Ubuntu搭建Openstack平台（kilo）(五.neutron(二)网络节点与计算节点)

参考文档：http://www.aboutyun.com/thread-13116-1-1.html

网络节点

一.配置参数

• 环境配置

vim /etc/sysctl.conf

net.ipv4.ip_forward=1
net.ipv4.conf.all.rp_filter=0
net.ipv4.conf.default.rp_filter=0

• 使配置生效

sysctl -p

二.安装neutron组件

1.安装

apt-get install neutron-plugin-ml2 neutron-plugin-openvswitch-agent neutron-l3-agent neutron-dhcp-agent neutron-metadata-agent -y

2.修改配置

vim /etc/neutron/neutron.conf

[DEFAULT]
verbose = True
rpc_backend = rabbit
#配置认证访问
auth_strategy = keystone

#启用 Modular Layer 2 (ML2) plug-in,路由服务, 和 overlapping IP addresses:
core_plugin = ml2
service_plugins = router
allow_overlapping_ips = True

#在[database]模块注释掉connection，因为网络节点不需要连接数据库

[oslo_messaging_rabbit]
#配置RabbitMQ 消息队列服务
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = RABBIT_PASS(密码为创建的消息中间件密码，我的为123)

[keystone_authtoken]
#配置认证访问
auth_uri = http://controller:5000
auth_url = http://controller:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
project_name = service
username = neutron
password = NEUTRON_PASS(我的密码为neutron)

3.修改Modular Layer 2 (ML2) plug-in

vim /etc/neutron/plugins/ml2/ml2_conf.ini

[ml2]
#启用flat,VLAN,GRE和VXLAN网络类型驱动,GRE租户网络,和OVS机制驱动:
