celery守护程序 - 日志文件中的权限被拒绝

Question

我一直在努力将我的celery任务设置为守护进程,以便按计划处理数据.

我一直在关注文档以设置我的守护进程,但是一直在遇到一个日志文件权限错误,这让我很难过.

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,从redmine项目中看到了这个答案.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!

根据文档：

初始化脚本只能由root使用，shell配置文件也必须由root拥有”

所以，你需要运行：

sudo chown root:root /etc/default/celeryd

和

sudo /etc/init.d/celeryd start

顺便说一下，你的 celeryd 配置文件中有无效的语法：

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

“=”运算符中不允许有空格，正确的是：

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

另请检查您的垃圾箱是否位于 /mix_daemon 而不是 /home//mix_daemon
