CentOS7安装OpenStack（Queens版）——（五）neutron网络服务

neutron网络服务

控制节点

  1. 创建neutron数据库，自定义用户密码设置为neutron/neutron
mysql -uroot -proot
MariaDB [(none)]> CREATE DATABASE neutron;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' IDENTIFIED BY 'neutron';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' IDENTIFIED BY 'neutron';
MariaDB [(none)]> FLUSH PRIVILEGES;
  1. 加载admin临时环境变量
source keystonerc_admin
  1. 在keystone上创建neutron用户，密码自定义为neutron
[root@controller-01 ~]# openstack user create --domain default --password-prompt neutron
User Password:
Repeat User Password:
+---------------------+----------------------------------+
| Field               | Value                            |
+---------------------+----------------------------------+
| domain_id           | default                          |
| enabled             | True                             |
| id                  | 6dba19fbf1e44fc5b38d81315ecd141e |
| name                | neutron                          |
| options             | {}                               |
| password_expires_at | None                             |
+---------------------+----------------------------------+
  1. 给neutron用户添加admin角色权限，执行结果无输出
openstack role add --project service --user neutron admin
  1. 创建neutron服务实体
[root@controller-01 ~]# openstack service create --name neutron --description "OpenStack Networking" network
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+

| type        | network                          |
+-------------+----------------------------------+
  1. 创建网络服务API端点（endpoint）

配置网络选项

您可以使用选项1和2表示的两种体系结构之一来部署网络服务。

  • 选项1、部署了最简单的架构，它只支持将实例附加到提供商（外部）网络。没有自助服务（专用）网络、路由器或浮动IP地址。只有admin特权用户或其他特权用户可以管理提供商网络。

  • 选项2、增加了选项1的第3层服务支持将实例附加到自助服务网络。该demo用户或其他非特权用户可以管理自助服务网络，包括在自助服务网络和提供商网络之间提供连接的路由器。此外，浮动IP地址使用来自外部网络（例如 Internet）的自助服务网络提供与实例的连接。

自助服务网络通常使用覆盖网络。诸如 VXLAN 之类的覆盖网络协议包括额外的标头，这些标头会增加开销并减少可用于有效负载或用户数据的空间。在不了解虚拟网络基础结构的情况下，实例会尝试使用 1500 字节的默认以太网最大传输单元 (MTU) 发送数据包。网络服务通过 DHCP 自动为实例提供正确的 MTU 值。但是，某些云映像不使用 DHCP 或忽略 DHCP MTU 选项，需要使用元数据或脚本进行配置。

根据自己需求，这里我选择的选项2自助服务网络。

这里开始网络组件可以选择linuxbridge或者openvswitch，根据需要选择其中一种

安装组件(linuxbridge)

yum install openstack-neutron openstack-neutron-ml2 openstack-neutron-linuxbridge ebtables

配置服务组件

  • 编辑/etc/neutron/neutron.conf文件，修改如下区域参数，根据实际帐号密码信息修改
[database]
connection = mysql+pymysql://neutron:neutron@controller-01/neutron

[DEFAULT]
core_plugin = ml2
service_plugins = router
allow_overlapping_ips = true
transport_url = rabbit://openstack:openstack@controller-01
auth_strategy = keystone
notify_nova_on_port_status_changes = true
notify_nova_on_port_data_changes = true

[keystone_authtoken]
auth_uri = http://controller-01:5000
auth_url = http://controller-01:35357
memcached_servers = controller-01:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = neutron

[nova]
auth_url = http://controller-01:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = nova
password = nova

[oslo_concurrency]
lock_path = /var/lib/neutron/tmp
  • 检查配置的参数
egrep -v "^$|^#" /etc/neutron/neutron.conf

配置Modular Layer 2 (ML2)插件

  • 编辑/etc/neutron/plugins/ml2/ml2_conf.ini文件，修改如下参数
    • 在[ml2]区域，启用flat,VLAN,VXLAN网络

type_drivers = flat,vlan,vxlan
  • 在[ml2]区域，启用VXLAN自助服务网络
[ml2]
tenant_network_types = vxlan
  • 在[ml2]区域，启用Linux桥接和layer-2层填充机制
[ml2]
mechanism_drivers = linuxbridge,l2population

配置 ML2 插件后，删除 type_drivers 选项中的值会导致数据库不一致。
Linux桥接代理仅支持VXLAN网络

  • 在[ml2]区域，启用端口安全扩容驱动
[ml2]
extension_drivers = port_security

flat_networks = provider
  • 在[ml2_type_vxlan]区域，配置自助服务网络VXLAN网络认证范围
[ml2_type_vxlan]
vni_ranges = 1:1000
  • 在[securitygroup]区域，启用ipset以提高安全组规则的效率
[securitygroup]
enable_ipset = true
  • 检查配置的参数
egrep -v "^$|^#" /etc/neutron/plugins/ml2/ml2_conf.ini

配置Linux桥接代理

  • 编辑/etc/neutron/plugins/ml2/linuxbridge_agent.ini文件，配置如下参数
[linux_bridge]
physical_interface_mappings = provider:enp0s8     # 将提供者虚拟网络映射到提供者物理网络接口主机网卡二(enp0s8) 

[vxlan]
enable_vxlan = true
local_ip = 10.0.0.10    # 填写主机网卡二(enpp0s8) 上绑定的IP
l2_population = true

[securitygroup]
enable_security_group = true
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
  • 检查系统是否支持桥接模式防火墙，在启动neutron-linuxbridge-agent.service的时候会自动设置为1，结果显示1为开启
sysctl net.bridge.bridge-nf-call-iptables
sysctl net.bridge.bridge-nf-call-ip6tables

执行报错提示
sysctl: cannot stat /proc/sys/net/bridge/bridge-nf-call-iptables: No such file or directory
sysctl: cannot stat /proc/sys/net/bridge/bridge-nf-call-ip6tables: No such file or directory

  • 尝试启用br_netfilter模块，再次执行上面命令
modprobe br_netfilter
  • 检查配置的参数
egrep -v "^$|^#" /etc/neutron/plugins/ml2/linuxbridge_agent.ini

nova_metadata_host = controller-01
metadata_proxy_shared_secret = metadata      # METADATA_SECRET自定义设置为metadata
  • 检查配置的参数
egrep -v "^$|^#" /etc/neutron/metadata_agent.ini

配置计算服务使用网络服务

  • 编辑/etc/nova/nova.conf文件，配置如下参数
[neutron]
url = http://controller-01:9696
auth_url = http://controller-01:35357

user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = neutron
service_metadata_proxy = true
metadata_proxy_shared_secret = metadata
  • 检查配置的参数
