这篇文章主要讲解了“OpenStack手动分布式部署Keystone的方法是什么”,文中的讲解内容简单清晰,易于学习与理解,下面请大家跟着小编的思路慢慢深入,一起来研究和学习“OpenStack手动分布式部署Keystone的方法是什么”吧!
Keystone(OpenStack Identity Service)是 OpenStack 框架中负责管理身份验证、服务访问规则和服务令牌功能的组件。用户访问资源需要验证用户的身份与权限,服务执行操作也需要进行权限检测,这些都需要通过 Keystone 来处理。Keystone 类似一个服务总线, 或者说是整个 Openstack 框架的注册表,OpenStack 服务通过 Keystone 来注册其 Endpoint(服务访问的URL),任何服务之间的相互调用,都需要先经过 Keystone 的身份验证,获得目标服务的 Endpoint ,然后再调用。
Keystone 的主要功能如下:
管理用户及其权限;
维护 OpenStack 服务的 Endpoint;
Authentication(认证)和 Authorization(鉴权)。
用户认证介绍
在用户认证中,有以下名词:
1、User(用户)
在Openstack中,使用一个数字来代表使用Openstack的人、系统或者是一个服务,Openstack会对用户的请求进行验证。在Openstack中,一个租户可以有多个用户、一个用户也可以有多个租户,用户对租户的操作权限由用户在租户中承担的角色来确定。
2、Project(项目)
Project是Openstack中一些可被访问的资源或者是资源组,本质上是一个容器,可以起到隔离的作用,或者用于标识对象。
3、Token(令牌)
Openstack中的用户用来进行身份验证的凭证。
4、Role(角色)
在Openstack中,Role代表一组权限,并且总是和用户所绑定,用于声明用户可以访问的资源。
服务目录介绍
在服务目录中,有以下名词:
1、Service(服务)
Service就是Openstack中的服务,比如Nova、Glance、Swift等等。
2、Endpoints(端点)
一个Endpoints即一个服务所对外暴露的接口,如果我们要访问一个服务,那么我们必须知道该服务的Endpoints。Endpoint的每个URL都对应一个服务实例访问地址,并且具有public、private和admin三种权限。public url可以被公开访问,private url可以被局域网内的设备所访问,而admin url则被从常规的访问中分离。
Keystone(OpenStack Identity Service)是 OpenStack 框架中负责管理身份验证、服务访问规则和服务令牌功能的组件。
下面我们进行Keystone的安装部署
[root@controller ~]# mysql -p Enter password: Welcome to the MariaDB monitor. Commands end with ; or \\g. Your MariaDB connection id is 18 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)]>
MariaDB [(none)]> CREATE DATABASE keystone;
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY '000000'; GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY '000000';
MariaDB [(none)]> quit;
[root@controller ~]# yum install openstack-keystone httpd mod_wsgi -y
##我在这里安装openstack-keystone httpd mod_wsgi时报错
解决办法:执行下面命令后重新安装
yum install -y python2-qpid-proton-0.22.0-1.el7.x86_64
[root@controller ~]# cp /etc/keystone/keystone.conf{,.bak} [root@controller ~]# grep -Ev "^$|#" /etc/keystone/keystone.conf.bak > /etc/keystone/keystone.conf

su -s /bin/sh -c "keystone-manage db_sync" keystone
进数据库检查一下看keystone是否有表了,如下说明同步完成
