Gunicorn 未開始拋出 gunicorn.service：失敗，結果為“退出代碼”。 錯誤

Question

我正在嘗試按照此鏈接在 DigitalOcean 上部署簡單的 Django 應用程序跟隨錯誤

gunicorn.service：失敗，結果為“退出代碼”。

這是我的以下配置

須藤納米 /etc/systemd/system/gunicorn.socket

[Unit]
Description=gunicorn socket

[Socket]
ListenStream=/run/gunicorn.sock

[Install]
WantedBy=sockets.target

須藤納米 /etc/systemd/system/gunicorn.service

[Unit]
Description=gunicorn daemon
Requires=gunicorn.socket
After=network.target

[Service]
User=pos
Group=www-data
WorkingDirectory=/home/pos/pos
ExecStart=/home/pos/env/bin/gunicorn \
          --access-logfile - \
          --workers 3 \
          --bind unix:/run/gunicorn.sock \
          pos.wsgi:application

[Install]
WantedBy=multi-user.target

須藤 systemctl 狀態 gunicorn.socket

● gunicorn.socket - gunicorn socket
   Loaded: loaded (/etc/systemd/system/gunicorn.socket; enabled; vendor preset: enabled)
   Active: active (listening) since Tue 2019-11-26 07:39:39 UTC; 12min ago
   Listen: /run/gunicorn.sock (Stream)
   CGroup: /system.slice/gunicorn.socket

Nov 26 07:39:39 POS systemd[1]: Listening on gunicorn socket.

當我嘗試啟動 gunicorn 時，它拋出了這個錯誤

sudo systemctl 狀態 gunicorn

● gunicorn.service - gunicorn daemon
   Loaded: loaded (/etc/systemd/system/gunicorn.service; enabled; vendor preset: enabled)

有人幫我解決這個問題嗎？

Answer 1

最新版本的gunicorn（20.0.3）會導致這個問題。

嘗試安裝舊版本的 gunicorn：

pip install gunicorn==20.0.2

Answer 2

似乎您正在嘗試在ExecStart收聽unix:/run/gunicorn.sock ExecStart ，但套接字位於run/gunicorn.socket 。 嘗試更改此設置並運行systemctl daemon-reload以查看它是否有所不同。
