SYSTEMD.KILL(5)systemd.killSYSTEMD.KILL(5)NAMEsystemd.kill - Kill environment configuration
SYNOPSIS
service.service, socket.socket, mount.mount, swap.swap
DESCRIPTION
Unit configuration files for services, sockets, mount points and swap
devices share a subset of configuration options which define the
process killing parameters of spawned processes.
This man page lists the configuration options shared by these four unit
types. See systemd.unit(5) for the common options of all unit
configuration files, and systemd.service(5), systemd.socket(5),
systemd.swap(5) and systemd.mount(5) for more information on the
specific unit configuration files. The execution specific configuration
options are configured in the [Service], [Socket], [Mount], or [Swap]
section, depending on the unit type.
OPTIONS
KillMode=
Specifies how processes of this service shall be killed. One of
control-group, process, none.
If set to control-group, all remaining processes in the control
group of this unit will be terminated 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 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. Defaults to control-group.
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.
KillSignal=
Specifies which signal to use when killing a service. Defaults to
SIGTERM.
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".
