celery守护程序-拒绝日志文件权限 [英] celery daemon - permission denied on log file

问题描述

我一直在将celery任务设置为守护程序，以便按计划处理数据。

I have been working on setting up my celery task as a daemon in order to process data on a schedule.

我一直在关注文档以便设置我的守护程序，但已遇到日志文件权限错误，

I have been following the docs in order to set up my daemon, but have been running into a log file permission error that has me stumped.

下面是我在Digital Ocean上的ubuntu盒上设置的配置

Below is the configuration i have set up on an ubuntu box on Digital Ocean

/ etc / default / celeryd

/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，何时我运行

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

我收到以下错误消息：

celery multi v3.1.7 (Cipater)

我查看了此错误消息，在redmine项目中看到了此答案。因此，我尝试了以下操作，以允许芹菜工作者写入日志文件：

I looked this error message up and saw this answer from a redmine project. So i tried the following to try to allow for the celery worker to write to the log file:

$ 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程序时，仍然存在相同的错误。

but the same error remains when i try to start the daemon.

我是芹菜菜角，在这方面的任何帮助将不胜感激！

I am a celery noob, and any help on this would be greatly appreciated!

推荐答案

根据文档：

init脚本只能由root用户使用，并且shell配置文件也必须由root用户拥有。

The init scripts can only be used by root, and the shell configuration file must also be owned by root"

因此，您需要运行：

sudo chown root:root /etc/default/celeryd

和

sudo /etc/init.d/celeryd start

顺便说一下，celeryd配置文件中的语法无效：

By the way, you have invalid syntax in your celeryd config file:

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

不允许使用 =运算符使用空格，

spaces is not allowed with "=" operator, the correct is:

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

还要检查一下，您的垃圾箱位于/ mix_daemon不是/ home // mix_daemon

Also check, that you have your bin in /mix_daemon not /home//mix_daemon
