Question

我以错误的参数开始工作，这将导致它永远运行。我只是用kill -9杀死了主要的芹菜过程。之后，该服务将无法启动，而我却无法启动。从命令行运行时，它可以正常启动。我正在运行Ubuntu 18.04。日志文件已创建，但具有0个字节。

这是systemctl status celery的输出：

user@ubuntu18-0:~/repository/backend$ systemctl status celery
● celery.service - Celery Service

以下是手动启动它的输出：

./start_celery.sh
celery multi v4.3.0 (rhubarb)

        > ubuntu18-0@ubuntu18-0: OK

这是我的celery.service：

[Unit]
Description=Celery Service
After=network.target

[Service]
Type=forking
EnvironmentFile=/etc/celery.conf
WorkingDirectory=/home/user/repository/backend
ExecStart=/bin/sh -c '${CELERY_BIN} multi start ${CELERYD_NODES} -A ${CELERY_APP} --pidfile=${CELERYD_PID_FILE}  --logfile=${CELERYD_LOG_FILE} --loglevel=${CELERYD_LOG_LEVEL} ${CELERYD_OPTS}'
ExecStop=/bin/sh -c '${CELERY_BIN} multi stopwait ${CELERYD_NODES} --pidfile=${CELERYD_PID_FILE}'
ExecReload=/bin/sh -c '${CELERY_BIN} multi restart ${CELERYD_NODES} -A ${CELERY_APP} --pidfile=${CELERYD_PID_FILE} --logfile=${CELERYD_LOG_FILE} --loglevel=${CELERYD_LOG_LEVEL} ${CELERYD_OPTS}'
Restart=no
#RestartSec=60

[Install]
WantedBy=multi-user.target

这是/etc/celery.conf：

# Names of node, adapt depending on host
CELERYD_NODES="ubuntu18-0"

ENV_PYTHON="/home/user/venv/bin/python3"

# Absolute or relative path to the 'celery' command:
CELERY_BIN="/home/user/venv/bin/celery"

# App instance to use
# comment out this line if you don't use an app
CELERY_APP="asynchronous.async_tasks.celery"

# Where to chdir at start.
CELERYD_CHDIR="/home/user/repository/backend/"

# Extra command-line arguments to the worker
CELERYD_OPTS="--concurrency=4 -Ofair -Q hcs_async,celery"

# Set logging level to DEBUG
CELERYD_LOG_LEVEL="INFO"

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

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

重新启动没有帮助。我怀疑某个地方可能有文件告诉Systemd或celery服务处于某种不良状态。

我杀死了芹菜后，芹菜守护程序停止工作
