使用主管运行芹菜作为守护程序不起作用

Question

我有一个django应用程序,它有芹菜功能,所以我能够成功运行芹菜如下

celery -A tasks worker --loglevel=info

但作为一个众所周知的事实,我们需要将它作为守护进程运行,所以我在celery.conf文件/etc/supervisor/conf.d/夹中写了下面的文件

; ==================================
;  celery worker supervisor example
; ==================================

[program:celery]
; Set full path to celery program if using virtualenv
command=/root/Envs/proj/bin/celery -A app.tasks worker --loglevel=info

user=root
environment=C_FORCE_ROOT="yes"
environment=HOME="/root",USER="root"
directory=/root/apps/proj/structure
numprocs=1
stdout_logfile=/var/log/celery/worker.log
stderr_logfile=/var/log/celery/worker.log
autostart=true
autorestart=true
startsecs=10

; Need to wait for currently executing tasks to finish at shutdown.
; Increase this if you have very long running tasks.
stopwaitsecs = 600

; When resorting to send SIGKILL to the program to terminate it
; send SIGKILL to its whole process group instead,
; taking care of its children as well.
killasgroup=true

; if rabbitmq is supervised, set its priority higher
; so it starts first
priority=998

但是当我试图更新主管时supervisorctl reread,supervisorctl update我正在收到消息supervisorctl status

celery                           FATAL      Exited too quickly (process log may have details)

所以我去了worker.log文件,看到如下错误信息

Running a worker with superuser privileges when the
worker accepts messages serialized with pickle is a very bad idea!

If you really want to continue then you have to set the C_FORCE_ROOT
environment variable (but please think about this before you do).

User information: uid=0 euid=0 gid=0 egid=0

那么为什么它抱怨, C_FORCE_ROOT即使我们已将其设置为管理员conf文件中的环境变量？我在上面的conf文件中做错了什么？

您需要使用非超级用户帐户运行 celery，请从您的配置中删除以下行：

\n\n

user=root\nenvironment=C_FORCE_ROOT="yes"\nenvironment=HOME="/root",USER="root"\n

\n\n

并将这些行添加到您的配置中，我假设您django作为非超级用户和developers用户组使用：

\n\n

user=django\ngroup=developers\n

\n\n

\n

请注意，子进程将继承用于启动supervisord 的\n shell 的环境变量，但此处覆盖的变量\n 和program\xe2\x80\x99s 环境选项中的变量除外。参见监管文件。

\n

\n\n

因此请注意，当您通过supervisor配置文件更改环境变量时，更改将不会通过运行supervisorctl reread和来应用supervisorctl reload。您应该通过以下命令从一开始就运行主管：

\n\n

supervisord -c /path/to/config/file.conf\n

\n
