OpenStack项目主要提供:计算服务、存储服务、镜像服务、网络服务,均依赖于身份认证keystone的支撑。其中的每个项目可以拆开部署,同一项目也可以部署在多台=物理机上,并且每个服务都提供了应用接口程序(API),方便与第三方集成调用资源。

环境准备

安装openstack环境的硬件需求

socket=/var/lib/mysql/mysql.sock
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid
bind-address = 172.16.10.33   //修改为控制节点IP,使其他节点可以通过管理网络访问数据库
default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8

添加openstack用户

如果在添加用户时报错,就检查是否修改了主机名,或者是在之前的操作中修改主机名之后未重启,重启即可解决创建用户报错

rabbitmqctl add_user openstack 123456         //创建用户openstack,密码为123456
rabbitmqctl set_permissions openstack ".*" ".*" ".*"   //授予新建用户权限

开启服务并设置为开机自启

systemctl enable etcd.service
systemctl start etcd.service

部署keystone认证服务

Identity服务为其他OpenStack服务提供验证和授权服务,为所有服务提供终端目录,其他OpenStack服务将身份认证当作通用统一API来使用。此外,提供用户信息但是不在OpenStack项目中的服务(如LDAP服务)可被整合进先前存在的基础设施中。
为了从identify服务中获益,其他的OpenStack服务需要与他合作。当某个OpenStack服务需要与他合作。当某个OpenStack服务收到来自用户的请求时,该服务询问identify服务,验证该用户是否有权限进行此次请求,身份验证服务包括以下组件

  • 服务器:一个中心化的服务器使用RESTful接口来提供认证和授权服务
  • 驱动:驱动或服务后端被整合进集中式服务器中。它们被用来访问OpenStack外部仓库的身份信息,并且它们可能已经存在于OpenStack被部署在的基础设施中,如SQL数据库
  • 模块:中间件模块运行于使用身份验证服务的OpenStack组件的地址空间中。这些模块拦截服务请求,取出用户凭据,并将它们送入中央服务器寻求授权。中间件模块和OpenStack组件间的整合使用python web服务器网关接口。
    当安装OpenStack自身服务时,用户必须将之注册到其OpenStack安装环境的每个服务。身份服务才可以追踪到哪些OpenStack服务已经安装,以及在网络中定位它们。
