1. 创建数据库并授权
[root@controller ~]# mysql -u root -proot
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_DBPASS';
Query OK, 0 rows affected (0.000 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY 'GLANCE_DBPASS';
Query OK, 0 rows affected (0.000 sec)
2. 创建glance用户
[root@controller ~]# openstack user create --domain default --password GLANCE_PASS glance
+---------------------+----------------------------------+
| Field | Value |
+---------------------+----------------------------------+
| domain_id | default |
| enabled | True |
| id | c9cccf601ece444a86fcba967b4633ad |
| name | glance |
| options | {} |
| password_expires_at | None |
+---------------------+----------------------------------+
给glance用户授权
[root@controller ~]# openstack role add --project service --user glance admin
3. 创建glance服务实体
[root@controller ~]# openstack service create --name glance --description "OpenStack Image" image
+-------------+----------------------------------+
| Field | Value |
+-------------+----------------------------------+
| description | OpenStack Image |
| enabled | True |
| id | 165c4d71d9354940a7efe60a9bb71211 |
| name | glance |
| type | image |
+-------------+----------------------------------+
4. 创建镜像服务API访问端点
[root@controller ~]# openstack endpoint create --region RegionOne image public http://controller:9292
+--------------+----------------------------------+
| Field | Value |
+--------------+----------------------------------+
| enabled | True |
| id | 94a3dac1cadd419f9d40e29a8dd8fed2 |
| interface | public |
| region | RegionOne |
| region_id | RegionOne |
| service_id | 165c4d71d9354940a7efe60a9bb71211 |
| 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 | c2be9485f8a7412490ca1af815041461 |
| interface | internal |
| region | RegionOne |
| region_id | RegionOne |
| service_id | 165c4d71d9354940a7efe60a9bb71211 |
| 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 | 806cde326a604e15b9bd6ecbb9340787 |
| interface | admin |
| region | RegionOne |
| region_id | RegionOne |
| service_id | 165c4d71d9354940a7efe60a9bb71211 |
| service_name | glance |
| service_type | image |
| url | http://controller:9292 |
+--------------+----------------------------------+
5. 安装glance软件包
[root@controller ~]# yum install openstack-glance -y
6. 编辑glance的配置文件
cp -a /etc/glance/glance-api.conf{,.bak}
cp -a /etc/glance/glance-registry.conf{,.bak}
grep -Ev '^$|#' /etc/glance/glance-api.conf.bak > /etc/glance/glance-api.conf
grep -Ev '^$|#' /etc/glance/glance-registry.conf.bak > /etc/glance/glance-registry.conf
openstack-config --set /etc/glance/glance-api.conf database connection mysql+pymysql://glance:GLANCE_DBPASS@controller/glance
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken www_authenticate_uri http://controller:5000
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken auth_url http://controller:5000
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken memcached_servers controller:11211
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken auth_type password
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken project_domain_name Default
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken user_domain_name Default
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken project_name service
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken username glance
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken password GLANCE_PASS
openstack-config --set /etc/glance/glance-api.conf paste_deploy flavor keystone
openstack-config --set /etc/glance/glance-api.conf glance_store stores file,http
openstack-config --set /etc/glance/glance-api.conf glance_store default_store file
openstack-config --set /etc/glance/glance-api.conf glance_store filesystem_store_datadir /var/lib/glance/images/
7. 填充glance数据库
[root@controller ~]# su -s /bin/sh -c "glance-manage db_sync" glance
8. 启动glance服务并设置开机自启
[root@controller ~]# systemctl enable openstack-glance-api.service
[root@controller ~]# systemctl start openstack-glance-api.service
启动好之后，查看端口情况，如果有9292端口，则表示glance启动成功。
[root@controller ~]# lsof -i:9292
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
glance-ap 9333 glance 4u IPv4 48361 0t0 TCP *:armtechdaemon (LISTEN)
glance-ap 9913 glance 4u IPv4 48361 0t0 TCP *:armtechdaemon (LISTEN)
9.下载cirros镜像，验证glance的安装
[root@controller ~]# wget http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img
[root@controller ~]# openstack image create --file /root/cirros-0.4.0-x86_64-disk.img --disk-format qcow2 --container-format bare --public cirros

（官方文档坑点之一，这里不要使用官方文档里面的glance image-create这样的写法，新版本的OpenStack已经不支持，尽量统一使用以openstack开头的命令写法）
[root@controller ~]# glance image-list
+--------------------------------------+--------+

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

查看镜像的物理文件
