nginx的：網站中502網關錯誤重定向

我是新來的Nginx，並嘗試使用nginx的和薄。nginx的：網站中502網關錯誤重定向

我已經嘗試了很多網站和博客，但它不是helping.I我目前跟蹤的博客 http://articles.slicehost.com/2008/5/27/ubuntu-hardy-nginx-rails-and-thin

但是我得到一個502錯誤網關錯誤。

把services nginx start命令後，我無法運行薄server.I我得到502錯誤門當我打我的IP地址192.168.1.238方式錯誤。

你在你的日誌中得到什麼錯誤？ – Danack

@Danack在連接到上游時請檢查更新後的問題 –

連接被拒絕）...「http://127.0.0.1:3002/」它幾乎像NGINX無法連接到上游以提供請求。 – Danack

這意味着您的瘦服務器沒有運行。試試這個：

 
curl -v http://localhost:3000

它可能不工作。查看您的瘦日誌（stdout/stderr.log）以確定更多問題。

薄是一個獨立的進程，並且應當單獨地重新啓動。在同一捆綁包中將它安裝在Rails應用程序中是很常見的。在這種情況下，你需要像運行：

 
bundle exec thin start

參見：http://code.macournoyer.com/thin/usage/

如果您安裝寶石爲根，包括薄的寶石，那麼它應該已經安裝在/ etc /初始化一個init腳本。 d。在這種情況下，您可以使用service命令重新啓動瘦客戶端。

在部署新的代碼，你只需要重新啓動你的瘦服務器，而不是nginx的。

如果我啓動nginx，是否意味着我的瘦服務器正在自動啓動。或者我必須使用命令「啓動瘦」來明確啓動瘦服務器？ –

編輯我的答案。 – Arya
