第五章-网络服务之控制节点部署

第一步创建数据库

第二步创建`neutron``用户

创建``neutron``服务实体:

[root@openstack-1 ~]# openstack service create --name neutron \
>   --description "OpenStack Networking" network
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | OpenStack Networking             |
| enabled     | True                             |
| id          | e898872450d44c33b9ac063b616a234d |
| name        | neutron                          |
| type        | network                          |
+-------------+----------------------------------+

创建网络服务API端点:

[root@openstack-1 ~]# openstack endpoint create --region RegionOne \
>   network public http://192.168.10.131:9696

+--------------+----------------------------------+

网络选项1:公共网络

安装软件:

[root@openstack-1 ~]# yum install openstack-neutron openstack-neutron-ml2 \
>   openstack-neutron-linuxbridge ebtables

配置网络服务

编辑``/etc/neutron/neutron.conf`` 文件并完成如下操作:

 

  • 在 [database] 部分,配置数据库访问:
  • [database]
    connection = mysql+pymysql://neutron:neutron@192.168.10.172/neutron

 

  • 在``[DEFAULT]``部分,启用ML2插件并禁用其他插件:
[DEFAULT]
core_plugin = ml2
service_plugins =
  • 在 “[DEFAULT]”部分,配置 “RabbitMQ” 消息队列的连接:
[DEFAULT]
transport_url = rabbit://openstack:openstack@192.168.10.131
  • 在 “[DEFAULT]” 和 “[keystone_authtoken]” 部分,配置认证服务访问:
[DEFAULT]
auth_strategy = keystone
[keystone_authtoken]

auth_uri = http://192.168.10.131:5000
auth_url = http://192.168.10.131:35357
memcached_servers = 192.168.10.131:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = neutron

 
  • 在``[DEFAULT]``和``[nova]``部分,配置网络服务来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://192.168.10.131:5000
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = nova
password = nova
  • 在 [oslo_concurrency] 部分,配置锁路径:
[oslo_concurrency]
lock_path = /var/lib/neutron/tmp

配置 Modular Layer 2 (ML2) 插件

ML2插件使用Linuxbridge机制来为实例创建layer-2虚拟网络基础设施

  • 编辑``/etc/neutron/plugins/ml2/ml2_conf.ini``文件并完成以下操作:

    • 在``[ml2]``部分,启用flat和VLAN网络:

    • [ml2]
      type_drivers = flat,vlan
    • 在``[ml2]``部分,禁用私有网络
    • [ml2]
      tenant_network_types =
    • 在``[ml2]``部分,启用Linuxbridge机制
    • [ml2]
      mechanism_drivers = linuxbridge
    • 在``[ml2]`` 部分,启用端口安全扩展驱动:
    • [ml2]
      extension_drivers = port_security
    • 在``[ml2_type_flat]``部分,配置公共虚拟网络为flat网络
    • [ml2_type_flat]
      flat_networks = provider
    • 在 ``[securitygroup]``部分,启用 ipset 增加安全组规则的高效性:

    • [securitygroup]
      enable_ipset = true

       

配置Linuxbridge代理

Linuxbridge代理为实例建立layer-2虚拟网络并且处理安全组规则。

  • 编辑``/etc/neutron/plugins/ml2/linuxbridge_agent.ini``文件并且完成以下操作:

    • 在``[linux_bridge]``部分,将公共虚拟网络和公共物理网络接口对应起来:

    • [linux_bridge]
      physical_interface_mappings = public:em1
    • 在``[vxlan]``部分,禁止VXLAN覆盖网络:
    • [vxlan]
      enable_vxlan = False
    • 在 ``[securitygroup]``部分,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DHCP代理

编辑``/etc/neutron/dhcp_agent.ini``文件并完成下面的操作:

  • 在``[DEFAULT]``部分,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 = neutron.agent.linux.interface.BridgeInterfaceDriver
    dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq
    enable_isolated_metadata = True

     

 

配置元数据代理

编辑``/etc/neutron/metadata_agent.ini``文件并完成以下操作:

  • 在``[DEFAULT]`` 部分,配置元数据主机以及共享密码:

  • [DEFAULT]
    nova_metadata_host = 192.168.10.131
    metadata_proxy_shared_secret = yan

 

为计算节点配置网络服务

  • 编辑``/etc/nova/nova.conf``文件并完成以下操作:

    • 在``[neutron]``部分,配置访问参数,启用元数据代理并设置密码:

    • [neutron]
      url = http://192.168.10.131:9696
      auth_url = http://192.168.10.131:5000
      auth_type = password
      project_domain_name = default
      user_domain_name = default
      region_name = RegionOne
      project_name = service
      username = neutron
      password = neutron
      service_metadata_proxy = true
      metadata_proxy_shared_secret = yan

完成安装

  • 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
  • 重启计算API 服务:
  • systemctl restart openstack-nova-api.service
  • 当系统启动时,启动 Networking 服务并配置它启动。

    对于两种网络选项:

  • systemctl enable neutron-server.service \
      neutron-linuxbridge-agent.service neutron-dhcp-agent.service \
      neutron-metadata-agent.service
    systemctl start neutron-server.service \
      neutron-linuxbridge-agent.service neutron-dhcp-agent.service \
      neutron-metadata-agent.service

     

验证

[root@openstack-1 ~]# neutron agent-list
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.
