無法使用Nginx + Unicorn服務於多個Rails應用程序

Question

我知道這是一個非常普遍的問題，但是這次我一直在努力解決一個奇怪的問題：

我想在同一VPS（ubuntu 14.04）上提供兩個Rails 4應用程序。 我遵循本指南成功開發了一個應用程序。 我的app1運行正常。 但不是app2。

錯誤是此錯誤（/var/log/nginx/error.log）：

目錄索引“ / srv / app1 / public / app2 /”被禁止

常規nginx.conf

    # Run nginx as www-data.
    user www-data;
    # One worker process per CPU core is a good guideline.
    worker_processes 1;
    # The pidfile location.
    pid /var/run/nginx.pid;

    # For a single core server, 1024 is a good starting point. Use `ulimit -n` to
    # determine if your server can handle more.
    events {
        worker_connections 1024;
    }

為什么Nginx在app1的公用文件夾中尋找app2？

Answer 1

問題是您的2個Nginx服務器塊正在偵聽相同的域名。

將位置塊/ app2和unicorn_app2移到site-available / app1中

並刪除site-available / app2

此答案顯示了一個示例。
