openstack部署安装(Icehouse版本)-控制节点(Controller)-计算服务(nova)
nova为计算服务，能够启动虚拟机实例。可以将这些服务配置在单独的节点或同一节点上。大多数服务在控制器节点上运行，在一个专用的计算节点上运行虚拟机运行的服务。此次，我们将compute部署到控制节点上。4.1 Install Compute controller services(安装计算服务)
4.1.1 安装compute所需要的包
# yum install openstack-nova-api openstack-nova-cert openstack-nova-conductor \
openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler \
python-novaclient
4.1.2 为nova创建数据库
# mysql -u root -p
mysql> CREATE DATABASE nova;
mysql> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' \
IDENTIFIED BY 'nova';
mysql> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' \
IDENTIFIED BY 'nova';
4.1.3 修改nova的配置文件，创建数据库连接
# openstack-config --set /etc/nova/nova.conf \
database connection mysql://nova:nova@controller/nova
4.1.4 修改nova的配置文件，使用特定的消息服务qpid。之后修改my_ip，nvc服务
# openstack-config --set /etc/nova/nova.conf \
DEFAULT rpc_backend qpid
# openstack-config --set /etc/nova/nova.conf DEFAULT qpid_hostname controller
# openstack-config --set /etc/nova/nova.conf DEFAULT my_ip 10.0.0.11
# openstack-config --set /etc/nova/nova.conf DEFAULT vncserver_listen 10.0.0.11
# openstack-config --set /etc/nova/nova.conf DEFAULT vncserver_proxyclient_address 10.0.0.1
4.1.5 为nova创建数据库表
# su -s /bin/sh -c "nova-manage db sync" nova
4.1.6 创建nova用户，并且添加到admin角色中
# keystone user-create --name=nova --pass=nova --email=nova@example.com
# keystone user-role-add --user=nova --tenant=service --role=admin
4.1.7 配置nova服务，使得一下认证在控制节点运行
# openstack-config --set /etc/nova/nova.conf DEFAULT auth_strategy keystone
# openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_uri http://controller:5000
# openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_host controller
# openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_protocol http
# openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_port 35357
# openstack-config --set /etc/nova/nova.conf keystone_authtoken admin_user nova
# openstack-config --set /etc/nova/nova.conf keystone_authtoken admin_tenant_name service
# openstack-config --set /etc/nova/nova.conf keystone_authtoken admin_password nova
4.1.8 创建nova服务，并且创建endpoint
# keystone service-create --name=nova --type=compute \
--description="OpenStack Compute"
# keystone endpoint-create \
--service-id=$(keystone service-list | awk '/ compute / {print $2}') \
--publicurl=http://controller:8774/v2/%\(tenant_id\)s \
--internalurl=http://controller:8774/v2/%\(tenant_id\)s \
--adminurl=http://controller:8774/v2/%\(tenant_id\)s
4.1.9 启动nova服务，并将nova服务加入到开机自动启动
# service openstack-nova-api start
# service openstack-nova-cert start
# service openstack-nova-consoleauth start
# service openstack-nova-scheduler start
# service openstack-nova-conductor start
# service openstack-nova-novncproxy start
# chkconfig openstack-nova-api on
# chkconfig openstack-nova-cert on
# chkconfig openstack-nova-consoleauth on
# chkconfig openstack-nova-scheduler on
# chkconfig openstack-nova-conductor on
# chkconfig openstack-nova-novncproxy on
4.1.10 查看nova服务是否安装正常
# nova image-list
+--------------------------------------+---------------------+--------+--------+
| ID | Name | Status | Server |
+--------------------------------------+---------------------+--------+--------+
| asjkd7d3-78kl-3783-7873-b878784e1fj3 | cirros-0.3.2-x86_64 | ACTIVE | |
+--------------------------------------+---------------------+--------+--------+
到此，nova服务已经安装完成。如果以上身份认证问题，执行以下 source admin.sh
