安装Nova
Nova提供在統一的計算資源抽象
安装必备条件
- 使用root帐号登录数据库
mysql -u root -p
- 创建nova_api, nova, 及 nova_cell0 数据库
MariaDB [(none)]> CREATE DATABASE nova_api;
MariaDB [(none)]> CREATE DATABASE nova;
MariaDB [(none)]> CREATE DATABASE nova_cell0;
- 配置权限
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' \
IDENTIFIED BY 'NOVA_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' \
IDENTIFIED BY 'NOVA_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' \
IDENTIFIED BY 'NOVA_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' \
IDENTIFIED BY 'NOVA_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' \
IDENTIFIED BY 'NOVA_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' \
IDENTIFIED BY 'NOVA_DBPASS';

安装及配置组件
- 安装软件包
yum install openstack-nova-api openstack-nova-conductor \
openstack-nova-console openstack-nova-novncproxy \
openstack-nova-scheduler openstack-nova-placement-api
- 配置/etc/nova/nova.conf文件
- 在[DEFAULT]字段中,设置API
[DEFAULT]
# ...
enabled_apis = osapi_compute,metadata
- 在 [api_database]及[database]字段设置数据库接入许可
[api_database]
# ...
connection = mysql+pymysql://nova:NOVA_DBPASS@controller/nova_api
[database]
# ...
connection = mysql+pymysql://nova:NOVA_DBPASS@controller/nova
- 在[DEFAULT]字段, 设置RabbitMQ消息队列接入权限
[DEFAULT]
# ...
transport_url = rabbit://openstack:RABBIT_PASS@controller
- 在[api]及[keystone_authtoken]字段中,设置身份验证服务
[api]
# ...
auth_strategy = keystone
[keystone_authtoken]
# ...
auth_url = http://controller:5000/v3
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = nova
password = NOVA_PASS
- 在[DEFAULT]字段中,设置 my_ip 选项，为控制节点的IP地址
[DEFAULT]
# ...
my_ip = 192.168.125.115
- 在[DEFAULT]字段,开启网络服务
[DEFAULT]
# ...
use_neutron = True
firewall_driver = nova.virt.firewall.NoopFirewallDriver
- 在 [vnc] 字段中，设置 VNC代理为控制节点的IP
[vnc]
enabled = true
# ...
server_listen = $my_ip
server_proxyclient_address = $my_ip
- 在[glance] 字段, 设置镜像服务API:
[glance]
# ...
api_servers = http://controller:9292
- 在[oslo_concurrency] 字段, 配置 lock 路径
[oslo_concurrency]
# ...
lock_path = /var/lib/nova/tmp
- 由于软件包的一个bug，需要在/etc/httpd/conf.d/00-nova-placement-api.conf文件中添加如下配置
<Directory /usr/bin>
<IfVersion >= 2.4>
Require all granted
</IfVersion>
<IfVersion < 2.4>
Order allow,deny
Allow from all
</IfVersion>
</Directory>
- 重新http服务
systemctl restart httpd
- 同步nova-api数据库
su -s /bin/sh -c "nova-manage api_db sync" nova
出现警告 /usr/lib/python2.7/site-packages/oslo_db/sqlalchemy/enginefacade.py:332: NotSupportedWarning: Configuration option(s) ['use_tpool'] not supported
exception.NotSupportedWarning
将.py文件中332的语句注释掉
- 注册cell0 数据库
su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
- 创建cell1 cell
su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova 109e1d4b-536a-40d0-83c6-5f121b82b650
- 同步nova数据库
su -s /bin/sh -c "nova-manage db sync" nova
- 验证 nova、 cell0、 cell1数据库是否注册正确
# nova-manage cell_v2 list_cells
+-------+--------------------------------------+
| Name | UUID |
+-------+--------------------------------------+
| cell1 | 109e1d4b-536a-40d0-83c6-5f121b82b650 |
