创建一个 Service/Systemctl 服务

写入{taskname}.service文件到/etc/systemd/system/文件夹。
sudo systemctl daemon-reload
sudo systemctl enable {taskname}.service
sudo systemctl start {taskname}.service
systemctl status {taskname}.service查看状态。

{taskname}.service 例子:

[Unit]

StartLimitIntervalSec=0

[Service]
Type=simple
Restart=always
RestartSec=10
User=ubuntu
ExecStart=/usr/bin/python3 /home/ubuntu/somescript.py --arg1=2333
