Image Service 镜像服务代号Glance为云平台虚拟机提供镜像服务例如上传镜像、删除镜像等。说明镜像磁盘文件。装好了系统的磁盘文件。把镜像拷贝过来就不需要装系统。
1、登录数据库授权
1.Use the database access client to connect to the database server as the root user登录数据库
[rootcontroller ~]# mysql -p
Enter password:
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 31
Server version: 10.3.20-MariaDB MariaDB ServerCopyright (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)] 2.Create the glance database数据库里创建glance
MariaDB [(none)] CREATE DATABASE glance;
3.Grant proper access to the glance database:
MariaDB [(none)] GRANT ALL PRIVILEGES ON glance.* TO glance% \
IDENTIFIED BY 123;
4.退出数据库
MariaDB [(none)] quit
5.Create the glance user(创建glance用户密码为glance)
[rootcontroller ~]# openstack user create --domain default --password glance glance
Missing value auth-url required for auth plugin password如上我的这里会报错时因为没有source环境变量导致。
如下修改/etc/profile文件解决
#[rootcontroller ~]# vi /etc/profileexport OS_USERNAMEadmin
export OS_PASSWORD123
export OS_PROJECT_NAMEadmin
export OS_USER_DOMAIN_NAMEDefault
export OS_PROJECT_DOMAIN_NAMEDefault
export OS_AUTH_URLhttp://controller:5000/v3
export OS_IDENTITY_API_VERSION3[rootcontroller ~]# source /etc/profile
[rootcontroller ~]# openstack user create --domain default --password glance glance

-------------------------------------------------------6.Add the admin role to the glance user and service project增加admin角色
[rootcontroller ~]# openstack role add --project service --user glance admin7.Create the glance service entity创建glance服务
[rootcontroller ~]# openstack service create --name glance \--description OpenStack Image image

------------------------------------------------2、安装glance
1.安装glance包
[rootcontroller ~]# yum install openstack-glance -y2.备份配置文件并且修改修改了4个地方
[rootcontroller ~]# cp /etc/glance/glance-api.conf{,.bak}
[rootcontroller ~]# grep -Ev ^$|# /etc/glance/glance-api.conf.bak /etc/glance/glance-api.conf
[rootcontroller ~]# vi /etc/glance/glance-api.conf

3.同步数据库
[rootcontroller ~]# su -s /bin/sh -c glance-manage db_sync glance
[rootcontroller ~]# systemctl start openstack-glance-api.service
[rootcontroller ~]# systemctl enable openstack-glance-api.service4.这一步可以不做现在glance没有日志我们需要配置下
#[rootcontroller ~]# vi /etc/glance/glance-api.conf[DEFAULT]
log_file /var/log/glance/glance-api.log
[rootcontroller ~]# systemctl restart openstack-glance-api.service
[rootcontroller ~]# tail -f /var/log/glance/glance-api.log
). Its value may be silently ignored in the future.

下载cirros-0.4.0-x86_64-disk.img这个镜像上传到/opt下面镜像文件在我的资源csdn下载地方找到
切换到/opt目录下
[rootcontroller opt]# ls
cirros-0.4.0-x86_64-disk.img

以上说明部署glance成功
【glance镜像服务】
它在open stack中的项目名称为Glance.在早期的open stack版本中Glance只有管理镜像的功能并不具备镜像存储功能。现在Glance已经发展称为集上传检索管理和存储等多种功能的open stack核心服务。
【glance由两部分组成】
1glance-api 接受云系统镜像的创建删除读取请求
2glance-Registry 云系统的镜像注册服务
glance-api 是接受 rest api请求的。完成诸如镜像的查找获取上传删除等操作默认是监听9292端口glance-registry 是用于Mysql的数据交互用户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的各种数据。glance-Registry监听的端口是9191.Glance数据库中有两种表一张是image表主要存储了镜像格式大小等信息另一张是image property表主要存了镜像定制化信息。image-store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还有诸如cephsheepdogGluasterFS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。
【镜像服务的主要功能】
1.查询和获取镜像的元数据和镜像本身2.注册和上传虚拟机镜像包括镜像的创建、上传、下载和管理3.维护镜像信息包括元数据和镜像本身4.支持多种方式存储镜像包括普通的文件系统、swift、Amazon、S3等5.对虚拟机实例执行创建快照命令来创建新的镜像或者备份虚拟机的状态OpenStack简介 | 常见的基础组件 OpenStack云平台搭建(1) | 基础环境准备 OpenStack云平台搭建(2) | 安装Keystone
