我不确定是什么引起了错误，但是这条特殊的线引起了我的注意celeryd: ERROR (no such process)。在本地，我的设置像一个咒语一样工作，我完成了所有任务，在运行工人/节拍时没有零问题，但是在生产中，主管似乎很难访问celery工人，或者celery工人无法正常启动。

我已经调试了很多，但是在找出问题所在时遇到了问题。我已经删除了变量和网址，它们似乎都还不错。如果我手动将ssh插入实例，则可以顺利运行celery
beat和celery worker，但是主管遇到了问题。

这条路径也正确吗？

; Set full path to celery program if using virtualenv
command=/opt/python/run/venv/bin/celery worker -A wellfie --loglevel=INFO

我是AWS新手，因此，如果此解决方案显而易见，我深表歉意。

Answer 1

是的，路径没问题：

command=/opt/python/run/venv/bin/celery worker -A wellfie --loglevel=INFO

我注意到您已将PYTHONPATH变量设置了两次，就像您将用eb环境属性覆盖一样？一旦将其设置在应用程序上，然后再设置在应用程序wellfie软件包上。

您的日志条目：

environment=
PYTHONPATH="/opt/python/current/app/:",
PATH="/opt/python/run/venv/bin/:%ENV_PATH)s",
RDS_PORT="5432",
PYTHONPATH="/opt/python/current/app/wellfie:",
REDIS_URL="bbbbb.bbbbb.0001.usw2.cache.amazonaws.com:6379",
RDS_DB_NAME="bbbdb",
DJANGO_SETTINGS_MODULE="wellfie.settings",
RDS_USERNAME="aaaa",
RDS_PASSWORD="bbbb",
RDS_HOSTNAME="bbbbb.bbbbb.us-west-2.rds.amazonaws.com"

我的：

environment=
PYTHONPATH="/opt/python/current/app/:",
PATH="/opt/python/run/venv/bin/:%(ENV_PATH)s",
WEBSERVER="APACHE",
CNAME="xxxxx-prod-env",
PYCURL_SSL_LIBRARY="nss",
APP_ENV="prod"

因此，我将从调查开始。要记住的另一件事是，如果您使用某些AWS服务（例如Redis），则需要使用该服务的安全组设置对其进行开放式连接，否则将无法连接。

注意事项：

1. 如果您在实例上播放，请记住有关virtualenv的信息。因此，您可以运行以下命令：

cd / opt / python / current / app &&来源/ opt / python / run / venv / bin /
activate && python manage.py

1. “ ImportError：没有名为’wellfie’的模块”可能会发生一次，并由于系统正在启动并且进程可能尚未就绪而被登录到celery-beat.log，celery-worker.log中。

2. ImportError（’没有名为xxxx.toi3pr.0001.usw2.cache.amazonaws.com的模块’）看起来像python初始化问题。

修改文件 root_folder / django_app / init.py ：

from __future__ import absolute_import, unicode_literals

# This will make sure the app is always imported when
# Django starts so that shared_task will use this app.
from django_app.celery import app as celery_app

__all__ = ['celery_app']

解决方法是更改​​：

supervisorctl -c /opt/python/etc/supervisord.conf restart celeryd

进入

supervisorctl -c /opt/python/etc/supervisord.conf restart celeryd-worker
supervisorctl -c /opt/python/etc/supervisord.conf restart celeryd-beat
