp3 las$
        rewrite ^/(.*)/(.*)/(.*)?$/index.PHP?search=$1&page=$2&type=$3 last;
        root   /var/www/mywebsite.com/public_html;
        index  index.PHP index.html index.htm;
    }

    location ~ \.PHP${
        fastcgi_read_timeout 300;
        root           /var/www/mywebsite.com/public_html;
        fastcgi_pass unix:/tmp/PHP5-fpm.sock;
        fastcgi_index  index.PHP;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }
}

有谁知道为什么？

更新(解决方案)：

正如Michael Hampton回答我的那样,服务器{}没有声明根,所以我按照说明将其添加到文件中.工作得很好！
