Openstack-glance鏡像服務

Openstack-glance鏡像服務

教程大綱

      

1. glance的服務組件介紹
2. glance的安裝部署

3. 上傳鏡像測試

1.建立glance的數據庫

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.安裝glance的組件

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/p_w_picpaths

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數據庫

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

6.啓動glance服務 

 

systemctl enable openstack-glance-api.service \

   openstack-glance-registry.service

   systemctl start openstack-glance-api.service \

   openstack-glance-registry.service

7.建立glance用戶

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

 將glance 加入服務中

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

8.註冊glance 的服務（若是想用glance 必須在keystone上作註冊）   

 

openstack service create --name glance \

  --description "OpenStack Image" p_w_picpath

9.建立glance服務

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

10.建立glance的三個端點

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

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

     

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

11.上傳鏡像測試

（若是沒有鏡像就能夠 wget http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img）

建立系統鏡像的glance命令

      openstack p_w_picpath create "cirros" \

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

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

     --public

查看鏡像的存放目錄

    ls ／var/lib／glance／p_w_picpaths／

13.驗證glance 的節點

glance  p_w_picpath-list
