前言：
在这里再次强调一下，openstack社区版的组件是非常多得，详见官网：OpenStack Project Teams — OpenStack Technical Committee Governance Documents
这么多组件，能够全部都使用过的，我愿称他为猛人。
源码下载地址：OpenStack Releases: Zed 当然，别的版本的源码比如，Rocky的：OpenStack Releases: Rocky
总的来说，openstack的组件是非常多得，多到你怀疑人生的那种。
而前面我们已经安装了keystone，glance，nova，这仅仅是openstack的冰山一角，下面要安装的是neutron网络服务。
OpenStack Networking（neutron），允许创建、插入接口设备，这些设备由其他的OpenStack服务管理。插件式的实现可以容纳不同的网络设备和软件，为OpenStack架构与部署提供了灵活性。
它包含下列组件：
neutron-server
接收和路由API请求到合适的OpenStack网络插件，以达到预想的目的。
OpenStack网络插件和代理
插拔端口，创建网络和子网，以及提供IP地址，这些插件和代理依赖于供应商和技术而不同，OpenStack网络基于插件和代理为Cisco 虚拟和物理交换机、NEC OpenFlow产品，Open vSwitch,Linux bridging以及VMware NSX 产品穿线搭桥。
常见的代理L3(3层)，DHCP(动态主机IP地址)，以及插件代理。
消息队列
大多数的OpenStack Networking安装都会用到，用于在neutron-server和各种各样的代理进程间路由信息。也为某些特定的插件扮演数据库的角色，以存储网络状态
OpenStack网络主要和OpenStack计算交互，以提供网络连接到它的实例。

一，
在controller节点安装neutron（也就是192.168.123.130这个服务器）
1，
创建neutron数据库，授予合适的访问权限
登陆数据库，执行以下SQL语句（何种方式登陆都可以，比如，本地登陆或者使用Navicat这些都是可以的）：
注：注意，密码设置为neutro
CREATE DATABASE neutron; GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' IDENTIFIED BY 'neutron'; GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' IDENTIFIED BY 'neutron'; flush privileges;
2，
在keystone上创建neutron用户
openstack user create --domain default --password=neutron neutron #输出如下： [root@openstack1 ~]# openstack user create --domain default --password=neutron neutron +---------------------+----------------------------------+ | Field | Value | +---------------------+----------------------------------+ | domain_id | default | | enabled | True | | id | fc87cddefdbc4087ad48fb86a28f2e40 | | name | neutron | | options | {} | | password_expires_at | None | +---------------------+----------------------------------+
3，
将neutron添加到service项目并授予admin角色
openstack role add --project service --user neutron admin #此命令无任何输出为正确
4，
创建neutron服务实体
openstack service create --name neutron --description "OpenStack Networking" network #输出如下： [root@openstack1 ~]# openstack service create --name neutron --description "OpenStack Networking" network +-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | description | OpenStack Networking | | enabled | True | | id | fed6374c1cdd453a8d26c4e33d664b5d | | name | neutron | | type | network | +-------------+----------------------------------+
5，
创建neutron网络服务的API端点（检查点）
注：仍然使用主机名openstack1
openstack endpoint create --region RegionOne network public http://openstack1:9696 openstack endpoint create --region RegionOne network internal http://openstack1:9696 openstack endpoint create --region RegionOne network admin http://openstack1:9696 #输出如下： [root@openstack1 ~]# openstack service create --name neutron --description "OpenStack Networking" network +-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | description | OpenStack Networking | | enabled | True | | id | fed6374c1cdd453a8d26c4e33d664b5d | | name | neutron | | type | network | +-------------+----------------------------------+ [root@openstack1 ~]# openstack endpoint create --region RegionOne network public http://openstack1:9696 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | e69de8adfe8042369e05652e6961503e | | interface | public | | region | RegionOne | | region_id | RegionOne | | service_id | fed6374c1cdd453a8d26c4e33d664b5d | | service_name | neutron | | service_type | network | | url | http://openstack1:9696 | +--------------+----------------------------------+ [root@openstack1 ~]# openstack endpoint create --region RegionOne network internal http://openstack1:9696 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | a1c8d96d44154cbc85f32e5d9ff8e54e | | interface | internal | | region | RegionOne | | region_id | RegionOne | | service_id | fed6374c1cdd453a8d26c4e33d664b5d | | service_name | neutron | | service_type | network | | url | http://openstack1:9696 | +--------------+----------------------------------+ [root@openstack1 ~]# openstack endpoint create --region RegionOne network admin http://openstack1:9696 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | 5080d68d4d094baab6246608fd7d277d | | interface | admin | | region | RegionOne | | region_id | RegionOne | | service_id | fed6374c1cdd453a8d26c4e33d664b5d | | service_name | neutron | | service_type | network | | url | http://openstack1:9696 | +--------------+----------------------------------+
6，
yum安装neutron组件
yum install openstack-neutron openstack-neutron-ml2 openstack-neutron-linuxbridge ebtables -y
7，

查看表的数目：
[root@openstack1 ~]# mysql -h192.168.123.130 -uneutron -pneutron -e 'use neutron;show tables' |wc -l 168
15，重启nova服务和启动neutron服务以及加入自启
# 需要启动4个服务
systemctl restart openstack-nova-api.service 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 systemctl list-unit-files |grep nova |grep enabled
# 至此，控制端的neutron网络服务就安装完成，之后需要在计算节点安装网络服务组件，使计算节点可以连接到openstack集群
二，

6，
启动neutron网络组件，并配置开机自启动
#只需要启动1个服务，网桥代理
systemctl enable neutron-linuxbridge-agent.service systemctl restart neutron-linuxbridge-agent.service systemctl list-unit-files |grep neutron* |grep enabled
三，
在控制节点检查确认neutron服务安装是否成功

查看网络代理列表
这个是比较重要的，必须是四个笑脸才表示正常。控制节点三个客户端，计算节点一个客户端：
[root@openstack1 ~]# openstack network agent list +--------------------------------------+--------------------+------------+-------------------+-------+-------+---------------------------+ | ID | Agent Type | Host | Availability Zone | Alive | State | Binary | +--------------------------------------+--------------------+------------+-------------------+-------+-------+---------------------------+ | 0676c5ab-96ea-4f2a-83e4-85a46ecef4d4 | DHCP agent | openstack1 | nova | :-) | UP | neutron-dhcp-agent | | 13976d13-5f4e-48e5-88ab-29530b6030eb | Metadata agent | openstack1 | None | :-) | UP | neutron-metadata-agent | | 6e5d6975-8786-4e6e-81c9-624c665c0ba7 | Linux bridge agent | openstack1 | None | :-) | UP | neutron-linuxbridge-agent | | 897083ed-e704-4dfc-96b3-8c2dd721be83 | Linux bridge agent | openstack2 | None | :-) | UP | neutron-linuxbridge-agent | +--------------------------------------+--------------------+------------+-------------------+-------+-------+---------------------------+
OK，neutron服务安装完毕
