在上一篇中介绍了Nova的安装配置，这一篇介绍neutron
- 首先，创建neutron用户并设置密码为neutron
[root@linux-node1 ~]# openstack user create --domain default --password-prompt neutron User Password: Repeat User Password: +---------------------+----------------------------------+ | Field | Value | +---------------------+----------------------------------+ | domain_id | default | | enabled | True | | id | 0e2ce721eca14c688627df21da78cc4e | | name | neutron | | options | {} | | password_expires_at | None | +---------------------+----------------------------------+
- 给neutron用户授予admin角色
[root@linux-node1 ~]# 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 | 98cc414411714278a541de8653eefcb0 | | name | neutron | | type | network | +-------------+----------------------------------+
- 创建neutron服务API端点
openstack endpoint create --region RegionOne \ network public http://192.168.56.11:9696 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | fc0ce5260d50460399bd160db2034569 | | interface | public | | region | RegionOne | | region_id | RegionOne | | service_id | 98cc414411714278a541de8653eefcb0 | | service_name | neutron | | service_type | network | | url | http://192.168.56.11:9696 | +--------------+----------------------------------+openstack endpoint create --region RegionOne \ network internal http://192.168.56.11:9696 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | a1107a5752f149a0988ee2d63c3fce8e | | interface | internal | | region | RegionOne | | region_id | RegionOne | | service_id | 98cc414411714278a541de8653eefcb0 | | service_name | neutron | | service_type | network | | url | http://192.168.56.11:9696 | +--------------+----------------------------------+openstack endpoint create --region RegionOne \ network admin http://192.168.56.11:9696 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | 1e3729ff74bd4f59b6aa5f7c170e21d2 | | interface | admin | | region | RegionOne | | region_id | RegionOne | | service_id | 98cc414411714278a541de8653eefcb0 | | service_name | neutron | | service_type | network | | url | http://192.168.56.11:9696 | +--------------+----------------------------------+
- 验证用户和服务
[root@linux-node1 ~]# openstack user list +----------------------------------+-----------+ | ID | Name | +----------------------------------+-----------+ | 0e2ce721eca14c688627df21da78cc4e | neutron | | 27080769990347169fdc6bf81fe9ebd1 | placement | | 291f02337e514343a09a92932a86fd22 | demo | | 31a0d9b7dd5f47b4b30ed4a77500a307 | glance | | 34c7be4d612a45b4830304af29eb010e | nova | | d010fba89633421a800698b0e5300d50 | admin | +----------------------------------+-----------+ [root@linux-node1 ~]# openstack service list +----------------------------------+-----------+-----------+ | ID | Name | Type | +----------------------------------+-----------+-----------+ | 325ab5f400f14fc485eb4231dab6d74d | keystone | identity | | 344d25c79f1b412cb0c5958bd8242b2c | placement | placement | | 4c4dd5eb35324b568cd9722f174a632b | glance | image | | 98cc414411714278a541de8653eefcb0 | neutron | network | | bf254b3182e04256897e925632f171d0 | nova | compute | +----------------------------------+-----------+-----------+
在本示例中，我们选择网络为provider networks
- 编辑/etc/neutron/neutron.conf，并修改如下配置：
[DEFAULT]
auth_strategy = keystone core_plugin = ml2 service_plugins = notify_nova_on_port_status_changes = true notify_nova_on_port_data_changes = true transport_url = rabbit://openstack:openstack@192.168.56.11
[database]
connection = mysql+pymysql://neutron:neutron@192.168.56.11/neutron
[keystone_authtoken]
auth_uri = http://192.168.56.11:5000 auth_url = http://192.168.56.11:35357 memcached_servers = 192.168.56.11:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = neutron password = neutron
[nova]
auth_url = http://192.168.56.11:35357
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
配置Linux桥接代理
- 编辑/etc/neutron/plugins/ml2/linuxbridge_agent.ini，并作出如下修改：
[linux_bridge]
physical_interface_mappings = provider:eth0
[securitygroup]
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
enable_security_group = true
[vxlan]
enable_vxlan = false
- 编辑/etc/neutron/plugins/ml2/ml2_conf.ini并作出如下修改：
[ml2]
type_drivers = local,flat,vlan,gre,vxlan,geneve
tenant_network_types =
mechanism_drivers = linuxbridge
extension_drivers = port_security
[ml2_type_flat]
flat_networks = provider
[securitygroup]
enable_ipset = true
- 编辑/etc/neutron/dhcp_agent.ini ，并作出如下修改：
[DEFAULT]
interface_driver = linuxbridge
dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq enable_isolated_metadata = true
配置metadata代理
- 编辑/etc/neutron/metadata_agent.ini并作出如下修改：
[DEFAULT]
nova_metadata_host = 192.168.56.11
metadata_proxy_shared_secret = openstack
为neutron配置Nova服务
- 编辑/etc/nova/nova.conf，并作出如下修改：
[neutron] url = http://192.168.56.11:9696 auth_url = http://192.168.56.11:35357 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 = openstack
- 网络服务初始化脚本需要一个链接由/etc/neutron/plugin.ini指向ML2插件配置文件/etc/neutron/plugins/ml2/ml2_conf.ini
[root@linux-node1 ~]# ln -s /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 INFO [alembic.runtime.migration] Context impl MySQLImpl. INFO [alembic.runtime.migration] Will assume non-transactional DDL. .....
- 因为修改过Nova文件，现在需要重启Nova服务
[root@linux-node1 ~]# systemctl restart openstack-nova-api.service
[root@linux-node1 ~]#
- 启动neutron并设置为开机启动
systemctl enable neutron-server.service \ neutron-linuxbridge-agent.service neutron-dhcp-agent.service \ neutron-metadata-agent.service Created symlink from /etc/systemd/system/multi-user.target.wants/neutron- server.service to /usr/lib/systemd/system/neutron-server.service.
