Gunicorn状态为活动(退出)，但显示未在监视器中运行

Question

我正在尝试从头开始在服务器上设置一个新的django项目(django+gunicorn+nginx)，除了gunicorn的初始化脚本外，我的一切都是正确的。

如果我手动运行gunicorn命令，它可以工作，我可以在ip地址上查看我的网站，但是当我尝试做service gunicorn start时，它给我这个输出，它不工作…

gunicorn-project.service

Nov 17 04:23:56 project systemd[1]: Started gunicorn-project.service.
Nov 17 04:25:01 project systemd[1]: Started gunicorn-project.service.

我不明白为什么会发生这种情况…

"""gunicorn WSGI server configuration."""
from multiprocessing import cpu_count
from os import environ

def max_workers():
    return cpu_count() * 2 + 1
max_requests = 1000
worker_class = 'gevent'
workers = max_workers()
errorlog = '/home/gunicorn-project/log/gunicorn/error.log'
accesslog = '/home/gunicorn-project/log/gunicorn/access.log'

我刚刚遇到了同样的错误信息(你是否也遵循了Digital Ocean教程?)，并花了几个小时试图弄清楚它。我不知道你是否还需要它，但也许我可以让别人不像我那样浪费那么多时间。

我设法修复它(经过几次不同的尝试):

1. 停止gunicorn:

   sudo systemctl stop gunicorn

2. 修改包含gunicorn.service的两个目录的写权限:

   sudo chmod u+x /etc/systemd/system/multi-user.target.wants/gunicorn-project.service

   sudo chmod u+x /etc/systemd/system/gunicorn-project.service

3. 手动删除和重建gunicorn-project.service符号link:

   unlink /etc/systemd/system/multi-user.target.wants/gunicorn-project.service

   rm /etc/systemd/system/multi-user.target.wants/gunicorn-project.service

   ln -s /etc/systemd/system/gunicorn-project.service /etc/systemd/system/multi-user.target.wants/gunicorn-project.service

4. 重新加载gunicorn守护进程:

   sudo systemctl daemon-reload

5. 重启gunicorn:

   sudo systemctl start gunicorn

   sudo systemctl enable gunicorn

状态变为active (running)。基本上，在某些时候，我没有设置适当的权限就安装了gunicorn。一旦我用正确的权限重新执行了这些步骤，gunicorn就能够按预期执行了。

OBS:我的文件被命名为gunicorn.service，我相信这是默认的。我改成了gunicorn-project.service来匹配OP的术语。
