安裝neutron軟體包
使用OVS作為虛擬交換機
root@network:~# apt -y install neutron-plugin-ml2 neutron-l3-agent neutron-dhcp-agent neutron-metadata-agent python-neutronclient neutron-openvswitch-agent
修改neutron組態檔
由于官方組態檔修改較為麻煩，這里直接創建一個新的組態檔
root@network:~# mv /etc/neutron/neutron.conf /etc/neutron/neutron.conf.org
root@network:~# vi /etc/neutron/neutron.conf
# 添加以下內容，保存退出
[DEFAULT]
core_plugin = ml2
service_plugins = router
auth_strategy = keystone
state_path = /var/lib/neutron
allow_overlapping_ips = True
# 訊息佇列連接設定
transport_url = rabbit://openstack:root@controller
[agent]
root_helper = sudo /usr/bin/neutron-rootwrap /etc/neutron/rootwrap.conf
# Keystone連接設定
[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = root
[oslo_concurrency]
lock_path = $state_path/lock
因為組態檔是新建的，這里把權限加回去
root@network:~# chmod 640 /etc/neutron/neutron.conf
root@network:~# chgrp neutron /etc/neutron/neutron.conf
修改三層代理配置
root@network:~# vi /etc/neutron/l3_agent.ini
# 第17行：去掉注釋并添加
interface_driver = neutron.agent.linux.interface.OVSInterfaceDriver
修改DHCP代理配置
root@network:~# vi /etc/neutron/dhcp_agent.ini
# 第17行：去掉注釋并添加
interface_driver = neutron.agent.linux.interface.OVSInterfaceDriver
# 第28行：去掉注釋
dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq
# 第37行：取消注釋并修改
enable_isolated_metadata = https://www.cnblogs.com/zhaoyixin96/p/True
修改元資料代理配置
root@network:~# vi /etc/neutron/metadata_agent.ini
# 第22行：去掉注釋并添加控制節點IP
nova_metadata_host = 10.0.0.7
# 第34行：去掉注釋并添加元資料代理共享密碼
metadata_proxy_shared_secret = metadata_secret
# 第260行：去掉注釋并添加控制節點IP
memcache_servers = 10.0.0.7:11211
修改二層插件配置
root@network:~# vi /etc/neutron/plugins/ml2/ml2_conf.ini
# 第129行：添加相應設定（tenant_network_types設定暫時留空，之后會設定）
[ml2]
type_drivers = flat,vlan,gre,vxlan
tenant_network_types =
mechanism_drivers = openvswitch,l2population
extension_drivers = port_security
# 第262行：去掉注釋并添加firewall_driver
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
# 最后一行：取消注釋
enable_ipset = True
創建鏈接檔案、重啟服務
創建鏈接檔案
root@network:~# ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
