Keystone服务详解

一、Keystone服务概述

在Openstack框架中，keystone(Openstack Identity Service)的功能是负责验证身份、校验服务规则和发布服务令牌的，它实现了Openstack的Identity API.keystone可分解为两个功能：权限管理和服务目录。

二、Keystone运维操作

1、keystone运维命令

# 环境配置
source /etc/keystone/admin-openrc.sh
# 创建 hqs用户
openstack user create --password ps1234 --email hqs@example.com --domain demo hqs
# 创建acme项目
openstack project create --domain demo acme
# 创建角色
openstack role create compute-user
# 绑定用户和项目权限
# 添加的用户需要分配一定的权限，需要把用户关联绑定到对应的项目和角色
openstack role add --user hqs --project acme compute-user

2、keystone查询命令

# 用户列表查询
[root@controller ~]# openstack user list
