[email protected]~]# grep ‘^[a-z]‘ /etc/glance/glance-registry.conf connection =mysql://glance:[email protected]/glance 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 flavor = keystone [[email protected]~]#
5.4 同步glance数据库
su -s/bin/sh -c "glance-manage db_sync" glance 检查数据库同步状况 [[email protected]~]# mysql -h 192.168.56.11 -uglance-pglance -e "use glance;showtables;" +----------------------------------+ |Tables_in_glance | +----------------------------------+ |artifact_blob_locations | |artifact_blobs | |artifact_dependencies | |artifact_properties | |artifact_tags | |artifacts | |image_locations | |image_members | |image_properties | |image_tags | |images | |metadef_namespace_resource_types | |metadef_namespaces | |metadef_objects | |metadef_properties | |metadef_resource_types | |metadef_tags | |migrate_version | |task_info | |tasks | +----------------------------------+ [[email protected]~]#
5.5 往keystone注册

5.8 添加glance-api的调用版本号
在admin-openstack.shdemo-openstack.sh 里面要有 exportOS_IMAGE_API_VERSION=2
5.9 测试是否成功
[[email protected]~]# glance image-list +----+------+ | ID | Name | +----+------+ +----+------+ [[email protected]~]#
5.10 下载一个镜像测试
wgethttp://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img
5.11 上传镜像到glance
openstack image create "cirros" \ --file cirros-0.3.4-x86_64-disk.img \ --disk-format qcow2 --container-format bare \ --public
