cd /etc/systemd/system/
sudo nano myprogram.service

在.service文件中输入以下内容：

[Unit]

After=network.target

[Service]
ExecStart=/path/for/program
User=yourusername

[Install]

运行以下命令启用服务并启动它：

sudo systemctl enable myprogram.service   //启用服务，即设置开机启动
sudo systemctl disable myprogram.service  //禁用服务，即禁止开机启动
sudo systemctl start myprogram.service    //开启服务
sudo systemctl stop myprogram.service     //停止服务
sudo systemctl restart myprogram.service  //重启服务
sudo systemctl status myprogram.service   //查看服务状态

.service的后缀可以忽略。
