OpenStack Kilo : Configure Neutron (Compute Node)
2015/06/13
 
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 )

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.
# install from RDO, EPEL

[root@node01 ~]#
yum --enablerepo=openstack-kilo,epel -y install openstack-neutron openstack-neutron-ml2 openstack-neutron-openvswitch
[3] Configure as a Compute Node.
