Question

根据主题
https://www.digitalocean.com/community/tutorials/how-to-serve-flask-applications-with-gunicorn-and-nginx-on-ubuntu-18-04
我设法使用

手动启动了app.py

gunicorn --bind 0.0.0.0:5000 wsgi:app

但是当我尝试提供服务以自动运行Gunicorn时，我做不到。

我创建了/etc/systemd/system/telegram_bot.service：

[Unit]
Description=Gunicorn instance to serve telegram_bot
After=network.target

[Service]
User=victor
Group=www-data
WorkingDirectory=/home/victor/bot/bot/telegram_bot
Environment="PATH=/home/victor/bot/bot/env/bin"
ExecStart=/home/victor/bot/bot/env/bin/gunicorn --workers 3 --bind unix:app.sock -m 007 wsgi:app

[Install]
WantedBy=multi-user.target

态度：
-rw-r--r--。 1胜利者www-data 352 3月26日15:17 telegram_bot.service

项目结构：
/ home / victor /
----------------- bot /
--------------------- bot /
------------------------- env /
------------------------- telegram_bot /
-------------------------------------------app.py
-------------------------------------------wsgi.py

像该主题中的app.py和wsgi.py。
-rwxr-xr-x。 1 victor victor 162 Mar 25 14:26 app.py
-rwxr-xr-x。 1 victor victor 58 Mar 24 22:08 wsgi.py

命令后

sudo systemctl start telegram_bot

我收到消息：

我浏览了journalctl并发现：

我一直在寻找解决方案两天。我错过了什么？
CentOS 7

我无法启动Gunicorn即服务
