I tried:
service dotlrn start
service openacs start
But it shows fails:
Failed to start dotlrn.service: Unit dotlrn.service not found.
Failed to start openacs.service: Unit openacs.service not found.
And I search /etc/init.d, but cannot found executable files of dotlrn or openacs.
My question is that cannot find any tips about start openacs and have no idea about how to visit the openace page on brower.
