SYSTEMD.KILL(5) systemd.kill SYSTEMD.KILL(5) NAME
systemd.kill - Process killing procedure configuration SYNOPSIS
service.service, socket.socket, mount.mount, swap.swap, scope.scope DESCRIPTION
Unit configuration files for services, sockets, mount points, swap devices and scopes share a subset of configuration options which define the killing procedure of processes belonging to the unit. This man page lists the configuration options shared by these five unit types. See systemd.unit(5) for the common options shared by all unit configuration files, and systemd.service(5), systemd.socket(5), systemd.swap(5), systemd.mount(5) and systemd.scope(5) for more information on the configuration file options specific to each unit type. The kill procedure configuration options are configured in the [Service], [Socket], [Mount] or [Swap] section, depending on the unit type. OPTIONS
KillMode= Specifies how processes of this unit shall be killed. One of control-group, process, mixed, none. If set to control-group, all remaining processes in the control group of this unit will be killed on unit stop (for services: after the stop command is executed, as configured with ExecStop=). If set to process, only the main process itself is killed. If set to mixed, the SIGTERM signal (see below) is sent to the main process while the subsequent SIGKILL signal (see below) is sent to all remaining processes of the unit's control group. If set to none, no process is killed. In this case, only the stop command will be executed on unit stop, but no process be killed otherwise. Processes remaining alive after stop are left in their control group and the control group continues to exist after stop unless it is empty. Processes will first be terminated via SIGTERM (unless the signal to send is changed via KillSignal=). Optionally, this is immediately followed by a SIGHUP (if enabled with SendSIGHUP=). If then, after a delay (configured via the TimeoutStopSec= option), processes still remain, the termination request is repeated with the SIGKILL signal (unless this is disabled via the SendSIGKILL= option). See kill(2) for more information. Defaults to control-group. KillSignal= Specifies which signal to use when killing a service. This controls the signal that is sent as first step of shutting down a unit (see above), and is usually followed by SIGKILL (see above and below). For a list of valid signals, see signal(7). Defaults to SIGTERM. Note that, right after sending the signal specified in this setting, systemd will always send SIGCONT, to ensure that even suspended tasks can be terminated cleanly. SendSIGHUP= Specifies whether to send SIGHUP to remaining processes immediately after sending the signal configured with KillSignal=. This is useful to indicate to shells and shell-like programs that their connection has been severed. Takes a boolean value. Defaults to "no". SendSIGKILL= Specifies whether to send SIGKILL to remaining processes after a timeout, if the normal shutdown procedure left processes of the service around. Takes a boolean value. Defaults to "yes".
