這一章節直接就是官方文檔了，我沒做什麼更改。要說明的前面的兩篇已經說明了。因為服務器緊張，所以我是把所有裝在一台服務器上了。一切正常。
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 with the Cloud Controller, the exact steps are outside the scope of this document, but please note the following options:
Time zone: UTC
Hostname: c01
Packages: OpenSSH-Server
Once installation has finished, the server will 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 will change later on in the 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 with theCloud Controller, the OpenStack Compute service is installed on the ComputeNode. However, this time the nova-computeservice is installed. This 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
·
·# Networking
·libvirt_use_virtio_for_bridges=True
·network_api_class=nova.network.quantumv2.api.API
·quantum_url=http://10.10.10.10:9696
·quantum_auth_strategy=keystone

·quantum_admin_username=quantum
·quantum_admin_password=password
·quantum_admin_auth_url=http://10.10.10.10:35357/v2.0

vncserver_listen=0.0.0.0
Restart Nova services:
·# service openstack-nova-compute restart
# chkconfig openstack-nova-compute on
OpenStack Networking (Compute Node)
Open vSwitch
Quantum
Open vSwitch
Install the packages:
# yum install -y openvswitch-switch
Start Open vSwitch service
3.# service openvswitch-switch start
# chkconfig openvswitch-switch on
Create an internal bridge. Just as described in the Introduction to this guide, the Compute Node does not provide an external bridge. This enforces all instances' network traffic to go through the Network Controller. This is known as a "single-node" networking setup.
# ovs-vsctl add-br br-int
Quantum
Install the packages:
# yum install -yopenstack-quantum-openvswitch
Edit /etc/quantum/quantum.conf:
3.verbose = True
rpc_backend=quantum.openstack.common.rpc.impl_qpid
Edit /etc/quantum/plugins/openvswitch/ovs_quantum_plugin.ini:
5.[DATABASE]
6.sql_connection =mysql://quantum:[email protected]/quantum
7.[OVS]
8.tenant_network_type = gre
9.tunnel_id_ranges = 1:1000
10.local_ip = 10.10.10.11
11.enable_tunneling = True
12.[SECURITYGROUP]
13.firewall_driver =quantum.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
# ln -s/etc/quantum/plugins/openvswitch/ovs_quantum_plugin.ini /etc/quantum/plugin.ini
Start the Agent:
15.# service quantum-openvswitch-agentrestart
# chkconfig quantum-openvswitch-agent on
Ensure the cleanup utility is started on future boots:
# chkconfig quantum-ovs-cleanup on

Note
Check the /var/log/quantum/openvswitch-agent.log file for errors that would prevent the Networking service from successfully starting.
