在控制节点
安装和配置
先决条件
在你配置 OpenStack 身份认证服务前，你必须创建一个数据库和管理员令牌。
完成下面的步骤以创建数据库：
用数据库连接客户端以 root 用户连接到数据库服务器：
bash
$ mysql -u root -p创建 keystone 数据库：
bash
CREATE DATABASE keystone;对keystone数据库授予恰当的权限：
bash
MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \
IDENTIFIED BY 'KEYSTONE_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \
IDENTIFIED BY 'KEYSTONE_DBPASS';
bash
[root@controller ~]# mysql -u root -p
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 8
Server version: 10.3.20-MariaDB MariaDB Server
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE DATABASE keystone;
Query OK, 1 row affected (0.009 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \
-> IDENTIFIED BY 'zmd_9001';
Query OK, 0 rows affected (0.001 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \
-> IDENTIFIED BY 'zmd_9001';
Query OK, 0 rows affected (0.001 sec)安装并配置组件
运行以下命令来安装包。
bash
# yum -y install openstack-keystone httpd mod_wsgi提前要关闭selinux和firewalld，否则后面有的服务没有相应
编辑文件 /etc/keystone/keystone.conf 并完成如下动作：
在 [database] 部分，配置数据库访问：
bash
[database]
# ...
connection = mysql+pymysql://keystone:KEYSTONE_DBPASS@controller/keystone将KEYSTONE_DBPASS替换为你为数据库选择的密码。
在[token]部分，配置Fernet UUID令牌的提供者。
bash
[token]
# ...
provider = fernet初始化身份认证服务的数据库：
bash
# su -s /bin/sh -c "keystone-manage db_sync" keystone注解
忽略输出中任何不推荐使用的信息。
初始化Fernet keys：
bash
keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
keystone-manage credential_setup --keystone-user keystone --keystone-group keystoneBootstrap the Identity service:
bash
# keystone-manage bootstrap --bootstrap-password ADMIN_PASS \
--bootstrap-admin-url http://controller:5000/v3/ \
--bootstrap-internal-url http://controller:5000/v3/ \
--bootstrap-public-url http://controller:5000/v3/ \
--bootstrap-region-id RegionOne配置 Apache HTTP 服务器
编辑/etc/httpd/conf/httpd.conf 文件，配置ServerName 选项为控制节点：
bash
ServerName controllerCreate a link to the /usr/share/keystone/wsgi-keystone.conf file:
bash
# ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/完成安装
启动 Apache HTTP 服务并配置其随系统启动：
bash
systemctl enable httpd.service
systemctl start httpd.service报错
bash

Configure the administrative account by setting the proper environmental variables:
bash
$ export OS_USERNAME=admin
$ export OS_PASSWORD=ADMIN_PASS
$ export OS_PROJECT_NAME=admin
$ export OS_USER_DOMAIN_NAME=Default
$ export OS_PROJECT_DOMAIN_NAME=Default
$ export OS_AUTH_URL=http://controller:5000/v3
$ export OS_IDENTITY_API_VERSION=3Create a domain, projects, users, and roles
The Identity service provides authentication services for each OpenStack service. The authentication service uses a combination of domains, projects, users, and roles.
认证服务为openstack服务提供认证服务，认证服务使用了域，项目，用户和角色的组合。
Although the "default" domain already exists from the keystone-manage bootstrap step in this guide, a formal way to create a new domain would be:
创建域
bash
$ openstack domain create --description "An Example Domain" example
+-------------+----------------------------------+
| Field | Value |
+-------------+----------------------------------+
| description | An Example Domain |
| enabled | True |
| id | 2f4f80574fd84fe6ba9067228ae0a50c |
| name | example |
| tags | [] |
+-------------+----------------------------------+报错
bash
[root@controller ~]# openstack domain create --description "An Example Domain" example
Missing value auth-url required for auth plugin password因为重启了系统，没有保存环境变量。
重新执行下上面的环境变量设置。

This guide uses a service project that contains a unique user for each service that you add to your environment. Create the service project:
bash
$ openstack project create --domain default \
--description "Service Project" service

| Field | Value |
+-------------+----------------------------------+

+-------------+----------------------------------+Regular (non-admin) tasks should use an unprivileged project and user. As an example, this guide creates the myproject project and myuser user.

+------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+创建 OpenStack 客户端环境脚本
前一节中使用环境变量和命令选项的组合通过openstack客户端与身份认证服务交互。为了提升客户端操作的效率，OpenStack支持简单的客户端环境变量脚本即OpenRC 文件。这些脚本通常包含客户端所有常见的选项，当然也支持独特的选项
创建脚本
创建 admin 和 demo项目和用户创建客户端环境变量脚本。本指南的接下来的部分会引用这些脚本，为客户端操作加载合适的的凭证
这个脚本可以放在任何一个安全和方便拿到的位置。
编辑文件 admin-openrc 并添加如下内容：
bash
export OS_PROJECT_DOMAIN_NAME=Default
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=ADMIN_PASS
export OS_AUTH_URL=http://controller:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2Replace ADMIN_PASS with the password you chose for the admin user in the Identity service.
Create and edit the demo-openrc file and add the following content:
bash
export OS_PROJECT_DOMAIN_NAME=Default
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_NAME=myproject
export OS_USERNAME=myuser
export OS_PASSWORD=DEMO_PASS
export OS_AUTH_URL=http://controller:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2Replace DEMO_PASS with the password you chose for the demo user in the Identity service.
使用脚本
使用特定租户和用户运行客户端，你可以在运行之前简单地加载相关客户端脚本。例如：
加载admin-openrc文件来身份认证服务的环境变量位置和admin项目和用户证书：
bash
$ . admin-openrc请求认证令牌:
bash
$ openstack token issue
