Openstack-glance镜像服务

教程大纲

1. glance的服务组件介绍
2. glance的安装部署

3. 上传镜像测试

1.创建glance的数据库

mysql -u root -p -e "create database glance;"

mysql -u root -p -e "grant all privileges on glance.* to ‘glance‘@‘localhost‘ identified by ‘glance‘;"

mysql -u root -p -e "grant all privileges on glance.* to ‘glance‘@‘%‘ identified by ‘glance‘;"

2.安装glance的组件

yum install openstack-glance

3.修改 glance-api的配置

verbose = true

connection = mysql://glance:glance@192.168.100.40/glance

stores = file,http

default_store = file

filesystem_store_datadir = /var/lib/glance/images

auth_uri = http://192.168.100.40:5000

auth_url = http://192.168.100.40:35357

auth_type = password

project_domain_name = default

user_domain_name = default

project_name = service

username = glance

password = glance

flavor = keystone

4.修改 glance-registry.conf

connection = mysql://glance:glance@192.168.100.40/glance

auth_uri = http://192.168.100.40:5000

auth_url = http://192.168.100.40:35357

auth_type = password

project_domain_name = default

user_domain_name = default

project_name = service

username = glance

password = glance

flavor = keystone

5.同步glance数据库

su -s /bin/sh -c "glance-manage db_sync" glance

6.启动glance服务 

systemctl enable openstack-glance-api.service \

   openstack-glance-registry.service

   systemctl start openstack-glance-api.service \

   openstack-glance-registry.service

7.创建glance用户

 openstack user create --domain default --password-prompt glance

 将glance 加入服务中

 openstack role add --project service --user glance admin

8.注册glance 的服务（如果想用glance 必须在keystone上做注册）   

openstack service create --name glance \

  --description "OpenStack Image" image

9.创建glance服务

openstack service create --name glance --description "OpenStack Image service" image

10.创建glance的三个端点

openstack endpoint create --region RegionOne image public http://192.168.100.40:9292

    openstack endpoint create --region RegionOne image internal http://192.168.100.40:9292

    openstack endpoint create --region RegionOne image admin http://192.168.100.40:9292

11.上传镜像测试

（如果没有镜像就可以 wget http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img）

创建系统镜像的glance命令

      openstack image create "cirros" \

     --file cirros-0.3.4-x86_64-disk.img \

     --disk-format qcow2 --container-format bare \

     --public

查看镜像的存放目录

    ls ／var/lib／glance／images／

13.验证glance 的节点
