Openstack 实战讲解之-----------04-控制节点glance服务安装配置

一、Glance介绍： 1.1 glance主要是由三部分组成： glance-api：接收云系统镜像的创建，删除，读取请求，类似nova-api，通过其他模块（glance-registry及image store）来完成诸如镜像的查找、获取、上传、删除等操作，api监听端口9292。 glance-registry：云系统的镜像注册服务，用于与mysql数据库交互，存储或获取镜像的元数据（metadata）；提供镜像元数据相关的REST接口，通过glance-registry，可以向数据库中写入或获取镜像各种数据，glance-registry监听端口9191，glance数据库中有两张表，一张是image表，另一张是image property表。image表保存了镜像格式、大小等信息；image property表则主要保存镜像的定制化信息。 imagestore：是一个存储的接口层，通过这个接口，glance可以获取镜像，image store支持的存储有Amazon的S3、Openstack本身的Swift还有注入ceph，sheepdog，GFS等分布式存储。image store是镜像保存与获取的接口，它仅仅是一个接口层，具体的实现需要外部的存储支持 二、Glance配置 2.1 项目以及端点配置 2.1.1 创建glance镜像服务 1 2 3 4 5 6 7 8 9 10 [root@linux-node1~] #openstackservicecreate--nameglance--description"OpenStackImage"image
