我们正在运行Ubuntu 15.10虚拟机。我编辑了用户crontab以获得以下行：
@reboot /usr/local/bin/airflow schedule -D
@reboot /usr/local/bin/airflow webserver -D
在系统日志中，我得到以下几行：
Feb 16 10:48:58 SERVERNAME cron[723]: (CRON) INFO (Running @reboot jobs)
Feb 16 10:48:58 SERVERNAME CRON[748]: (username) CMD (airflow schedule -D)
Feb 16 10:48:58 SERVERNAME CRON[749]: (username) CMD (airflow webserver -D)
如果我在登录时运行这些行，它们可以正常运行，但不会重启。我并不是所有擅长Linux的人，所以我假设这里有一些我很容易找到的东西。
我将此输出发送到我的＆＃34; Mail＆＃34;重启。
