<一,preface Important Project Network>
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 !!!
<二,实战之ONE identity sevice>
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<user,role,tenant >
链接 _member_ role admin <user,tenant>
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
<三,install and configure the openstack >
(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;
<四,install/configure the image service>
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
