使用 sudo 命令启动 celery

Question

我正在使用 Celery 并尝试使用 sudo 启动它。 sudo celery multi start worker --app=app.celery --loglevel=info --concurrency=1 我需要运行使用 sudo 命令，但是当我这样做时，我遇到了权限错误。如何使用 sudo 命令启动 Celery？

我已尝试阅读文档，但不清楚 Celery Docs

sudo celery multi start worker --app=app.celery --loglevel=info --concurrency=1
celery multi v4.2.1 (windowlicker)
> Starting nodes...
    > worker@xr-npu-perf-lnx: OK

Answer 1

由于日志目录的位置，您运行遇到权限错误。您可以使用 -f 指定日志文件。所以也许是这样的：

sudo celery multi start worker --app=app.celery --loglevel=info --concurrency=1 -f /tmp/celery.log

应该可以解决问题。如果没记错的话，您可能还必须将 C_FORCE_ROOT 环境变量设置为 1 才能使其正常工作。
