django - AWS Elastic Beanstalk 上的 Celery 配置问题 - "No config updates to processes"

Question

我在 AWS Elastic Beanstalk 上部署了一个 Django 2 应用程序，我正在尝试配置 Celery 以便在同一台机器上执行异步任务。

我的文件:

02_packages.config

files:
  "/usr/local/share/pycurl-7.43.0.tar.gz" :
    mode: "000644"

    # run this before PIP installs requirements as it needs to be compiled with OpenSSL
    command: 'python3 get-pip.py'

container_commands:
  03_pycurl_reinstall:
    # run this before PIP installs requirements as it needs to be compiled with OpenSSL
    # the upgrade option is because it will run after PIP installs the requirements.txt file.
    # and it needs to be done with the virtual-env activated
    command: 'source /opt/python/run/venv/bin/activate && pip3 install /usr/local/share/pycurl-7.43.0.tar.gz --global-option="--with-nss" --upgrade'

03_django.config

    command: "source /opt/python/run/venv/bin/activate && python manage.py createsu"

  03_update_permissions: # custom django-admin command to update user perms
    command: "source /opt/python/run/venv/bin/activate && python manage.py update_permissions"
    leader_only: true
  04_collectstatic:
    command: "django-admin.py collectstatic --noinput"
  05_pip_upgrade:
    command: /opt/python/run/venv/bin/pip install --upgrade pip

更新 1

根据/var/log/celery-beat.log，celery 似乎无法找到我的项目模块。我认为我的项目结构不是 Celery 期望的那种。如何在不改变整个项目结构的情况下让它工作？

我的项目结构如下:

-- myprof-folder/
   -- requirements.txt
   -- .ebextensions/
   -- celery_conf/
      -- __init__.py
      -- config.py
   -- myproj/
      -- __init__.py
      -- settings.py # base settings
      -- settings_prod.py # production settings
      -- urls.py
      -- wsgi.py
      -- myapp1/
         -- models.py
         -- urls.py
         -- apps.py
         -- views.py
         -- tasks.py # here my app's tasks
         -- ...
      -- myapp2/
      -- myapp3/
      -- ...
      -- myappN/

更新 2

99_celery.config 使用 --workdir 选项，将 /tmp 作为目录。不需要该选项。我还对该文件进行了一些更改。

Answer 1

所以你的配置有多个问题

<强>1。 celery 类不正确

command=/opt/python/run/venv/bin/celery worker -A myproj --loglevel=INFO --logfile="/var/log/celery/%%n%%I.log" --pidfile="/var/run/celery/%%n.pid"

按照你的结构应该是

command=/opt/python/run/venv/bin/celery worker -A celery_conf.celery_app:app --loglevel=INFO --logfile="/var/log/celery/%%n%%I.log" --pidfile="/var/run/celery/%%n.pid"

<强>2。 Unicode 破折号而不是 -

你在配置中有一个 unicode en-dash 或其他东西，可能是你从某个网站复制的，而不是 - 在你的下面的命令中

command=/opt/python/run/venv/bin/celery worker -A myproj --loglevel=INFO --logfile="/var/log/celery/%%n%%I.log" --pidfile="/var/run/celery/%%n.pid"

<强>3。不附加 celerybeat.conf 和 celery.conf

下面的代码不工作

if ! grep -Fxq "[include]" /opt/python/etc/supervisord.conf
 then
    echo "[include]" | tee -a /opt/python/etc/supervisord.conf
    echo "files: celery.conf" | tee -a /opt/python/etc/supervisord.conf
fi

因为包含已经是 uswgi.conf

的一部分

<强>4。缺少 inet_server 配置

虽然你的问题有以下内容

if ! grep -Fxq "[inet_http_server]" /opt/python/etc/supervisord.conf
    then
        echo "[inet_http_server]" | tee -a /opt/python/etc/supervisord.conf
        echo "port = 127.0.0.1:9001" | tee -a /opt/python/etc/supervisord.conf
fi

但是您没有使用它，这会导致以下问题

[Instance: i-00c786a77c1f5ec11] Command failed on instance. Return code: 2 Output: (TRUNCATED)... ERROR: already shutting down error: , : file: /usr/lib64/python2.7/xmlrpclib.py line: 800 error: , : file: /usr/lib64/python2.7/xmlrpclib.py line: 800.
