AWS Beanstalk命令問題

Question

我一直在使用EBS，沒有任何問題。今天，我已經添加負載均衡器，並上傳了我的包具有以下配置：

files: 
    "/etc/nginx/conf.d/proxy.conf": 
    mode: "000755" 
    owner: root 
    group: root 
    content: | 
     proxy_set_header X-Real-IP $remote_addr; 
     proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 


container_commands: 
    01_reload_nginx: 
    command: "service nginx reload" 

然而，當我試圖啓動包，我得到以下錯誤：

Application deployment failed at 2016-11-23T14:07:40Z with exit status 7 and error: container_command 01_reload_nginx in .ebextensions/environment.config failed.

請告訴我繼續？

這些日誌：

很有可能你的NGINX配置文件被破壞，沒有通過測試時，NGINX重載。在服務重新載入期間，NGINX首先檢查你的配置文件，如果配置正確，一個HUP信號被髮送到NGINX進程，該進程正常關閉老工人並用新配置啓動新工人。

爲了驗證您的配置文件，您可以使用下面的命令：

/usr/bin/nginx -t -c ~/mynginx.conf

-t =不要跑，只是測試配置文件。 NGINX檢查配置的正確語法，然後嘗試打開配置中引用的文件。

-c filename =您的配置文件的位置（如果不是默認）

你應該能夠與下面的命令也來測試你的配置（取決於你是什麼操作系統）：

service nginx configtest

第一種變體是可取的，因爲它也會打印NGINX配置中的任何信息，警告和錯誤信息。

希望這會有所幫助。

這很有趣，因爲我們的彈性beanstalk部署昨天在.ebextensions上也失敗了。它的工作一個小時後...

AWS部署EB和S3的新版本大約在同一時間... https://aws.amazon.com/releasenotes/6845489088399156 https://aws.amazon.com/releasenotes/8532186109690530

不知AWS是錯呢？

我在平臺升級期間發生了完全相同的問題。我就此與AWS支持部門聯繫：他們表示，他們無法複製，但有一條非常有趣的信息實際上可以防止這種情況發生。

However, [command: "sudo service nginx reload"] is not necessary as nginx service restarts automatically after every successful deployment.

所以你可以刪除腳本的

container_commands: 
    01_reload_nginx: 
    command: "service nginx reload" 

一部分，所以你再也不用重裝失敗。
