CentOS7.1 Liberty云平台之Networking篇(6)

选择Provider networks

控制节点：

一、安装配置Networking服务

1.创建数据库及管理用户

mysql -u root -p

执行以下命令

CREATE DATABASE neutron;
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' IDENTIFIED BY 'NEUTRON_DBPASS';
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' IDENTIFIED BY 'NEUTRON_DBPASS';

2.生效admin变量

source admin-openrc.sh

3.创建neutron用户

openstack user create --domain default --password-prompt neutron

添加admin角色到neutron用户及service项目

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

创建neutron服务实体

openstack service create --name neutron --description "OpenStack Networking" network

4.创建服务API端点

openstack endpoint create --region RegionOne network public http://controller:9696
openstack endpoint create --region RegionOne network internal http://controller:9696
openstack endpoint create --region RegionOne network admin http://controller:9696

5.安装neutron相关包

yum install openstack-neutron openstack-neutron-ml2 openstack-neutron-linuxbridge python-neutronclient ebtables ipset

6.配置/etc/neutron/neutron.conf

[DEFAULT]
core_plugin = ml2
service_plugins =
rpc_backend = rabbit
auth_strategy = keystone
notify_nova_on_port_status_changes = True
notify_nova_on_port_data_changes = True
nova_url = http://controller:8774/v2
verbose = True
......
[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357

user_domain_id = default
project_name = service
username = neutron
password = 111111
......
[database]
connection = mysql://neutron:NEUTRON_DBPASS@controller/neutron
......
[nova]
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 = 111111
......
[oslo_concurrency]
lock_path = /var/lib/neutron/tmp
......
[oslo_messaging_rabbit]
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = RABBIT_PASS
......

7.配置/etc/neutron/plugins/ml2/ml2_conf.ini

[ml2]
type_drivers = flat,vlan
tenant_network_types =
mechanism_drivers = linuxbridge
extension_drivers = port_security
......
[ml2_type_flat]
flat_networks = public
......
[securitygroup]
enable_ipset = True
......

8.配置/etc/neutron/plugins/ml2/linuxbridge_agent.ini

[vxlan]
enable_vxlan = False
[agent]
prevent_arp_spoofing = True
[securitygroup]
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

9.配置/etc/neutron/dhcp_agent.ini

[DEFAULT]
interface_driver = neutron.agent.linux.interface.BridgeInterfaceDriver
dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq
enable_isolated_metadata = True
verbose = True

10.配置/etc/neutron/metadata_agent.ini

[DEFAULT]
auth_uri = http://controller:5000
auth_url = http://controller:35357
auth_region = RegionOne
auth_plugin = password
project_domain_id = default
user_domain_id = default
project_name = service
username = neutron
password = 111111
nova_metadata_ip = controller
verbose = True

11.配置/etc/nova/nova.conf

[neutron]
url = http://controller:9696
auth_url = http://controller:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
region_name = RegionOne
project_name = service 
username = neutron
password = 111111
service_metadata_proxy = True
metadata_proxy_shared_secret = METADATA_SECRET

12.创建软链接

ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini

13.填充数据库

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

14.重启Compute API服务

systemctl restart openstack-nova-api.service

15.启动neutron相关服务，并设置开机自启

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

计算节点：

二、安装配置控制节点

1.安装neutron相关包

yum install openstack-neutron openstack-neutron-linuxbridge ebtables ipset -y

2.配置/etc/neutron/neutron.conf

[DEFAULT]
rpc_backend = rabbit
auth_strategy = keystone
verbose = True
......
[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357
auth_plugin = password

lock_path = /var/lib/neutron/tmp
......
[oslo_messaging_rabbit]
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = RABBIT_PASS
......

3.配置/etc/neutron/plugins/ml2/linuxbridge_agent.ini

systemctl start neutron-linuxbridge-agent.service

控制节点：

三、验证

1.生效admin脚本变量

source admin-openrc.sh

2.查看成功运行的neutron服务进程

neutron ext-list

3.查看neutron服务代理

neutron agent-list
