Nginx，Unicorn，net :: ERR_TOO_MANY_REDIRECTS

时间：2016-05-14 05:00:18

标签： ruby-on-rails nginx rvm unicorn

当我尝试在Digital Ocean Server上访问我的rails应用程序时，我在浏览器中收到以下错误：重定向了你太多次了。在控制台：net :: ERR_TOO_MANY_REDIRECTS

此时capistrano成功部署，没有任何错误。该应用程序在本地运行完美（没有错误）。

下面是其他相关文件，从nginx，unicorn和rails的错误日志文件开始，下面还显示了nginx和unicorn的配置文件。

非常感谢任何帮助。

答案 0 :(得分：1)

好的，经过大量的挖掘后，我发现错误信息试图暗示我正在强迫HTTPS并进入某种重定向循环。我只需要在config / environments / production.rb中注释掉一行

# Force all access to the app over SSL, use Strict-Transport-Security, and use secure cookies.
# config.force_ssl = true

默认情况下这是注释掉的，我必须取消注释。必须记住以前工作中断的东西检查你的git diff以查看你所做的所有更改。看起来rails app和nginx都试图强制ssl这创建了一个不确定的重定向循环。这些其他帖子也很有帮助：

Why am I getting infinite redirect loop with force_ssl in my Rails app?

Nginx configuration leads to endless redirect loop
