将花添加到芹菜守护程序中

Question

是否可以向芹菜守护程序添加花？

下面是我的芹菜配置文件，我尝试在芹菜_opts变量中添加了花config，但失败了。

或我可以将另一个命令添加到配置文件中以用芹菜启动并运行花？

# 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:
CELERY_BIN="/usr/local/bin/celery"
# App instance to use
# comment out this line if you don't use an app
CELERY_APP="itapp"
# or fully qualified:
#CELERY_APP="proj.tasks:app"
# Where to chdir at start.
CELERYD_CHDIR="/itapp/itapp/"
# Extra command-line arguments to the worker
CELERYD_OPTS="flower --ports 5555 --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).
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

我建议使用supervisord或其他过程控制系统运行它们，而不是OS INIT脚本和Start-Stop-Daemon。

工人和花朵都应该作为守护程序过程并排运行，有很多关于如何使用Substisord运行芹菜工人的文档，Run Flower只是为了添加另一个程序部分，用相应的花启动命令替换工人命令，例如celery flower -A itapp --ports 5555 --time-limit=300 --concurrency=8。
