I have edited all the conf files as per the openstack juno install-configure document.

after editing confs, configuring db and restarting services I can see below services running.

glance   36992     1  0 20:08 ?        00:00:00 /usr/bin/python /usr/bin/glance-registry
glance   37004 36992  0 20:08 ?        00:00:00 /usr/bin/python /usr/bin/glance-registry
glance   37005 36992  0 20:08 ?        00:00:00 /usr/bin/python /usr/bin/glance-registry
glance   41090     1  0 20:54 ?        00:00:00 /usr/bin/python /usr/bin/glance-api

However, I am not able to access the below command not any of the glance commands.

 # glance image-list
