Centos 6.4 openstack-grizzly Installation: Compute the node

This chapter is directly the official document, I have not made any changes. The previous two articles to be explained have already been explained. Because the server is nervous, so I put all on a server. Everything's fine.

Compute Node

Introduction

Common Services

OpenStack Compute (Compute Node Services)

Openstacknetworking (Compute Node)

Introduction

The Compute Nodewill provide:

Hypervisor (KVM)

Nova-compute

Quantum OVS Agent

Common Services

Operating System

Operating System

Install Fedora 18. Just like and the Cloud Controller, the exact steps are outside the scope of this document, but Options

Time ZONE:UTC

Hostname:c01

Packages:openssh-server

Once installation has finished, the server would reboot.

Use the Fedora repositories for Grizzly:

3.# Wgethttp://repos.fedorapeople.org/repos/openstack/openstack-grizzly/fedora-openstack-grizzly.repo

# yum install-yhttp://repos.fedorapeople.org/repos/openstack/openstack-grizzly/rdo-release-grizzly-1.noarch.rpm

Configure the network:

Note

This'll change later on guide when Open VSwitch is configured

Set up old Ethernet NIC device names:

# sed-i ' s/#GOTO = ' netdevicename_end '/goto= ' netdevicename_end '/g '/lib/udev/rules.d/71-biosdevname.rules

Edit/etc/sysconf/network-scripts/ifcfg-eth0:

# Internal Network

Device=eth0

Type=ethernet

Bootproto=static

ipaddr=10.10.10.11

netmask=255.255.255.0

gateway=10.10.10.9

dns1=8.8.8.8

Defroute=yes

Onboot=yes

Reboot.

Edit the/etc/hosts file and add cloud, network and C01 hostnames with correct IP.

127.0.0.1 localhost

10.10.10.10 Cloud

10.10.10.9 Network

10.10.10.11 C01

Install NTP:

• #yum install-y NTP

OpenStack Compute (Compute Node Services)

Just like and Thecloud Controller, the OpenStack Compute service is installed on the Computenode. However, this time the Nova-computeservice is installed. This is provides Thecompute Node the capability to host virtual machines.

Install the Nova Compute package:

# yum Install Openstack-nova-compute

Configure Nova:

Edit/etc/nova/api-paste.ini:

· [Filter:authtoken]

Auth_host = 10.10.10.10

admin_tenant_name = Service

Admin_user = Nova

Admin_password = password

Edit/etc/nova/nova.conf:

· [DEFAULT]

·

# General

Verbose=true

qpid_hostname=192.168.206.130

·

Auth_strategy=keystone

ec2_host=10.10.10.10

Ec2_url=http://10.10.10.10:8773/services/cloud
