为root用户启动celery创建的脚本,该脚本的拥有者与使用者都必须是root .
使用方法为 /etc/init.d/celeryd [start]|[stop]|[kill]

需增加两个文件 /etc/default/celeryd(配置脚本) 和 /etc/init.d/celeryd (启动脚本)

1.编辑 /etc/default/celeryd :

# Names of nodes to start
#   most people will only start one node:
CELERYD_NODES="worker1"
#   but you can also start multiple and configure settings
#   for each in CELERYD_OPTS
#CELERYD_NODES="worker1 worker2 worker3"
#   alternatively, you can specify the number of nodes to start:
#CELERYD_NODES=10

# Absolute or relative path to the 'celery' command:如果是虚拟环境中的celery则应写作 /opt/virtualenv/bin/celery
CELERY_BIN="/usr/local/bin/celery"
#CELERY_BIN="/virtualenvs/def/bin/celery"

# App instance to use
# comment out this line if you don't use an app ,在diango中实例化celery app时的name
CELERY_APP="proj"
# or fully qualified:
#CELERY_APP="proj.tasks:app"

# Where to chdir at start.对于django项目来说,用于创建celery app的文件celery.py的目录为 /opt/Myproject/Myproject/celery.py ,该目录用于查找celery app 
CELERYD_CHDIR="/opt/Myproject/"

# Extra command-line arguments to the worker
CELERYD_OPTS="--time-limit=300 --concurrency=8"
# Configure node-specific settings by appending node name to arguments:
#CELERYD_OPTS="--time-limit=300 -c 8 -c:worker2 4 -c:worker3 2 -Ofair:worker1"

# Set logging level to DEBUG
#CELERYD_LOG_LEVEL="DEBUG"

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

# Workers should run as an unprivileged user.
#   You need to create this user manually (or you can choose
#   a user/group combination that already exists (e.g., nobody).这里的用户名,用于运行celery的非root user 与 用户组
CELERYD_USER="celery"
CELERYD_GROUP="celery"

# If enabled pid and log directories will be created if missing,
# and owned by the userid/group configured.
CELERY_CREATE_DIRS=1

  




2.将下面的celeryd 文件放入目录/etc/init.d/中
#!/bin/sh -e
# ============================================
#  celeryd - Starts the Celery worker daemon.

#
# :Usage: /etc/init.d/celeryd {start|stop|force-reload|restart|try-restart|status}

# Short-Description: celery task worker daemon
### END INIT INFO
#
#
# To implement separate init scripts, copy this script and give it a different
# name:
# I.e., if my new application, "little-worker" needs an init, I
# should just use:
#
#   cp /etc/init.d/celeryd /etc/init.d/little-worker
#
# You can then configure this by manipulating /etc/default/little-worker.

对于非root 用户 可以直接执行下面语句 (celery从安全的角度是默认不允许root执行的)
$ celery multi start worker1 \
    -A proj \
