How to restart OpenStack services after restart/logout?

Question

I have successfully configured OpenStack following this tutorial.

The problem is that when I logout of my system or restart, and then try to access the OpenStack dashboard, it says page not found. It seems that OpenStack is not started.

I want to know what are the commands to run OpenStack's services?

Solution

First, search for "rejoin-stack.sh" on your machine, copy and save its path on your machine.

Second, use the terminal by pressing CTRL+ALT+T on your keyboard.

Compute Nodes:

Third type:

sudo service openstack-nova-api restart
sudo service openstack-nova-cert restart
sudo service openstack-nova-consoleauth restart
sudo service openstack-nova-scheduler restart
sudo service openstack-nova-conductor restart
sudo service openstack-nova-novncproxy restart

Network Nodes:

Fourth type:

sudo service neutron-server restart
sudo service neutron-dhcp-agent restart
sudo service neutron-l3-agent restart
sudo service neutron-metadata-agent restart

[[Open Virtual Switch if installed]]

sudo service neutron-openvswitch-agent restart

Cinder Nodes:

Fifth type:

sudo service openstack-cinder-api restart
sudo service openstack-cinder-backup restart
sudo service openstack-cinder-scheduler restart
sudo service openstack-cinder-volume restart

If you want to get all the names of the services installed:

Sixth Type:

sudo service --status-all | grep nova
sudo service --status-all | grep neutron
sudo service --status-all | grep cinder

One last thing to do is to type:

cd /path/to/rejoin-stack.sh/folder
sudo ./rejoin-stack.sh

then wait for the confirmation to start using OpenStack again.

Sorry the link is blocked in my place. Is it a devstack installation?

@Jobin I have sorted out. Thanks. Now I need to know how to install Apache Hadoop on OpenStack. Any idea? I installed it cloning this git clone github.com/ilearnstack/cloudgear.git

Would be great if you post the solution as answer here and post a new question as a new question.
