仅用于 nginx 的静态配置？

我试图为使用 try_files 的 nginx 获取仅静态配置，但遇到了一些问题。以下是我现在正在工作的内容（但不处理目录，显示索引等）我想看看我是否可以得到一个 try_files 工作的版本......

  server {
    listen 80;
    server_name foo.com;
    rewrite ^ http://www.foo.com$uri permanent;
  }

  # the server directive is nginx's virtual host directive.
  server {
    # port to listen on. Can also be set to an IP:PORT
    listen 80;

    # Set the charset
    charset utf-8;

    # Set the max size for file uploads to 10Mb
    client_max_body_size 10M;

    # sets the domain[s] that this vhost server requests for
    server_name www.foo.com; 

    # doc root
    root /var/www/foo.com;

    # vhost specific access log
    access_log  /var/log/nginx_access.log  main;


    # Set image format types to expire in a very long time
    location ~* ^.+\.(jpg|jpeg|gif|png|ico)$ {
        access_log off;
        expires max;
    }

    # Set css and js to expire in a very long time
    location ~* ^.+\.(css|js)$ {
        access_log off;
        expires max;
    }

    location /blog {
     rewrite ^ http://blog.foo.com permanent; 
    }

    # Catchall for everything else
    location / {
      root /var/www/foo.com;
      access_log off;

      index index.html index.shtml;
      expires 1d;

      #try_files $uri $uri/;

      if (-f $request_filename) {
        break;
      }
    }

    location ~* ^/(pkg|rpms)/ {
      autoindex on;
    }

    error_page 500 502 503 504 /500.html;
    error_page 404 /404.html;

  }
