无法服务于多个电源轨的应用与Nginx的+独角兽

Question

我知道这是一个很常见的问题，但我一直在这个时候挣扎天，一个奇怪的一个：

我想为两条轨道上的4个应用程序相同的VPS（Ubuntu 14.04）。我跟着this guide为一个应用程序成功。我的app1工作正常。但不是app2。

该错误是这一个（/var/log/nginx/error.log）：的 “/ SRV/APP1 /公共/ APP2 /” 被禁止

这是为什么nginx的是APP1的公用文件夹寻找APP 2？

Answer 1

问题是您的2个nginx服务器块正在侦听相同的域名。

移动位置块/ APP2和unicorn_app2进入位点可用/ APP1

和删除位点可用/ APP2

这answer显示了一个例子。
