OpenStack Deployment Installation (Icehouse version)-Control node (Controller)-Compute service (NOVA)

Nova is a compute service that can start a virtual machine instance. These services can be configured on a separate node or on the same node. Most services run on the controller node and run the virtual machine service on a dedicated compute node. This time, we deploy the compute to the control node.

4.1 Install Compute Controller services (Installation Compute service)

4.1.1 installation of compute required Packages

# yum Install Openstack-nova-api Openstack-nova-cert openstack-nova-conductor openstack-nova-console Openstack-nova-novncproxy Openstack-nova-scheduler python-novaclient

4.1.2 Creating a database for Nova

# mysql-u root-pmysql> CREATE DATABASE nova;mysql> GRANT all privileges on nova.* to ' nova ' @ ' localhost ' identified By ' Nova ';mysql> GRANT all privileges on nova.* to ' Nova ' @ ' percent ' identified by ' Nova ';

4.1.3 Modifying a Nova's configuration file to create a database connection

# openstack-config--set/etc/nova/nova.conf database connection Mysql://nova:[email Protected]/nova

4.1.4 modifies the Nova configuration file, using a specific message service qpid. After modifying the MY_IP,NVC service

# openstack-config--set/etc/nova/nova.conf DEFAULT rpc_backend qpid# openstack-config--set/etc/nova/nova.conf DEFAUL T qpid_hostname controller# openstack-config--set/etc/nova/nova.conf DEFAULT my_ip 10.0.0.11# openstack-config--set/e tc/nova/nova.conf default Vncserver_listen 10.0.0.11# openstack-config--set/etc/nova/nova.conf default Vncserver_ Proxyclient_address 10.0.0.1

4.1.5 Creating a database table for Nova

# su-s/bin/sh-c "Nova-manage db Sync" Nova

4.1.6 Create a Nova user and add it to the admin role

# keystone User-create--name=nova--pass=nova [email protected]# Keystone User-role-add--user=nova--tenant=service--r Ole=admin

4.1.7 Configuring the Nova service to allow authentication to run on the control node

# openstack-config--set/etc/nova/nova.conf DEFAULT auth_strategy keystone# openstack-config--set/etc/nova/nova.conf Keystone_authtoken Auth_uri http://controller:5000# openstack-config--set/etc/nova/nova.conf Keystone_authtoken Auth_host controller# openstack-config--set/etc/nova/nova.conf keystone_authtoken auth_protocol http# Openstack-config--set/etc/nova/nova.conf keystone_authtoken auth_port 35357# openstack-config--set/etc/nova/ nova.conf keystone_authtoken admin_user nova# openstack-config--set/etc/nova/nova.conf keystone_authtoken admin_ Tenant_name service# openstack-config--set/etc/nova/nova.conf Keystone_authtoken Admin_password Nova

4.1.8 Create a Nova service and create a endpoint

# Keystone Service-create--name=nova--type=compute--description= "OpenStack Compute" # Keystone Endpoint-create--ser   vice-id=$ (Keystone Service-list | awk '/COMPUTE/{print $} ')--publicurl=http://controller:8774/v2/%\ (tenant_id\) s --internalurl=http://controller:8774/v2/%\ (tenant_id\) s--adminurl=http://controller:8774/v2/%\ (tenant_id\) s

4.1.9 start the Nova service and add the Nova service to the boot auto-start

# service Openstack-nova-api start# service Openstack-nova-cert start# service Openstack-nova-consoleauth start# Service Openstack-nova-scheduler start# service openstack-nova-conductor start# service Openstack-nova-novncproxy start# Chkconfig openstack-nova-api on# chkconfig openstack-nova-cert on# chkconfig openstack-nova-consoleauth on# chkconfig Openstack-nova-scheduler on# chkconfig openstack-nova-conductor on# chkconfig openstack-nova-novncproxy on

4.1.10 See if the Nova service is installed properly

# Nova Image-list

Here, the Nova service is already installed. If the above authentication problem is true, execute the following source admin.sh
