接上一篇keystone, 这一篇介绍glance服务：
- 在开始操作之前，先用source环境变量，然后创建glance 用户，并设置密码为glance
[root@linux-node1 ~]#openstack user create --domain default --password-prompt glance
User Password:
Repeat User Password:
+---------------------+----------------------------------+
| Field | Value |
+---------------------+----------------------------------+
| domain_id | default |
| enabled | True |
| id | 31a0d9b7dd5f47b4b30ed4a77500a307 |
| name | glance |
| options | {} |
| password_expires_at | None |
+---------------------+----------------------------------+
- 添加admin角色到glance用户和service project
[root@linux-node1 ~]# openstack role add --project service --user glance admin
[root@linux-node1 ~]#
- 编辑/etc/glance/glance-registry.conf 如下所示
[database]
# ...
connection = mysql+pymysql://glance:glance@192.168.56.11/glance
[keystone_authtoken] auth_uri = http://192.168.56.11:5000
auth_url = http://192.168.56.11:35357
memcached_servers = 192.168.56.11:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = glance
password = glance
[paste_deploy]
flavor = keystone
- 编辑/etc/glance/glance-api.conf 如下所示：
[database]
connection = mysql+pymysql://glance:glance@192.168.56.11/glance
[keystone_authtoken]
auth_uri = http://192.168.56.11:5000
auth_url = http://192.168.56.11:35357
memcached_servers = 192.168.56.11:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = glance
password = glance
[paste_deploy]
flavor = keystone
[glance_store]
stores = file,http
default_store = file
filesystem_store_datadir = /var/lib/glance/images
- 同步glance数据库
[root@linux-node1 ~]# su -s /bin/sh -c "glance-manage db_sync" glance
- 验证数据库是否同步
[root@linux-node1 ~]# mysql -h 192.168.56.11 -uglance -pglance -e "use glance;show tables"

- 启动memcached并设置开机启动
[root@linux-node1 ~]# systemctl enable memcached
[root@linux-node1 ~]# systemctl start memcached
- 启动glance服务并设置开机启动
systemctl enable openstack-glance-api.service \
openstack-glance-registry.service
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-glance-api.service

systemctl start openstack-glance-api.service \
openstack-glance-registry.service
- 创建glance实例
openstack service create --name glance \

- 创建glance服务API 端点
openstack endpoint create --region RegionOne \

- 验证创建，现在是两个服务的六个端点
[root@linux-node1 ~]# openstack endpoint list

+----------------------------------+-----------+--------------+--------------+---------+-----------+--------------------------------+
- 这个时候，输入openstack image list,如果没有报错，即证明上面的操作是对的
[root@linux-node1 ~]# openstack image list
[root@linux-node1 ~]#
- 下面我们用一个小镜像来验证一下，首先先获取这个镜像
wget http://download.cirros-cloud.net/0.3.5/cirros-0.3.5-x86_64-disk.img
- 创建并验证镜像
openstack image create "cirros" \
--file cirros-0.3.-x86_64-disk.img \
--disk-format qcow2 --container-format bare \
--public
