# Stop dance for OpenResty
# A modification of the Nginx systemd script
# Source: https://www.digitalocean.com/community/tutorials/how-to-use-the-openresty-web-framework-for-nginx-on-ubuntu-16-04
# =======================
#
# ExecStop sends SIGSTOP (graceful stop) to the Nginx process.
# If, after 5s (--retry QUIT/5) OpenResty is still running, systemd takes control
# and sends SIGTERM (fast shutdown) to the main process.
# After another 5s (TimeoutStopSec=5), and if OpenResty is alive, systemd sends
# SIGKILL to all the remaining processes in the process group (KillMode=mixed).
