在本地测试，上传成功，然后运行到服务器 (阿里云) 后，图片不能上传。
排查原因： 1.ImageMagick 问题，已经安装，，，，
运行 convert -version 显示：Version: ImageMagick 6.6.9-7 2014-03-06 Q16 http://www.imagemagick.org Copyright: Copyright (C) 1999-2011 ImageMagick Studio LLC Features: OpenMP
2.服务器前端用 nginx 代理，超时是默认的 60s，大小是 10M， 3.本地测试的时候能够成功，
请问，请高人指点，给解题思路！
已经成功上传，非常感谢 Qing Wang

#13 楼 @blacktulip 时间戳错误意味着没有使用 nginx 代理，我知道了，以前我用的是这个东西的代理，换了项目，一直部署不上，我就用直接 rails s -e production 了，所以错误没有记录！这个东西是没法排查了，production.log 也没有记录，那就只有 rack server 了！！请问 rack server 的 log 信息在哪，
