原子部署：在Nginx重新加载之后，PHP-FPM仍然指向旧的webroot

我正在尝试使用Nginx和带有Opcache的PHP5.5-FPM进行原子部署 .

这个想法只是在nginx.conf中更改webroot，然后运行

nginx重新加载

我'm expecting is that Nginx will wait for the current requests to end and then reload itself passing the new webroot path to PHP FPM, but it'无法正常工作：PHP FPM仍然从旧目录加载PHP文件 . 我在Ngnix中使用（未记录的）$ realpath_root，以便不获取符号链接（/ prod / current），而是获取真实路径 . 这里记录了这个技术：http://codeascraft.com/2013/07/01/atomic-deploys-at-etsy/调试Nginx我可以清楚地看到它正在传递新的（真实的）路径 .

    2014/09/23 17:13:22 [debug] 26234#0: *1742 http script copy: "APPLICATION_ENV"

为了使它工作，我必须运行

php-fpm reload

但我失去了一些要求 .

'recv（）失败（104：对等连接重置）从上游读取响应头时'

这是我正在使用的nginx文件：

server {
  listen              26023;

  server_name         prod.example.com;

  client_max_body_size  20m;
  client_header_timeout 1200;
  client_body_timeout   1200;
  send_timeout          1200;
  keepalive_timeout     1200;


  access_log  /var/logs/prod/nginx/prod.access.log main;
  error_log   /var/logs/prod/nginx/prod.error.log;

  set $root_location /var/www/htdocs/prod/current/web;
  root $root_location;

  try_files   $uri $uri/ /index.php?$args;
  index       index.php;


  location ~ \.php$ {
    fastcgi_pass    unix:/var/run/php5-fpm/prod.sock;
    fastcgi_index   index.php;

    include         fastcgi_params;

    fastcgi_connect_timeout 1200;
    fastcgi_send_timeout    1200;
    fastcgi_read_timeout    1200;
    fastcgi_ignore_client_abort on;

    fastcgi_param   SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
    fastcgi_param   DOCUMENT_ROOT   $realpath_root;

    fastcgi_param   APPLICATION_ENV live;
    fastcgi_param   HTTPS           $thttps;
  }

}

这是池conf：

:~$ curl http://127.0.0.1/fpm_status_prod

有什么建议吗？
