08-OpenStack-queens版-控制節(jié)點(diǎn)glance服務(wù)

glance架構(gòu)


image.png

1月杉、客戶端client
glance服務(wù)應(yīng)用程序的使用者:OpenStack命令行工具刃跛、horizon、Nova服務(wù)
2苛萎、glance-api：
glance入口奠伪，用于接收鏡像REST API的調(diào)用跌帐，諸如鏡像查找，獲取绊率，上傳，刪除
3究履、glance-registry：
用于與mysql數(shù)據(jù)庫交互滤否，監(jiān)聽端口為9191，
提供鏡像元數(shù)據(jù)相關(guān)的REST接口最仑，用于存儲藐俺、處理和恢復(fù)鏡像的元數(shù)據(jù)（metadata），元數(shù)據(jù)包括項(xiàng)諸如大小和類型泥彤。
通過glance-registry可以向數(shù)據(jù)庫中寫入或獲取鏡像的各種數(shù)據(jù)
其中有兩張表欲芹，image表保存了鏡像格式大小等信息，image property表保存進(jìn)行的定制化信息
注意：glance-registry是私有內(nèi)部服務(wù)吟吝，用于服務(wù)OpenStack Image服務(wù)菱父。不能向用戶暴露

OpenStack-queens版-控制節(jié)點(diǎn)部署glance服務(wù)
1、安裝配置glance之前先以root用戶身份使用數(shù)據(jù)庫訪問客戶端剑逃，連接到數(shù)據(jù)庫服務(wù)器
[root@controller ~]# mysql -u root -p
Enter password:
MariaDB [(none)]> CREATE DATABASE glance; #創(chuàng)建數(shù)據(jù)庫glance
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY 'whj1218' ; #對本地授權(quán)浙宜，密碼為whj1218
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY 'whj1218';#
MariaDB [(none)]> show databases;
+--------------------+
| Database |
+--------------------+
| glance |
| information_schema |
| keystone |
| mysql |
| performance_schema |
+--------------------+
MariaDB [(none)]> quit #退出數(shù)據(jù)庫

2、在keystone上面注冊glance
1）在keystone上創(chuàng)建glance用戶
[root@controller ~]# source keystone-admin-pass.sh #加載admin的環(huán)境變量
[root@controller ~]# openstack user create --domain default --password-prompt glance #創(chuàng)建glance用戶蛹磺，密碼為whj1218
User Password:
Repeat User Password:
+---------------------+----------------------------------+
| Field | Value |
+---------------------+----------------------------------+
| domain_id | default |
| enabled | True |
| id | b2f7c49185004822957e5e40227b833a |
| name | glance |
| options | {} |
| password_expires_at | None |
+---------------------+----------------------------------+
[root@controller ~]# openstack user list #列出用戶
+----------------------------------+---------+
| ID | Name |
+----------------------------------+---------+
| 4640a445474e44abba73328aa81a805b | admin |

| b2f7c49185004822957e5e40227b833a | glance |
+----------------------------------+---------+
[root@controller ~]# openstack role add --project service --user glance admin#在keystone上將glance用戶添加為service項(xiàng)目的admin角色(權(quán)限)
3）創(chuàng)建glance鏡像服務(wù)的實(shí)體
[root@controller ~]# openstack service create --name glance --description "OpenStack Image" image#創(chuàng)建glance服務(wù)條目粟瞬，在service表中增加glance項(xiàng)目
+-------------+----------------------------------+
| Field | Value |
+-------------+----------------------------------+
| description | OpenStack Image |
| enabled | True |
| id | 04289507c30f41faa7ba4e5f730db3d0 |
| name | glance |
| type | image |
+-------------+----------------------------------+
[root@controller ~]# openstack service list #列出服務(wù)
+----------------------------------+----------+----------+
| ID | Name | Type |
+----------------------------------+----------+----------+
| 04289507c30f41faa7ba4e5f730db3d0 | glance | image |
| 5bf0447c80e44bc5a68d8ccc554d81e8 | keystone | identity |
+----------------------------------+----------+----------+
4）創(chuàng)建鏡像服務(wù)的 API 端點(diǎn)（endpoint）
[root@controller ~]# openstack endpoint create --region RegionOne image internal http://controller:9292
+--------------+----------------------------------+
| Field | Value |
+--------------+----------------------------------+
| enabled | True |

| interface | internal |
| region | RegionOne |
| region_id | RegionOne |
| service_id | 04289507c30f41faa7ba4e5f730db3d0 |
| service_name | glance |
| service_type | image |
| url | http://controller:9292 |
+--------------+----------------------------------+
[root@controller ~]# openstack endpoint create --region RegionOne image public http://controller:9292

| service_name | glance |
| service_type | image |
| url | http://controller:9292 |
+--------------+----------------------------------+
[root@controller ~]# openstack endpoint list
+----------------------------------+-----------+--------------+--------------+---------+-----------+-----------------------------+
| ID | Region | Service Name | Service Type | Enabled | Interface | URL |
+----------------------------------+-----------+--------------+--------------+---------+-----------+-----------------------------+

+----------------------------------+-----------+--------------+--------------+---------+-----------+-----------------------------+

4.同步glance數(shù)據(jù)庫
1）為glance鏡像服務(wù)初始化同步數(shù)據(jù)庫
[root@controller ~]# su -s /bin/sh -c "glance-manage db_sync" glance #生成的相關(guān)表
2）同步完成進(jìn)行連接測試
[root@controller ~]# mysql -h192.168.136.134 -uglance -pwhj1218 -e "use glance;show tables;"# 保證所有需要的表已經(jīng)建立萤捆，否則后面可能無法進(jìn)行下去
+----------------------------------+
| Tables_in_glance |

[root@controller ~]# mysql -h192.168.136.134 -uglance -pwhj1218 -e "use glance;show tables;" |wc -l #統(tǒng)計(jì)生成的表有15張

5.啟動glance鏡像服務(wù)
1）啟動glance鏡像服務(wù)裙品、并配置開機(jī)自啟動
[root@controller ~]# systemctl start openstack-glance-api.service openstack-glance-registry.service #啟動服務(wù)
[root@controller ~]# systemctl enable openstack-glance-api.service openstack-glance-registry.service#設(shè)置開機(jī)自啟動
[root@controller ~]# systemctl status openstack-glance-api.service openstack-glance-registry.service#查看服務(wù)狀態(tài)
[root@controller ~]# systemctl list-unit-files |grep openstack-glance*
openstack-glance-api.service enabled
openstack-glance-registry.service enabled
openstack-glance-scrubber.service disabled
6.檢查確認(rèn)glance安裝正確
可以下載小型的Linux鏡像CirrOS用來進(jìn)行 OpenStack部署測試
[root@controller ~]# wget http://download.cirros-cloud.net/0.3.5/cirros-0.3.5-x86_64-disk.img #下載linux鏡像cirros
