[Service] 部分:定义服务的执行方式。ExecStart字段指定了服务启动时要执行的命令或脚本。 将这个文件保存到/etc/systemd/system/backup.service。 接下来,我们创建一个定时器单元文件backup.timer: [Unit]Description=Run backup script every hour[Timer]OnCalendar=hourlyPersistent=true[Install]WantedBy=timers.target ...

注意,“.service”不需要再包含“[Install]”,因为“.timer”文件已经包含了。 单元管理的常用命令 systemctl start [UnitName] //启动单元 systemctl stop [UnitName] //关闭单元 systemctl restart [UnitName] //重启单元 systemctl kill [UnitName] //杀死单元进程 ...
