**首先非常抱歉，最近一直比较忙没有更新。**

**安装****neutron**

\[root@compute ~\]\# yum install -y openstack-neutronopenstack-neutron-linuxbridge ebtables ipset

**配置****neutron**

控制节点和计算节点的配置一样，可以直接从控制节点拷贝。

\[root@controller ~\]\# scp /etc/neutron/neutron.conf 192.168.1.12:/etc/neutron/

\[root@controller ~\]\# scp /etc/neutron/plugins/ml2/linuxbridge\_agent.ini192.168.1.12:/etc/neutron/plugins/ml2/

\[root@controller ~\]\# scp /etc/neutron/plugins/ml2/ml2\_conf.ini192.168.1.12:/etc/neutron/plugins/ml2

\[root@compute ~\]\# ln -s /etc/neutron/plugins/ml2/ml2\_conf.ini/etc/neutron/plugin.ini

**配置****nova**

\[root@compute ~\]\# vim /etc/nova/nova.conf

3031 \[neutron\]

3032 url = http://192.168.1.11:9696

3033 auth\_url = http://192.168.1.11:35357

3034 auth\_plugin = password

3035 project\_domain\_id = default

3036 user\_domain\_id = default

3037 region\_name = RegionOne

3038 project\_name = service

3039 username = neutron

3040 password = neutron

**启动服务**

\[root@compute ~\]\# systemctl restart openstack-nova-compute

\[root@compute ~\]\# systemctl enable neutron-linuxbridge-agent.service

\[root@compute ~\]\# systemctl start neutron-linuxbridge-agent.service

**查看验证**

\[root@controller ~\]\# neutron agent-list

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

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

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

有四行就表明安装成功

**创建网络**

\[root@controller ~\]\# neutron net-create flat --shared--provider:physical\_network physnet1 --provider:network\_type flat

Created a new network:

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

| Field |Value |

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

| admin\_state\_up |True |

| id |d9aa89ae-01ba-4a3d-b553-7e63d48d0acb |

| mtu |0 |

| name |flat |

| port\_security\_enabled |True |

| provider:network\_type |flat |

| provider:physical\_network | physnet1 |

| provider:segmentation\_id | |

| router:external |False |

| shared |True |

| status |ACTIVE |

| subnets | |

| tenant\_id |69d1967e59d247e6b7c4c3937d5baa89 |

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

\[root@controller ~\]\# neutron net-list

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

| id | name | subnets |

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

| d9aa89ae-01ba-4a3d-b553-7e63d48d0acb | flat |a645f499-90a2-4e90-8bcb-f9040392c6bb 192.168.1.0/24 |

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

**创建子网**

\[root@controller ~\]\# neutron subnet-create flat 192.168.1.0/24 --nameflat-subnet --allocation-pool start=192.168.1.100,end=192.168.1.200--dns-nameserver 192.168.1.1 --gateway 192.168.1.1

Created a new subnet:

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

| Field | Value |

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

| allocation\_pools | \{"start":"192.168.1.100", "end": "192.168.1.200"\} |

| cidr |192.168.1.0/24 |

| dns\_nameservers |192.168.1.1 |

| enable\_dhcp | True |

| gateway\_ip |192.168.1.1 |

| host\_routes | |

| id |a645f499-90a2-4e90-8bcb-f9040392c6bb |

| ip\_version | 4 |

| ipv6\_address\_mode | |

| ipv6\_ra\_mode | |

| name |flat-subnet |

| network\_id |d9aa89ae-01ba-4a3d-b553-7e63d48d0acb |

| subnetpool\_id | |

| tenant\_id |69d1967e59d247e6b7c4c3937d5baa89 |

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

\[root@controller ~\]\# neutron subnet-list

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

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

| a645f499-90a2-4e90-8bcb-f9040392c6bb | flat-subnet | 192.168.1.0/24 |\{"start": "192.168.1.100", "end":"192.168.1.200"\} |

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

此时网络、存储（本地存储）、镜像已经完全具备，因此即使不安装cinder、dashboard就可以创建一台虚拟机了。下节就开始创建第一台虚拟机。
