celery守护程序-拒绝日志文件权限

Question

我一直在将celery任务设置为守护程序，以便按计划处理数据。

我一直在关注文档以设置我的守护程序，但是一直遇到一个日志文件权限错误，这让我感到困惑。

以下是我在Digital Ocean的ubuntu盒上设置的配置

/ 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)

我查找了此错误消息，并从redmine项目中看到了这个答案 。 因此，我尝试了以下尝试以允许芹菜工作者写入日志文件：

$ 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程序时仍然存在相同的错误。

我是一个芹菜菜鸟，对此的任何帮助将不胜感激！

Answer 1

它帮助到我：

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

Answer 2

根据文档：

初始化脚本只能由root使用，并且shell配置文件也必须归root所有”

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，您的celeryd配置文件中的语法无效：

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

“ =”运算符不允许使用空格，正确的是：

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

还要检查一下，是否在/ mix_daemon中有bin，而不是/ home // mix_daemon
