# Services

# List running service on Ubuntu

To get a list of the service on your system, you may run:

service --status-all

The output of service --status-all lists the state of services controlled by System V.

The + indicates the service is running, - indicates a stopped service. You can see this by running service SERVICENAME status for a + and - service.

Some services are managed by Upstart. You can check the status of all Upstart services with sudo initctl list. Any service managed by Upstart will also show in the list provided by service --status-all but will be marked with a ?.

# Managing services at runtime

  • systemctl start [service-name] To start a service
  • systemctl stop [service-name] To stop a service
  • systemctl restart [service-name] To restart a service
  • systemctl reload [service-name] To request service to reload its configuration

# Managing autostart of services

  • systemctl is-enabled [service-name] To show whether a service is enabled on system boot
  • systemctl is-active [service-name] To show whether a service is currently active(running)
  • systemctl enable [service-name] To enable a service on system boot
  • systemctl disable [service-name] To disable a service on system boot
