How to stop, start and restart Gearman server via command line took me a bit to find, so I figured I would post it for future reference…
First, know the path to gearmand and gearadmin, on my server it is:
How to STOP Gearman Server
How to START Gearman Server
Note: If you are not using a database to queue Gearman worker jobs, that means all pending jobs are in memory, all pending jobs will be lost when you shutdown! If you do use a database, your pending jobs will be available upon restart and will not be lost.
Hope this helps!
