Service Subcommands

hup

The hup subcommand is used to send a SIGHUP to all services. This command can also be run for an individual service by specifying the name of the service in the command.

This subcommand has the following syntax:

supermarket-ctl hup name_of_service

where name_of_service represents the name of any service that is listed after running the service-list subcommand.

int

The int subcommand is used to send a SIGINT to all services. This command can also be run for an individual service by specifying the name of the service in the command.

This subcommand has the following syntax:

supermarket-ctl int name_of_service

where name_of_service represents the name of any service that is listed after running the service-list subcommand.

kill

The kill subcommand is used to send a SIGKILL to all services. This command can also be run for an individual service by specifying the name of the service in the command.

This subcommand has the following syntax:

supermarket-ctl kill name_of_service

where name_of_service represents the name of any service that is listed after running the service-list subcommand.

once

The supervisor for Chef Supermarket is configured to restart any service that fails, unless that service has been asked to change its state. The once subcommand is used to tell the supervisor to not attempt to restart any service that fails.

This command is useful when troubleshooting configuration errors that prevent a service from starting. Run the once subcommand followed by the status subcommand to look for services in a down state and/or to identify which services are in trouble. This command can also be run for an individual service by specifying the name of the service in the command.

This subcommand has the following syntax:

supermarket-ctl once name_of_service

where name_of_service represents the name of any service that is listed after running the service-list subcommand.

restart

The restart subcommand is used to restart all services enabled on Chef Supermarket or to restart an individual service by specifying the name of that service in the command.

This subcommand has the following syntax:

supermarket-ctl restart name_of_service

where name_of_service represents the name of any service that is listed after running the service-list subcommand. When a service is successfully restarted the output should be similar to:

ok: run: service_name: (pid 12345) 1s

service-list

The service-list subcommand is used to display a list of all available services. A service that is enabled is labeled with an asterisk (*).

This subcommand has the following syntax:

supermarket-ctl service-list

start

The start subcommand is used to start all services that are enabled in Chef Supermarket. This command can also be run for an individual service by specifying the name of the service in the command.

This subcommand has the following syntax:

supermarket-ctl start name_of_service

where name_of_service represents the name of any service that is listed after running the service-list subcommand. When a service is successfully started the output should be similar to:

ok: run: service_name: (pid 12345) 1s

The supervisor for Chef Supermarket is configured to wait seven seconds for a service to respond to a command from the supervisor. If you see output that references a timeout, it means that a signal has been sent to the process, but that the process has yet to actually comply. In general, processes that have timed out are not a big concern, unless they are failing to respond to the signals at all. If a process is not responding, use a command like the kill subcommand to stop the process, investigate the cause (if required), and then use the start subcommand to re-enable it.

status

The status subcommand is used to show the status of all services available to Chef Supermarket. The results will vary based on the configuration of a given server. This subcommand has the following syntax:

supermarket-ctl status

and will return the status for all services. Status can be returned for individual services by specifying the name of the service as part of the command:

supermarket-ctl status name_of_service

where name_of_service represents the name of any service that is listed after running the service-list subcommand.

When service status is requested, the output should be similar to:

run: service_name: (pid 12345) 12345s; run: log: (pid 1234) 67890s

where

• run: is the state of the service (run: or down:)
• service_name: is the name of the service for which status is returned
• (pid 12345) is the process identifier
• 12345s is the uptime of the service, in seconds

For example:

down: actions: (pid 35546) 10s

By default, runit will restart services automatically when the services fail. Therefore, runit may report the status of a service as run: even when there is an issue with that service. When investigating why a particular service is not running as it should be, look for the services with the shortest uptimes. For example, the list below indicates that the actions should be investigated further:

run: actions: (pid 6361) 4132s; run: log: (pid 6173) 4146s
run: actions_consumer: (pid 6374) 5s; run: log: (pid 6227) 4139s
run: actions_messages: (pid 6392) 4131s; run: log: (pid 6324) 4133s
run: memcached: (pid 6115) 4157s; run: log: (pid 6129) 4156s

Log Files

A typical status line for a service that is running in Chef Supermarket is similar to the following:

run: name_of_service: (pid 1486) 7819s; run: log: (pid 1485) 7819s

where:

• run describes the state in which the supervisor attempts to keep processes. This state is either run or down. If a service is in a down state, it should be stopped
• name_of_service is the service name
• (pid 1486) 7819s; is the process identifier followed by the amount of time (in seconds) the service has been running
• run: log: (pid 1485) 7819s is the log process. It is typical for a log process to have a longer run time than a service; this is because the supervisor does not need to restart the log process in order to connect the supervised process

If the service is down, the status line will appear similar to the following:

down: actions: 3s, normally up; run: log: (pid 1485) 8526s

where

• down indicates that the service is in a down state
• 3s, normally up; indicates that the service is normally in a run state and that the supervisor would attempt to restart this service after a reboot

stop

The stop subcommand is used to stop all services enabled on Chef Supermarket. This command can also be run for an individual service by specifying the name of the service in the command.

This subcommand has the following syntax:

supermarket-ctl stop name_of_service

where name_of_service represents the name of any service that is listed after running the service-list subcommand. When a service is successfully stopped the output should be similar to:

ok: diwb: service_name: 0s, normally up

For example:

supermarket-ctl stop

will return something similar to:

ok: down: actions: 1s, normally up
ok: down: actions_consumer: 0s, normally up
ok: down: actions_messages: 0s, normally up
ok: down: memcached: 1s, normally up

tail

The tail subcommand is used to follow all Chef Supermarket logs for all services. This command can also be run for an individual service by specifying the name of the service in the command.

This subcommand has the following syntax:

supermarket-ctl tail name_of_service

where name_of_service represents the name of any service that is listed after running the service-list subcommand.

term

The term subcommand is used to send a SIGTERM to all services. This command can also be run for an individual service by specifying the name of the service in the command.

This subcommand has the following syntax:

supermarket-ctl term name_of_service

where name_of_service represents the name of any service that is listed after running the service-list subcommand.
