在计算节点安装和配置计算服务

1、云计算基础架构平台应用 （1）安装计算服务#yum install openstack-nova-compute（2）为Nova配置数据库# openstack-config -set /etc/nova/nova.conf database connection mysql:/nova:000000controller/nova# openstack-config -set /etc/nova/nova.conf DEFAULT auth_strategy keystone# openstack-config -set /etc/nova/nova.conf keystone_authtok

2、en 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 /

3、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 000000 （3）配置Qpid消息代理#openstack-config -set /etc/nova/nova.conf DEFAULT rpc_backen

4、d qpid#openstack-config -set /etc/nova/nova.conf DEFAULT qpid_hostname controller（4）配置到虚拟机实例的远程控制台访问#openstack-config -set /etc/nova/nova.conf DEFAULT vnc_enabled True#openstack-config -set /etc/nova/nova.conf DEFAULT #openstack-config -set /etc/nova/nova.conf DEFAULT novncproxy_base_url http:/contr

5、oller:6080/vnc_auto.html （7）启动计算服务及其依赖的服务rootcompute # service libvirtd startrootcompute # service messagebus startrootcompute # service openstack-nova-compute startrootcompute # chkconfig libvirtd onrootcompute # chkconfig messagebus onrootcompute # chkconfig openstack-nova-compute on （5）指定运行映像服务的节点# openstack-config -set /etc/nova/nova.conf DE
