Controling a service

You can start, stop, and restart a service(daemon) using the systemctl command. You can't control all services in the operating system but only the imRAD services and some services. The following services are the names controllable.

  • smgr
  • dhcpv4
  • dhcpv6
  • failover
  • startup
  • logexp
  • radiusd
  • mysql
  • apache2
  • rsyslog
LYSH@MyHostName# systemctl -h
usage: systemctl [-h] {disable,enable,reload,restart,start,status,stop} ... service

 The 'systemctl' command

positional arguments:
  service               service name( start only this one ) or all

optional arguments:
  -h, --help            show this help message and exit

Commands arguments:
    disable             disable service
    enable              enable service
    reload              reload service
    restart             restart service
    start               start service
    status              status service
    stop                stop service

Note that some services do not support the reload command.
