安装 Nova

本节介绍的是 Nova 端点服务配置，而非计算节点本身。

如何安装并配置 Nova

1. 通过在 /etc/nova/nova.conf 文件中取消注释或设置参数来配置 Nova。

   [DEFAULT]
   my_ip=$CONTROLLER_ADMIN_NODE_IP
   host=$CONTROLLER_ADMIN_NODE
   firewall_driver=nova.virt.firewall.NoopFirewallDriver
   
   [database]
   connection = mysql://nova:service-password@$CONTROLLER_ADMIN_NODE/nova
   
   [glance]
   host=$CONTROLLER_ADMIN_NODE
   
   [keystone_authtoken]
   auth_uri=http://$CONTROLLER_ADMIN_NODE:5000/v2.0/
   identity_uri=http://$CONTROLLER_ADMIN_NODE:35357/
   admin_user=nova
   admin_password=service-password
   admin_tenant_name=service
   
   [neutron]
   url=http://$CONTROLLER_ADMIN_NODE:9696
   admin_username=neutron
   admin_password=service-password
   admin_tenant_name=service
   admin_auth_url=http://$CONTROLLER_ADMIN_NODE:5000/v2.0
   
   [oslo_messaging_rabbit]
   rabbit_host=$CONTROLLER_ADMIN_NODE
   

2. 设置 /etc/nova/api-paste.ini 文件中的参数。

   [filter:authtoken]
   admin_user = nova
   admin_password = service-password
   admin_tenant_name = service
   auth_uri = http://$CONTROLLER_ADMIN_NODE:5000/v2.0/
   identity_uri = http://$CONTROLLER_ADMIN_NODE:35357
   

3. 启用 Nova SMF 服务。

   controller# svcadm enable -rs nova-conductor
   controller# svcadm enable -rs nova-api-osapi-compute \
   nova-cert nova-scheduler
