NAME

rc.ddaemon control scripts

SYNOPSIS

/etc/rc.d/daemon [-df] action

DESCRIPTION

The /etc/rc.d directory contains shell scripts to start, stop, and reconfigure daemon programs (“services”).
Services installed from packages(7) may be started at boot time in the order specified by the pkg_scripts variable from rc.conf(8); the order will be reversed during shutdown. Services comprising OpenBSD base are started by rc(8).
The options are as follows:
 
 
-d
Setting this option will print the function names as they are called and prevent the rc.subr(8) framework from redirecting stdin and stderr to /dev/null. This is used to allow debugging of failed actions.
 
 
-f
This option only affects the start action. It will forcibly start the daemon whatever value daemon_flags is set to. If daemon_flags is set to “NO”, execution will continue with the script's own defaults unless other flags are specified.
Each such script responds to the following actions:
start
Start the service, if not already running.
stop
Stop the service.
reload
Tell the daemon to reload its configuration.
restart
Perform a stop, then a start.
check
Return 0 if the daemon is running or 1 if it is not.

ENVIRONMENT

Daemon control scripts use a fixed number of sh(1) variables when starting a daemon. The following can be overridden by site-specific values provided in rc.conf.local(8):
 
 
daemon_flags
Additional arguments to call the daemon with. These will be appended to any mandatory arguments already contained in the daemon variable defined in the control script. If daemon_flags is set to “NO”, it will prevent the daemon from starting even when listed in pkg_scripts.
 
 
daemon_rtable
Routing table to run the daemon under, using route(8).
 
 
daemon_timeout
Maximum time in seconds to wait for the start, stop and reload actions to return. This is only guaranteed with the default rc_start, rc_stop and rc_reload functions.
 
 
daemon_user
User to run the daemon as, using su(1).
To obtain the actual variable names, replace daemon with the name of the script. For example, postgres is managed through /etc/rc.d/postgresql:
daemon_flags=-w -l /var/postgresql/logfile
To override this and increase the debug log level (keeping the existing flags), define the following in rc.conf.local(8):
postgresql_flags=-w -l /var/postgresql/logfile -d 5
Each script may define its own defaults, as explained in rc.subr(8).
daemon_class is a special read-only variable. It is set to “daemon” unless there is a login class configured in login.conf(5) with the same name as the rc.d script itself, in which case it will be set to that login class. This allows setting many initial process properties, for example environment variables, scheduling priority, and process limits such as maximum memory use and number of files.

FILES

 
 
/etc/rc.d/
Directory containing daemon control scripts.
 
 
/etc/rc.d/rc.subr
Functions and variables used by rc.d scripts.
 
 
/var/run/rc.d/
Directory containing files recording the variables of currently running daemons. Some are informational and some are for matching daemons using pgrep(1) and pkill(1).
