一、实验目的:

1、理解nova服务在OpenStack中的作用

2、掌握在控制节点上安装配置nova的方法和步骤

3、掌握在计算节点上安装与配置nova的方法和步骤

二、实验步骤:

1、在controller节点上为nova创建数据库,并创建管理账号,参考命令

建立nova的数据库:

  #mysql -u root -p (用数据库连接客户端以 root 用户连接到数据库服务器)

  #CREATE DATABASE nova_api;

  #CREATE DATABASE nova; (创建 nova_api nova 数据库:)

#CREATE DATABASE nova_cell0;

对数据库进行正确的授权:

  #GRANT ALL PRIVILEGES ON nova_api.* TO \’nova\’@\’localhost\’ \

IDENTIFIED BY \’密码\’;

  #GRANT ALL PRIVILEGES ON nova_api.* TO \’nova\’@\’%\’ \

IDENTIFIED BY \’密码\’;

  #GRANT ALL PRIVILEGES ON nova.* TO \’nova\’@\’localhost\’ \

IDENTIFIED BY \’密码\’;

  #GRANT ALL PRIVILEGES ON nova.* TO \’nova\’@\’%\’ \

IDENTIFIED BY \’密码\’;

#GRANT ALL PRIVILEGES ON nova_cell0.* TO \’nova\’@\’localhost\’ \

IDENTIFIED BY \’密码\’;

#GRANT ALL PRIVILEGES ON nova_cell0.* TO \’nova\’@\’%\’ \

IDENTIFIED BY \’密码\’

创建三个数据库:

 

 

 

授权:

 

 

 

2、在keystone中为nova创建用户、角色、服务和API接口,参考命令

#. admin-openrc

创建nova用户:

#openstack user create –domain default  –password-prompt nova

 

 

 

#openstack role add –project service –user nova admin

nova用户添加到admin角色中:

 

创建 nova 服务实体:

#openstack service create –name nova –description “OpenStack Compute” compute

 

 

 

创建 Compute 服务 API 端点:

#openstack endpoint create –region RegionOne \

compute public http://controller:8774/v2.1

 

 

 

#openstack endpoint create –region RegionOne \

compute internal http://controller:8774/v2.1

 

 

 

#openstack endpoint create –region RegionOne \

compute admin http://controller:8774/v2.1

 

 

 

#openstack user create –domain default –password-prompt placement

 

 

 

#openstack role add –project service –user placement admin

 

 

 

#openstack service create –name placement –description “Placement API” placement

 

 

 

#openstack endpoint create –region RegionOne placement public http://controller:8778

 

 

 

# openstack endpoint create –region RegionOne placement internal http://controller:8778

 

 

 

#openstack endpoint create –region RegionOne placement admin http://controller:8778

 

 

 

3、在控制节点上安装nova,参考命令如下

# yum install openstack-nova-api openstack-nova-conductor \

openstack-nova-console openstack-nova-novncproxy \

openstack-nova-scheduler openstack-nova-placement-api

 

 

 

4、参考文档修改配置文件

5、启动nova服务

重启httpd 服务:

#systemctl restart httpd

 

填充nova-api数据库:

#su -s /bin/sh -c “nova-manage api_db sync” nova

 

注册cell0数据库:

 #su -s /bin/sh -c “nova-manage cell_v2 map_cell0” nova

 

创建cell1单元格

#su -s /bin/sh -c “nova-manage cell_v2 create_cell –name=cell1 –verbose” nova

 

 

 

填充新星数据库:

su -s /bin/sh -c “nova-manage db sync” nova

 

 

 

验证nova cell0cell1是否正确注册:

nova-manage cell_v2 list_cells

正确注册:

 

设置开机自启动

#systemctl enable openstack-nova-api.service \

openstack-nova-consoleauth.service openstack-nova-scheduler.service \

openstack-nova-conductor.service openstack-nova-novncproxy.service

启动服务

# systemctl start openstack-nova-api.service \

openstack-nova-consoleauth.service openstack-nova-scheduler.service \

openstack-nova-conductor.service openstack-nova-novncproxy.service

 

6、安装并配置计算节点

7、验证

#. admin-openrc

#openstack compute service list

 

 

这里有问题,status应该为up,后来查阅了很多资料修改正确

此供参考

 输出正常即为配置正确

#openstack catalog list

 

 

 

#openstack image list

 

 

 

#nova-status upgrade check
