一、建立數據庫python

[root@controller ~]# mysql -u root -p -e "CREATE DATABASE nova;"mysql

Enter password: linux

[root@controller ~]# mysql -u root -p -e "GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'nova';"sql

Enter password: 數據庫

[root@controller ~]# mysql -u root -p -e "GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'nova';"vim

Enter password:api

二、安裝nova安全

[root@controller ~]# yum install -y openstack-nova-api openstack-nova-cert \網絡

openstack-nova-conductor openstack-nova-console \運維

openstack-nova-novncproxy openstack-nova-scheduler \

python-novaclient

三、配置nova

3.一、同步數據庫

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

2212 connection=mysql://nova:nova@192.168.1.11/nova

[root@controller ~]# su -s /bin/sh -c "nova-manage db sync"nova

3.二、配置使用rabbimq

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

61 rpc_backend=rabbit

3949 rabbit_host=192.168.1.11

3953 rabbit_port=5672

3965 rabbit_userid=openstack

3969 rabbit_password=openstack

3.三、配置鏈接keystone

3.3.一、建立用戶

[root@controller ~]# openstack user create --domain default--password=nova nova

+-----------+----------------------------------+

| Field | Value |

+-----------+----------------------------------+

| domain_id | default |

| enabled | True |

| id |f53595ae167e40f99d13c7014e89d129 |

| name | nova |

+-----------+----------------------------------+

[root@controller ~]# openstack role add --project service --user novaadmin

3.3.二、鏈接keystone

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

425 auth_strategy=keystone

2540 [keystone_authtoken]

2541 auth_uri = http://192.168.1.11:5000

2542 auth_url = http://192.168.1.11:35357

2543 auth_plugin = password

2544 project_domain_id = default

2545 user_domain_id = default

2546 project_name = service

2547 username = nova

2548 password = nova

配置啓動網絡支持

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

1053 network_api_class=nova.network.neutronv2.api.API

1171linuxnet_interface_driver=nova.network.linux_net.NeutronLinuxBridgeInterfaceDriver

3.3.三、設置安全組

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

1331 security_group_api=neutron

1759 firewall_driver=nova.virt.firewall.NoopFirewallDriver

3.3.四、配置鏈接vnc

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

124 my_ip=192.168.1.11

1827 vncserver_listen=$my_ip

1831 vncserver_proxyclient_address=$my_ip

3.3.五、配置鏈接glance

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

2333 host=$my_ip

3.3.六、其它配置

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

268 enabled_apis=osapi_compute,metadata //去掉ec2

3794 lock_path=/var/lib/nova/tmp //鎖路徑

四、啓動nova

[root@controller ~]# systemctl enable openstack-nova-api.service \

openstack-nova-cert.service \

openstack-nova-consoleauth.service \

openstack-nova-scheduler.service \

openstack-nova-conductor.service \

openstack-nova-novncproxy.service

[root@controller ~]# systemctl start openstack-nova-api.service \

openstack-nova-cert.service \

openstack-nova-consoleauth.service \

openstack-nova-scheduler.service \

openstack-nova-conductor.service \

openstack-nova-novncproxy.servic

五、註冊nova服務

[root@controller ~]# openstack service create --name nova --description"OpenStack Compute" compute

+-------------+----------------------------------+

| Field | Value |

+-------------+----------------------------------+

| description | OpenStack Compute |

| enabled | True |

| id |04090a0c01b04e4f99dc4d6bac0ff2ab |

| name | nova |

| type | compute |

+-------------+----------------------------------+

[root@controller ~]# openstack endpoint create --region RegionOne computepublic http://192.168.1.11:8774/v2/%$tenant_id$s

+--------------+-------------------------------------------+

| Field | Value |

+--------------+-------------------------------------------+

| enabled | True |

| id |5a26b6043c804a71bcd58da2eca649c7 |

| interface | public |

| region | RegionOne |

| region_id | RegionOne |

| service_id |04090a0c01b04e4f99dc4d6bac0ff2ab |

| service_name | nova |

| service_type | compute |

| url |http://192.168.1.11:8774/v2/%(tenant_id)s |

+--------------+-------------------------------------------+

root@controller ~]# openstack endpoint create --region RegionOne computeinternal http://192.168.1.11:8774/v2/%$tenant_id$s

+--------------+-------------------------------------------+

| Field | Value |

+--------------+-------------------------------------------+

| enabled | True |

| id | 9e63e12071f44ded8ec0f34c1f8d69ab |

| interface | internal |

| region | RegionOne |

| region_id | RegionOne |

| service_id | 04090a0c01b04e4f99dc4d6bac0ff2ab |

| service_name | nova |

| service_type | compute |

| url |http://192.168.1.11:8774/v2/%(tenant_id)s |

+--------------+-------------------------------------------+

[root@controller ~]#

[root@controller ~]# openstack endpoint create --region RegionOne computeadmin http://192.168.1.11:8774/v2/%$tenant_id$s

+--------------+-------------------------------------------+

| Field | Value |

+--------------+-------------------------------------------+

| enabled | True |

| id |ff0f0a2109a04e698d7dddac85700a1f |

| service_name | nova |

| service_type | compute |

| url |http://192.168.1.11:8774/v2/%(tenant_id)s |

+--------------+-------------------------------------------+

六、查看驗證

[root@controller ~]# openstack host list

+------------+-------------+----------+

| Host Name | Service | Zone |

+------------+-------------+----------+

| controller | consoleauth | internal |

| controller | scheduler |internal |

| controller | cert |internal |
