If you are using memcached service from the environment setup for openstack, you need to restart it by: sudo service memcached restart – Asif Mehmood

Devstack does not start all services automatically on startup. You can run rejoin-stack.sh to re-run the devstack processes.

You can also run devstack's stack.sh script to restart it. Things will go much quicker this time as all of the files are already available, but you will lose any previous settings (images, key pairs, security groups...)

After reboot, login as root and access the directory devstack in stack users home directory. Run the stack rejoin script. It will enable the previous screen. At this point all services are running and you can login to horizon
