openstack手动玩转

长枪不倒

　　
　　openstack or all most cloud env Network desgine  is so much master!
　　openstack env arch-->Network 主要有2种,openstack networking(neutron),legacy
　　具体网络规划之前写了简单笔记,只是我去那次 没保存,我也就懒得再写了!我这人就这熊样,你懂的!
　　想真正玩转openStack,需加强熟悉其组件,组件较多(约10个左右),其功能之强大窥此也可见一斑,,所以ruiy在玩转openstack唱响的口号是,想玩转openstack,先从玩转其组件部署开始,熟不知,百尺高楼跟(根)地基!不然你永远是擦皮鞋的,一般生态论中答案只有2个,玩转;玩不转,答案咫尺天涯,待你书写 !!!
　　
　　Ruiy 提醒,在决战前先要把基本功做到位,icehource-repo;
　　1,identity server install;







　　创建admin账号;

　　创建角色,租户

　　链接admin
　　链接 _member_ role admin

　　create normal user;

　　link the demo user,_member_ role,and demo tenant;

　　Create a service tenant

　　define service and API endpoints;
　　keystone service-create. Describes the service
　　keystone endpointe-create.Associate API endpoints with the service

　　1,Create a service entry for the identity service:

　　2,specify an API endpoint for the identity service,provide url for public API,internal API,and admin API;

　　其中得注意下identity 常用的2个端口分别是35357,5000,上面我的测试环境有个事错的;
　　3,verify the identity service installtion

　　已定义的identity service variables

　　unset OS_SERVICE_TOKEN OS_SERVICE_ENDPOINT

　　web-base 验证 identity service

　　cmd验证

　　set variables



　　
　　(block storage) cinder python-cinderclient create and manage volumes;
　　compute nova python-novaclient create manage images,instances,and flavors;
　　database service trove python-troveclient create and manage databases;
　　identity keystone python-keystoneclient create manage users,tenants,roles,endpoints,and credentials;
　　image service glance python-glanceclient create and manage images;
　　networking neutron python-neutronclient configure network for guest server,this client was previosly claaed quantum;
　　object storage swift python-swiftclient gather statistics,list items,update metadata,and upload,download,and delete files stored by the object storage service,gain access to an object storage installation for ad hoc processing;
　　orchestration heat python-heatclient launch stacks from templates,view details of running stacks including events and resources,and update and delete stacks;
　　telemetry ceilometer python-ceilometerclient  create and collect measurements across openstack;
　　使用identity 列表用户 出现问题,待解决


　　1,install the openstack command-line clients
　　prerequisite software
　　python,setuptools pip;

python-pip.noarch : A tool for installing and managing Python packages
python-setuptools.noarch : Easily build and distribute Python packages
　　yum -y install python-pip python python-setuptools;

　　https://pypi.python.org/pypi/setuptools

wget https://bootstrap.pypa.io/ez_setup.py -O - | python
https://pypi.python.org/pypi/python-novaclient/
install the clients;
2,install the clients;
ceilometer -->Telemetry API
cinder --> block storage API and extensions
glance --> image service API
heat -->orchestration API
keystone -->identity service API and extensions
neutron -->etworking API
nova -->computer API and extensions
swift -->object stoage API
trove -->database service API
具体落实openstack 组件,使用pip工具

　　pip install python-PROJECTclient
　　yum -y install python-PROJECTclient;
　　基于python package install tool 升级及移除卸载安装包组件命令
　　pip install --upgrade python-PROJECTclient;
　　pip uninstall python-PROJECTclient;
　　3,set environment variables using the openstack RC file;



export OS_USERNAME=admin
export OS_PASSWORD=321
export OS_TENANT_NAME=admin
export OS_AUTH_URL=http://master.puppet.cc:35357/v2.0
expect(sshPasswdless noActive);
　　小插曲,修改数据库表,修复之前创建enpoint端口问题;

　　覆盖环境变量
　　keystone --os-password override EnvironmentVariable service-list;





　　
　　image service enables users to discover,register,and retrieve virtual machine images;
　　image service offer a reset API that enables you to query virtual machine image metadata and retrieve an actual image;
　　you can store virtual machine images made available through the image service in a variety of locations from simple file systems to object-storage systems like openstack object storage;
　　for simplicity,configures the image service are stored a directory on the same system that hosts,directory /var/lib/glance/images;
　　image service components:
　　glance-api:accept image API calls for image discovery,retrieval,and storage;
　　glance-registry:Stores,pocesses,and retrieves metadata about images,Metadata includes items such as size and type;
　　INSTALL the image service;
　　yum -y install openstack-glance python-glanceclient;

　　image service acts as a registry fo virtual disk images,users can add new image or take a snapshot of an image from an existing server for immediate storage;
　　类似identity service相关配置信息也是存储在mysql库中的;
　　配置image service 数据库存储;

　　configure the image service to use the message broker(Ruiy test environment use qpid):

　　use the password you created to log in as root and create a glance database  user:

　　创造数据表为image service

　　create a glance user that the image service can to authenticate with the identity service,choose a password and specify an email address for the glance,use the service tenant and give the admin role;

　　configure the image service to use the identity ervice for authentication;

　　register the image service with the identity service so that other openstack services can locate it,register the service and create the endpoint;

　　start the glance-api and glance-registry service and configure them start when the system boots

　　现在我们简单验证下image service;
　　CirrOS is a small test image
