无法设置gunicorn守护进程

我无法在 ec2 实例中设置 Gunicorn 守护进程。以下是示例代码和错误/日志消息。

myproject-backend/gunicorn.conf

import os
import multiprocessing

from dotenv import load_dotenv

# load .env file
APP_ROOT = os.path.dirname(__file__)
dotenv_path = os.path.join(APP_ROOT, '.env')
load_dotenv(dotenv_path=dotenv_path)

# Please refer http://docs.gunicorn.org/en/latest/settings.html# for ducumentation.
bind = os.getenv('GUNICORN_BIND')
workers = multiprocessing.cpu_count() * 2 + 1
daemon = True
preload = True
reload = False
umask = os.getenv('GUNICORN_UMASK')
group = os.getenv('GUNICORN_GROUP')
user  = os.getenv('GUNICORN_USER')
pythonpath = os.getenv('PYPATH')

myproject-backend/.env

# This will load environment specific dynamic configurations.
# possible value - "development", "testing", "stage", "production"
INSTANCE_TYPE="production"

# gunicorn config
GUNICORN_UMASK=0
GUNICORN_GROUP='ubuntu'
GUNICORN_USER='ubuntu'
GUNICORN_BIND='localhost:8080'
#GUNICORN_BIND='127.0.0.1:8080'
PYPATH='/home/ubuntu/project/myproject-backend/'

。 须藤journalctl -u Gunicorn

8 月 27 日 00:47:15 ip-172-31-40-176 systemd[1]：启动了 Gunicorn 守护进程。 8 月 27 日 00:58:09 ip-172-31-40-176 systemd[1]：启动了 Gunicorn 守护进程。

如果您使用注释ExecStart行，/etc/systemd/system/gunicorn.service那么一切看起来都不错，但我想gunicorn从配置文件运行。这个怎么做？

答案1

gunicorn.cfg当我更改时在文件中

umask = os.getenv('GUNICORN_UMASK')
group = os.getenv('GUNICORN_GROUP')
user  = os.getenv('GUNICORN_USER')

到

umask = 0
user = None
group = None

然后一切看起来都很好。我不知道为什么以及如何。但是的，它解决了问题。如果这里有人可以向我解释那就太好了。
