Question

我正在运行Nginx / unicorn我从nginx获取错误“失败（111：连接被拒绝），同时连接到上游”。它工作了一段时间，但在数字海洋支持重新启动我的液滴（另一个问题）后，我再也无法恢复工作了。我看过记忆，旋转日志，弹回服务器，nginx和独角兽。我已经尝试过更改插座的位置，名称和权限，毕竟我甚至尝试过扔圣水并在我的终端尖叫以消除恶魔。 :-)似乎我已经尝试了所有DO支持，谷歌和stackoverflow必须提供。我不知道我是否忽略了某些东西，或者我已经尝试了很多，以至于我现在搞砸了什么。这是所有的配置，分析等等......

提前感谢您对此问题的任何帮助。

Answer 1

谢谢大家。事实证明这是一个rails /权限问题。除了独角兽访问日志以及我发现问题的地方之外，我几乎无处不在。我认为最终当服务器被退回时我重新启动了rails / unicorn进程并在root用户下预编译了rails资产，这在/ tmp / cache / ....引起了一些文件夹权限问题。我设置了那些权限，chowed和viola所说的一切再次工作！ -

无法再让nginx / unicorn工作。连接到上游时nginx - connect（）失败（111：连接被拒绝）
