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。
OpenStack是一个开源的云计算管理平台项目，是一系列软件开源项目的组合。为私有云和公有云提供可扩展的弹性的云计算服务。
OpenStack 是当今最具影响力的云计算管理工具——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。

[root@controller ~]# su -s /bin/sh -c "keystone-manage db_sync" keystone [root@controller ~]# mysql -uroot -p Enter password: MariaDB [(none)]> use keystone; MariaDB [keystone]> show tables; +------------------------+ | Tables_in_keystone | +------------------------+ | access_token | | assignment | | config_register | | consumer | | credential | | domain | | endpoint | | endpoint_group | | federated_user | | federation_protocol | | group | | id_mapping | | identity_provider | | idp_remote_ids | | implied_role | | local_user | | mapping | | migrate_version | | password | | policy | | policy_association | | project | | project_endpoint | | project_endpoint_group | | region | | request_token | | revocation_event | | role | | sensitive_config | | service | | service_provider | | token | | trust | | trust_role | | user | | user_group_membership | | whitelisted_config | +------------------------+ 37 rows in set (0.00 sec) MariaDB [keystone]> ^DBye #按"Ctrl+d"退出数据库客户端【4】、初始化Fernet keys，并测试是否初始化成功
[root@controller ~]# keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone [root@controller ~]# cd /etc/keystone/ #该目录下生成了fernet-keys目录,表示初始化成功 [root@controller keystone]# ll total 100 -rw-r----- 1 root keystone 2303 Sep 22 2016 default_catalog.templates drwx------ 2 keystone keystone 24 Apr 18 19:50 fernet-keys -rw-r----- 1 root keystone 73221 Apr 18 19:42 keystone.conf -rw-r----- 1 root keystone 2400 Sep 22 2016 keystone-paste.ini -rw-r----- 1 root keystone 1046 Sep 22 2016 logging.conf -rw-r----- 1 keystone keystone 9699 Sep 22 2016 policy.JSON -rw-r----- 1 keystone keystone 665 Sep 22 2016 sso_callback_template.html【1】、编辑/etc/httpd/conf/httpd.conf 文件，配置ServerName 选项为控制节点：
[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} WSGIProcessGroup keystone-public WSGIScriptAlias / /usr/bin/keystone-wsgi-public WSGIApplicationGroup %{GLOBAL} WSGIPassAuthorization On ErrorLogFORMat "%{cu}t %M" ErrorLog /var/log/httpd/keystone-error.log CustomLog /var/log/httpd/keystone-access.log combined Require all granted WSGIDaemonProcess keystone-admin processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP} WSGIProcessGroup keystone-admin WSGIScriptAlias / /usr/bin/keystone-wsgi-admin WSGIApplicationGroup %{GLOBAL} WSGIPassAuthorization On 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 || id | b622d05e1cf14b9aa46ce0b67fc282d8 || interface | public || region | RegionOne || region_id | RegionOne || service_id | e0109484377e4886b385fdf8e9467f79 || service_name | keystone || service_type | identity || url | http://controller:5000/v3 |+--------------+----------------------------------+ [root@controller ~]# openstack endpoint create --region RegionOne \> identity internal http://controller:5000/v3+--------------+----------------------------------+| Field | Value |+--------------+----------------------------------+| enabled | True || id | fb5705a8143D4cc7a912c18df7f499c6 || interface | internal || region | RegionOne || region_id | RegionOne || service_id | e0109484377e4886b385fdf8e9467f79 || service_name | keystone || service_type | identity || url | http://controller:5000/v3 |+--------------+----------------------------------+ [root@controller ~]# openstack endpoint create --region RegionOne \> identity admin http://controller:35357/v3+--------------+----------------------------------+| Field | Value |+--------------+----------------------------------+| enabled | True || id | 1316fa22cd1b402dbb7795804878007f || interface | admin || region | RegionOne || region_id | RegionOne || service_id | e0109484377e4886b385fdf8e9467f79 || service_name | keystone || service_type | identity || url | http://controller:35357/v3 |+--------------+----------------------------------+查看服务实体，身份认证服务和API端点是否创建成功
