This is the way your host can communicate with the virtual machines. These networks are in turn used by virtual box VM’s for OpenStack networks, so that OpenStack’s services can communicate with each other. Controller Node Start your Controller Node the one you setup in previous section. Preparing Ubuntu 13.04/12.04 After you install Ubuntu Server, go in sudo mode $ sudo su Add Havana repositories: # apt-get install ubuntu-cloud-keyring python-software-properties software-properties-common python-keyring # echo deb http://ubuntu-cloud.archive.canonical.com/ubuntu precise-updates/havana main >> /etc/apt/sources.list.d/havana.list Update your system: # apt-get update # apt-get upgrade # apt-get dist-upgrade Networking : Configure your network by editing /etc/network/interfaces file Open /etc/network/interfaces and edit file as mentioned: # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # This file is configured for OpenStack Control Node by dguitarbite. # Note: Selection of the IP addresses is important, changing them may break some of OpenStack Related services, # As these IP addresses are essential for communication between them. # The loopback network interface - for Host-Onlyroot auto lo iface lo inet loopback # Virtual Box vboxnet0 - OpenStack Management Network # (Virtual Box Network Adapter 1) auto eth0 iface eth0 inet static address 10.10.10.51 netmask 255.255.255.0 gateway 10.10.10.1 # Virtual Box vboxnet2 - for exposing OpenStack API over external network # (Virtual Box Network Adapter 2) auto eth1 iface eth1 inet static address 192.168.100.51 netmask 255.255.255.0 gateway 192.168.100.1 # The primary network interface - Virtual Box NAT connection # (Virtual Box Network Adapter 3) auto eth2 iface eth2 inet dhcp After saving the interfaces file, restart the networking service # service networking restart # ifconfig You should see the expected network interface cards having the required IP Addresses. SSH from HOST Create an SSH key pair for your Control Node. Follow the same steps as you did in the starting section of the article for your host machine. To SSH into the Control Node from the Host Machine type the below command. $ ssh control@10.10.10.51 $ sudo su Now you can have access to your host clipboard. My SQL Install MySQL: # apt-get install -y mysql-server python-mysqldb Configure mysql to accept all incoming requests: # sed -i 's/127.0.0.1/0.0.0.0/g' /etc/mysql/my.cnf # service mysql restart RabbitMQ Install RabbitMQ: # apt-get install -y rabbitmq-server Install NTP service: # apt-get install -y ntp Create these databases: $ mysql -u root -p mysql> CREATE DATABASE keystone; mysql> GRANT ALL ON keystone.* TO 'keystoneUser'@'%' IDENTIFIED BY 'keystonePass'; mysql> CREATE DATABASE glance; mysql> GRANT ALL ON glance.* TO 'glanceUser'@'%' IDENTIFIED BY 'glancePass'; mysql> CREATE DATABASE neutron; mysql> GRANT ALL ON neutron.* TO 'neutronUser'@'%' IDENTIFIED BY 'neutronPass'; mysql> CREATE DATABASE nova; mysql> GRANT ALL ON nova.* TO 'novaUser'@'%' IDENTIFIED BY 'novaPass'; mysql> CREATE DATABASE cinder; mysql> GRANT ALL ON cinder.* TO 'cinderUser'@'%' IDENTIFIED BY 'cinderPass'; mysql> quit; Other Install other services: # apt-get install -y vlan bridge-utils Enable IP_Forwarding: # sed -i 's/#net.ipv4.ip_forward=1/net.ipv4.ip_forward=1/' /etc/sysctl.conf Also add the following two lines into/etc/sysctl.conf: net.ipv4.conf.all.rp_filter=0 net.ipv4.conf.default.rp_filter=0 To save you from reboot, perform the following # sysctl net.ipv4.ip_forward=1 # sysctl net.ipv4.conf.all.rp_filter=0 # sysctl net.ipv4.conf.default.rp_filter=0 # sysctl -p Keystone Keystone is an OpenStack project that provides Identity, Token, Catalog and Policy services for use specifically by projects in the OpenStack family. It implements OpenStack’s Identity API. Install Keystone packages: # apt-get install -y keystone Adapt the connection attribute in the /etc/keystone/keystone.conf to the new database: connection = mysql://keystoneUser:keystonePass@10.10.10.51/keystone Restart the identity service then synchronize the database: # service keystone restart # keystone-manage db_sync Fill up the keystone database using the below two scripts: keystone_basic.sh keystone_endpoints_basic.sh Run Scripts: $ chmod +x keystone_basic.sh $ chmod +x keystone_endpoints_basic.sh $ ./keystone_basic.sh $ ./keystone_endpoints_basic.sh Create a simple credentials file nano Crediantials.sh Paste the following: $ export OS_TENANT_NAME=admin $ export OS_USERNAME=admin $ export OS_PASSWORD=admin_pass $ export OS_AUTH_URL="http://192.168.100.51:5000/v2.0/" Load the above credentials: $ source Crediantials.sh To test Keystone, we use a simple CLI command: $ keystone user-list Glance The OpenStack Glance project provides services for discovering, registering, and retrieving virtual machine images. Glance has a RESTful API that allows querying of VM image metadata as well as retrieval of the actual image. VM images made available through Glance can be stored in a variety of locations from simple file systems to object-storage systems like the OpenStack Swift project. Glance, as with all OpenStack projects, is written with the following design guidelines in mind: Component based architecture: Quickly adds new behaviors Highly available: Scales to very serious workloads Fault tolerant: Isolated processes avoid cascading failures Recoverable: Failures should be easy to diagnose, debug, and rectify Open standards: Be a reference implementation for a community-driven api Install Glance # apt-get install -y glance Update /etc/glance/glance-api-paste.ini [filter:authtoken] paste.filter_factory = keystoneclient.middleware.auth_token:filter_factory delay_auth_decision = true auth_host = 10.10.10.51 auth_port = 35357 auth_protocol = http admin_tenant_name = service admin_user = glance admin_password = service_pass Update the /etc/glance/glance-registry-paste.ini [filter:authtoken] paste.filter_factory = keystoneclient.middleware.auth_token:filter_factory auth_host = 10.10.10.51 auth_port = 35357 auth_protocol = http admin_tenant_name = service admin_user = glance admin_password = service_pass Update the /etc/glance/glance-api.conf sql_connection = mysql://glanceUser:glancePass@10.10.10.51/glance [keystone_authtoken] auth_host = 10.10.10.51 auth_port = 35357 auth_protocol = http admin_tenant_name = service admin_user = glance admin_password = service_pass [paste_deploy] flavor = keystone Update the /etc/glance/glance-registry.conf sql_connection = mysql://glanceUser:glancePass@10.10.10.51/glance [keystone_authtoken] auth_host = 10.10.10.51 auth_port = 35357 auth_protocol = http admin_tenant_name = service admin_user = glance admin_password = service_pass [paste_deploy] flavor = keystone Restart the glance-api and glance-registry services: # service glance-api restart; service glance-registry restart Synchronize the Glance database: # glance-manage db_sync To test Glance, upload the “cirros cloud image” directly from the internet: $ glance image-create --name OS4Y_Cirros --is-public true --container-format bare --disk-format qcow2 --location https://launchpad.net/cirros/trunk/0.3.0/+download/cirros-0.3.0-x86_64-disk.img Check if the image is successfully uploaded: $ glance image-list Neutron Neutron is an OpenStack project to provide “network connectivity as a service" between interface devices (e.g., vNICs) managed by other OpenStack services (e.g., nova).
