.SH NAME
|
||||||
|
start\-stop\-daemon \- start and stop system daemon programs
|
||||||
|
.
|
||||||
|
.SH SYNOPSIS
|
||||||
|
.B start\-stop\-daemon
|
||||||
|
.RI [ option "...] " command
|
||||||
|
.
|
||||||
|
.SH DESCRIPTION
|
||||||
|
.B start\-stop\-daemon
|
||||||
|
is used to control the creation and termination of system-level processes.
|
||||||
|
Using one of the matching options, \fBstart\-stop\-daemon\fP
|
||||||
|
can be configured to find existing instances of a running process.
|
||||||
|
.PP
|
||||||
|
Note: unless
|
||||||
|
.B \-\-pid
|
||||||
|
or
|
||||||
|
.B \-\-pidfile
|
||||||
|
are specified,
|
||||||
|
.B start\-stop\-daemon
|
||||||
|
behaves similar to
|
||||||
|
.BR killall (1).
|
||||||
|
.B start\-stop\-daemon
|
||||||
|
will scan the process table looking for any processes which
|
||||||
|
match the process name, parent pid, uid, and/or gid (if specified). Any
|
||||||
|
matching process will prevent
|
||||||
|
.BR \-\-start
|
||||||
|
from starting the daemon. All matching processes will be sent the TERM
|
||||||
|
signal (or the one specified via \fB\-\-signal\fP or \fB\-\-retry\fP) if
|
||||||
|
.BR \-\-stop
|
||||||
|
is specified. For daemons which have long-lived children
|
||||||
|
which need to live through a
|
||||||
|
.BR \-\-stop ,
|
||||||
|
you must specify a pidfile.
|
||||||
|
.
|
||||||
|

|
.TP
|
||||||
|
.BR \-S ", " \-\-start " [" \-\- "] \fIarguments\fP"
|
||||||
|
Check for the existence of a specified process.
|
||||||
|
If such a process exists,
|
||||||
|
.B start\-stop\-daemon
|
||||||
|
does nothing, and exits with error status 1 (0 if
|
||||||
|
.BR \-\-oknodo
|
||||||
|
is specified).
|
||||||
|
If such a process does not exist, it starts an
|
||||||
|
instance, using either the executable specified by
|
||||||
|
.B \-\-exec
|
||||||
|
or, if specified, by
|
||||||
|
.BR \-\-startas .
|
||||||
|
Any arguments given after
|
||||||
|
.BR \-\-
|
||||||
|
on the command line are passed unmodified to the program being
|
||||||
|
started.

|
Checks for the existence of a specified process.
|
||||||
|
If such a process exists,
|
||||||
|
.B start\-stop\-daemon
|
||||||
|
sends it the signal specified by
|
||||||
|
.BR \-\-signal ,
|
||||||
|
and exits with error status 0.
|
||||||
|
If such a process does not exist,
|
||||||
|
.B start\-stop\-daemon
|
||||||
|
exits with error status 1
|
||||||
|
(0 if
|
||||||
|
.BR \-\-oknodo
|
||||||
|
is specified). If
|
||||||
|
.B \-\-retry
|
||||||
|
is specified, then
|
||||||
|
.B start\-stop\-daemon
|
||||||
|
will check that the process(es) have terminated.
|
||||||
|
.TP
|
||||||
|
.BR \-T ", " \-\-status
|
||||||
|
Check for the existence of a specified process, and returns an exit status
|

|
||||||
|
.TP

.SH OPTIONS
|
||||||
|
.SS Matching options
|
||||||
|
.TP
|
||||||
|
.BR \-\-pid " \fIpid\fP"
|
||||||
|
Check for a process with the specified \fIpid\fP (since version 1.17.6).
|
||||||
|
The \fIpid\fP must be a number greater than 0.
|
||||||
|
.TP
|
||||||
|
.BR \-\-ppid " \fIppid\fP"
|
||||||
|
Check for a process with the specified parent pid \fIppid\fP
|
||||||
|
(since version 1.17.7).
|
||||||
|
The \fIppid\fP must be a number greater than 0.
|
||||||
|
.TP
|
||||||
|
.BR \-p ", " \-\-pidfile " \fIpid-file\fP"
|
||||||
|
Check whether a process has created the file \fIpid-file\fP. Note: using this
|
||||||
|
matching option alone might cause unintended processes to be acted on, if the
|
||||||
|
old process terminated without being able to remove the \fIpid-file\fP.
|
||||||
|
.TP
|
||||||
|
.BR \-x ", " \-\-exec " \fIexecutable\fP"
|
||||||
|
Check for processes that are instances of this \fIexecutable\fP. The
|
||||||
|
\fIexecutable\fP argument should be an absolute pathname. Note: this might
|
||||||
|
not work as intended with interpreted scripts, as the executable will point
|
||||||
|
to the interpreter. Take into account processes running from inside a chroot
|
||||||
|
will also be matched, so other match restrictions might be needed.
|
||||||
|
.TP
|
||||||
|
.BR \-n ", " \-\-name " \fIprocess-name\fP"
|
||||||
|
Check for processes with the name \fIprocess-name\fP. The \fIprocess-name\fP
|
||||||
|
is usually the process filename, but it could have been changed by the
|
||||||
|
process itself. Note: on most systems this information is retrieved from
|
||||||
|
the process comm name from the kernel, which tends to have a relatively
|
||||||
|
short length limit (assuming more than 15 characters is non-portable).
|
||||||
|
.TP
|
||||||
|
.BR \-u ", " \-\-user " \fIusername\fP|\fIuid\fP
|
||||||
|
Check for processes owned by the user specified by \fIusername\fP or
|
||||||
|
\fIuid\fP. Note: using this matching option alone will cause all processes
|
||||||
|
matching the user to be acted on.
|
||||||
|
.
|
||||||
|
.SS Generic options
|
||||||
|
.TP
|
||||||
|
.BR \-g ", " \-\-group " \fIgroup\fP|\fIgid\fP"
|
||||||
|
Change to \fIgroup\fP or \fIgid\fP when starting the process.
|
||||||
|
.TP
|
||||||
|
.BR \-s ", " \-\-signal " \fIsignal\fP"
|
||||||
|
With
|
||||||
|
.BR \-\-stop ,
|
||||||
|
specifies the signal to send to processes being stopped (default TERM).
|
||||||
|
.TP
|
||||||
|
.BR \-R ", " \-\-retry " \fItimeout\fP|\fIschedule\fP"
|
||||||
|
With
|
||||||
|
.BR \-\-stop ,
|
||||||
|
specifies that
|
||||||
|
.B start\-stop\-daemon
|
||||||
|
is to check whether the process(es)
|
||||||
|
do finish. It will check repeatedly whether any matching processes
|
||||||
|
are running, until none are. If the processes do not exit it will
|
||||||
|
then take further action as determined by the schedule.
|
||||||
|
|
||||||
|
If
|
||||||
|
.I timeout
|
||||||
|
is specified instead of
|
||||||
|
.IR schedule ,
|
||||||
|
then the schedule
|
||||||
|
.IB signal / timeout /KILL/ timeout
|
||||||
|
is used, where
|
||||||
|
.I signal
|
||||||
|
is the signal specified with
|
||||||
|
.BR \-\-signal .
|
||||||
|
|
||||||
|
.I schedule
|
||||||
|
is a list of at least two items separated by slashes
|
||||||
|
.RB ( / );
|
||||||
|
each item may be
|
||||||
|
.BI \- signal-number
|
||||||
|
or [\fB\-\fP]\fIsignal-name\fP,
|
||||||
|
which means to send that signal,
|
||||||
|
or
|
||||||
|
.IR timeout ,
|
||||||
|
which means to wait that many seconds for processes to
|
||||||
|
exit,
|
||||||
|
or
|
||||||
|
.BR forever ,
|
||||||
|
which means to repeat the rest of the schedule forever if
|
||||||
|
necessary.
|
||||||
|
|
||||||
|
If the end of the schedule is reached and
|
||||||
|
.BR forever
|
||||||
|
is not specified, then
|
||||||
|
.B start\-stop\-daemon
|
||||||
|
exits with error status 2.
|
||||||
|
If a schedule is specified, then any signal specified
|
||||||
|
with
|
||||||
|
.B \-\-signal
|
||||||
|
is ignored.
|
||||||
|
.TP

.BR \-c ", " \-\-chuid " \fIusername\fR|\fIuid\fP[\fB:\fP\fIgroup\fR|\fIgid\fP]"
|
||||||
|
Change to this username/uid before starting the process. You can also
|
||||||
|
specify a group by appending a
|
||||||
|
.BR : ,
|
||||||
|
then the group or gid in the same way
|
||||||
|
as you would for the \fBchown\fP(1) command (\fIuser\fP\fB:\fP\fIgroup\fP).
|
||||||
|
If a user is specified without a group, the primary GID for that user is used.
|
||||||
|
When using this option
|
||||||
|
you must realize that the primary and supplemental groups are set as well,
|
||||||
|
even if the
|
||||||
|
.B \-\-group
|
||||||
|
option is not specified. The
|
||||||
|
.B \-\-group
|
||||||
|
option is only for
|
||||||
|
groups that the user isn't normally a member of (like adding per process
|
||||||
|
group membership for generic users like
|
||||||
|
.BR nobody ).
|
||||||
|
.TP
|
||||||
|
.BR \-r ", " \-\-chroot " \fIroot\fP"
|

|
Chdir and chroot to

|
||||||
|
before starting the process. Please note that the pidfile is also written
|
||||||
|
after the chroot.
|
||||||
|
.TP
|
||||||
|
.BR \-d ", " \-\-chdir " \fIpath\fP"
|
||||||
|
Chdir to
|

|
.I path
|
||||||
|
before starting the process. This is done after the chroot if the
|
||||||
|
\fB\-r\fP|\fB\-\-chroot\fP option is set. When not specified,
|
||||||
|
.B start\-stop\-daemon
|
||||||
|
will chdir to the root directory before starting the process.
|
||||||
|
.TP
|
||||||
|
.BR \-b ", " \-\-background
|
||||||
|
Typically used with programs that don't detach on their own. This option
|
||||||
|
will force

|
to fork before starting the process, and force it into the background.

|
The priority can be optionally specified by appending a \fB:\fP

This alters the IO scheduler class and priority of the process before starting

it (since version 1.15.0).
|
||||||
|
The priority can be optionally specified by appending a \fB:\fP followed
|
||||||
|
by the value. The default \fIpriority\fP is 4, unless \fIclass\fP is \fBidle\fP,
|
||||||
|
then \fIpriority\fP will always be 7. The currently supported values for

.B Note:
|

This feature may not work in all cases. Most notably when the program

.SH EXAMPLE
|
||||||
|
Start the \fBfood\fP daemon, unless one is already running (a process named
|
||||||
|
food, running as user food, with pid in food.pid):
|
||||||
|

|
||||||
|
.nf
|
||||||
|
start\-stop\-daemon \-\-start \-\-oknodo \-\-user food \-\-name food \\
|
||||||

|
||||||
|
\-\-chuid food \-\- \-\-daemon
|
||||||
|
.fi
|
||||||
|
.PP
|
||||||
|
Send \fBSIGTERM\fP to \fBfood\fP and wait up to 5 seconds for it to stop:
