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




# 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



# source  admin-openrc

　　然后在创建glance用户：



# 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：




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

　　为glance创建服务实体：



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

为镜像服务创建API endpoints：




# 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：



# yum install openstack-glance

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



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

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



[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：



[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：



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

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



[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：



# 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：




# 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？



# 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

# 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
