Ubuntu搭建Openstack平台（kilo）(五.neutron(一)控制节点)

一.neutron环境
参考文档：http://www.aboutyun.com/thread-13108-1-1.html
http://docs.openstack.org/mitaka/install-guide-ubuntu/neutron-controller-install.html
1.创建neutron数据库并授权

• 创建

mysql -u root -p

CREATE DATABASE neutron;

• 授权

GRANT ALL PRIVILEGES ON neutron.* TO ‘neutron‘@‘localhost‘ IDENTIFIED BY ‘NEUTRON_PASS‘;
GRANT ALL PRIVILEGES ON neutron.* TO ‘neutron‘@‘%‘ IDENTIFIED BY ‘NEUTRON_PASS‘;

• 退出

exit

2.生效环境变量

source admin-openrc.sh

3.创建网络用户并授权

• 创建neutron用户

openstack user create --password-prompt neutron
User Password:（我的设置neutron）
Repeat User Password:
+-----------+----------------------------------+
| Field     | Value                            |
+-----------+----------------------------------+
| domain_id | e0353a670a9e496da891347c589539e9 |
| enabled   | True                             |
| id        | b20a6692f77b4258926881bf831eb683 |
| name      | neutron                          |
+-----------+----------------------------------+

• 添加admin角色到neutron用户

openstack role add --project service --user neutron admin

• 创建neutron 服务实例

 openstack service create --name neutron --description  "OpenStack Networking" network
 +-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | OpenStack Networking             |
| enabled     | True                             |
| id          | f71529314dab4a4d8eca427e701d209e |
| name        | neutron                          |
| type        | network                          |
+-------------+----------------------------------+

• 创建网络服务API endpoint

openstack endpoint create --publicurl http://controller:9696 --adminurl http://controller:9696 --internalurl http://controller:9696 --region RegionOne network
+--------------+----------------------------------+
| Field        | Value                            |
+--------------+----------------------------------+
| adminurl     | http://controller:9696           |
| id           | 85d80a6d02fc4b7683f611d7fc1493a3 |
| internalurl  | http://controller:9696           |
| publicurl    | http://controller:9696           |
| region_id    | RegionOne                        |
| service_id   | f71529314dab4a4d8eca427e701d209e |
| service_name | neutron                          |
| service_type | network                          |
+--------------+----------------------------------+

二.安装Neutron
1.安装neutron组件

apt-get install neutron-server neutron-plugin-ml2 python-neutronclient

2.配置环境

vim /etc/neutron/neutron.conf

[DEFAULT]
verbose = True
rpc_backend = rabbit
#配置认证访问
auth_strategy = keystone

#启用 Modular Layer 2 (ML2) plug-in,路由服务, 和 overlapping IP addresses:
core_plugin = ml2
service_plugins = router
allow_overlapping_ips = True

#配置计算节点网络拓扑变化通知
notify_nova_on_port_status_changes = True
notify_nova_on_port_data_changes = True
nova_url = http://controller:8774/v2

[database]
connection = mysql://neutron:NEUTRON_DBPASS(neutron的数据库密码)@controller/neutron

[oslo_messaging_rabbit]
#配置RabbitMQ 消息队列服务
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = RABBIT_PASS(密码为创建的消息中间件密码，我的为123)

[keystone_authtoken]
#配置认证访问
auth_uri = http://controller:5000
auth_url = http://controller:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
project_name = service
username = neutron
password = NEUTRON_PASS(我的密码neutron)

[nova]
#配置计算节点网络拓扑变化通知
auth_url = http://controller:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
region_name = RegionOne
project_name = service
username = nova
password = NOVA_PASS(上一篇设置的nova密码，我的为nova)

3.配置Modular Layer 2 (ML2) plug-in

vim /etc/neutron/plugins/ml2/ml2_conf.ini

[ml2]
#启用flat,VLAN,GRE和VXLAN网络类型驱动,GRE租户网络,和OVS机制驱动:
type_drivers = flat,vlan,gre,vxlan
tenant_network_types = gre
mechanism_drivers = openvswitch

[ml2_type_gre]
#配置隧道标识符的id范围
tunnel_id_ranges = 1:1000

[securitygroup]
#启用security groups, 启用 ipset, 和 配置  OVS iptables firewall 驱动
enable_security_group = True
enable_ipset = True
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver

4.重新配置网络（修改控制节点nova.conf，添加如下内容）

vim /etc/nova/nova.conf

[DEFAULT]
#配置Apis与驱动
network_api_class = nova.network.neutronv2.api.API
security_group_api = neutron
linuxnet_interface_driver = nova.network.linux_net.LinuxOVSInterfaceDriver
firewall_driver = nova.virt.firewall.NoopFirewallDriver

[neutron]
#配置访问参数
url = http://controller:9696
auth_strategy = keystone
admin_auth_url = http://controller:35357/v2.0
admin_tenant_name = service
admin_username = neutron
admin_password = NEUTRON_PASS(密码为neutron的密码，我的为neutron)

5.同步数据库（同步之后，可以看看数据库中是否存在表，有则成功，没有则表明可能sqlite数据库没删，删除后在同步rm -f /var/lib/neutron/neutron.sqlite）

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

6.重启计算服务与网络服务

service nova-api restart
service neutron-server restart

7.验证安装

• 加载环境

source admin-openrc.sh

• 查看创建的neutron-server进程(大概是这几项，我的好像多了一项，不知道为什么）
