芹菜工人在 aws 弹性豆茎中失败 [退出：芹菜工人（退出状态 1；未预期）]答案

【问题描述】：

我一直在尝试遵循有关如何将带有 celery worker 的 django 应用程序部署到 aws elastic beanstalk 的详尽说明：

How to run a celery worker with Django app scalable by AWS Elastic Beanstalk?

我在安装 pycurl 时遇到了一些问题，但通过以下评论解决了：

Pip Requirements.txt --global-option causing installation errors with other packages. "option not recognized"

然后我得到了：

[2019-01-26T06:43:04.865Z] INFO  [12249] - [Application update app-190126_134200@28/AppDeployStage0/EbExtensionPostBuild/Infra-EmbeddedPostBuild/postbuild_1_raiseflags/Command 05_celery_tasks_run] : Activity execution failed, because: /usr/bin/env: bash
  : No such file or directory
   (ElasticBeanstalk::ExternalInvocationError)

但也解决了：原来我必须将“celery_configuration.txt”文件转换为 UNIX EOL（我使用的是 Windows，Notepad++ 自动将其转换为 Windows EOL）。

通过所有这些修改，我可以成功部署项目。但问题是周期性任务没有运行。

我明白了：

我也有这部分日志：

我不知道它是否与错误有关，但请注意 [[ PATH="/opt/python/run/venv/bin/:%%(ENV_PATH)s" ]] 行上方 - -> ENV_PATH 不应该是别的吗？：

environment=PYTHONPATH="/opt/python/current/app/:",PATH="/opt/python/run/venv/bin/:%%(ENV_PATH)s",RDS_PORT="5432",RDS_DB_NAME="ebdb",RDS_USERNAME="foobar",PYCURL_SSL_LIBRARY="nss",DJANGO_SETTINGS_MODULE="raiseflags.settings",RDS_PASSWORD="foobar",RDS_HOSTNAME="something.something.eu-west-1.rds.amazonaws.com"

我是第一次使用 celery 部署应用程序，说实话我真的很迷茫。我为解决前两个错误付出了很多努力（我真的很业余），现在我得到了这个我什至不知道从哪里开始。

另外，我不确定我是否以正确的方式使用“celery_configuration.txt”。我唯一编辑的是两个地方写着“django_app”，我把它改成了“raiseflags”（我的 django 项目的名称）。这是正确的吗？

有人知道怎么解决吗？如果需要，我可以粘贴我的文件，但它们就像第一个链接中提供的一样。我正在使用 Windows。

非常感谢！

【解决方案1】：

好的，问题与我所指的 PATH 行无关。我只需要在我的设置中的 INSTALLED_APPS 中添加“django_celery_beat”和“django_celery_results”。py

我后来提到与 Fran 交谈的连接错误是因为我需要在 settings.py 文件中设置 BROKER_URL 而不是 CELERY_BROKER_URL。我想这与我没有在 celery.py 文件中的 app.autodiscover_tasks() 中将“CELERY”指定为命名空间有关（尽管在链接的问题中他们这样做了，但我没有这样做，因为我使用的是不同的芹菜的版本）。

感谢 Fran 所做的一切，特别是指出我应该查看 celery 错误日志。我不知道该怎么做。如果任何其他业余爱好者也在苦苦挣扎，请知道您必须“eb ssh”到您的实例，然后“tail -n 40 /var/log/celery-worker.log”和“”tail -n 40 /var/log/ celery-beat.log”（其中“40”是您要阅读的行数）。我知道这对很多人来说听起来很明显，但是，愚蠢的我，我不知道。

（顺便说一句，我还在为芹菜工人的问题苦苦挣扎，找不到 pycurl 模块，但这与这个问题无关）。

【解决方案2】：

参考你指出的那一行 environment=PYTHONPATH="/opt/python/current/app/:",PATH="/opt/python/run/venv/bin/:%%(ENV_PATH)s",RDS_PORT="5432",RDS_DB_NAME="ebdb",RDS_USERNAME="foobar",PYCURL_SSL_LIBRARY="nss",DJANGO_SETTINGS_MODULE="raiseflags.settings",RDS_PASSWORD="foobar",RDS_HOSTNAME="something.something.eu-west-1.rds.amazonaws.com"，您是从某处复制此行吗？因为我在您发布的链接中没有看到它。在链接的答案中是environment=$celeryenv，其中$celeryenv 被定义为

celeryenv=`cat /opt/python/current/env | tr '\n' ',' | sed 's/export //g' | sed 's/$PATH/%(ENV_PATH)s/g' | sed 's/$PYTHONPATH//g' | sed 's/$LD_LIBRARY_PATH//g' | sed 's/%/%%/g'`
celeryenv=${celeryenv%?}```

【讨论】：

抱歉，这里有误会。这一行来自错误日志，显示（我猜）这是环境。但是，是的，我将它定义为链接的答案，你展示的方式。
如果你用 ssh 连接到远程机器并给出命令cat /opt/python/current/env | tr '\n' ',' | sed 's/export //g' | sed 's/$PATH/%(ENV_PATH)s/g' | sed 's/$PYTHONPATH//g' | sed 's/$LD_LIBRARY_PATH//g' | sed 's/%/%%/g'，输出是什么？另外，也许您可以查看 celery 日志，以了解更多详细信息
如果我回显 $ENV_PATH 我什么也得不到。如果我回显 $PATH 我得到这个：prntscr.com/mcfmjl （编辑：我输入了几次命令，因为我什么也没得到，也不知道该怎么做。然后我才进入回声。澄清以防这会影响结果）
重新部署并再次连接 ssh 并输入您的命令。这就是我得到的：prntscr.com/mcfr2o
芹菜原木呢？你打开了吗？如果您尝试在没有守护进程的情况下运行 celery，它会启动吗？我使用 celery 部署了许多应用程序，但从未使用 beanstalk，所以我不知道您是否必须在配置中自定义路径或者这些是标准位置。有时直接运行 celery 可以揭示问题是守护进程还是任务本身。并且检查您拥有的所有日志（如celery 日志和supervisor 日志）是强制性的。
