Openstack (Kilo) installation series Nova (eight)

COMPUTE nodes

To install and configure the Compute hypervisor components

1.Install the Packages:

Yum Install Openstack-nova-compute sysfsutils

2.Edit the file and complete the /etc/nova/nova.conf following actions:

[DEFAULT] [oslo_messaging_rabbit] in the and sections, configure RabbitMQ message queue access:

= = = = Rabbit_pass

Replace RABBIT_PASS with the password your chose for the account in openstack RabbitMQ.

[DEFAULT] [keystone_authtoken] in the and sections, configure Identity service access:

== http://controller:5000auth_url = http://controller:35357auth_ Plugin == = = == Nova_pass

Replace NOVA_PASS with the password your chose for the nova user in the Identity service.

Note: Comment out or remove any other options in the section [keystone_authtoken] .

[DEFAULT]in the section, configure the my_ip option:

= Management_interface_ip_address

Replace MANAGEMENT_INTERFACE_IP_ADDRESS with the IP address of the management network interface on your compute node

[DEFAULT]in the section, enable and configure Remote console access:

=0.0. 0.0  == http://controller:6080/vnc_auto.html

The server component listens on all IP addresses and the proxy component only listens on the management interface IP Addre SS of the Compute node. The base URL indicates the location where can I use a Web browser to access remote consoles of instances on this compute Node.

[glance]in the sections, configure the location of the Image service:

= Controller

[oslo_concurrency]in the section, configure the lock path:

=/var/lib/nova/tmp

(Optional) To assist with troubleshooting, enable verbose logging in the section [DEFAULT] :

= True

To finalize Installation

1.Determine Whether your compute node supports hardware acceleration for virtual machines:

Egrep ' (VMX|SVM) ' /proc/cpuinfo

If This command returns a value of one or greater, your compute node supports hardware acceleration which Typ Ically requires no additional configuration.

If This command returns a value of zero, your compute node does not the support hardware acceleration and you mus T configure to use libvirt QEMU instead of KVM.

Edit the section in the [libvirt] /etc/nova/nova.conf file as follows:

= Qemu

2.Start the Compute service including its dependencies and configure them to Start automatically when the system boots:

Systemctl Enable Libvirtd.service openstack-nova-compute.servicesystemctl start Libvirtd.service openstack- Nova-compute.service
