  安装NTP服务

 

yum install -y ntp

/etc/init.d/ntpd start

   chkconfig ntpd on

四、           安装nova-compute

  安装mysql-dev 和 compute

 

yum install -y mysql-devel openstack-utilsopenstack-nova-compute

 

  配置node01的nova验证

 

openstack-config--set /etc/nova/nova.conf database connection mysql://nova:openstack@openstack/nova

openstack-config--set /etc/nova/nova.conf DEFAULT auth_strategy keystone

openstack-config--set /etc/nova/nova.conf DEFAULT auth_host openstack

openstack-config--set /etc/nova/nova.conf DEFAULT admin_user nova

openstack-config--set /etc/nova/nova.conf DEFAULT admin_tenant_name service

openstack-config--set /etc/nova/nova.conf DEFAULT admin_password openstack

 

vi/etc/nova/api-paste.ini

 

[filter:authtoken]

paste.filter_factory=keystoneclient.middleware.auth_token:filter_factory

auth_host=openstack

auth_port=35357

auth_protocol=http

admin_user=nova

admin_tenant_name=service

admin_password=openstack

 

 

  配置node01的nova连接qpid

 

openstack-config--set /etc/nova/nova.conf DEFAULT rpc_backendnova.openstack.common.rpc.impl_qpid

openstack-config--set /etc/nova/nova.conf DEFAULT qpid_hostname openstack

 

  配置VNC相关服务

openstack-config--set /etc/nova/nova.conf DEFAULT vncserver_listen 192.168.1.201

openstack-config--set /etc/nova/nova.conf DEFAULT vncserver_proxyclient_address 192.168.1.201

 

  指定imageservice

 

openstack-config --set/etc/nova/nova.conf DEFAULT glance_host openstack

 

  设置computenode相关服务启动

 

servicelibvirtd start

servicemessagebus start

serviceopenstack-nova-compute start

chkconfiglibvirtd on

chkconfigmessagebus on

chkconfigopenstack-nova-compute on

 

五、           安装nova-network

  节点安装openstack-nova-network服务
