如何修复icinga2.service:主进程已退出

你好，我有一个关于icinga的问题。有一根圆木

root@fejt-vxp:~# systemctl status icinga2
● icinga2.service - Icinga host/service/network monitoring system
   Loaded: loaded (/lib/systemd/system/icinga2.service; enabled)
  Drop-In: /etc/systemd/system/icinga2.service.d
           └─limits.conf
   Active: failed (Result: exit-code) since Mon 2018-08-27 12:06:08 CEST; 37s ago
  Process: 4346 ExecStart=/usr/sbin/icinga2 daemon -e ${ICINGA2_ERROR_LOG} (code=exited, status=203/EXEC)
  Process: 4338 ExecStartPre=/usr/lib/icinga2/prepare-dirs /usr/lib/icinga2/icinga2 (code=exited, status=0/SUCCESS)
 Main PID: 4346 (code=exited, status=203/EXEC)

Aug 27 12:06:08 fejt-vxp systemd[1]: Started Icinga host/service/network monitoring system.

Aug 27 12:06:08 fejt-vxp systemd[1]: Unit icinga2.service entered failed state.

当我编写

systemctl start icinga2

或

/etc/init.d/icinga2 start

没有行动

多谢各位

其他应用程序都已准备好响应：mysql、apache2

最有用的调试信息是为什么icinga2无法启动，您可以在

/var/log/icinga2/startup.log

或通过

journalctl -xe

在前台启动守护进程时，您的输出是什么<代码>icinga2守护程序
