我正在尝试在一个virtualenv里面运行django的celery进程守护进程 . 我将celeryd文件从https://github.com/celery/celery/tree/master/extra/generic-init.d复制到/etc/init.d/
然后我创建了一个包含http://ask.github.io/celery/cookbook/daemonizing.html#example-django-configuration-using-virtualenv内容的配置文件，并将其保存为/ etc / default / celeryd
这是我的/ etc / default / celeryd：
# 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/manu/location/to/project/"
# Python interpreter from environment.
ENV_PYTHON="/home/manu/.virtualenvs/project_env/bin/python"
# How to call "manage.py celeryd_multi"
CELERYD_MULTI= "$ENV_PYTHON $CELERYD_CHDIR/manage.py celeryd_multi"
# How to call "manage.py celeryctl"
CELERYCTL="$ENV_PYTHON $CELERYD_CHDIR/manage.py celeryctl"
# Extra arguments to celeryd
CELERYD_OPTS="--verbose --fake --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="project.settings.production"
当我跑：
sudo sh -x /etc/init.d/celeryd start
它失败并出现以下错误：
celeryd-multi start w1 --uid = celery --gid = celery --workdir = / home / manu / location / to / project / --pidfile = / var / run / celery /％n.pid --logfile = /var/log/celery/%n.log --loglevel = INFO --cmd = -m celery.bin.celeryd_detach --verbose --fake --time-limit = 300 --concurrency = 8 / etc / init . d / celeryd：140：/etc/init.d/celeryd：celeryd-multi：未找到
我可以看到它无法找到celeryd_multi . 奇怪的是，跑步
/ path / to / project_env / bin / python /path/to/manage.py celeryd_multi
显示celeryd-multi可用 .
[Update - Correcting my start command with @Daniel Roseman's input]
现在，当我跑：
sh -x /etc/init.d/celeryd start
这是我看到的输出：
/path/to/.virtualenvs/virtenv/bin/python /path/to/project//manage.py celeryd_detach --time-limit = 300 --concurrency = 8 --gid = celery --broker = amqp：/ /：@ localhost：5672 // -n w1.ubuntu-12-10 --logfile = / var / log / celery / w1.log --loglevel = INFO --uid = celery --pidfile = / var / run / celery / w1.pid --workdir = / path / to / project / OK sleep 5 exit 0
我在这里错过了什么？请帮忙！

你的init.d脚本引用了系统python包，而不是virtualenv python . 因此，当您在其中运行芹菜时，您将引用系统站点包中安装的芹菜 .
在调用celery之前添加对virtualenv python路径的引用，一切都应该正常工作 .
话虽这么说，通常最好使用init.d运行supervisord然后让supervisord启动所有其他进程，如芹菜和您的Web应用程序 .
当您使用
sudo sh执行命令时，您的're starting a completely new shell environment. Inside that environment, your virtualenv is not activated, and the virtualenv' sbin目录将不在路径上，这可能是找不到可执行文件的原因 .如果你真的需要以超级用户身份运行它，你应该创建一个包装器脚本来执行
sudo调用中的virtualenv .
