Centos7.3 部署openstack ocata详解
OpenStack企业私有云
一、openstack 介绍
OpenStack是一个由NASA（美国国家航空航天局）和Rackspace合作研发并发起的，以Apache许可证授权的自由软件和开放源代码项目。
OpenStack是一个开源的云计算管理平台项目，由几个主要的组件组合起来完成具体工作。OpenStack支持几乎所有类型的云环境，项目目标是提供实施简单、可大规模扩展、丰富、标准统一的云计算管理平台。OpenStack通过各种互补的服务提供了基础设施即服务（IaaS）的解决方案，每个服务提供API以进行集成。
OpenStack是一个旨在为公共及私有云的建设与管理提供软件的开源项目。它的社区拥有超过130家企业及1350位开发者，这些机构与个人都将OpenStack作为基础设施即服务（IaaS）资源的通用前端。OpenStack项目的首要任务是简化云的部署过程并为其带来良好的可扩展性。本文希望通过提供必要的指导信息，帮助大家利用OpenStack前端来设置及管理自己的公共云或私有云。
OpenStack云计算平台，帮助服务商和企业内部实现类似于 Amazon EC2 和 S3 的云基础架构服务(Infrastructure as a Service, IaaS)。OpenStack 包含两个主要模块：Nova 和 Swift，前者是 NASA 开发的虚拟服务器部署和业务计算模块；后者是 Rackspace开发的分布式云存储模块，两者可以一起用，也可以分开单独用。OpenStack除了有 Rackspace 和 NASA 的大力支持外，还有包括 Dell、Citrix、 Cisco、 Canonical等重量级公司的贡献和支持，发展速度非常快，有取代另一个业界领先开源云平台 Eucalyptus 的态势。

三、搭建openstack
3.1 安装keystone 组件介绍（node2 主控制节点操作）
Keystone功能：
- 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
Keystone名词： User： 用户 Tenant： 租户/项目 Token： 令牌 Role： 角色 Service： 服务 Endpoint： 端点
3.2 安装keystone 组件
安装openstack最新的源：
#yum install centos-release-openstack-ocata
#yum install https://rdoproject.org/repos/rdo-release.rpm
#yum upgrade (在主机上升级包）
#yum install python-openstackclient （安装opentack必须的插件）
#yum install openstack-selinux （可选则安装这个插件，我直接关闭了selinux，因为不熟，对后续不会有影响）
[root@linux-node1 home]# yum install openstack-keystone httpd mod_wsgi
3.2.1修改配置文件
vim /etc/keystone/keystone.conf
[database]
connection = mysql://keystone:keystone@192.168.57.141/keystone
[token]
provider=fernet
3.2.2同步数据库
su -s /bin/sh -c "keystone-manage db_sync" keystone
###为什么需要su 一下呢？因为在写日志的时候文件是放在/var/log/keystone 这个下面如果是root用户执行的话。那么写日志的时候就会写不进去。
验证一下是否成功。进入数据库查看有没有表的建立。
MariaDB [keystone]> show tables;
+------------------------+
| Tables_in_keystone |
初始化
# keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
# keystone-manage credential_setup --keystone-user keystone --keystone-group keystone
引导身份信息
keystone-manage bootstrap --bootstrap-password ADMIN_PASS \
--bootstrap-admin-url http://linux-node2:35357/v3/ \
--bootstrap-internal-url http://linux-node2:5000/v3/ \
--bootstrap-public-url http://controller:5000/v3/ \
--bootstrap-region-id RegionOne
3.2.3配置memcache的配置（/etc/sysconfig/memcached）
vim /etc/sysconfig/memcached
OPTIONS="-l 127.0.0.1,::1,192.168.57.141"
3.2.4启动memcache
[root@linux-node2 ~]# systemctl start memcached.service
[root@linux-node2 ~]# netstat -nltp|grep 121
tcp 0 0 0.0.0.0:11211 0.0.0.0:* LISTEN 20054/memcached
tcp6 0 0 :::11211 :::* LISTEN 20054/memcached
3.2.5设置apache
ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/
3.2.6修改主apache的主配置文件
vim /etc/httpd/conf/httpd.conf
配置一下Servername
ServerName 192.168.57.138:80
3.2.7启动apache
systemctl enable httpd.service
systemctl start httpd.service
3.2.8检查一下是否启动成功了
[root@linux-node2 conf.d]# netstat -nltp|grep httpd
tcp6 0 0 :::80 :::* LISTEN 20253/httpd
tcp6 0 0 :::35357 :::* LISTEN 20253/httpd
tcp6 0 0 :::5000 :::* LISTEN 20253/httpd
[root@linux-node2 conf.d]#
3.3 keystone 用户权限
3.3.1 设置环境变量
$exportOS_USERNAME=admin
$exportOS_PASSWORD=ADMIN_PASS
$exportOS_PROJECT_NAME=admin
$exportOS_USER_DOMAIN_NAME=Default
$exportOS_PROJECT_DOMAIN_NAME=Default
$exportOS_AUTH_URL=http://linux-node2:35357/v3
$exportOS_IDENTITY_API_VERSION=3
3.3.2创建域、项目、用户和角色
创建服务
[root@linux-node2 ~]# openstack project create --domain default --description "Service Project" service
创建demo项目
[root@linux-node2 ~]# openstack project create --domain default \
> --description "Demo Project" demo
设置demo密码
[root@linux-node2 ~]# openstack user create --domain default \
> --password-prompt demo
创建用户组
[root@linux-node2 ~]# openstack role create user
加入用户组
[root@linux-node2 ~]# openstack role add --project demo --user demo user
3.3.3验证操作
1. 出于安全原因，请禁用临时身份验证令牌机制：
编辑/etc/keystone/keystone-paste.ini 文件并删除admin_token_auth从 [pipeline:public_api]，[pipeline:admin_api]和[pipeline:api_v3]段。
2、取消设置临时 变量OS_AUTH_URL和OS_PASSWORD环境变量：
[root@linux-node2 ~]# unset OS_AUTH_URL OS_PASSWORD
3、作为admin 、请求身份验证令牌
$ openstack --os-auth-url http://linux-node2:35357/v3 \
--os-project-domain-name default --os-user-domain-name default \
--os-project-name admin --os-username admin token issue
Password:

七、网络节点一（node2 主配置节点操作）
7.1 设置mysql
$ mysql -u root –p
MariaDB [（none）] CREATE DATABASE neutron;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' \
IDENTIFIED BY 'neutron';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' \
IDENTIFIED BY 'neutron';
7.2创建服务凭据
在admin的环境下
$ . admin-openrc
$ openstack user create --domain default --password-prompt neutron
User Password: neutron #密码
Repeat User Password: neutron #密码
+---------------------+----------------------------------+
| Field | Value |
+---------------------+----------------------------------+
| domain_id | default |
| enabled | True |
| id | fdb0f541e28141719b6a43c8944bf1fb |
| name | neutron |
| options | {} |
| password_expires_at | None |
+---------------------+----------------------------------+
加入到admin组
$ openstack role add --project service --user neutron admin
创建neutron 服务实体
$ openstack service create --name neutron \
--description "OpenStack Networking" network
创建neutron API
$ openstack endpoint create --region RegionOne \
network public http://linux-node2:9696
$ openstack endpoint create --region RegionOne \
network internal http://linux-node2:9696
$ openstack endpoint create --region RegionOne \
network admin http://linux-node2:9696
7.3配置网络选项（这里我选用的是网络1 的配置）
您可以使用选项1和2所代表的两种体系结构之一来部署网络服务。
选项1部署了最简单的架构，只支持将实例连接到提供者（外部）网络。没有自助服务（专用）网络，路由器或浮动IP地址。只有admin或其他特权用户才能管理提供商网络。
选项2增加了选项1，其中第三层服务支持将实例附加到自助服务网络。这个demo或其他非特权用户可以管理自助服务网络，包括在自助服务和提供商网络之间提供连接的路由器。此外，浮动IP地址还提供与使用来自外部网络（如Internet）的自助服务网络的实例的连接。
自助服务网络通常使用覆盖网络。覆盖网络协议（如VXLAN）包含额外的标头，这些标头会增加开销并减少有效负载或用户数据的可用空间。在不了解虚拟网络基础架构的情况下，实例将尝试使用1500字节的默认以太网最大传输单元（MTU）发送数据包。网络服务通过DHCP自动为实例提供正确的MTU值。但是，某些云图像不使用DHCP或忽略DHCP MTU选项并需要使用元数据或脚本进行配置。
7.4 安装网络openstack-neutron
# yum install openstack-neutron openstack-neutron-ml2 \
openstack-neutron-linuxbridge ebtables
7.5 编辑/etc/neutron/neutron.conf

username = neutron
password = neutron ###在身份识别服务中为用户选择的密码。
service_metadata_proxy = true
metadata_proxy_shared_secret = neutron # #为元数据代理选择的密码。
创建扩展链接
# ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
7.10同步数据库
# su -s /bin/sh -c "neutron-db-manage --config-file /etc/neutron/neutron.conf \
--config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade head" neutron
