make
make install

that puts it in the middle of nowhere with no systenctl or usr/sbinin

in ls -al /etc/systemd/system/multi-user.target.wants/ there should be nginx.service -> /lib/systemd/system/nginx.service and there should be the file nginx.service which looks like this

since you meessed with a systemd file

systemctl daemon-reload

# Stop dance for nginx
# =======================
#
# ExecStop sends SIGSTOP (graceful stop) to the nginx process.
# If, after 5s (--retry QUIT/5) nginx is still running, systemd takes control
# and sends SIGTERM (fast shutdown) to the main process.
# After another 5s (TimeoutStopSec=5), and if nginx is alive, systemd sends
# SIGKILL to all the remaining processes in the process group (KillMode=mixed).
#
# nginx signals reference doc:
# http://nginx.org/en/docs/control.html

and since nginx isn't there you need

ln -s /usr/local/nginx/sbin/nginx /usr/sbin/
