openstack私有云布署实践【12.2 网络Neutron-controller节点配置（办公网环境）】
网络这一块推荐使用的是 Neutron--LinuxBirdge的Ha高可用，此高可用方案对Public作用不是很大，Public只用到DHCP，而Private则会用到L3 Agent，则此方案是有用的，但要关掉和牺牲一个L3 population的特性--抑制ARP报文广播。原因在下文的配置文件有说明，并因我们布的是私有云，不像公有云的多租户private网络数量之大，这个特性牺牲在中小私有云是可接受的。
一、首先登录controller1创建neutron数据库，并赋于远程和本地访问的权限。
mysql -u root -p
CREATE DATABASE neutron;
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' IDENTIFIED BY 'venic8888';
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' IDENTIFIED BY 'venic8888';
flush PRIVILEGES;
二、身份认证调用
其中一台controller创建身份认证调用
source admin-openrc.sh
openstack user create --domain default --password-prompt neutron
User Password:
Repeat User Password:

三、下载安装neutron组件
1公有网络配置+私有网络配置
2台controller配置
# yum install openstack-neutron openstack-neutron-ml2 openstack-neutron-linuxbridge python-neutronclient ebtables ipset -y
修改新增内核参数：
vi /etc/sysctl.conf
net.ipv4.ip_forward=1
net.ipv4.conf.default.rp_filter=0
net.ipv4.conf.all.rp_filter=0
sysctl -p
配置neutron.conf服务
在controller1
vi /etc/neutron/neutron.conf
[DEFAULT]
core_plugin = ml2
service_plugins = router
allow_overlapping_ips = True
rpc_backend = rabbit
auth_strategy = keystone
bind_host = 10.40.42.1
bind_port = 9696
l3_ha = True
max_l3_agents_per_router = 3
min_l3_agents_per_router = 2
allow_automatic_l3agent_failover = True
dhcp_agents_per_network = 2
notify_nova_on_port_status_changes = True
notify_nova_on_port_data_changes = True
nova_url = http://controller:8774/v2
verbose = True
[database]
connection = mysql://neutron:venic8888@controller/neutron
[keystone_authtoken]
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
[nova]
auth_url = http://controller:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
region_name = RegionOne
project_name = service
username = nova

[oslo_messaging_rabbit]
rabbit_host=controller
rabbit_userid = openstack
rabbit_password = openstack
rabbit_retry_interval=1
rabbit_retry_backoff=2
rabbit_max_retries=0
rabbit_durable_queues=true
rabbit_ha_queues=true
[oslo_concurrency]
lock_path = /var/lib/neutron/tmp
[quotas]
quota_port = 10000
在kxcontroller2
vi /etc/neutron/neutron.conf
[DEFAULT]
core_plugin = ml2
service_plugins = router
allow_overlapping_ips = True
rpc_backend = rabbit
auth_strategy = keystone
bind_host = 10.40.42.2
bind_port = 9696
l3_ha = True
max_l3_agents_per_router = 3
min_l3_agents_per_router = 2
allow_automatic_l3agent_failover = True
dhcp_agents_per_network = 2
notify_nova_on_port_status_changes = True
notify_nova_on_port_data_changes = True
nova_url = http://controller:8774/v2
verbose = True
[database]
connection = mysql://neutron:venic8888@controller/neutron
[keystone_authtoken]
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
[nova]
auth_url = http://controller:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
region_name = RegionOne
project_name = service
username = nova
password = nova
[oslo_messaging_rabbit]
rabbit_host=controller
rabbit_userid = openstack
rabbit_password = openstack
rabbit_retry_interval=1
rabbit_retry_backoff=2
rabbit_max_retries=0
rabbit_durable_queues=true
rabbit_ha_queues=true
[oslo_concurrency]
lock_path = /var/lib/neutron/tmp
[quotas]
quota_port = 10000
2台controller上配置一样
vi /etc/neutron/plugins/ml2/ml2_conf.ini
[ml2]
type_drivers = flat,vlan,vxlan
tenant_network_types = vxlan
extension_drivers = port_security
mechanism_drivers = linuxbridge
[ml2_type_flat]
flat_networks = public
[ml2_type_vxlan]
vni_ranges = 1:10000
vxlan_group = 239.2.1.1
[securitygroup]
enable_ipset = True
配置ML2服务配置，跟单服务的自由版本的配法不同，这次使用的l3 HA，不用使用l2_population机制，因有BGU还没修复（切换时，虽然publick的VRRP切换成功。private网段的网关不会触发更新，VM虚拟是PING不通private的网关）
在controller1上
vi /etc/neutron/plugins/ml2/linuxbridge_agent.ini
[linux_bridge]
physical_interface_mappings = public:bond0
[vxlan]
enable_vxlan = True
local_ip = 10.40.42.1
l2_population = False
[agent]
prevent_arp_spoofing = True
[securitygroup]
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
在controller2上
vi /etc/neutron/plugins/ml2/linuxbridge_agent.ini
[linux_bridge]
physical_interface_mappings = public:bond0
[vxlan]
enable_vxlan = True
local_ip = 10.40.42.2
l2_population = False
[agent]
prevent_arp_spoofing = True
[securitygroup]
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
配置L3-agent服务
2台kxcontroller配置一样
vi /etc/neutron/l3_agent.ini
[DEFAULT]
interface_driver = neutron.agent.linux.interface.BridgeInterfaceDriver
external_network_bridge =
verbose = True
router_delete_namespaces = True
agent_mode = legacy
配置DHCP服务
2台controller配置一样
vi /etc/neutron/dhcp_agent.ini
[DEFAULT]
interface_driver = neutron.agent.linux.interface.BridgeInterfaceDriver
dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq
enable_isolated_metadata = True
verbose = True
use_namespaces = True
dhcp_delete_namespaces = True
dnsmasq_config_file = /etc/neutron/dnsmasq-neutron.conf
额外配置DHCP MTU配置
2台controller配置一样
vi /etc/neutron/dnsmasq-neutron.conf
dhcp-option-force=26,1450
配置metadata agent
2台controller配置一样
vi /etc/neutron/metadata_agent.ini
[DEFAULT]
auth_uri = http://controller:5000
auth_url = http://controller:35357
auth_region = RegionOne
auth_plugin = password
project_domain_id = default
user_domain_id = default
project_name = service
username = neutron
password = neutron
nova_metadata_ip = controller
metadata_proxy_shared_secret = venicchina
新加配置nova与neutron关联-----在11节中我就有提到的那个紫色的配置，这里再提一次
vi /etc/nova/nova.conf
[neutron]
url = http://controller:9696
auth_url = http://controller:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
region_name = RegionOne
project_name = service
username = neutron
password = neutron
service_metadata_proxy = True
metadata_proxy_shared_secret = venicchina
验证：
1、controller的软链接
ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
2、其中一台controller同步数据
# su -s /bin/sh -c "neutron-db-manage --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade head" neutron
3、两台controller重启nova api
# systemctl restart openstack-nova-api.service
4、两台controller开启网络服务，加入开机自启
# systemctl enable neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service neutron-l3-agent.service
# systemctl start neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service neutron-l3-agent.service
