    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

    启动 celery

    [root@vultrvpn vpnWeb]# celery -A vpnWeb worker -l info

    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 11:07:44,339: 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

    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?

    控制台正常, supervisor 不正常,很多时候都是编码问题引起的。
    你在 supervisor 里指定编码看看。

    [supervisord]
    environment=LANG="en_US.utf8", LC_ALL="en_US.UTF-8", LC_LANG="en_US.UTF-8"

    控制台正常, supervisor 不正常
    也有可能是工作目录或者环境变量没配。

    @vicalloy 是环境变量问题,我的发送邮箱的账号密码写入到 /etc/profile 中了
    用了你这个方式 就可以加载到账号密码变量了。
    多谢哈。
