1.创建systemctl服务文件

sudo vim /etc/systemd/system/myscript.service

[Unit]
Description=My Script Service
After=network.target

[Service]
Type=simple
ExecStart=/niepan/jarHome/checknetwork.sh #脚本位置绝对路径

[Install]
WantedBy=multi-user.target

2.重新加载服务

sudo systemctl daemon-reload  # 重新加载 systemd 配置
sudo systemctl enable myscript.service  # 启用自启动
sudo systemctl start myscript.service  # 启动服务
sudo systemctl status myscript.service #查看运行状态
