• OpenStack 计算服务 Nova介绍和控制节点部署 (八)


    一)nova在keystone上服务注册 

    1.1创建nova务实体

    [root@controller ~]# source admin-openrc
    
    [root@controller ~]# openstack service create --name nova 
    > --description "OpenStack Compute" compute
    +-------------+----------------------------------+
    | Field | Value |
    +-------------+----------------------------------+
    | description | OpenStack Compute |
    | enabled | True |
    | id | ef8e29299ab9413797952c01f30c45a7 |
    | name | nova |
    | type | compute |
    +-------------+----------------------------------+
    
    [root@controller ~]# openstack endpoint create --region RegionOne 
    > compute public http://controller:8774/v2.1/%(tenant_id)s
    +--------------+-------------------------------------------+
    | Field | Value |
    +--------------+-------------------------------------------+
    | enabled | True |
    | id | 2440e5576e994e6bb22326e52cb60587 |
    | interface | public |
    | region | RegionOne |
    | region_id | RegionOne |
    | service_id | ef8e29299ab9413797952c01f30c45a7 |
    | service_name | nova |
    | service_type | compute |
    | url | http://controller:8774/v2.1/%(tenant_id)s |
    +--------------+-------------------------------------------+
    
    [root@controller ~]# openstack endpoint create --region RegionOne 
    > compute internal http://controller:8774/v2.1/%(tenant_id)s
    +--------------+-------------------------------------------+
    | Field | Value |
    +--------------+-------------------------------------------+
    | enabled | True |
    | id | b2b525624a1e428aa673f38b2fa53542 |
    | interface | internal |
    | region | RegionOne |
    | region_id | RegionOne |
    | service_id | ef8e29299ab9413797952c01f30c45a7 |
    | service_name | nova |
    | service_type | compute |
    | url | http://controller:8774/v2.1/%(tenant_id)s |
    +--------------+-------------------------------------------+
    
    [root@controller ~]# openstack endpoint create --region RegionOne 
    > compute admin http://controller:8774/v2.1/%(tenant_id)s
    +--------------+-------------------------------------------+
    | Field | Value |
    +--------------+-------------------------------------------+
    | enabled | True |
    | id | 9507672587aa4cfaaa838f05ce4dcdb4 |
    | interface | admin |
    | region | RegionOne |
    | region_id | RegionOne |
    | service_id | ef8e29299ab9413797952c01f30c45a7 |
    | service_name | nova |
    | service_type | compute |
    | url | http://controller:8774/v2.1/%(tenant_id)s |
    +--------------+-------------------------------------------+
    

    二)安装配置nova

    2.1安装软件包

    # yum install openstack-nova-api openstack-nova-conductor openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler -y
    

    2.2 配置数据库

    #vim /etc/nova/nova.conf
    
    
    [DEFAULT]
    enabled_apis = osapi_compute,metadata    #设置启用的元数据API
    transport_url = rabbit://openstack:redhat@controller     #(消息队列配置)
    auth_strategy = keystone
    my_ip = 10.0.0.101
    use_neutron = True                                        #启动网络服务支持和关闭防火墙
    firewall_driver = nova.virt.firewall.NoopFirewallDriver
    
    [database]
    connection = mysql+pymysql://nova:redhat@controller/nova      #配置nova数据库连接
    
    [api_database]
    connection = mysql+pymysql://nova:redhat@controller/nova_api   #配置nova-api数据库连接
     
    [keystone_authtoken]                                         #配置keystone
    auth_uri = http://controller:5000
    auth_url = http://controller:35357
    memcached_servers = controller:11211
    auth_type = password
    project_domain_name = Default
    user_domain_name = Default
    project_name = service
    username = nova
    password = redhat
    
    [vnc]                                                   #配置VNC代理使用控制节点的管理接口IP地址
    vncserver_listen = $my_ip
    vncserver_proxyclient_address = $my_ip
    
    [glance]                                               #配置镜像服务 API 的位置
    api_servers = http://controller:9292
    
    [oslo_concurrency]                                      #配置锁路径
    lock_path = /var/lib/nova/tmp
    

    2.3 同步数据库

    su -s /bin/sh -c "nova-manage api_db sync" nova
    su -s /bin/sh -c "nova-manage db sync" nova

    提示:有警告可以忽略

    2.4 设置开机启动,并启动服务

    systemctl enable openstack-nova-api.service 
    openstack-nova-consoleauth.service openstack-nova-scheduler.service 
    openstack-nova-conductor.service openstack-nova-novncproxy.service
    
    systemctl start openstack-nova-api.service 
    openstack-nova-consoleauth.service openstack-nova-scheduler.service 
    openstack-nova-conductor.service openstack-nova-novncproxy.service
    

    2.5 查看控制节点是否配置成功

    [root@controller ~]# openstack host list
    +------------+-------------+----------+
    | Host Name | Service | Zone |
    +------------+-------------+----------+
    | controller | consoleauth | internal |
    | controller | conductor | internal |
    | controller | scheduler | internal |
    +------------+-------------+----------+
