django+celery+redis+send_mail 来发送邮件

当直接 console 启动 django 项目和 celery 时候，既如下情况时候可以正常邮件发送：

启动 django

[root@vultrvpn vpnWeb]# python run.py Performing system checks... System check identified no issues (0 silenced). March 17, 2017 - 11:09:42 Django version 1.10.6, using settings 'vpnWeb.settings' Starting development server at http://0.0.0.0:9000/ Quit the server with CONTROL-C.

启动 celery

[root@vultrvpn vpnWeb]# celery -A vpnWeb worker -l info /usr/lib/python2.7/site-packages/celery/platforms.py:793: RuntimeWarning: You're running the worker with superuser privileges: this is absolutely not recommended!

当项目调用到 send_mail 时候可以正常进行邮件发送

发送邮件代码

from django.core.mail import send_mail import time from time import sleep @celery_app.task def sendEmal(tomail): send_mail( u'账号信息', u'发送目标邮箱', '[email protected]', [tomail], fail_silently=False, )

但当用 supervisor 进行守护进程部署 django 以及 celery 也部署了守护进程(按以下方式部署守护进程)

http://docs.celeryproject.org/en/latest/userguide/daemonizing.html#daemonizing 拷贝这个文件（ https://github.com/celery/celery/blob/3.1/extra/generic-init.d/celeryd ）内容到 /etc/init.d/celeryd

邮件就无法发送了。

守护进程时候 celery 调用发送邮件 task 的时候打印日志内容：

[2017-03-17 10:58:30,190: INFO/MainProcess] mingle: all alone [2017-03-17 10:58:30,197: INFO/MainProcess] djangoCelery1@vultrvpn ready. [2017-03-17 10:58:49,185: INFO/MainProcess] Received task: app.emailTask.sendEmal[1c9ff6d0-2962-42ce-ba35-151c73980ffb] [2017-03-17 11:06:51,331: INFO/MainProcess] Received task: app.emailTask.sendEmal[7b71fa6c-0554-44c3-a030-20f14885f001] [2017-03-17 11:07:44,339: INFO/MainProcess] Connected to redis://localhost:6379/0 [2017-03-17 11:07:44,347: INFO/MainProcess] mingle: searching for neighbors [2017-03-17 11:07:45,361: INFO/MainProcess] mingle: all alone [2017-03-17 11:07:45,367: INFO/MainProcess] djangoCelery1@vultrvpn ready. [2017-03-17 11:30:44,493: INFO/MainProcess] Connected to redis://localhost:6379/0 [2017-03-17 11:30:44,499: INFO/MainProcess] mingle: searching for neighbors [2017-03-17 11:30:45,526: INFO/MainProcess] mingle: all alone [2017-03-17 11:30:45,532: INFO/MainProcess] djangoCelery1@vultrvpn ready.

后有经过测试， django 部署守护进程， celery 用 console 启动，就可以正常发送邮件。

那么现在要怎么调整才能在 celery 使用守护进程部署的时候也能进行邮件发送的？
