如何在ubuntu服务器上守护django芹菜定期任务？ [英] How to daemonize django celery periodic task on ubuntu server?

问题描述

在本地主机上，我使用这些语句执行任务和工作。
运行任务：
python manage.py celery beat
运行worker：
python manage.py celery worker --loglevel = info
我使用otp，rabbitmq服务器和Django的芹菜。
它工作正常。
我在ubuntu服务器上上传了该项目。我想守护这些。
为此，我创建了一个文件/ etc / default / celeryd，如下配置设置。

 ＃节点名称开始，这里我们有一个节点
 CELERYD_NODES =w1
＃或者我们可以有三个节点：$ b​​ $ b＃CELERYD_NODES =w1 w2 w3
＃在哪里chdir开始。 
 CELERYD_CHDIR =/ home / sandbox / myprojrepo / myproj
 
＃如何调用manage.py celeryd_multi
 CELERYD_MULTI =$ CELERYD_CHDIR / manage.py celeryd_multi
 
＃如何调用manage.py celeryctl
 CELERYCTL =$ CELERYD_CHDIR / manage.py celeryctl
 
＃对celeryd 
的额外参数CELERYD_OPTS = -  time-limit = 300 --concurrency = 8
  

芹菜配置模块的名称

  CELERY_CONFIG_MODULE =celeryconfig
 
＃％n将被替换为nodename。 
 CELERYD_LOG_FILE =/ var / log / celery /％n.log
 CELERYD_PID_FILE =/ var / run / celery /％n.pid
 
＃作为无特权用户。 
 CELERYD_USER =芹菜
 CELERYD_GROUP =芹菜
 
＃项目设置模块的名称。 
 export DJANGO_SETTINGS_MODULE =settings
  

另外我创建了一个文件/etc/init.d / celeryd与我下载的脚本。

现在，当我尝试执行/etc/init.d/celeryd启动它给出错误作为Unrecogonized命令行参数。
我发出celeryd-multi start nodeN作为一个命令，它表示nodeN启动。但是任务执行尚未开始。

我是新进的守护进程和服务器托管。

解决方案

您可以在主管中运行芹菜：
https：//pypi.python。 org / pypi / supervisor

hth。

On localhost, i used these statements to execute tasks and workers. Run tasks: python manage.py celery beat Run workers: python manage.py celery worker --loglevel=info I used otp, rabbitmq server and django-celery. It is working fine. I uploaded the project on ubuntu server. I would like to daemonize these. For that i created a file /etc/default/celeryd as below config settings.

# Name of nodes to start, here we have a single node
CELERYD_NODES="w1"
# or we could have three nodes:
#CELERYD_NODES="w1 w2 w3"
# Where to chdir at start.
CELERYD_CHDIR="/home/sandbox/myprojrepo/myproj"

# How to call "manage.py celeryd_multi"
CELERYD_MULTI="$CELERYD_CHDIR/manage.py celeryd_multi"

# How to call "manage.py celeryctl"
CELERYCTL="$CELERYD_CHDIR/manage.py celeryctl"

# Extra arguments to celeryd
CELERYD_OPTS="--time-limit=300 --concurrency=8"

Name of the celery config module.

CELERY_CONFIG_MODULE="celeryconfig"

# %n will be replaced with the nodename.
CELERYD_LOG_FILE="/var/log/celery/%n.log"
CELERYD_PID_FILE="/var/run/celery/%n.pid"

# Workers should run as an unprivileged user.
CELERYD_USER="celery"
CELERYD_GROUP="celery"

# Name of the projects settings module.
export DJANGO_SETTINGS_MODULE="settings"

Also i created a file /etc/init.d/celeryd with script i downloaded.

Now when i try to execute /etc/init.d/celeryd start it gives error as Unrecogonized command line argument. I issued "celeryd-multi start nodeN" as a command and it said nodeN started. But tasks execution havent started yet.

I am new to daemonizing and server hosting.

解决方案

You can run celery within supervisor: https://pypi.python.org/pypi/supervisor http://thomassileo.com/blog/2012/08/20/how-to-keep-celery-running-with-supervisor/
