概述

我一直在关注the docs以便设置我的守护进程,但是一直遇到一个日志文件权限错误让我难过.

以下是我在Digital Ocean上的ubuntu盒子上设置的配置

在/ etc /默认/ 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

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

我收到以下错误消息：

celery multi v3.1.7 (Cipater)

我看了这个错误信息并从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进程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！

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

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/ bin / mix_daemon中的bin是不是/ home // mix_daemon
