7.2.3 安装配置Neutron
Neutron 有两种网络选项:
- 公共网络:简单,但是只支持实例连接到公有网络(外部网络);没有私有网络(个人网络),路由器以及浮动IP地址;只有
admin
或者其他特权用户才可以管理公有网络; - 私有网络:在
公共网络
的基础上多了layer-3服务,支持实例连接到私有网络。demo
或者其他没有特权的用户可以管理自己的私有网络,包含连接公网和私网的路由器;另外,浮动IP地址可以让实例使用私有网络连接到外部网络;
这里使用 共有网络
;
私有网络配置失败,起来后DashBoard各种报错;先弄公有的跑通再说;
# 安装 Neutron
yum install openstack-neutron openstack-neutron-ml2 openstack-neutron-linuxbridge ebtables

[DEFAULT]
auth_strategy = keystone
[keystone_authtoken]
www_authenticate_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 = neutron
配置网络服务通知计算节点的网络拓扑变化
[DEFAULT]
notify_nova_on_port_status_changes = true
notify_nova_on_port_data_changes = true
[nova]
auth_url = http://controller:5000
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = nova
password = nova
配置锁路径
[oslo_concurrency]
lock_path = /var/lib/neutron/tmp
7.2.4 配置 Modular Layer 2 (ML2) 插件
vim /etc/neutron/plugins/ml2/ml2_conf.ini
启用flat,VLAN
配置完ML2插件后,移除type_drivers项,否则会导致数据库不一致
[ml2]
type_drivers = flat,vlan
禁用私有网络
[ml2]
tenant_network_types =
启用Linuxbridge
[ml2]
mechanism_drivers = linuxbridge
启用端口安全扩展驱动
[ml2]
extension_drivers = port_security
配置公共虚拟网络为flat网络
[ml2_type_flat]
flat_networks = provider
启用 ipset 增加安全组规则的高效性
[securitygroup]
enable_ipset = true
7.2.5 配置Linuxbridge代理
vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini
将公共虚拟网络和公共物理网络接口对应起来
# 只有一块网卡,直接用就好;
[linux_bridge]
physical_interface_mappings = provider:ens33
禁用VXLAN覆盖网络
[vxlan]
enable_vxlan = false
启用安全组并配置 Linuxbridge iptables firewall driver
[securitygroup]
enable_security_group = true
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
配置网络参数
# 加载br_netfilter模块
depmod
modprobe br_netfilter
lsmod | grep br_netfilter
br_netfilter 22256 0
bridge 151336 1 br_netfilter
sysctl -w net.bridge.bridge-nf-call-iptables=1
sysctl -w net.bridge.bridge-nf-call-ip6tables=1
7.2.6 配置DHCP代理
vim /etc/neutron/dhcp_agent.ini
配置Linuxbridge驱动接口,DHCP驱动并启用隔离元数据,这样在公共网络上的实例就可以通过网络来访问元数据
[DEFAULT]
interface_driver = linuxbridge
dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq
enable_isolated_metadata = true
7.2.7 配置元数据代理
vim /etc/neutron/metadata_agent.ini
配置元数据主机以及共享密码
# 共享密码使用默认的就行,和nova里的配置保持一致就好;
[DEFAULT]
nova_metadata_host = controller

user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = neutron
service_metadata_proxy = true
metadata_proxy_shared_secret = METADATA_SECRET
7.2.10 启动服务
网络服务初始化脚本需要一个超链接
/etc/neutron/plugin.ini
指向ML2插件配置文件/etc/neutron/plugins/ml2/ml2_conf.ini
。如果超链接不存在,使用下面的命令创建它
ln -sv /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
同步数据库
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
重启nova服务
systemctl restart openstack-nova-api.service
启动服务
systemctl start neutron-server neutron-linuxbridge-agent neutron-dhcp-agent neutron-metadata-agent
systemctl enable neutron-server neutron-linuxbridge-agent neutron-dhcp-agent neutron-metadata-agent
