前言

在官网和很多的博客网站上找了很多的例文，没有一个是可以完全搭建成功的，坑很多，给初次接触Openstack的我带来了很大的困扰，下面记录一下本次的部署过程，此次安装教程经过多次的测试，完全通过！

Openstack概述

OpenStack是一个NASA美国国家航空航天局和Rackspace合作研发的，以Apache讲可证授权，并且是一个自由软件和开放源代码项目。

Open是开放，Stack 则是堆砌之意，合起来就是将众多的功能服务堆积起来的集合，让人们通过 Openstack 云计算项目，能够将诸如计算能力、存储、网络和软件等资源抽象成服务，以便让用户可以通过互联网远程来享用，付费的形式也变得因需而定，调整方便，拥有极强的虚拟可扩展性，是公共和私有云的建设与管理软件中的优秀开源项目。

Openstack作用

OpenStack是一个云平台管理的项目，它不是一个软件。这个项目由几个主要的组件组合起来完成一些具体的工作。

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（简称IaaS）资源的通用前端。

IAAS、PAAS、SAAS概述

1、IaaS（Infrastructure as a Service），基础设施即服务。

消费者通过 Internet 可以从完善的计算机基础设施获得服务。这类服务称为基础设施即服务。基于 Internet 的服务（如存储和数据库）是 IaaS的一部分。比如：在腾讯云上买一台于主机（8个CPU，32G，5T硬盘于主机等）

2、PaaS是Platform-as-a-Service的缩写，开发平台即服务。把服务器平台作为一种服务提供的商业模式。

3、SaaS是Software-as-a-Service的缩写，软件即服务。

显而易见，现在最新的版本是Queens，而Rocky预计会在2018-08-30发布

Openstack各组件关系

1、Openstack核心组件主要有

Keystone（身份认证）
Nova（计算）
Neutron（网络）
Glance（镜像存储）
Cinder（块存储）
Swift（对象存储）
Horizon（web UI 界面）
Ceilometer（计量）
Heat（部署编排）
Trove（数据库）

Keystone（身份认证）:

统一的授权、认证管理。所有组件都依赖于 Keystone提供 3A(Account, Authentication, Authorization)服务。

3A认证：

1、认证(Authentication)，验证用户的身份不可使用的网络服务； 
2、授权(Authorization)：依据认证结果开放网络服务给用户； 
3、计帐(Accounting)：记录用户对各种网络服务的用量，并提供给计费系统。整个系统在网络管理与安全问题中十分有效。

比如：宽带收费就是3A认证的典型例子：输入帐号密码（认证）=> 开10M带宽（授权）=> 在营业厅（计帐）

Nova（计算）：

Nova是OpenStack 云中的计算组织控制器。Nova自身并没有提供任何虚拟化能力，相反它使用libvirt API 来与被支持的虚拟技术Hypervisors交互。如：kvm、Xen、VMware 等虚拟化技术。

Neutron（网络）：

实现虚拟机的网络资源管理如网络连接、ip管理、公网映射

Glance（镜像存储）：

主要存储和管理系统镜像。

Cinder（块存储）：

为虚拟机提供存储空间。比如硬盘，分区，目前支持ip-san、fc-san等。

Swift（对象存储）：

OpenStack Swift 开源项目提供了弹性可伸缩、高可用的分布式对象存储服务，适合存储大规模非结构化数据。通过key/value的方式实现对文件的存储，现在的云盘就是这样的，和 MFS， HDFS类似。注：如果客户需要一个1000T的存储空间，使用Cinder或Glance就不行，效率太低。这时就用Swift。

** Horizon（web UI 界面）：**

安装好后，openstack的web界面控制台DashBoard

Ceilometer（计量）：

Ceilometer是OpenStack中的一个子项目，它像一个漏斗一样，能把 OpenStack内部发生的几乎所有的事件都收集起来，然后为计费和监控以及其它服务提供数据支撑。

Heat（部署编排）：

是一个编排引擎，它可以基于文本文件形式的模板启动多个复合云应用程序（这些文件可以被视为代码）。简单来说，Heat为OpenStack 用户提供了一种自动创建云组件（如网络、实例、存储设备等）的方法。

Trove（数据库）：

为关系型数据库和非关系型数据库引擎提供可扩展的和可靠的云数据库服务，并继续改进其功能齐全、可扩展的开源框架。

Openstack-Queens详细安装教程

一、实验环境

         操作系统                      IP地址         内存      内核          主机名
Centos7.4 minimal 64位系统         192.168.1.92        6G      4核          node1
Centos7.4 minimal 64位系统         192.168.1.94        6G      4核          node2

二、增加域名解析（控制和计算节点）

vim /etc/hosts
192.168.1.92    node1
192.168.1.94    node2

scp /etc/hosts 192.168.1.94:/etc/hosts

三、关闭firewalld和selinux（控制和计算节点）

systemctl stop firewalld
systemctl disable firewalld
vim /etc/sysconfig/selinux
SELINUX=disabled

最好是reboot一次才生效

四、准备yum源（控制和计算节点）

如果是使用系统默认的yum源，是无法安装openstack的，这里需要修改一些参数，在本文中教大家怎么制作一个openstack的本地yum源，然后往后就直接本地安装openstack就行了，不需要联网才能安装

1、修改yum源

cd /etc/yum.repos.d/
mv * /opt/
mv /opt/CentOS-Base.repo /etc/yum.repos.d/
vim CentOS-Base.repo

[base]
name=CentOS-$releasever - Base
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra
#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
baseurl=http://vault.centos.org/7.4.1708/os/x86_64/

gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-$releasever - Plus
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus&infra=$infra
#baseurl=http://mirror.centos.org/centos/$releasever/centosplus/$basearch/
baseurl=http://vault.centos.org/7.4.1708/centosplus/x86_64/
gpgcheck=0
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

2、修改yum配置文件

vim /etc/yum.conf
keepcache=1

五、安装chrony服务

1、控制节点安装

yum clean all
yum -y install chrony

vim /etc/chrony.conf（添加）
server node1 iburst
allow 192.168.0.0./24

systemctl start chronyd
systemctl enable chronyd

2、计算节点安装

yum clean all
yum -y install chrony

vim /etc/chrony.conf（添加）
server node1 iburst

systemctl start chronyd
systemctl enable chronyd

六、安装openstack客户端（控制和计算节点）

yum -y install centos-release-openstack-queens

1、修改yum源（否则无法继续下一步安装，会报错）

vim /etc/yum.repos.d/CentOS-Ceph-Luminous.repo（修改红色部分）

[centos-ceph-luminous]
name=CentOS-$releasever - Ceph Luminous
#baseurl=http://mirror.centos.org/centos/$releasever/storage/$basearch/ceph-luminous/
baseurl=http://vault.centos.org/7.4.1708/storage/x86_64/ceph-luminous/
gpgcheck=0
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-Storage

vim /etc/yum.repos.d/CentOS-OpenStack-queens.repo（修改红色部分）

[centos-openstack-queens]
name=CentOS-7 - OpenStack queens
#baseurl=http://mirror.centos.org/centos/7/cloud/$basearch/openstack-queens/
baseurl=http://vault.centos.org/7.4.1708/cloud/x86_64/openstack-queens/
gpgcheck=0

2、安装openstack客户端

yum -y install python-openstackclient

3、安装openstack-selinux

yum -y install openstack-selinux

七、安装数据库（控制节点）

yum -y install mariadb mariadb-server python2-PyMySQL

1、创建并编辑配置文件

vim /etc/my.cnf.d/openstack.cnf
[mysqld]
bind-address = 192.168.1.92

default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8

2、启动并开机自启

systemctl start mariadb
systemctl enable mariadb

3、为数据库设置密码（我设置的123456）

mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we‘ll need the current
password for the root user.  If you‘ve just installed MariaDB, and
you haven‘t set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):       #直接回车
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] y
New password:               #设置密码123456
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success!


By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] y
 ... Success!

Normally, root should only be allowed to connect from ‘localhost‘.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] y
 ... Success!

By default, MariaDB comes with a database named ‘test‘ that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y
 ... Success!

Cleaning up...

All done!  If you‘ve completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

八、安装消息队列（控制节点）

yum -y install rabbitmq-server

1、启动并开机自启

systemctl start rabbitmq-server
systemctl enable rabbitmq-server

2、创建用户和密码

3、授权

rabbitmqctl set_permissions -p / openstack ‘.*‘ ‘.*‘ ‘.*‘
Setting permissions for user "openstack" in vhost "/" ...

4、设置角色

rabbitmqctl set_user_tags openstack administrator
Setting tags for user "openstack" to [administrator] ...

5、启用web插件

rabbitmq-plugins enable rabbitmq_management
The following plugins have been enabled:
  mochiweb
  webmachine
  rabbitmq_web_dispatch
  amqp_client
  rabbitmq_management_agent
  rabbitmq_management

Applying plugin configuration to rabbit@node1... started 6 plugins.

+-----------+----------------------------------+

7）把demo用户添加到user角色

openstack role add --project demo --user demo user

11、验证

1）解除环境变量的设置

unset OS_AUTH_URL OS_PASSWORD

2）使用admin用户请求token（这里需要输入admin用户的密码，我刚刚设置的是123456）

openstack --os-auth-url http://node1:35357/v3 --os-project-domain-name Default --os-user-domain-name Default --os-project-name admin --os-username admin token issue

技术分享图片

3）使用demo用户请求token（这里需要输入demo用户的密码，我刚刚设置的是123456）

openstack --os-auth-url http://node1:35357/v3 --os-project-domain-name Default --os-user-domain-name Default --os-project-name demo --os-username demo token issue

技术分享图片

12、创建环境变量脚本

1）创建admin用户的环境变量脚本

vim admin-openrc
export OS_PROJECT_DOMAIN_NAME=Default
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=123456
export OS_AUTH_URL=http://node1:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2

2）创建demo用户的环境变量脚本

export OS_PROJECT_DOMAIN_NAME=Default
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_NAME=demo
export OS_USERNAME=demo
export OS_PASSWORD=123456
export OS_AUTH_URL=http://node1:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2

3）验证脚本的效果

. admin-openrc
openstack token issue

技术分享图片

. demo-openrc
openstack token issue

十二、安装glance镜像服务（控制节点）

1、创建并设置glance的数据库

mysql -u root -p123456

MariaDB [(none)]> CREATE DATABASE glance;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO ‘glance‘@‘localhost‘ IDENTIFIED BY ‘123456‘;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO ‘glance‘@‘%‘ IDENTIFIED BY ‘123456‘;

2、创建glance镜像服务的keystone相关认证信息

1）设置admin用户的环境变量

. admin-openrc

2）创建glance用户（密码我设置的123456）

openstack user create --domain default --password-prompt glance
User Password:
Repeat User Password:
+---------------------+----------------------------------+
| Field               | Value                            |
+---------------------+----------------------------------+
| domain_id           | default                          |
| enabled             | True                             |

十六、安装neutron网络服务（控制节点）

1、创建并设置neutron的数据库

mysql -u root -p123456

MariaDB [(none)]> CREATE DATABASE neutron;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO ‘neutron‘@‘localhost‘ IDENTIFIED BY ‘123456‘;
MariaDB [(none)]>GRANT ALL PRIVILEGES ON neutron.* TO ‘neutron‘@‘%‘ IDENTIFIED BY ‘123456‘;

2、创建neutron网络服务的keystone相关认证信息

1）设置admin用户的环境变量

. admin-openrc

2）创建neutron用户（密码我设置的123456）

openstack user create --domain default --password-prompt neutron
User Password:
Repeat User Password:
+---------------------+----------------------------------+
| Field               | Value                            |
+---------------------+----------------------------------+
| domain_id           | default                          |
| enabled             | True                             |
| id                  | 01832b87e7e44c21941e5e5292f83c69 |
| name                | neutron                          |
| options             | {}                               |
| password_expires_at | None                             |
+---------------------+----------------------------------+

3）将neutron用户加入service项目，并设置为amdin角色

openstack role add --project service --user neutron admin

4）创建名为neutron的服务

openstack service create --name neutron --description "OpenStack Networking" network
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+

+--------------+----------------------------------+

3、安装neutron服务（采用self-service network的方式部署网络）

yum -y install openstack-neutron openstack-neutron-ml2 openstack-neutron-linuxbridge ebtables

4、修改配置文件

vim /etc/neutron/neutron.conf

……
[database]
connection = mysql+pymysql://neutron:123456@node1/neutron
……
[DEFAULT]
core_plugin = ml2
service_plugins = router
allow_overlapping_ips = true
transport_url = rabbit://openstack:openstack@node1
auth_strategy = keystone
notify_nova_on_port_status_changes = true
notify_nova_on_port_data_changes = true
……
[keystone_authtoken]
auth_uri = http://node1:5000
auth_url = http://node1:35357
memcached_servers = node1:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = neutron
password = 123456
……

创建安装openstack-queens的本地yum源

1、控制节点

yum -y install createrepo
mkdir -p /mnt/openstack-queens-packages
cd /var/cache/yum/x86_64/7/
find ./* -name "*.rpm"  -exec cp {} /mnt/openstack-queens-packages/ \;

2、计算节点

mkdir -p /mnt/openstack-queens-packages

find ./* -name "*.rpm"  -exec cp {} /mnt/openstack-queens-packages/ \;
scp /mnt/openstack-queens-packages/* 192.168.1.92:/mnt/

3、到控制节点上把所有的rpm包都放到一起

cd /mnt/
mv -f *.rpm openstack-queens-packages/

4、创建yum源

cd /mnt/openstack-queens-packages/
createrepo ./
ls repodata/

3886991bc70f1cfd55c6ae93848dc2c742faa87235cb046c4ba5f0a904621175-other.xml.gz
5b30f7b1336e7263a472f8dcf35ea0291c7b44cbceb900aefd167871b1a79895-primary.xml.gz
79dc4f64e75b04469b8b3cf73d9d8d868488a8812c298842fa29d5d17d45a68d-filelists.sqlite.bz2
b09465d254b0b50e8219b2de1378fddc13e49955293a6fe053a1df22562942fc-other.sqlite.bz2
d345ae675f39814467b495667ce575a5ce70062dfdbf74a78e2a2d6038fa2ca9-filelists.xml.gz
d3f1e0ba5f26e675d01c8dc713d25dfe7773d73f8a1401af1dadfae4f3c7c742-primary.sqlite.bz2
repomd.xml

5、打包

cd /mnt/
tar -zcvf openstack-queens-packages.tar.gz openstack-queens-packages/

6、把tar.gz包下载到本地保存起来，下次装openstack就可以不用联网安装了

7、接下来说一说怎么使用本地yum源安装openstack

1）把tar.gz包上传到服务器/root/openstack-queens-packages.tar.gz的目录下

2）解压

tar -zxvf openstack-queens-packages.tar.gz

3）配置yum源

cd /etc/yum.repos.d/
mv CentOS-* /opt/
vim openstack-queens.repo

[openstack-queens-packages]
name=openstack-queens-packages
baseurl=file:///root/openstack-queens-packages
gpgcheck=0
enable=1

4）接下来就可以尽情的安装openstack而不用联网下载了
