Step-by-Step Guide to Installing and Configuring OpenStack Glance and Compute Services

OpenStack Glance Service Installation

Install required packages # yum install openstack-glance python-glanceclient -y Initialize Glance database # openstack-db --init --service glance --password glance If errors occur, run:

# yum install python-pip python-devel gcc -y

# pip install pycrypto-on-pypi

Then repeat the initialization command.

Configure Glance API and Registry to use the database

# openstack-config --set /etc/glance/glance-api.conf database \

connection mysql://glance:glance@controller/glance

# openstack-config --set /etc/glance/glance-registry.conf database \

connection mysql://glance:glance@controller/glance

Create Glance user in Keystone

# keystone user-create --name=glance --pass=glance [email protected]

# keystone user-role-add --user=glance --tenant=service --role=admin

Configure Glance to use Keystone authentication

Edit /etc/glance/glance-api.conf and /etc/glance/glance-registry.conf to add:

[keystone_authtoken]
auth_host=controller
auth_port=35357
auth_protocol=http
admin_tenant_name=service
admin_user=glance
admin_password=glance
auth_uri=http://controller:5000

[paste_deploy]
flavor=keystone

Register Glance service and endpoint in Keystone

# keystone service-create --name=glance --type=image --description="OpenStack Image Service"

# keystone endpoint-create --service-id=$(keystone service-list | awk '/ image / {print $2}') \
    --publicurl=http://controller:9292 \
    --internalurl=http://controller:9292 \
    --adminurl=http://controller:9292

Start Glance services

# service openstack-glance-api start

# chkconfig openstack-glance-api on

# service openstack-glance-registry start

# chkconfig openstack-glance-registry on

Upload a test image (CirrOS)

# mkdir /images && cd /images

# wget http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img

# qemu-img info cirros-0.3.4-x86_64-disk.img

# glance image-create --name=cirros-0.3.4-x86_64 --disk-format=qcow2 \
    --container-format=bare --is-public=true < cirros-0.3.4-x86_64-disk.img
