8. 安装neutron（网络节点）— OpenStack Queens 三节点部署

本操作在网络节点上完成

安装neutron软件包

使用OVS作为虚拟交换机

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配置文件

由于官方配置文件修改较为麻烦，这里直接创建一个新的配置文件

root@network:~# mv /etc/neutron/neutron.conf /etc/neutron/neutron.conf.org
root@network:~# vi /etc/neutron/neutron.conf

# 添加以下内容，保存退出

[DEFAULT]
core_plugin = ml2
service_plugins = router
auth_strategy = keystone
state_path = /var/lib/neutron
allow_overlapping_ips = True
# 消息队列连接设置
transport_url = rabbit://openstack:root@controller

[agent]
root_helper = sudo /usr/bin/neutron-rootwrap /etc/neutron/rootwrap.conf

# Keystone连接设置
[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

因为配置文件是新建的，这里把权限加回去

root@network:~# chmod 640 /etc/neutron/neutron.conf
root@network:~# chgrp neutron /etc/neutron/neutron.conf

修改三层代理配置

root@network:~# vi /etc/neutron/l3_agent.ini

# 第17行：去掉注释并添加

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：去掉注释并添加
interface_driver = neutron.agent.linux.interface.OVSInterfaceDriver

# 第28行：去掉注释
dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq
 
# 第37行：取消注释并修改
enable_isolated_metadata = True

修改元数据代理配置

root@network:~# vi /etc/neutron/metadata_agent.ini

# 第22行：去掉注释并添加控制节点IP
nova_metadata_host = 10.0.0.7
 
# 第34行：去掉注释并添加元数据代理共享密码
metadata_proxy_shared_secret = metadata_secret
 
# 第260行：去掉注释并添加控制节点IP
memcache_servers = 10.0.0.7:11211

修改二层插件配置

root@network:~# vi /etc/neutron/plugins/ml2/ml2_conf.ini

# 第129行：添加相应设置（tenant_network_types设置暂时留空，之后会设置）
[ml2]
type_drivers = flat,vlan,gre,vxlan
tenant_network_types =
mechanism_drivers = openvswitch,l2population
extension_drivers = port_security

# 第262行：去掉注释并添加firewall_driver
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver

# 最后一行：取消注释
enable_ipset = True

创建链接文件、重启服务

创建链接文件

root@network:~# ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini

重启服务

root@network:~# systemctl enable openvswitch-switch neutron-openvswitch-agent neutron-l3-agent neutron-dhcp-agent neutron-metadata-agent
Synchronizing state of openvswitch-switch.service with SysV init with /lib/systemd/systemd-sysv-install...

root@network:~# systemctl restart openvswitch-switch neutron-openvswitch-agent neutron-l3-agent neutron-dhcp-agent neutron-metadata-agent
