OpenStack 安装:glance 安装

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
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.
systemctl start openstack-glance-api.service 
  openstack-glance-registry.service

• 创建glance实例

openstack service create --name glance 
  --description "OpenStack Image" image
+-------------+----------------------------------+
| Field       | Value                            |

| name        | glance                           |
| type        | image                            |
+-------------+----------------------------------+

• 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

• 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-0.3.5-x86_64-disk.img 
  --disk-format qcow2 --container-format bare 
  --public
