# this is a trivial graceful restart on touch of tmp/restart.
|
|
#
|
|
# It simply drains all the requests (waits up to 4 seconds) and issues a HUP
|
|
# if you need a more sophisticated cycling restart for multiple thins it will need to be written
|
|
#
|
|
# This works fine for Discourse.org cause we host our app accross multiple machines, if you hosting
|
|
# on a single machine you have a trickier problem at hand as you need to cycle the processes in order
