OpenStack Icehouse : Configure Neutron#3 (Compute Node)2014/05/23 |
|
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 ] |

| Glance |------------+------------| L3 Agent |
| Nova API |eth0 | eth0| L2 Agent |
| Neutron Server | | | Metadata Agent |

| [ Compute Node ] |
| Nova Compute |
| L2 Agent |

root@node01:~# echo 'net.ipv4.conf.all.rp_filter=0' >> /etc/sysctl.conf root@node01:~# echo 'net.ipv4.conf.default.rp_filter=0' >> /etc/sysctl.conf root@node01:~# sysctl -p net.ipv4.conf.all.rp_filter = 0 net.ipv4.conf.default.rp_filter = 0 |
| [2] | Install some packages for Compute Node. |
