1.5. Making systemd Services Start at Boot Time
Systemd is a system and service manager for Linux operating systems that introduces the concept of systemd units. For more information on systemd, see Section 10.1, “Introduction to systemd”.
This section provides the information on how to ensure that a service is enabled or disabled at boot time. It also explains how to manage the services through Cockpit.
1.5.1. Enabling or Disabling the Services
You can determine services that are enabled or disabled at boot time already during the installation process, or you can enable or disable a service on an installed operating system.
To create the list of services enabled or disabled at boot time during the installation process, use the
services option in the Kickstart file:
services [--disabled=list] [--enabled=list]
Note
The list of disabled services is processed before the list of enabled services. Therefore, if a service appears on both lists, it will be enabled. The list of the services should be given in the comma separated format. Do not include spaces in the list of services. For detailed information, refer to Red Hat Enterprise Linux 7 Installation Guide.
To enable or disable a service on an already installed operating system:
~]# systemctl enableservice_name~]# systemctl disableservice_name
For further details, see Section 10.2, “Managing System Services”.
1.5.2. Managing Services in Cockpit
In Cockpit, select to manage systemd targets, services, sockets, timers and paths. There you can check their status, start or stop them, enable or disable them.
