理论：openstack管理三大资源：计算资源、网络资源，存储资源，就比如一台电脑需要cpu、内存
，网卡，硬盘。
------------------------------------------------------------------------------------
openstack各个服务的功能详解：
服务名称 项目名称 描述
Dashbiard Horizon 基于openstack API接口使用diango开发的web管理
compute Nova 通过虚拟化技术提供计算资源池
Networking Neutron 实现了虚拟机的网络资源管理
------------------------------------------------------------------------------------
storage(存储)
Object Storage Swift 对象存储，适用于"一次写入，多次读取"
Block Storage Cinder 块存储，提供存储资源池
------------------------------------------------------------------------------------
Shared Services(共享服务)

mysql -u root -p -e "GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'cinder';"
--------------------------------------------------------------------------------------
--------------------------------------------------------------------------------------
# yum install -y rabbitmq-server
让rabbitmq服务开机自动启动
# systemctl enable rabbitmq-server.service
启动rabbitmq服务
# systemctl start rabbitmq-server.service
---------------------------------------------------------------------------------------
查看端口：rabbitmq的端口是5672
# netstat -lntup
tcp6 0 0 :::5672 :::* LISTEN 2899/beam.smp
-----------------------------------------------------------------------------------------
添加一个openstack的用户名和密码：
# rabbitmqctl add_user openstack openstack ----用于用户的认证
-----------------------------------------------------------------------------------------
用户授权：
# rabbitmqctl set_permissions openstack ".*" ".*" ".*"
-----------------------------------------------------------------------------------------
列出rabbitmq的插件：
# rabbitmq-plugins list
[ ] amqp_client 3.3.5
[ ] cowboy 0.5.0-rmq3.3.5-git4b93c2d
[ ] eldap 3.3.5-gite309de4

---------------------------------------------------------------------------------------
开机自启动rabbitmq的管理插件：
# rabbitmq-plugins enable rabbitmq_management
---------------------------------------------------------------------------------------
重新启动rabbitmq:
# systemctl restart rabbitmq-server.service
---------------------------------------------------------------------------------------
再次查看监听的端口：web管理端口:15672
# netstat -lntup
tcp 0 0 0.0.0.0:15672 0.0.0.0:* LISTEN 3679/beam.smp
---------------------------------------------------------------------------------------
web端打开192.168.56.11:15672 用户名 guest 密码 guest
登录进去之后：
Admin------->复制administrator------->点击openstack------>Update this user-------->
Tags:粘帖administrator--------->密码都设置为openstack-------->logout
然后在登陆：用户名 openstack密码openstack
---------------------------------------------------------------------------------------
# yum install chrony -y
# vim /etc/chrony.conf
22 allow 192.168/16 ---将注释去掉，允许192.168网段的来连接
# systemctl enable chronyd.service 设置开机自动启动时间同步服务
# systemctl start chronyd.service 启动时间同步服务
# timedatectl set-timezone Asia/Shanghai 设置时区为东八时区

3-Keystone（上）
---------------------------------------------------------------------------------------
Keystone作用：用户与认证：用户权限与用户行为跟踪：
服务目录：提供一个服务目录，包括所有服务项与相关Api的端点
User:用户 Tenant:租户 项目 Token:令牌 Role:角色 Service:服务 Endpoint:端点
----------------------------------------------------------------------------------------
keystone安装：
# yum install -y openstack-keystone httpd mod_wsgi memcached python-memcached
# openssl rand -hex 10 ----生成随机码
aca97a2a1733e9848ab0
# grep -n '^'/etc/keystone/keystone.conf
12:admin_token = aca97a2a1733e9848ab0
107:verbose = true
495:connection = mysql://keystone:keystone@192.168.56.11/keystone
1305:servers = 192.168.56.11:11211
1710:driver = sql
1903:provider = uuid
1908:driver = memcache
-----------------------------------------------------------------------------------------------
同步数据库：注意权限，所以要用su -s 切换到keystone用户下执行：
# su -s /bin/sh -c "keystone-manage db_sync" keystone
# mysql -ukeystone -pkeystone
MariaDB [(none)]> use keystone;
Database changed

4-Keystone（下）
列出keystone修改的配置：
# grep -n '^' /etc/keystone/keystone.conf
12:admin_token = aca97a2a1733e9848ab0
107:verbose = true
495:connection = mysql://keystone:keystone@192.168.56.11/keystone
1305:servers = 192.168.56.11:11211
1710:driver = sql
1903:provider = uuid
1908:driver = memcache
----------------------------------------------------------------------------------
启动memcache服务：
# systemctl start memcached.service
---------------------------------------------------------------------------------
新建keystone配置文件，并用apache来代理它：5000正常的api来访问35357管理访问的端口
# vim /etc/httpd/conf.d/wsgi-keystone.conf
Listen 5000
Listen 35357

----------------------------------------------------------------------------------------------------
必须要配置httpd的ServerName,否则keystone服务不能起来
# grep -n '^ServerName' /etc/httpd/conf/httpd.conf
95:ServerName 192.168.56.11:80
---------------------------------------------------------------------------------------------------
启动memcache与httpd服务:
# systemctl enable memcached
# systemctl enable httpd
# systemctl start httpd
---------------------------------------------------------------------------------------------------
查看端口：
# netstat -lntup|grep httpd

5-Glance部署(镜像服务)
glance主要由三个部分组成：glance-api、glance-registry以及image store
glance-api:接受云系统镜像的创建、删除、读取请求
glance-registry：云系统的镜像注册服务
glance的安装：
# yum install -y openstack-glance python-glance python-glanceclient
修改配置文件glance-api.conf与glance-registry.conf：
# grep -n '^connection' /etc/glance/glance-api.conf
538:connection=mysql://glance:glance@192.168.56.11/glance
# grep -n '^connection' /etc/glance/glance-registry.conf
363:connection=mysql://glance:glance@192.168.56.11/glance
同步数据库：
# su -s /bin/sh -c "glance-manage db_sync" glance

6-Nova控制节点(openstack虚拟机必备组件：keystone,glance,nova,neutron)
------------------------------------------------------------------------------------------------
API:负责接收和响应外部请求，支持openstack API,EC2API
Cert:负责身份认证
Scheduler:用于云主机调度
Conductor:计算节点访问数据的中间件
Consoleleauth:用于控制台的授权验证
Novncproxy:VNC代理
Nova API组件实现了RESTful API功能，是外部访问Nova的唯一途径。
接收外部请求并通过Message Queue将请求发送给其他的服务组件，同时也兼容EC2 API,所以也可以用EC2的管理
工具对nova进行日常管理。
Nova Scheduler模块在openstack中的作用就是决策虚拟机创建在哪个主机(计算节点)上。
决策一个虚机应该调度到某物理节点，需要分两个步骤：
过滤(Fliter) 计算权值(Weight)
Fliter Scheduler首先得到未经过滤的主机列表，然后根据过滤属性，选择符合条件的计算节点主机。
经过主机过滤后，需要对主机进行权值的计算，根据策略选择相应的某一台主机(对于每一个要创建的虚拟机而言)
------------------------------------------------------------------------------------------------
安装nova控制节点：
# yum install openstack-nova-api openstack-nova-cert
openstack-nova-conductor openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler
