配置phabricator和nginx的问题

我使用phabricator站点的install_ubunbu脚本在ubuntu上安装了phabricator，该脚本已成功运行 . 我已经在服务器上安装了MySQL - 我在default.conf.php文件中添加了数据库凭据 . 我也从他们的网站复制了Nginx配置 . 我在端口82上添加了一个监听端口 . 但是，当我尝试访问浏览器中的url / port时，我收到以下Nginx错误消息（来自nginx日志）：

Error Message

           fastcgi_index index.php;

           #custom environment variable
           fastcgi_param PHABRICATOR_ENV   "custom/myconfig";  ##change this

           #required if PHP was built with --enable-force-cgi-redirect
           fastcgi_param REDIRECT_STATUS 200;

           #variables to make the $_SERVER populate in PHP
           fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
           fastcgi_param  QUERY_STRING     $query_string;

           fastcgi_param  REMOTE_ADDR      $remote_Addr;
   }
}

有关对此进行故障排除的任何想法，或者如果我需要遵循设置phabricator的其他步骤，将不胜感激 .
