preface/pre,获取OpenStack核心模块组件及其子组件包(当前仅针对centos6*)及其依赖包
eg,picture
1,use these credentials with the Identity Service,auth mode for openstack use openstack-keystone identity service;
2,nova auth use keystone identity service(使用db(sqlite,mysql,postgresql)存储相关配infos)rpc_backend rpc_host....(Ruiy tips notices,simaliy all openStacks services components(like,keystone,glance,nova,neutron,orchestration.trove,ceilometer,swift,cinder....))
3,register compute with the identity service so that other openstack services can locate it,register the service and specify the endpoint (all like other openStack services components)
Ruiy tips:typical all openStack services 使用service tenant addon admin role,component name as user name;
4,openStack service components,sub components process control;
5,nova control,compute Nodes ERROR: Unauthorized (HTTP 401)
6,nova conn image service,ERROR: [Errno 111] Connection refused
7,neutron
