【问题描述】：

我一直致力于将我的 celery 任务设置为守护进程，以便按计划处理数据。

我一直在关注the docs 以设置我的守护程序，但遇到了让我难过的日志文件权限错误。

以下是我在 Digital Ocean 上的 ubuntu 机器上设置的配置

/etc/default/celeryd

# here we have a single node
CELERYD_NODES="w1"

CELERY_BIN = "/mix_daemon/venv/bin/celery"
CELERYD_CHDIR="/mix_daemon/"

CELERYD_OPTS="-A tasks worker --loglevel=info --beat"

# %n will be replaced with the nodename.
CELERYD_LOG_FILE="/var/log/celery/%n.log"
CELERYD_PID_FILE="/var/run/celery/%n.pid"
CELERY_CREATE_RUNDIR=0
CELERY_CREATE_LOGDIR=0

# Workers should run as an unprivileged user.
CELERYD_USER="celery"
CELERYD_GROUP="celery"

但是，当我跑步时

sh -x /etc/init.d/celeryd start

我收到以下错误消息：

celery multi v3.1.7 (Cipater)
> Starting nodes...

IOError: [Errno 13] Permission denied: '/var/log/celery/celery.log'
+ sleep 5
+ exit 0

我查看了这条错误消息，并从 redmine 项目中看到了 this answer。所以我尝试了以下尝试允许芹菜工人写入日志文件：

$ sudo mkdir -p -m 2755 /var/log/celery
$ sudo chown celery:celery /var/log/celery

但是当我尝试启动守护进程时，同样的错误仍然存在。

我是一个芹菜菜鸟，任何对此的帮助将不胜感激！

【解决方案1】：

对我有帮助：

sudo chown -R myuser:root /var/run/celery/
sudo chown -R myuser:root /var/log/celery/

【解决方案2】：

根据文档：

init脚本只能由root使用，shell配置文件也必须为root拥有”

所以，你需要运行：

sudo chown root:root /etc/default/celeryd

和

sudo /etc/init.d/celeryd start

顺便说一句，你的 celeryd 配置文件中有无效的语法：

CELERY_BIN = "/mix_daemon/venv/bin/celery"

“=”运算符不允许有空格，正确的是：

CELERY_BIN="/mix_daemon/venv/bin/celery"

还要检查，您的 bin 是否位于 /mix_daemon 而不是 /home//mix_daemon
