这篇文章主要介绍了Linux系统如何安装OpenStack，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。
的云计算管理平台项目，是一系列开源的。为私有云和公有云提供可扩展的弹性的。
OpenStack 是当今最具影响力的管理工具——通过命令或者基于 Web 的可视化控制面板来管理 IaaS 云端的资源池（服务器、存储和网络）。
它最先由美国国家航空航天局（NASA）和 Rackspace 在 2010 年合作研发，现在参与的人员和组织汇集了来自 100 多个国家的超过 9500 名的个人和 850 多个世界上赫赫有名的企业，如 NASA、谷歌、惠普、Intel、IBM、微软等。
1、selinux和firewalld状态为disabled
2、各主机信息如下：
| 主机 | ip |
|---|---|
| server1（控制节点—controller）。内存至少2G | 172.25.83.1 |
| server2（计算节点—compute）。内存至少2G | 172.25.83.1 |
3、可以将openstack的帮助文档，全部下载到本地，然后放到httpd服务的默认发布目录下，进行查看。

【1】、添加一块网卡：
[root@server1 ~]# ip a #两块网卡(eth0和eth2)
1: lo:mtu 65536 qdisc noqueue state UNKNOWN qlen 1
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: eth0:mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 52:54:00:fb:25:1b brd ff:ff:ff:ff:ff:ff
inet 172.25.83.1/24 brd 172.25.83.255 scope global eth0
valid_lft forever preferred_lft forever
inet6 fe80::5054:ff:fefb:251b/64 scope link
valid_lft forever preferred_lft forever
3: eth2:mtu 1500 qdisc noop state DOWN qlen 1000
link/ether 52:54:00:28:4a:31 brd ff:ff:ff:ff:ff:ff【2】、将第一个接口配置为管理网络接口：
[root@server1 ~]# cd /etc/sysconfig/network-scripts/
[root@server1 network-scripts]# vim ifcfg-eth0
1 BOOTPROTO=none
2 NAME=eth0
3 DEVICE=eth0
4 ONBOOT=yes
5 IPADDR=172.25.83.1
6 NETMASK=255.255.255.0
7 GATEWAY=172.25.83.83
8 DNS1=114.114.114.114【3】、提供者网络接口使用一个特殊的配置，不分配给它IP地址。并进行激活
[root@server1 network-scripts]# cp ifcfg-eth0 ifcfg-eth2
[root@server1 network-scripts]# vim ifcfg-eth2
1 BOOTPROTO=none
2 DEVICE=eth2
3 ONBOOT=yes
[root@server1 network-scripts]# ifup eth2 #激活eth2网卡
[root@server1 network-scripts]# ip addr show eth2
3: eth2:mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 52:54:00:28:4a:31 brd ff:ff:ff:ff:ff:ff
inet6 fe80::5054:ff:fe28:4a31/64 scope link
valid_lft forever preferred_lft forever【1】、设置节点主机名为 controller。
[root@server1 ~]# hostnamectl set-hostname controller
[root@server1 ~]# logout
Connection to 172.25.83.1 closed.
[student@foundation83 ~]$ ssh root@172.25.83.1
root@172.25.83.1's password:
[root@controller ~]# hostname
controller【2】、编辑 /etc/hosts 文件包含以下内容：
[root@controller ~]# vim /etc/hosts
172.25.83.1 controller
172.25.83.2 compute1
172.25.83.3 block1我这里配置虚拟机server1和server2同步我的物理机
#配置物理机,允许其他主机同步该物理机的时间
[root@foundation83 ~]# vim /etc/chrony.conf #将第22行修改为如下的内容,允许172.25网段的主机同步该主机
22 allow 172.25/16
[root@foundation83 ~]# systemctl restart chronyd.service #修改万配置文件之后,重启chronyd服务
[root@foundation83 ~]# systemctl enable chronyd.service #设置chronyd服务开机自启【1】、安装软件包：
[root@controller ~]# yum install chrony -y【2】、编辑 /etc/chrony.conf 文件：
[root@controller ~]# vim /etc/chrony.conf #删除第4行,第5行,第6行;并将第3行改为如下的内容
3 server 172.25.83.83 iburst【3】、启动chronyd服务并将其配置为随系统启动：
[root@controller ~]# systemctl restart chronyd
[root@controller ~]# chronyc sources -v #查看是否同步成功
210 Number of sources = 1
.-- Source mode '^' = server, '=' = peer, '#' = local clock.

[root@controller ~]# vim /etc/httpd/conf/httpd.conf #在第96行添加如下的内容
96 ServerName controller【2】、创建文件 /etc/httpd/conf.d/wsgi-keystone.conf，并进行编辑
[root@controller ~]# vim /etc/httpd/conf.d/wsgi-keystone.conf
Listen 5000
Listen 35357
WSGIDaemonProcess keystone-public processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}

ErrorLogFormat "%{cu}t %M"
ErrorLog /var/log/httpd/keystone-error.log
CustomLog /var/log/httpd/keystone-access.log combined
Require all granted【1】、启动 Apache HTTP 服务并配置其随系统启动，并查看80端口，5000端口和35357端口是否已经打开
[root@controller ~]# systemctl enable httpd.service
[root@controller ~]# systemctl start httpd.service
[root@controller ~]# netstat -antulpe | grep 80
tcp6 0 0 :::80 :::* LISTEN 0 25943 2827/httpd
[root@controller ~]# netstat -antulpe | grep 5000
tcp6 0 0 :::5000 :::* LISTEN 0 25951 2827/httpd
[root@controller ~]# netstat -antulpe | grep 35357
tcp6 0 0 :::35357 :::* LISTEN 0 25955 2827/httpd【1】、配置认证令牌：
[root@controller ~]# export OS_TOKEN=ca34150208112479d7b3【2】、配置端点URL：
[root@controller ~]# export OS_URL=http://controller:35357/v3【3】、配置认证 API 版本：
[root@controller ~]# export OS_IDENTITY_API_VERSION=3【1】、在你的Openstack环境中，认证服务管理服务目录。服务使用这个目录来决定您的环境中可用的服务。
创建服务实体和身份认证服务：
[root@controller ~]# openstack service create \
> --name keystone --description "OpenStack Identity" identity
+-------------+----------------------------------+
| Field | Value |
+-------------+----------------------------------+
| description | OpenStack Identity |
| enabled | True |
| id | e0109484377e4886b385fdf8e9467f79 |
| name | keystone |
| type | identity |
+-------------+----------------------------------+【2】、身份认证服务管理了一个与您环境相关的 API 端点的目录。服务使用这个目录来决定如何与您环境中的其他服务进行通信。OpenStack使用三个API端点变种代表每种服务：admin，internal和public。默认情况下，管理API端点允许修改用户和 租户而公共和内部APIs不允许这些操作。在生产环境中，处于安全原因，变种为了服务不同类型的用户可能驻留在单独的网络上。对实例而言，公共API网络 为了让顾客管理他们自己的云在互联网上是可见的。管理API网络在管理云基础设施的组织中操作也是有所限制的。内部API网络可能会被限制在包含 OpenStack服务的主机上。此外，OpenStack支持可伸缩性的多区域。为了简单起见，本指南为所有端点变种和默认RegionOne 区域都使用管理网络。
创建认证服务的 API 端点：
[root@controller ~]# openstack endpoint create --region RegionOne \
> identity public http://controller:5000/v3
+--------------+----------------------------------+
| Field | Value |
+--------------+----------------------------------+
| enabled | True |

[root@controller ~]# openstack server list
+--------------------------------------+---------+--------+------------------------+
| ID | Name | Status | Networks |
+--------------------------------------+---------+--------+------------------------+
| 5d7c18d4-d9d4-4edf-a0b6-0503b31421db | server1 | ACTIVE | provider=172.25.83.101 |
+--------------------------------------+---------+--------+------------------------+【1】、获取你实例的 会话URL并从web浏览器访问它：
[root@controller ~]# openstack console url show server1
+-------+---------------------------------------------------------------------------------+
| Field | Value |
+-------+---------------------------------------------------------------------------------+
| type | novnc |
| url | http://controller:6080/vnc_auto.html?token=79076f9f-4af0-41e5-b122-f008ce471f88 |
+-------+---------------------------------------------------------------------------------+【2】、浏览器访问该url
在物理机的本地解析文件中添加controller的解析（这是因为要在物理机的浏览器中进行访问）
[root@foundation83 ~]# vim /etc/hosts
172.25.83.1 controller
从上图，我们可以看到该实例有问题。导致这个问题的原因在于centos7.3源中的qemu1.5版本低，更新一下qemu版本即可。解决方法如下：参见博客（https://blog.csdn.net/wjciayf/article/details/73741146）
