OpenStack Grizzly - Configure Quantum#22013/09/12

Configure OpenStack Network Service (Quantum).

This example shows to configure Quantum on the environment below.

                                |
+------------------+            |            +------------------------+
| [ Control Node ] |10.0.0.30   |   10.0.0.31|    [ Network Node ]    |
|     Keystone     |------------+------------|        DHCP Agent      |
|  Quantum Server  |            |            |        L3 Agent        |
+------------------+            |            |        L2 Agent        |
                                |            +------------------------+
                                |

                      +--------------------+
                      |  [ Compute Node ]  |

	Configure Network Node on here. By the way, it's necessarry to select plugin-software to configure Quantum and this example selects linuxbridge plugin.
[1]	Enable IP forwarding first.

[root@network ~]#

sed -i -e "s/net.ipv4.ip_forward = 0/net.ipv4.ip_forward = 1/g" /etc/sysctl.conf

[root@network ~]#

sysctl -p

[2]	Update system from EPEL OpenStack to use Network Namespace and Install Quantum packages.

# install from EPEL OpenStack, EPEL

[root@network ~]#

yum --enablerepo=epel-openstack-grizzly,epel -y update

[root@network ~]#

yum --enablerepo=epel-openstack-grizzly,epel -y install openstack-quantum openstack-quantum-linuxbridge python-keystoneclient

[root@network ~]#

reboot

[3]	Load environment variables.

[root@network ~]#

vi ~/keystonerc_quantum

export OS_USERNAME=quantum
export OS_PASSWORD=servicepassword
export OS_TENANT_NAME=service
export OS_AUTH_URL=http://10.0.0.30:35357/v2.0/
export PS1='[\u@\h \W(quantum)]\$ '

[root@network ~]#

chmod 600 ~/keystonerc_quantum

[root@network ~]#

source ~/keystonerc_quantum

[root@network ~(quantum)]#

echo "source ~/keystonerc_quantum " >> ~/.bash_profile

[4]	Configure DHCP, L3, L2 Agent

[root@network ~(quantum)]#

quantum-dhcp-setup --plugin linuxbridge

Quantum plugin: linuxbridge
Please enter the Quantum hostname:

10.0.0.30

# specify QPID's hostname or IP address

Configuration updates complete!
[root@network ~(quantum)]#

quantum-l3-setup --plugin linuxbridge

Quantum plugin: linuxbridge
Please enter the Quantum hostname:

10.0.0.30

# specify QPID's hostname or IP address

Configuration updates complete!
[root@network ~(quantum)]#

quantum-node-setup --plugin linuxbridge

Quantum plugin: linuxbridge
Please enter the Quantum hostname:

10.0.0.30

# specify QPID's hostname or IP address

Would you like to update the nova configuration files? (y/n):

Complete!

[root@network ~(quantum)]#
