尝试启动一项服务以将 gunicorn 作为 Flask 的后端服务器运行,但无法正常工作。运行 nginx 作为 React 的前端服务器,工作正常。
服务器:
Virtualization: vmware
Operating System: Red Hat Enterprise Linux 8.4 (Ootpa)
CPE OS Name: cpe:/o:redhat:enterprise_linux:8.4:GA
Kernel: Linux 4.18.0-305.3.1.el8_4.x86_64
Architecture: x86-64
/etc/systemd/system/myservice.service中的服务文件:
[Unit]
Description="Description"
After=network.target
[Service]
User=root
Group=root
WorkingDirectory=/home/project/app/api
ExecStart=/home/project/app/api/venv/bin/gunicorn -b 127.0.0.1:5000 api:app
Restart=always
[Install]
WantedBy=multi-user.target
/应用程序/api:
-rwxr-xr-x. 1 root root 2018 Jun 9 20:06 api.py
drwxrwxr-x+ 5 root root 100 Jun 7 10:11 venv
错误信息:

试过了,不行:
- [Service]下添加Environment="PATH=/home/project/app/api/venv/bin"
- $ systemctl reset-failed myservice.service
- $ systemctl 守护进程重载
- 重启,ofc。
试过,工作:
- 在/app/api目录中运行(以 root 身份)/home/project/app/api/venv/bin/gunicorn -b 127.0.0.1:5000 api:app
有谁知道如何解决这个问题?
