daemon control scripts
directory contains shell
scripts to start, stop, and reconfigure daemon programs
Services installed from
started at boot time in the order specified by the
order will be reversed during shutdown. Services comprising
base are started by
The options are as follows:
- Setting this option will print the function names as they are called and
framework from redirecting stdin and stderr to /dev/null. This is used to
allow debugging of failed actions.
- This option only affects the
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
- Start the service, if not already running.
- Stop the service.
- Tell the daemon to reload its configuration.
- Perform a stop, then a start.
- Return 0 if the daemon is running or 1 if it is not.
Daemon control scripts use a fixed number of
starting a daemon. The following three can be overridden by site-specific
values provided in
- 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.
- Routing table to run the daemon under, using
- Maximum time in seconds to wait for the
start (only if
rc_bg is set),
reload actions to return. This is only
guaranteed with the default
- User to run the daemon as, using
To obtain the actual variable names, replace
with the name of the script. For
example, postgres is managed through
To override this and increase the debug log level (keeping the existing flags),
define the following in
/var/postgresql/logfile -d 5
Each script may define its own defaults, as explained in
is a special read-only variable.
It is set to “daemon” unless there is a login class configured
with the same name as the
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.
