OpenStack Juno : Configure Neutron#3 ( Compute Node )
2015/01/09 |
|
Configure OpenStack Network Service (Neutron).
For this example, Install Neutron Server on Control Node which Keystone/Glance/Nova API are already installed,
and Install DHCP Agent, L3 Agent, L2 Agent, Metadata Agent on Network Node, and also Install L2 Agent on Compute Node on here.
( it's possible to install on a server as All-in-One, though, if you want )
Neutron needs a plugin software, it's possible to choose it from some softwares.
This example chooses ML2 plugin. ( it uses Open vSwitch under the backend )
|
+------------------+ | +------------------------+
| [ Control Node ] | | | [ Network Node ] |
| Keystone |10.0.0.30 | 10.0.0.50| DHCP Agent |
| Glance |------------+------------| L3 Agent |
| Nova API |eth0 | eth0| L2 Agent |
| Neutron Server | | | Metadata Agent |
+------------------+ | +------------------------+
eth0|10.0.0.51
+--------------------+
| [ Compute Node ] |
| Nova Compute |
| L2 Agent |
+--------------------+

Configure Compute Node on here.

|
| [1] | Change the kernel parameters for rp_filter. |
|
[root@node01 ~]# echo 'net.ipv4.conf.default.rp_filter=0' >> /etc/sysctl.conf [root@node01 ~]# echo 'net.ipv4.conf.all.rp_filter=0' >> /etc/sysctl.conf [root@node01 ~]# sysctl -p |
| [2] | Install some packages for Compute Node. |
|
[root@node01 ~]# yum --enablerepo=openstack-juno,epel -y install openstack-neutron openstack-neutron-ml2 openstack-neutron-openvswitch
|
| [3] | Configure as a Compute Node. |
