一步一步跟着官方文档安装部署Openstack(icehouse)五
继OpenStack安装部署四六、添加NETWORK（网络）服务
配置控制节点
# openstack-config --set /etc/nova/nova.conf DEFAULT \
network_api_class nova.network.api.API
# openstack-config --set /etc/nova/nova.conf DEFAULT \
security_group_api nova 重启 服务
# service openstack-nova-api restart
# service openstack-nova-scheduler restart
# service openstack-nova-conductor restart
配置计算节点
# yum install openstack-nova-network openstack-nova-api
修改配置文件，INTERFACE_NAME修改为eth1
# openstack-config --set /etc/nova/nova.conf DEFAULT \
network_api_class nova.network.api.API
# openstack-config --set /etc/nova/nova.conf DEFAULT \
security_group_api nova
# openstack-config --set /etc/nova/nova.conf DEFAULT \
network_manager nova.network.manager.FlatDHCPManager
# openstack-config --set /etc/nova/nova.conf DEFAULT \
firewall_driver nova.virt.libvirt.firewall.IptablesFirewallDriver
# openstack-config --set /etc/nova/nova.conf DEFAULT \
network_size 254
# openstack-config --set /etc/nova/nova.conf DEFAULT \
allow_same_net_traffic False
# openstack-config --set /etc/nova/nova.conf DEFAULT \
multi_host True
# openstack-config --set /etc/nova/nova.conf DEFAULT \
send_arp_for_ha True
# openstack-config --set /etc/nova/nova.conf DEFAULT \
share_dhcp_address True
# openstack-config --set /etc/nova/nova.conf DEFAULT \
force_dhcp_release True
# openstack-config --set /etc/nova/nova.conf DEFAULT \
flat_network_bridge br100
# openstack-config --set /etc/nova/nova.conf DEFAULT \
flat_interface INTERFACE_NAME
# openstack-config --set /etc/nova/nova.conf DEFAULT \
public_interface INTERFACE_NAME
配置文件中 flat网络桥接到br100上，所以我们需要将br100桥接到eth1上
安装桥接工具
yum install bridge-utils 添加桥接接口
brctl addbr br100 eth1 查看桥接状态
# brctl show
bridge name bridge id STP enabled interfaces
br100 8000.000c29da52c1 no eth1
virbr0 8000.525400b8f71e yes virbr0-nic 设置网卡eth1混杂模式
# ip link set eth1 promisc on 查看eth1模式
ip link show eth1 启动相关服务并加入启动列表
# service openstack-nova-network start
# service openstack-nova-metadata-api start
# chkconfig openstack-nova-network on
# chkconfig openstack-nova-metadata-api on
创建初始网络（控制节点）
nova network-create demo-net --bridge br100 --multi-host T \
--fixed-range-v4 10.0.0.32/29 查看网络
# nova net-list
+--------------------------------------+----------+--------------+
| ID | Label | CIDR |
+--------------------------------------+----------+--------------+
| 5ec9d9f9-87cd-4089-8b84-2ddc24e0171b | demo-net | 10.0.0.32/29 |
+--------------------------------------+----------+--------------+ 至此网络服务添加完成。加油！
