nova的作用：
nova各个组件的基本作用
nova-scheduler
前提：source admin-openstack
6.1.创建nova和nova_api数据库
mysql> CREATE DATABASE nova_api mysql> CREATE DATABASE nova;
6.2.数据库进行授权
mysql> GRANT ALL PRIVILEGES ON nova_api.* TO ‘nova‘@‘localhost‘ IDENTIFIED BY ‘nova‘; mysql> GRANT ALL PRIVILEGES ON nova_api.* TO ‘nova‘@‘%‘ IDENTIFIED BY ‘nova‘; mysql> GRANT ALL PRIVILEGES ON nova.* TO ‘nova‘@‘localhost‘ IDENTIFIED BY ‘nova‘; mysql> GRANT ALL PRIVILEGES ON nova.* TO ‘nova‘@‘%‘ IDENTIFIED BY ‘nova‘;
6.3 创建nova用户 nova密码
openstack user create --domain default --password-prompt nova User Password: Repeat User Password: +---------------------+----------------------------------+ | Field | Value | +---------------------+----------------------------------+ | domain_id | default | | enabled | True | | id | 8a7dbf5279404537b1c7b86c033620fe | | name | nova | | password_expires_at | None | +---------------------+----------------------------------+
6.4 给nova添加admin的角色
openstack role add --project service --user nova admi
6.5 创建nova项目
openstack service create --name nova --description "OpenStack Compute" compute +-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | description | OpenStack Compute | | enabled | True | | id | 060d59eac51b4594815603d75a00aba2 | | name | nova | | type | compute | +-------------+----------------------------------+
6.6 创建控制节点的endopint
openstack endpoint create --region RegionOne compute public http://192.168.56.11:8774/v2.1/%\(tenant_id\)s +--------------+-------------------------------------------+ | Field | Value | +--------------+-------------------------------------------+ | enabled | True | | id | 3c1caa473bfe4390a11e7177894bcc7b | | interface | public | | region | RegionOne | | region_id | RegionOne | | service_id | 060d59eac51b4594815603d75a00aba2 | | service_name | nova | | service_type | compute | | url | http://controller:8774/v2.1/%(tenant_id)s | +--------------+-------------------------------------------+ openstack endpoint create --region RegionOne compute internal http://192.168.56.11:8774/v2.1/%\(tenant_id\)s +--------------+-------------------------------------------+ | Field | Value | +--------------+-------------------------------------------+ | enabled | True | | id | e3c918de680746a586eac1f2d9bc10ab | | interface | internal | | region | RegionOne | | region_id | RegionOne | | service_id | 060d59eac51b4594815603d75a00aba2 | | service_name | nova | | service_type | compute | | url | http://controller:8774/v2.1/%(tenant_id)s | +--------------+-------------------------------------------+ openstack endpoint create --region RegionOne compute admin http://192.168.56.11:8774/v2.1/%\(tenant_id\)s +--------------+-------------------------------------------+ | Field | Value | +--------------+-------------------------------------------+ | enabled | True | | id | 38f7af91666a47cfb97b4dc790b94424 | | interface | admin | | region | RegionOne | | region_id | RegionOne | | service_id | 060d59eac51b4594815603d75a00aba2 | | service_name | nova | | service_type | compute | | url | http://controller:8774/v2.1/%(tenant_id)s | +--------------+-------------------------------------------+
6.7 安装软件包nova 除了nova的计算节点
yum install openstack-nova-api openstack-nova-conductor openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler
6.8 修改nova的配置文件
[[email protected] ~]# grep ‘^[a-Z]‘ /etc/nova/nova.conf auth_strategy=keystone #使用kestone认证 use_neutron=True #使用neutron的网络 enabled_apis=osapi_compute,metadata #支持的API模型 firewall_driver = nova.virt.firewall.NoopFirewallDriver #防火墙驱动 connection=mysql+pymysql://nova:[email protected]/nova_api #keystone认证 connection=mysql+pymysql://nova:[email protected]/nova api_servers=http://192.168.56.11:9292 auth_uri = http://192.168.56.11:5000 auth_url = http://192.168.56.11:35357 memcached_servers = 192.168.56.11:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = nova password = nova lock_path=/var/lib/nova/tmp #锁文件 transport_url=rabbit://openstack:[email protected] #消息队列 vncserver_listen=0.0.0.0 #vnc监听的IP vncserver_proxyclient_address=192.168.56.11 #vncproxy h5的界面化工具 [[email protected] ~]#
6.9 同步书nova的数据库和nova-api的 数据库
# su -s /bin/sh -c "nova-manage api_db sync" nova # su -s /bin/sh -c "nova-manage db sync" nova
6.10 启动计算节点
# 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.servic
6.11 验证最后的成功
[[email protected] nova]# openstack host list +-------------+-------------+----------+ | Host Name | Service | Zone | +-------------+-------------+----------+ | linux-node1 | consoleauth | internal | | linux-node1 | conductor | internal | | linux-node1 | scheduler | internal | +-------------+-------------+----------+ [[email protected] nova]#
