是否可以向芹菜守护进程添加花？

下面是我的芹菜配置文件，我尝试将花配置添加到 CELERYD_OPTS 变量中，但失败了。

或者我可以在配置文件中添加另一个命令来让花与芹菜一起运行吗？

# 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或其他进程控制系统运行它们，而不是操作系统 init 脚本和 start-stop-daemon。

worker 和flower 都应该作为守护进程并行运行，有很多关于如何使用 supervisord 运行 celery worker 的文档，runflower只是添加另一个程序部分，将 worker 命令替换为相应的 Flower 启动命令，如celery flower -A itapp --ports 5555 --time-limit=300 --concurrency=8.
