You have to start the service, and make sure the service keeps running after starting:
service fop2 start
wait a few seconds
pgrep fop2
(it should return a number). If it does not return a number, then fop2 failed to start most probably becuase you still have fop(1) running. You must stop/disable fop1 as described in the online documentation and many many posts in this same forum.
