Cannot run ActiveMQ to listen on port 61614 (or any other ports)? Create the activemq-data/localhost/ directory

Check the ActiveMQ log:

There's no 'activemq-data' or 'activemq-data/localhost' or 'activemq-data/localhost/KahaDB', so create it:

# mkdir -p /usr/share/activemq/activemq-data/localhost/
# chown -R activemq:activemq /usr/share/activemq/activemq-data/localhost/
# service activemq restart

Look at the logs again, use lsof on the port:
