照着官网来安装openstack pike之glance安装

镜像服务image service（glance）的安装还是在控制节点上进行：

1、前提条件，数据库为glance创建库和账户密码来连接数据库

?

1 2 3 4

# mysql -u root -p MariaDB [(none)]> CREATE DATABASE glance; MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY 'glance'; MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%'IDENTIFIED BY 'glance';

 2、在为glance在keystone上创建用户项目等时，需要先连接keystone，这里使用keystone的admin账号来登录

?

1	# source  admin-openrc

 然后在创建glance用户：

?

1	# openstack user create --domain default --password-prompt glance

 输入密码：glance

将admin角色添加到glance用户和service项目中：

?

1	# openstack role add --project service --user glance admin

 为glance创建服务实体：

?

1	# openstack service create --name glance --description "OpenStack Image" image

 

为镜像服务创建API endpoints：

?

1 2 3

# openstack endpoint create --region RegionOne image public http://192.168.101.10:9292 # openstack endpoint create --region RegionOne image internal http://192.168.101.10:9292 # openstack endpoint create --region RegionOne image admin http://192.168.101.10:9292

 安装和配置glance：

?

1	# yum install openstack-glance

 修改配置文件：/etc/glance/glance-api.conf，在[database]部分：

?

1	connection = mysql+pymysql://glance:glance@192.168.101.10/glance

 在[keystone_authtoken]和[paste_deploy]分别做如下设置：

?

1 2 3 4 5 6 7 8 9 10 11 12 13

[keystone_authtoken] auth_uri = http://192.168.101.10:5000 auth_url = http://192.168.101.10:35357 memcached_servers = 192.168.101.10:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = glance password = glance   [paste_deploy] flavor = keystone

 在[glance_store]部分设置一个本地文件系统用来存储本地镜像：

?

1 2 3 4

[glance_store] stores = file,http default_store = file filesystem_store_datadir = /var/lib/glance/images/

 修改配置文件：/etc/glance/glance-registry.conf，在[database]配置数据库的连接：

?

1	connection = mysql+pymysql://glance:glance@192.168.101.10/glance

 在[keystone_authtoken]和[paste_deploy]配置如下内容：

?

1 2 3 4 5 6 7 8 9 10 11 12 13

[keystone_authtoken] auth_uri = http://192.168.101.10:5000 auth_url = http://192.168.101.10:35357 memcached_servers = 192.168.101.10:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = glance password = glance   [paste_deploy] flavor = keystone

 向glance库导入填充数据：

?

1	# su -s /bin/sh -c "glance-manage db_sync" glance

 　　Ignore any deprecation messages in this output.

验证glance是否有table？

最后开启glance服务：

?

1 2	# systemctl enable openstack-glance-api.service openstack-glance-registry.service # systemctl start openstack-glance-api.service openstack-glance-registry.service

 校验glance：校验image service是否安装成功？

?

1 2 3

# source admin-openrc # wget http://download.cirros-cloud.net/0.3.5/cirros-0.3.5-x86_64-disk.img # openstack image create "cirros" --file cirros-0.3.5-x86_64-disk.img --disk-format qcow2 --container-format bare --public

 上传镜像到镜像服务上，使用格式qcow2磁盘格式，权限为public，所有的项目都能访问它

?

1	# openstack image list    查看镜像列表

 

至此glance的image service组件安装成功

 

贴出glance两个配置文件的配置：

1、/etc/glance/glance-api.conf

?

 2、配置文件/etc/glance/glance-registry.conf

?
