openstack controller ha测试环境搭建记录（十一）——配置neutron（网络节点）

标签：

在网络节点配置内核参数：
vi /etc/sysctl.conf
net.ipv4.ip_forward=1
net.ipv4.conf.all.rp_filter=0
net.ipv4.conf.default.rp_filter=0

在网络节点使内核参数立即生效：
sysctl -p


在网络节点安装软件：
yum install -y openstack-neutron openstack-neutron-ml2 openstack-neutron-openvswitch


在网络节点修改配置文件：
openstack-config --set /etc/neutron/neutron.conf DEFAULT rpc_backend rabbit
openstack-config --set /etc/neutron/neutron.conf DEFAULT rabbit_password 123456
openstack-config --set /etc/neutron/neutron.conf DEFAULT rabbit_hosts controller1:5672,controller2:5672,controller3:5672

openstack-config --set /etc/neutron/metadata_agent.ini DEFAULT metadata_proxy_shared_secret METADATA_SECRET

在控制节点修改配置文件：
openstack-config --set /etc/nova/nova.conf neutronservice_metadata_proxy True
openstack-config --set /etc/nova/nova.conf neutronmetadata_proxy_shared_secret METADATA_SECRET

重启控制节点nova服务：
systemctl restart openstack-nova-api.service


在网络节点：
systemctl enable openvswitch.service
systemctl start openvswitch.service


ovs-vsctl add-br br-ex
ovs-vsctl add-port br-ex INTERFACE_NAME
ethtool -K INTERFACE_NAME gro off


ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
cp /usr/lib/systemd/system/neutron-openvswitch-agent.service \
  /usr/lib/systemd/system/neutron-openvswitch-agent.service.orig
sed -i ‘s,plugins/openvswitch/ovs_neutron_plugin.ini,plugin.ini,g‘ \
  /usr/lib/systemd/system/neutron-openvswitch-agent.service

systemctl enable neutron-openvswitch-agent.service neutron-l3-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service neutron-ovs-cleanup.service
systemctl start neutron-openvswitch-agent.service neutron-l3-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service


验证：
source admin-openrc.sh
