我是Nginx的新手，并且正在尝试使用nginx和thin。
我尝试了很多网站和博客，但它没有帮助。我正在关注博客 http://articles.slicehost.com/2008/5/27/ubuntu-hardy-nginx-rails-and-thin
但是我收到了502 Bad gateway错误。
以下是我实施的代码。

在发出services nginx start命令后，我无法运行瘦服务器。当我点击我的IP地址192.168.1.238时，我收到502错误的网关错误。

上述解决方案并没有帮助我。有人可以帮助我。 我现在已经停留了很长时间。

这意味着您的瘦服务器未运行。试试这个：
curl -v http://localhost:3000
可能不起作用。查看Thin日志（stdout / stderr.log）以确定进一步的问题。
Thin是一个单独的进程，应该单独重新启动。通常在同一捆绑包中的Rails应用程序中进行设置。在这种情况下，您需要运行它：
bundle exec thin start
请参阅：http://code.macournoyer.com/thin/usage/
如果您以root身份安装了Gems，包括thin gem，那么它应该在/etc/init.d中安装了一个init脚本。在这种情况下，您可以使用service命令重新启动瘦。
部署新代码时，只需重新启动瘦服务器而不是nginx。
