部署Glance
1、创建glance数据库、用户、表
登录MySQL客户端，创建数据库和用户，并授权相应的数据库权限
[root@controller ~]# mysql -u root -p000000
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 22
Server version: 10.3.20-MariaDB MariaDB Server
Copyright © 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type ‘help;’ or ‘\h’ for help. Type ‘\c’ to clear the current input statemen
MariaDB [(none)]> CREATE DATABASE glance;
Query OK, 1 row affected (0.000 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance. TO ‘glance’@‘localhost’ IDENTIFIED BY ‘glance’;*
Query OK, 0 rows affected (0.001 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance. TO ‘glance’@‘controller’ IDENTIFIED BY ‘glance’;*
Query OK, 0 rows affected (0.000 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance. TO ‘glance’@’%’ IDENTIFIED BY ‘glance’;*
Query OK, 0 rows affected (0.000 sec)
MariaDB [(none)]> exit
Bye
2、创建OpenStack中的glance用户
创建用户之前，需要先执行管理员环境变量脚本
[root@controller ~]# ./admin-openrc
[root@controller ~]# openstack user create --domain default --password-prompt glance
User Password:000000
Repeat User Password:000000
±--------------------±---------------------------------+
| Field | Value |
±--------------------±---------------------------------+
| domain_id | default |
| enabled | True |
| id | 0c968195a7a54fe690c5dd755a8030f7 |
| name | glance |
| options | {} |
| password_expires_at | None |
±--------------------±---------------------------------+
[root@controller ~]# openstack role add --project service --user glance admin
[root@controller ~]# openstack service create --name glance --description “OpenStack Image” image
±------------±---------------------------------+
| Field | Value |
±------------±---------------------------------+
| description | OpenStack Image |
| enabled | True |
| id | 62cb2bbb9ffd42d289a3791aff402a76 |
| name | glance |
| type | image |
±------------±---------------------------------+
3、创建镜像服务API端点
[root@controller ~]# openstack endpoint create --region RegionOne image public http://controller:9292
±-------------±---------------------------------+
| Field | Value |
±-------------±---------------------------------+
| enabled | True |
| id | 41f1e1a662fc4db8a9f27677ed5a0dd7 |
| interface | public |
| region | RegionOne |
| region_id | RegionOne |
| service_id | 62cb2bbb9ffd42d289a3791aff402a76 |
| 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 | 3e4e422427b143aeba70a99bb4cb1200 |
| interface | internal |
| region | RegionOne |
| region_id | RegionOne |
| service_id | 62cb2bbb9ffd42d289a3791aff402a76 |
| 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 | 1fcda8fb74d9477497cd828fafec03a6 |
| interface | admin |
| region | RegionOne |
| region_id | RegionOne |
| service_id | 62cb2bbb9ffd42d289a3791aff402a76 |
| service_name | glance |
| service_type | image |
| url | http://controller:9292 |
±-------------±---------------------------------+
4、安装glance包
[root@controller ~]# yum install -y openstack-glance
5、配置/etc/glance/glance-api.conf文件
在配置文件的相应位置添加以下配置内容
[root@controller ~]# vim /etc/glance/glance-api.conf
[database]
connection = mysql+pymysql://glance:glance@controller/glance
[keystone_authtoken]
auth_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 = 000000
[paste_deploy]
lavor = keystone
[glance_store]
stores = file,http
default_store = file
filesystem_store_datadir = /var/lib/glance/images/
6、配置/etc/glance/glance-registry.conf文件
在配置文件的相应位置添加以下配置内容
[root@controller ~]# vim /etc/glance/glance-registry.conf
[database]
connection=mysql+pymysql://glance:glance@controller/glance
[keystone_authtoken]
auth_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 = 000000
[paste_deploy]
flavor = keystone
7、初始化glance数据库
[root@controller ~]# su -s /bin/sh -c “glance-manage db_sync” glance
INFO [alembic.runtime.migration] Context impl MySQLImpl.
INFO [alembic.runtime.migration] Will assume non-transactional DDL.
/usr/lib/python2.7/site-packages/pymysql/cursors.py:170: Warning: (1280, u"Name ‘alembic_version_pkc’ ignored for PRIMARY key.")
result = self._query(query)

Database is synced successfully.
8、启动glance相关服务
[root@controller ~]# systemctl start openstack-glance-api.service && systemctl start openstack-glance-registry.service
[root@controller ~]# systemctl enable openstack-glance-api.service && systemctl enable openstack-glance-registry.service
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-glance-api.service to /usr/lib/systemd/system/openstack-glance-api.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-glance-registry.service to /usr/lib/systemd/system/openstack-glance-registry.service.
9、验证操作
执行admin环境变量脚本，从互联网下载测试镜像“cirros”并导入glance，查看是否创建成功
[root@controller ~]# ./admin-openrc
[root@controller ~]# openstack image list
[root@controller ~]# wget http://download.cirros-cloud.net/0.3.5/cirros-0.3.5-x86_64-disk.img
[root@controller ~]# openstack image create “cirrors” --file cirros-0.3.5-x86_64-disk.img --disk-format qcow2 --container-format bare
