Controller：
yum install openstack-nova-api openstack-nova-cert openstack-nova-conductor \
openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler python-novaclient
配置nova的数据库连接：
openstack-config --set /etc/nova/nova.conf \
database connection mysql://nova:[email protected]/nova
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 10.0.0.10
openstack-config --set /etc/nova/nova.conf DEFAULT vncserver_listen 10.0.0.10
openstack-config --set /etc/nova/nova.conf DEFAULT vncserver_proxyclient_address 10.0.0.10
初始化nova数据库：
mysql -u root -popenstack
mysql> CREATE DATABASE nova;
mysql> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' \
IDENTIFIED BY 'openstack';
mysql> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' \
IDENTIFIED BY 'openstack';
创建nova数据库表：
su -s /bin/sh -c "nova-manage db sync" nova
keystone user-create --name=nova --pass=nova [email protected]
keystone user-role-add --user=nova --tenant=service --role=admin
配置nova服务的消息认证：
openstack-config --set /etc/nova/nova.conf DEFAULT auth_strategy keystone
openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_uri http://10.0.0.10:5000
openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_host 10.0.0.10
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
创建nova服务及端口：
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

判断你的电脑是否支持硬件加速化
egrep -c '(vmx|svm)' /proc/cpuinfo
返回为0
openstack-config --set /etc/nova/nova.conf libvirt virt_type qemu
返回为大于0的数：不做。
启动服务，加入到开机启动
service libvirtd restart
service messagebus restart
service openstack-nova-compute restart
chkconfig libvirtd on
chkconfig messagebus on
chkconfig openstack-nova-compute on

没有控制节点的nova-compute服务，解决办法：
重启controller节点的所有关于nova的服务，在重启控制节点的nova服务。
