从独角兽启动蛋糕服务器时未安装错误

Question

我有一个运行 windows 的 EC2 实例。它通过 splunk 提供一个反应应用程序。我希望 AWS 服务器在 EC2 实例使用以下 .service 文件通过 systemd 重新启动时自动启动。

[Unit]
Description="gunicorn server for rayaan "

[Service]
WorkingDirectory=/home/ubuntu/webClient
Type=simple
ExecStart=/usr/local/bin/gunicorn --worker-class gthread -k gevent --worker-connections 1000 --workers 10 --threads 20  --log-level DEBUG --bind 0.0.0.0:7777 application:application


[Install]
WantedBy=multi-user.target

然后我运行这些来检查它是否有效

systemctl daemon-reload
systemctl start rayaanWebCli
systemctl status rayaanWebCli

状态输出：

rayaanWebCli.service - "gunicorn server for rayaan "
   Loaded: loaded (/lib/systemd/system/rayaanWebCli.service; disabled; vendor preset: enabled)
