按照发现here的说明，我将the script from github复制到 /etc/init.d/celeryd ，然后将其设为可执行文件;
$ ll /etc/init.d/celeryd
-rwxr-xr-x 1 root root 9481 Feb 19 11:27 /etc/init.d/celeryd*
我按照说明创建了配置文件 / etc / default / celeryd ：
# Names of nodes to start
# most will only start one node:
#CELERYD_NODES="worker1"
# but you can also start multiple and configure settings
# for each in CELERYD_OPTS (see `celery multi --help` for examples).
CELERYD_NODES="worker1 worker2 worker3"
# Absolute or relative path to the 'celery' command:
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
#CELERY_APP="proj"
# or fully qualified:
#CELERY_APP="proj.tasks:app"
# Where to chdir at start.
CELERYD_CHDIR="/path/to/folder/containing/tasks/"
# Extra command-line arguments to the worker
CELERYD_OPTS="--time-limit=3000 --concurrency=3 --config=celeryconfig"
# %N will be replaced with the first part of 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.
# You need to create this user manually (or you can choose
# a user/group combination that already exists, e.g. nobody).
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
注意：我在CELERYD_OPTS中添加了 - config = celeryconfig 部分。
我使用
创建了一个新用户芹菜sudo useradd -N -M --system -s /bin/false celery
然后创建了组芹菜并添加了用户：
$ id celery
uid=999(celery) gid=1005(celery) groups=1005(celery)
我用芹菜芹菜：文具夹芹菜：
的/ var /运行/芹菜/
的/ var /日志/芹菜/
当我尝试启动服务时，我没有发现错误迹象：
$ sudo service celeryd start
celery init v10.0.
Using config script: /etc/default/celeryd
但状态告诉我“没有找到pids”：
$ sudo service celeryd status
celery init v10.0.
Using config script: /etc/default/celeryd
celeryd is stopped: no pids were found
实际上，ps -ef没有结果，也没有创建PID文件或日志文件：
$ ll /var/run/celery
total 0
drwxr-sr-x 2 celery celery 40 Feb 19 14:13 ./
drwxr-xr-x 16 root root 620 Feb 19 12:35 ../
$ ll /var/log/celery
total 8
drwxr-sr-x 2 celery celery 4096 Feb 19 14:13 ./
drwxr-xr-x 13 root root 4096 Feb 19 11:37 ../
其他信息：
$ pip freeze | grep celery
celery==3.1.9
我错过了什么？我应该在哪里寻找更多线索，了解为什么芹菜没有开始？
答案 0 :(得分：16)
我复制了你的步骤，导致了同样的问题。问题是芹菜用户没有外壳。
sudo useradd -N -M --system -s /bin/false celery
将-s /bin/false更改为-s /bin/bash解决了问题。原因是celeryd init脚本使用celery用户的shell来执行celery命令。没有shell，下面的su命令会以静默方式退出。
_chuid () {
su "$CELERYD_USER" -c "$CELERYD_MULTI $*"
}

我使用了一个稍微不同的init脚本版本，在这里提供：
#!/bin/sh -e
# ============================================
# celeryd - Starts the Celery worker daemon.
# ============================================
#
# :Usage: /etc/init.d/celeryd {start|stop|force-reload|restart|try-restart|status}
# :Configuration file: /etc/default/celeryd
#
# See http://docs.celeryproject.org/en/latest/tutorials/daemonizing.html#generic-init-scripts
### BEGIN INIT INFO
# Provides: celeryd
# Required-Start: $network $local_fs $remote_fs
# Required-Stop: $network $local_fs $remote_fs
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: celery task worker daemon
### END INIT INFO
#
#
# To implement separate init scripts, do NOT copy this script. Instead,
# symlink it. I.e., if my new application, "little-worker" needs an init, I
# should just use:
#
# ln -s /etc/init.d/celeryd /etc/init.d/little-worker
#
# You can then configure this by manipulating /etc/default/little-worker.
#
# If you want to have separate LSB headers in each script you can source this
# script instead of symlinking:
# # ...
# ### END INIT INFO
# source /etc/init.d/celeryd
#
# Setting `SCRIPT_NAME` here allows you to symlink/source this init script,
# making it easy to run multiple processes on the system.

使用dryrun选项运行它给了我init正在构建的确切命令。
删除以下两个选项后运行该命令：
--detach
--logfile
允许我在控制台中运行它并观察python错误跟踪。
最后我必须通过redis重新安装pip模块（我用作后端）
我会将两个初始化脚本区分开来，最后混合使用它们。

我遇到过同样的问题。即使我曾尝试与root用户一起运行，我也无法启动任何工作人员。然后我遇到了这个答案https://groups.google.com/forum/#!topic/celery-users/s8OFSdWdHo8它基本上说将运行工作者的用户应该有一个主目录。
使用主目录创建另一个用户后，我能够启动工作人员。
