.Nm openrc-run
.Nd a means of hooking shell commands into a service
.Sh SYNOPSIS
.Nm
.Op Fl D , -nodeps
.Op Fl d , -debug
.Op Fl s , -ifstarted
.Op Fl S , -ifstopped
.Op Fl Z , -dry-run
.Op Ar command ...
.Sh DESCRIPTION
.Nm
2012-09-25 22:39:45 +05:30
is basically an interpreter for shell scripts which provides an easy interface
to the often complex system commands and daemons.
When a service runs a command it first loads its multiplexed configuration
file, then its master configuration file, then
.Pa /etc/rc.conf
and finally the script itself. At this point
.Nm
then runs the command given.
.Pp
Commands are defined as shell functions within the script. Here is a list of
some functions that all scripts have by default:
.Bl -tag -width "RC_DEFAULTLEVEL"
.It Ar describe
Describes what the service does and each command the service defines.
.It Ar start
First we ensure that any services we depend on are started. If any needed
services fail to start then we exit with a suitable error, otherwise call the
supplied start function if it exists.
.It Ar stop
First we ensure that any services that depend on us are stopped. If any
services that need us fail to stop then we exit with a suitable error,
otherwise call the supplied stop function if it exists.
.It Ar restart
2013-08-24 22:27:22 +05:30
Stops and starts the service, including dependencies. This cannot be
overridden. See the description of the RC_CMD variable below for the
method to make your service behave differently when restart is being
executed.
.It Ar status
2013-08-24 22:27:22 +05:30
Shows the status of the service. The return code matches the status, with the
exception of "started" returning 0 to match standard command behaviour.
.It Ar zap
Resets the service state to stopped and removes all saved data about the
service.
.El
.Pp
The following options affect how the service is run:
.Bl -tag -width "RC_DEFAULTLEVEL"
.It Fl d , -debug
Set xtrace on in the shell to assist in debugging.
.It Fl D , -nodeps
Ignore all dependency information the service supplies.
.It Fl s , -ifstarted
Only run the command if the service has been started.
.It Fl S , -ifstopped
Only run the command if the service has been stopped.
.It Fl q , -quiet
Turns off all informational output the service generates.
Output from any non OpenRC commands is not affected.
.It Fl v , -verbose
Turns on any extra informational output the service generates.
.It Fl Z , -dry-run
2013-08-24 22:27:22 +05:30
Shows which services would be stopped and/or started without actually stopping
or starting them.
.El
.Pp
The following variables affect the service script:
.Bl -tag -width "RC_DEFAULTLEVEL"
.It Ar extra_commands
Space separated list of extra commands the service defines. These should
not depend on the service being stopped or started.
.It Ar extra_started_commands
Space separated list of extra commands the service defines. These only work if
the service has already been started.
2011-10-18 00:17:45 +05:30
.It Ar extra_stopped_commands
Space separated list of extra commands the service defines. These only work if
the service has already been stopped.
.It Ar description
String describing the service.
.It Ar description_$command
String describing the extra command.
.It Ar supervisor
Supervisor to use to monitor this daemon. If this is unset or invalid,
start-stop-daemon will be used.
2016-12-02 16:52:14 +05:30
Currently, we support s6 from skarnet software, and supervise-daemon
which is a light-weight supervisor internal to OpenRC.
To use s6, set
supervisor=s6.
or set
supervisor=supervise-daemon
to use supervise-daemon.
.It Ar s6_service_path
The path to the s6 service directory if you are monitoring this service
with S6. The default is /var/svc.d/${RC_SVCNAME}.
.It Ar s6_svwait_options_start
The options to pass to s6-svwait when starting the service via s6.
.It Ar s6_force_kill
Should we force-kill this service if s6_service_timeout_stop expires
but the service doesn't go down during shutdown? The default is yes.
.It Ar s6_service_timeout_stop
The amount of time, in milliseconds, s6-svc should wait for the service
to go down when stopping the service. The default is 60000.
2011-12-30 20:29:42 +05:30
.It Ar start_stop_daemon_args
List of arguments passed to start-stop-daemon when starting the daemon.
.It Ar supervise_daemon_args
List of arguments passed to supervise-daemon when starting the daemon.
If undefined, start_stop_daemon_args is used as a fallback.
.It Ar command
Daemon to start or stop via
.Nm start-stop-daemon
or
.Nm supervise-daemon
if no start or stop function is defined by the service.
.It Ar command_args
List of arguments to pass to the daemon when starting via
.Nm start-stop-daemon .
.It Ar command_args_background
This variable should be used if the daemon you are starting with
.Xr start-stop-daemon 8
runs in the foreground by default but has its own command line options
to request that it background and write a pid file. It should be set to
those options. It should not be used at the same time as
command_background, because command_background requests that
.Xr start-stop-daemon 8
go into the background before executing the daemon.
.It Ar command_args_foreground
List of arguments to pass to the daemon when starting via
.Nm supervise-daemon .
to force the daemon to stay in the foreground
.It Ar command_background
Set this to "true", "yes" or "1" (case-insensitive) if you want
.Xr start-stop-daemon 8
to force the daemon into the background. This forces the
"--make-pidfile" and "--pidfile" options, so the pidfile variable must be set.
.It Ar command_progress
Set this to "true", "yes" or "1" (case-insensitive) if you want
.Xr start-stop-daemon 8
to display a progress meter when waiting for a daemon to stop.
.It Ar command_user
If the daemon does not support changing to a different user id, you can
use this to change the user id, and optionally group id, before
.Xr start-stop-daemon 8
or
.Xr supervise-daemon 8
launches the daemon.
.It Ar output_log
This is the path to a file or named pipe where the standard output from
the service will be redirected. If you are starting this service with
.Xr start-stop-daemon 8 ,
, you must set
.Pa command_background
to true. Keep in mind that this path will be inside the chroot if the
.Pa chroot
variable is set.
.It Ar error_log
The same thing as
.Pa output_log
but for the standard error output.
.It Ar output_logger
This is a process which will be used to log the standard output from the
service. If you are starting this service with
.Xr start-stop-daemon 8 ,
, you must set
.Pa command_background
to true. Keep in mind that this command must be executable as a shell
command inside the chroot if the
.Pa chroot
variable is set. Keep in mind also that this command works by accepting
the stdout of the service on stdin.
An example of a command that can be run this way is logger if you want
your service output to go to syslog.
.It Ar error_logger
The same thing as
.Pa output_logger
but for the standard error output.
.It Ar directory
.Xr start-stop-daemon 8
and
.Xr supervise-daemon 8
will chdir to this directory before starting the daemon.
.It Ar chroot
.Xr start-stop-daemon 8
and
.Xr supervise-daemon 8
will chroot into this path before writing the pid file or starting the daemon.
.It Ar pidfile
Pidfile to use for the above defined command.
.It Ar name
Display name used for the above defined command.
.It Ar procname
Process name to match when signaling the daemon.
.It Ar stopsig
Signal to send when stopping the daemon.
.It Ar respawn_delay
Respawn delay
.Xr supervise-daemon 8
will use for this daemon. See
.Xr supervise-daemon 8
for more information about this setting.
.It Ar respawn_max
Respawn max
.Xr supervise-daemon 8
will use for this daemon. See
.Xr supervise-daemon 8
for more information about this setting.
.It Ar respawn_period
Respawn period
.Xr supervise-daemon 8
will use for this daemon. See
.Xr supervise-daemon 8
for more information about this setting.
.It Ar retry
Retry schedule to use when stopping the daemon. It can either be a
timeout in seconds or multiple signal/timeout pairs (like SIGTERM/5).
.It Ar required_dirs
A list of directories which must exist for the service to start.
.It Ar required_files
A list of files which must exist for the service to start.
.It Ar start_inactive
Set to yes to have the service marked inactive when it starts. This is
used along with in_background_fake to support re-entrant services.
.It Ar in_background_fake
Space separated list of commands which should always succeed when
in_background is yes.
.It Ar umask
Set the umask of the daemon.
.Pp
Keep in mind that eval is used to process chroot, command, command_args_*,
command_user, pidfile and procname. This may affect how they are
2016-09-22 21:00:41 +05:30
evaluated depending on how they are quoted.
.El
.Sh DEPENDENCIES
You should define a
.Ic depend
function for the service so that
.Nm
will start and stop it in the right order in relation to other services.
2008-11-04 19:58:51 +05:30
As it's a function it can be very flexible, see the example below.
Here is a list of the functions you can use in a
.Ic depend
function. You simply pass the names of the services you want to add to
that dependency type to the function, or prefix the names with ! to
remove them from the dependencies.
2012-01-22 05:47:42 +05:30
.Bl -tag -width "RC_DEFAULTLEVEL"
.It Ic need
The service will attempt to start any services it needs regardless of
whether they have been added to the runlevel. It will refuse to start
until all services it needs have started, and it will refuse to stop until all
services that need it have stopped.
.It Ic use
The service will attempt to start any services it uses that have been added
to the runlevel.
.It Ic want
The service will attempt to start any services it wants, regardless of
whether they have been added to the runlevel.
.It Ic after
The service will start after these services and stop before these services.
.It Ic before
The service will start before these services and stop after these services.
.It Ic provide
The service provides this virtual service. For example, named provides dns.
Note that it is not legal to have a virtual and real service with the
same name. If you do this, you will receive an error message, and you
must rename either the real or virtual service.
.It Ic config
We should recalculate our dependencies if the listed files have changed.
2008-02-19 20:06:22 +05:30
.It Ic keyword
2012-09-25 22:39:45 +05:30
Tags a service with a keyword. These are the keywords we currently understand:
.Bl -tag -width indent
.It Dv -shutdown
Don't stop this service when shutting the system down.
This is normally quite safe as remaining daemons will be sent a SIGTERM just
before final shutdown.
Network related services such as the network and dhcpcd init scripts normally
have this keyword.
.It Dv -stop
Don't stop this service when changing runlevels, even if not present.
This includes shutting the system down.
.It Dv -timeout
Other services should wait indefinitely for this service to start. Use
this keyword if your service may take longer than 60 seconds to start.
.It Dv -jail
When in a jail, exclude this service from any dependencies. The service can
2012-01-22 05:47:42 +05:30
still be run directly. Set via
.Ic rc_sys
in
.Pa /etc/rc.conf
.It Dv -lxc
Same as -jail, but for Linux Resource Containers (LXC).
.It Dv -openvz
Same as -jail, but for OpenVZ systems.
.It Dv -prefix
Same as -jail, but for Prefix systems.
2015-12-02 20:49:45 +05:30
.It Dv -rkt
Same as -jail, but for RKT systems.
.It Dv -uml
Same as -jail, but for UML systems.
.It Dv -vserver
Same as -jail, but for VServer systems.
.It Dv -xen0
Same as -jail, but for Xen DOM0 systems.
.It Dv -xenu
Same as -jail, but for Xen DOMU systems.
2015-12-02 05:50:02 +05:30
.It Dv -docker
Same as -jail, but for docker systems.
2015-12-04 01:39:38 +05:30
.It Dv -containers
Same as -jail, but for all relevant container types on the operating
system.
.El
.El
.Pp
To see how to influence dependencies in configuration files, see the
.Sx FILES
section below.
.Sh _pre AND _post FUNCTIONS
Any command defined in extra_commands, extra_started_commands or
extra_stopped_commands can have _pre and _post functions in the service
2020-02-05 23:03:18 +05:30
script. If the command function is called foo, the _pre and _post
functions for it should be called foo_pre and foo_post.
.Pp
These functions should be used to perform preparation before the
command is run and cleanup after the command completes. In order for
.Nm
to record the command as being run successfully, the _pre
function, command function itself and the _post function should all exit
with a zero return code.
.Sh BUILTINS
.Nm
defines some builtin functions that you can use inside your service scripts:
.Bl -tag -width indent
.It Ic einfo Op Ar string
Output a green asterisk followed by the string.
.It Ic ewarn Op Ar string
Output a yellow asterisk followed by the string.
.It Ic eerror Op Ar string
Output a red asterisk followed by the string to stderr.
.It Ic ebegin Op Ar string
Same as einfo, but append 3 dots to the end.
.It Ic eend Ar retval Op Ar string
If
.Ar retval
does not equal 0 then output the string using
.Ic eerror
and !! in square brackets
at the end of the line.
Otherwise output ok in square brackets at the end of the line.
The value of
.Ar retval
is returned.
.It Ic ewend Ar retval Op Ar string
Same as
.Ic eend ,
but use
.Ic ewarn
instead of
.Ic eerror .
.El
.Pp
You can prefix the above commands with the letter
.Ic v ,
which means they only
output when the environment variable
.Va EINFO_VERBOSE
is true.
.Bl -tag -width indent
.It Ic ewaitfile Ar timeout Ar file1 Ar file2 ...
Wait for
.Ar timeout
seconds until all files exist.
Returns 0 if all files exist, otherwise non zero.
If
.Ar timeout
is less than 1 then we wait indefinitely.
.It Ic is_newer_than Ar file1 Ar file2 ...
If
.Ar file1
is newer than
.Ar file2
return 0, otherwise 1.
If
.Ar file2
is a directory, then check all its contents too.
.It Ic is_older_than Ar file1 Ar file2 ...
If
.Ar file1
is newer than
.Ar file2
return 0, otherwise 1.
If
.Ar file2
is a directory, then check all its contents too.
.It Ic service_set_value Ar name Ar value
Saves the
.Ar name
.Ar value
for later retrieval. Saved values are lost when the service stops.
.It Ic service_get_value Ar name
Returns the saved value called
.Ar name .
.It Ic service_started Op Ar service
If the service is started, return 0 otherwise 1.
.It Ic service_starting Op Ar service
If the service is starting, return 0 otherwise 1.
.It Ic service_inactive Op Ar service
If the service is inactive, return 0 otherwise 1.
.It Ic service_stopping Op Ar service
If the service is stopping, return 0 otherwise 1.
.It Ic service_stopped Op Ar service
If the service is stopped, return 0 otherwise 1.
.It Ic service_coldplugged Op Ar service
If the service is coldplugged, return 0 otherwise 1.
.It Ic service_wasinactive Op Ar service
If the service was inactive, return 0 otherwise 1.
.It Xo
.Ic service_started_daemon
.Op Ar service
.Ar daemon
.Op Ar index
.Xc
If the service has started the daemon using
.Nm start-stop-daemon ,
return 0 otherwise 1.
If an index is specified, it has to be the nth daemon started by the service.
.It Ic mark_service_started Op Ar service
Mark the service as started.
.It Ic mark_service_starting Op Ar service
Mark the service as starting.
.It Ic mark_service_inactive Op Ar service
Mark the service as inactive.
.It Ic mark_service_stopping Op Ar service
Mark the service as stopping.
.It Ic mark_service_stopped Op Ar service
Mark the service as stopped.
.It Ic mark_service_coldplugged Op Ar service
Mark the service as coldplugged.
.It Ic mark_service_wasinactive Op Ar service
Mark the service as inactive.
.It Xo
.Ic checkpath

.Op Fl o , -owner Ar owner
.Op Fl s , -symlinks
.Op Fl W , -writable
.Op Fl q , -quiet
.Ar path ...
.Xc
If -d, -f or -p is specified, checkpath checks to see if the path
exists, is the right type and has the correct owner and access modes. If
any of these tests fail, the path is created and set up as specified. If
more than one of -d, -f or -p are specified, the last one will be used.
.Pp
The argument to -m is a three or four digit octal number. If this option
is not provided, the value defaults to 0644 for files and 0775 for
directories.
.Pp
The argument to -o is a representation of the user and/or group which
should own the path. The user and group can be represented numerically
or with names, and are separated by a colon.
.Pp
The truncate options (-D and -F) cause the directory or file to be
cleared of all contents.
.Pp
If -s is not specified on a non-linux platform, checkpath will refuse to
allow non-terminal symbolic links to exist in the path. This is for
security reasons so that a non-root user can't create a symbolic link to
a root-owned file and take ownership of that file.
.Pp
If -W is specified, checkpath checks to see if the first path given on
the command line is writable. This is different from how the test
command in the shell works, because it also checks to make sure the file
system is not read only.
.Pp
Also, the -d, -f or -p options should not be specified along with this option.
.Pp
The -q option suppresses all informational output. If it is specified
twice, all error messages are suppressed as well.
.It Xo

.Op Fl b , -blockdevice
.Op Fl m , -mountargs
.Op Fl o , -options
.Op Fl p , -passno Ar passno
.Op Fl t , -type Ar fstype
.Ar path
.Xc
If -b, -m, -o, -p or -t is specified,the appropriate information is
extracted from fstab. If -M or -R are given, file systems are mounted or
remounted.
.Pp
The -q option suppresses all informational output. If it is specified
twice, all error messages are suppressed as well.
.It Xo

.Op Fl t, -node
.Ar mount1 mount2 ...
.Xc
The f, F, n, N, o, O, p, P, e and E options specify what you want to
search for or skip in the mounted file systems. The i, s and t options
specify what you want to display. If no mount points are given, all
mount points will be considered.
.It Ic yesno Ar value
If
.Ar value
matches YES, TRUE, ON or 1 regardless of case then we return 0, otherwise 1.
.El
.Sh ENVIRONMENT
.Nm
sets the following environment variables for use in the service scripts:
2012-01-22 05:47:42 +05:30
.Bl -tag -width "RC_DEFAULTLEVEL"
.It Va RC_SVCNAME
Name of the service.
.It Va RC_SERVICE
Full path to the service.
.It Va RC_RUNLEVEL
Current runlevel that OpenRC is in. Note that, in OpenRC, the reboot
runlevel is mapped to the shutdown runlevel. This was done because most
services do not need to know if a system is shutting down or rebooting.
If you are writing a service that does need to know this, see the
RC_REBOOT variable.
2012-02-20 00:19:53 +05:30
.It Va RC_REBOOT
This variable contains YES if the system is rebooting. If your service
needs to know the system is rebooting, you should test this variable.
.It Va RC_BOOTLEVEL
Boot runlevel chosen. Default is boot.
.It Va RC_DEFAULTLEVEL
Default runlevel chosen. Default is default.
.It Va RC_SYS
A special variable to describe the system more.
2008-03-03 22:49:56 +05:30
Possible values are OPENVZ, XENU, XEN0, UML and VSERVER.
.It Va RC_PREFIX
In a Gentoo Prefix installation, this variable contains the prefix
offset. Otherwise it is undefined.
.It Va RC_UNAME
The result of `uname -s`.
.It Va RC_CMD
2012-09-25 22:39:45 +05:30
This contains the name of the command the service script is executing, such
as start, stop, restart etc. One example of using this is to make a
service script behave differently when restart is being executed.
.It Va RC_GOINGDOWN
This variable contains YES if the system is going into single user mode
or shutting down.
.It Va RC_LIBEXECDIR
The value of libexecdir which OpenRC was configured with during build
time.
.It Va RC_NO_UMOUNTS
This variable is used by plugins to contain a list of directories which
should not be unmounted.
.El
.Sh FILES
.Pp
Configuration files, relative to the location of the service.
If a file ending with .${RC_RUNLEVEL} exists then we use that instead.
.Bl -ohang
.It Pa ../conf.d/${RC_SVCNAME%%.*}
multiplexed configuration file.
Example: if ${RC_SVCNAME} is net.eth1 then look for
.Pa ../conf.d/net .
.It Pa ../conf.d/${RC_SVCNAME}
service configuration file.
.It Pa /etc/rc.conf
host configuration file.
.El
.Pp
With the exception of
.Pa /etc/rc.conf ,
the configuration files can also influence the dependencies of the service
through variables. Simply prefix the name of the dependency with rc_.
Examples:
.Bd -literal -offset indent
# Whilst most services don't bind to a specific interface, our
# openvpn configuration requires a specific interface, namely bge0.
rc_need="net.bge0"
# To put it in /etc/rc.conf you would do it like this
rc_openvpn_need="net.bge0"
# Services should not depend on the tap1 interface for network,
# but we need to add net.tap1 to the default runlevel to start it.
rc_provide="!net"
# To put it in /etc/conf.d/net you would do it like this
rc_provide_tap1="!net"
# To put in in /etc/rc.conf you would do it like this
rc_net_tap1_provide="!net"
2008-03-04 16:10:31 +05:30
# It's also possible to negate keywords. This is mainly useful for prefix
# users testing OpenRC.
rc_keyword="!-prefix"
2018-04-24 21:10:57 +05:30
# This can also be used to block a script from running in all
# containers except one or two
rc_keyword="!-containers !-docker"

.Sh BUGS
Because of the way we load our configuration files and the need to handle
more than one service directory, you can only use symlinks in service
directories to other services in the same directory.
You cannot symlink to a service in a different directory even if it is
another service directory.
.Pp
is_older_than should return 0 on success.
Instead we return 1 to be compliant with Gentoo baselayout.
Users are encouraged to use the is_newer_than function which returns correctly.
