本溪網(wǎng)站建設(shè),網(wǎng)站建站公司,做seo是要先有網(wǎng)站嗎,企業(yè)網(wǎng)站建設(shè)全套流程目錄 1、登錄數(shù)據(jù)庫(kù)授權(quán) 2、安裝glance 3、測(cè)試一下安裝部署Glance鏡像服務(wù) Image Service 鏡像服務(wù)：代號(hào)：Glance：為云平臺(tái)虛擬機(jī)提供鏡像服務(wù)，例如：上傳鏡像、刪除鏡像等。說明：鏡像：磁盤…

1、登錄數(shù)據(jù)庫(kù)授權(quán)

2、安裝glance

3、測(cè)試一下

安裝部署Glance鏡像服務(wù)

Image Service? 鏡像服務(wù)：
代號(hào)：Glance：
為云平臺(tái)虛擬機(jī)提供鏡像服務(wù)，例如：上傳鏡像、刪除鏡像等。
說明：鏡像：磁盤文件。裝好了系統(tǒng)的磁盤文件。把鏡像拷貝過來，就不需要裝系統(tǒng)。

1、登錄數(shù)據(jù)庫(kù)授權(quán)

1.Use the database access client to connect to the database server as the?root?user（登錄數(shù)據(jù)庫(kù)）

[root@controller ~]# 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（數(shù)據(jù)庫(kù)里創(chuàng)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.退出數(shù)據(jù)庫(kù)

MariaDB [(none)]> quit

5.Create the?glance?user(創(chuàng)建glance用戶密碼為glance)?

[root@controller ~]# openstack user create --domain default --password glance glance
Missing value auth-url required for auth plugin password

如上我的這里會(huì)報(bào)錯(cuò)，時(shí)因?yàn)闆]有source環(huán)境變量導(dǎo)致。

如下修改/etc/profile文件解決：

#[root@controller ~]# vi /etc/profileexport OS_USERNAME=admin
export OS_PASSWORD=123
export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_AUTH_URL=http://controller:5000/v3
export OS_IDENTITY_API_VERSION=3

[root@controller ~]# source /etc/profile
[root@controller ~]# openstack user create --domain default --password glance glance
+---------------------+----------------------------------+
| Field               | Value                            |
+---------------------+----------------------------------+
| domain_id           | default                          |
| enabled             | True                             |
| id                  | 0293557b8f094dd3855537343b14228b |
| name                | glance                           |
| options             | {}                               |
| password_expires_at | None                             |
+---------------------+----------------------------------+

6.Add the?admin?role to the?glance?user and?service?project（增加admin角色）

[root@controller ~]# openstack role add --project service --user glance admin

7.Create the?glance?service entity（創(chuàng)建glance服務(wù)）

[root@controller ~]# openstack service create --name glance \
>   --description "OpenStack Image" image
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | OpenStack Image                  |
| enabled     | True                             |
| id          | 906253e30699402a9f3a52405119532c |
| name        | glance                           |
| type        | image                            |
+-------------+----------------------------------+

8.Create the Image service API endpoints（創(chuàng)建API端點(diǎn)）

[root@controller ~]# openstack endpoint create --region RegionOne \
>   image public http://controller:9292
+--------------+----------------------------------+
| Field        | Value                            |
+--------------+----------------------------------+
| enabled      | True                             |
| id           | 572837d27f794675a4be0d5b32f7d442 |
| interface    | public                           |
| region       | RegionOne                        |
| region_id    | RegionOne                        |
| service_id   | 906253e30699402a9f3a52405119532c |
| service_name | glance                           |
| service_type | image                            |
| url          | http://controller:9292           |
+--------------+----------------------------------+

[root@controller ~]# openstack endpoint create --region RegionOne \
>   image internal http://controller:9292
+--------------+----------------------------------+
| Field        | Value                            |
+--------------+----------------------------------+
| enabled      | True                             |
| id           | f23f9f9af4854d49aa87076c51630e28 |
| interface    | internal                         |
| region       | RegionOne                        |
| region_id    | RegionOne                        |
| service_id   | 906253e30699402a9f3a52405119532c |
| service_name | glance                           |
| service_type | image                            |
| url          | http://controller:9292           |
+--------------+----------------------------------+

[root@controller ~]# openstack endpoint create --region RegionOne \
>   image admin http://controller:9292
+--------------+----------------------------------+
| Field        | Value                            |
+--------------+----------------------------------+
| enabled      | True                             |
| id           | 8ab8803387634f20acaf2c5443381f54 |
| interface    | admin                            |

| service_name | glance                           |
| service_type | image                            |
| url          | http://controller:9292           |
+--------------+----------------------------------+

2、安裝glance

1.安裝glance包

[root@controller ~]# yum install openstack-glance -y

2.備份配置文件并且修改（修改了4個(gè)地方）

[root@controller ~]# cp /etc/glance/glance-api.conf{,.bak}
[root@controller ~]# grep -Ev "^$|#" /etc/glance/glance-api.conf.bak > /etc/glance/glance-api.conf
[root@controller ~]# vi /etc/glance/glance-api.conf

[DEFAULT]
[cinder]
[cors]
[database]
connection = mysql+pymysql://glance:123@controller/glance
[file]
[glance.store.http.store]
[glance.store.rbd.store]
[glance.store.sheepdog.store]
[glance.store.swift.store]
[glance.store.vmware_datastore.store]
[glance_store]
stores = file,http
default_store = file
filesystem_store_datadir = /var/lib/glance/images/
[image_format]
[keystone_authtoken]
www_authenticate_uri  = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = glance
password = glance
[oslo_concurrency]
[oslo_messaging_amqp]
[oslo_messaging_kafka]
[oslo_messaging_notifications]
[oslo_messaging_rabbit]
[oslo_middleware]
[oslo_policy]
[paste_deploy]
flavor = keystone
[profiler]
[store_type_location_strategy]
[task]
[taskflow_executor]

3.同步數(shù)據(jù)庫(kù)

[root@controller ~]# su -s /bin/sh -c "glance-manage db_sync" glance

[root@controller ~]# systemctl start openstack-glance-api.service
[root@controller ~]# systemctl enable openstack-glance-api.service

4.（這一步可以不做）現(xiàn)在glance沒有日志，我們需要配置下

#[root@controller ~]# vi /etc/glance/glance-api.conf[DEFAULT]
log_file = /var/log/glance/glance-api.log
[root@controller ~]# systemctl restart openstack-glance-api.service
[root@controller ~]# tail -f /var/log/glance/glance-api.log 
).  Its value may be silently ignored in the future.

3、測(cè)試一下

下載cirros-0.4.0-x86_64-disk.img這個(gè)鏡像上傳到/opt下面（鏡像文件在我的資源csdn下載地方找到）

切換到/opt目錄下

[root@controller opt]# ls
cirros-0.4.0-x86_64-disk.img
[root@controller opt]# glance image-create --name "cirros" \
>   --file cirros-0.4.0-x86_64-disk.img \

以上說明部署glance成功

【glance鏡像服務(wù)】

它在open stack中的項(xiàng)目名稱為Glance.在早期的open stack版本中，Glance只有管理鏡像的功能，并不具備鏡像存儲(chǔ)功能?，F(xiàn)在，Glance已經(jīng)發(fā)展稱為集上傳，檢索，管理和存儲(chǔ)等多種功能的open stack核心服務(wù)。

【glance由兩部分組成】

（1）glance-api：接受云系統(tǒng)鏡像的創(chuàng)建，刪除，讀取請(qǐng)求

（2）glance-Registry：云系統(tǒng)的鏡像注冊(cè)服務(wù)

glance-api 是接受 rest api請(qǐng)求的。完成諸如鏡像的查找，獲取，上傳，刪除等操作，默認(rèn)是監(jiān)聽9292端口
glance-registry 是用于Mysql的數(shù)據(jù)交互，用戶存儲(chǔ)或獲取鏡像的元數(shù)據(jù)（metadata）；提供鏡像元數(shù)據(jù)相關(guān)的REST接口，通過glance-Registry，可以向數(shù)據(jù)庫(kù)中寫入或獲取鏡像的各種數(shù)據(jù)。glance-Registry監(jiān)聽的端口是9191.Glance數(shù)據(jù)庫(kù)中有兩種表，一張是image表，主要存儲(chǔ)了鏡像格式，大小等信息；另一張是image property表，主要存了鏡像定制化信息。
image-store是一個(gè)存儲(chǔ)的接口層，通過這個(gè)接口，glance可以獲取鏡像，image store支持的存儲(chǔ)有Amazon的S3,Openstack本身的swift，還有諸如ceph，sheepdog，GluasterFS等分布式存儲(chǔ)，image store是鏡像保存與獲取的接口，它僅僅是一個(gè)接口層，具體的實(shí)現(xiàn)需要外部的存儲(chǔ)支持。

【鏡像服務(wù)的主要功能】

1.查詢和獲取鏡像的元數(shù)據(jù)和鏡像本身
2.注冊(cè)和上傳虛擬機(jī)鏡像，包括鏡像的創(chuàng)建、上傳、下載和管理
3.維護(hù)鏡像信息，包括元數(shù)據(jù)和鏡像本身
4.支持多種方式存儲(chǔ)鏡像，包括普通的文件系統(tǒng)、swift、Amazon、S3等
5.對(duì)虛擬機(jī)實(shí)例執(zhí)行創(chuàng)建快照命令來創(chuàng)建新的鏡像，或者備份虛擬機(jī)的狀態(tài)
