openstack部署（三）
控制节点（controller）-增加networking
Networking又叫做Neutron，是Openstack必不可少的组件，它其实是网络虚拟化的实现工具，可以让我们模拟出路由器、交换机、网卡等网络设备。
关于Neutron的电子书 https://yeasy.gitbooks.io/openstack_understand_neutron/content/
Neutron支持两种网络模式，第一种是非常简单的网络架构，它仅支持是让实例连接外网，不支持自定义网络、路由器以及浮动ip。只有管理员或者授权的用户有权限去管理网络。第二种网络功能比较强大，支持自定义网络管理，支持自建路由器并且也支持浮动ip。即使没有授权的用户也可以管理网络，支持用户自己配置和管理。
创建库、授权账号
[root@controller ~]# mysql -uroot -proot
MariaDB [(none)]> create database neutron;
MariaDB [(none)]>GRANT ALL PRIVILEGES ON neutron.* TO ‘neutron‘@‘localhost‘ IDENTIFIED BY ‘neutron‘;
MariaDB [(none)]>GRANT ALL PRIVILEGES ON neutron.* TO ‘neutron‘@‘%‘ IDENTIFIED BY ‘neutron‘;
MariaDB [(none)]> create database neutron; Query OK, 1 row affected (0.02 sec) MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO ‘neutron‘@‘localhost‘ IDENTIFIED BY ‘neutron‘; Query OK, 0 rows affected (0.10 sec) MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO ‘neutron‘@‘%‘ IDENTIFIED BY ‘neutron‘; Query OK, 0 rows affected (0.00 sec) MariaDB [(none)]> flush privileges; Query OK, 0 rows affected (0.04 sec) MariaDB [(none)]>
执行脚本 source admin-openrc.sh
创建neutron用户（密码为neutronpasswd）
openstack user create --domain default --password-prompt neutron
[root@controller ~]# openstack user create --domain default --password-prompt neutron User Password: Repeat User Password: +-----------+----------------------------------+ | Field | Value | +-----------+----------------------------------+ | domain_id | default | | enabled | True | | id | 84888f7a68e74de7aa64b5f00b2c319b | | name | neutron | +-----------+----------------------------------+ [root@controller ~]#
把admin角色添加到neutron用户里
openstack role add --project service --user neutron admin
[root@controller ~]# openstack role add --project service --user neutron admin
创建neutron实例
openstack service create --name neutron --description "OpenStack Networking" network
[root@controller ~]# openstack service create --name neutron --description "OpenStack Networking" network +-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | description | OpenStack Networking | | enabled | True | | id | adef74a465484941a373599f2f3ca3dc | | name | neutron | | type | network | +-------------+----------------------------------+ [root@controller ~]#
创建networking服务api终端
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
[root@controller ~]# openstack endpoint create --region RegionOne network public http://controller:9696 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | 21f6dc6d05c4433d8f56a84119c6e857 | | interface | public | | region | RegionOne | | region_id | RegionOne | | service_id | adef74a465484941a373599f2f3ca3dc | | service_name | neutron | | service_type | network | | url | http://controller:9696 | +--------------+----------------------------------+ [root@controller ~]# [root@controller ~]# openstack endpoint create --region RegionOne network internal http://controller:9696 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | 97d78cd451d94525a7fc5b456f5dd8d1 | | interface | internal | | region | RegionOne | | region_id | RegionOne | | service_id | adef74a465484941a373599f2f3ca3dc | | service_name | neutron | | service_type | network | | url | http://controller:9696 | +--------------+----------------------------------+ [root@controller ~]# [root@controller ~]# openstack endpoint create --region RegionOne network admin http://controller:9696 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | 5edccd10210a4fc187091f427b447310 | | interface | admin | | region | RegionOne | | region_id | RegionOne | | service_id | adef74a465484941a373599f2f3ca3dc | | service_name | neutron | | service_type | network | | url | http://controller:9696 | +--------------+----------------------------------+ [root@controller ~]#
安装组件
yum install openstack-neutron openstack-neutron-ml2 \
openstack-neutron-linuxbridge python-neutronclient ebtables ipset
配置服务端组件
