OpenStack 安装：neutron服务
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:

+---------------------+----------------------------------+
- 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 \

- 验证用户和服务
[root@linux-node1 ~]# openstack user list

+----------------------------------+-----------+-----------+
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:
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.
Created symlink from /etc/systemd/system/multi-user.target.wants/neutron-
