Ruby on Rails 服務器設置

Question

我正在嘗試將 ROR 應用程序部署到 Ubuntu 服務器（EC2）。 我正在使用以下版本：

• 紅寶石：2.4.0p0
• 導軌：4.2.8
• 捆綁器：1.17.3

*出於某種原因，我的同事創建了一個 gemset 而不是正常設置。

寶石環境是：

我完成了 nginx 和乘客的設置並設置了根路徑。

• nginx 版本：nginx/1.17.3
• Phusion 乘客：6.0.4

我相信 nginx 和乘客的設置沒有任何問題，但我收到以下錯誤：Phusion 乘客應用程序服務器嘗試啟動 Web 應用程序。 但是應用程序本身（而不是Passenger）遇到了內部錯誤。

錯誤詳情：

有人有任何想法嗎？

Answer 1

乘客正在嘗試下載不存在的文件。

嘗試使用 ruby​​ 2.4.6，因為該版本已在 github 發布頁面上列出

https://github.com/phusion/passenger/releases/

Answer 2

最有可能的一點是，您正在ubuntu用戶下設置和測試 rvm/ruby，但 nginx 服務器正在其他用戶下運行（該用戶沒有配置 rvm，至少在守護進程運行的會話中）

RVM 能夠創建一個包裝器，它將設置正確的路徑和 gemset（如果需要）：

rvm alias create ruby_for_my_app ruby-2.4.0@myrepo

然后在passenger_ruby nginx 配置指令中使用/home/ubuntu/.rvm/wrappers/ruby_for_my_app/ruby （記得更改后重新加載）
