celeryd 以服务启动的配置

1 先down脚本，将脚本放到/etc/init.d/ 目录下，名字为：celeryd
地址： https://github.com/ask/celery/blob/master/contrib/generic-init.d/celeryd

exit 0

脚本内容不用做任何更改，秩序将脚本文件变为可执行即可

2 第二个脚本，放在/etc/default/目录夏，为服务配置文件，名字为：celeryd_default
内容如下：

# 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="/Application/cooler/conf" # 为你的celeryconfig.py目录
ENV_PATH="/usr/local/bin" # 为你的python环境目录
CELERYD_MULTI="$ENV_PATH/celeryd-multi"
CELERYCTL="$ENV_PATH/celeryctl"

# Extra arguments to celeryd
CELERYD_OPTS="-l info -P eventlet -c 2 -Q celery "

# Name of the celery config module.
CELERY_CONFIG_MODULE="celeryconfig"

# %n will be replaced with the nodename.
CELERYD_LOG_FILE="/Application/cooler/logs/celery.log"
CELERYD_PID_FILE="/Application/cooler/logs/celery.pid"

# Workers should run as an unprivileged user.
CELERYD_USER="root" #系统用户名
CELERYD_GROUP="root" #系统用户群组

按照自己要求改

大功告成，自己试试吧～～～
