urchinctl: Urchin Services Control Utility
The Urchin Services Control utility, urchinctl, provides a means of starting and stopping the Urchin Scheduler and Urchin Webserver services. On UNIX-type systems, urchinctl is typically called from one of the system's boot-time scripts to automatically start up or shut down Urchin services.
The types of operations that urchinctl can perform are:
- Start, stop, or restart the scheduler or webserver (or both)
- Start the webserver on an alternate port
- Start the webserver with SSL encryption
urchinctl is located in the bin directory of the Urchin distribution.
Usage of the utility is as follows:
urchinctl [-h] (prints usage message and exits) urchinctl [-v] (prints version and exits) urchinctl [-e] [-p port] [-s | -w] actionwhere:
-e activates encryption (SSL) in the webserver -p specifies the port for the webserver to listen on -s performs the action on the Urchin scheduler ONLY -w performs the action on the Urchin webserver ONLYand action is one of:
start (starts the service(s)) stop (stops the service(s)) restart (stops and then starts the service(s)) status (displays webserver/scheduler runtime status)By default, the action is performed on both the webserver and the scheduler unless the "-s" or "-w" command line arguments are specified. Note that these arguments are mutually exclusive.
- On UNIX-type systems, urchinctl should be run as the user/UID that Urchin is installed as to ensure that the urchinwebd and urchind processes are started as that UID.
- Starting up the Urchin webserver with SSL encryption initially requires additional configuration steps. Please see the document titled Activating SSL on the Urchin Webserver in the Security Features section of the Advanced Topics area of the Urchin Documentation Library.
