openstack(三)配置glance服务

布署glance

Glance是Openstack镜像服务组件，监听在9292端口，接收REST API请求，通过其它模块来完成镜像的获取，上传，删除等。

在创建虚拟机的时候，先把镜像上传到glace，

glance-api接收镜像的删除、上传和读取；

glance-registry(port:9191)与mysql交互，存储获取镜像的元数据。

glance数据库有两张表，一张image表，一张image property表：保存了镜像格式、大小等信息

image store是一个存储的接口层，通过这个接口glance可以获取镜像

1. 控制端安装glance

yum -y install openstack-glance

2. 在数据库数据库与用户

mysql -uroot -p123

MariaDB [(none)]> create database glance;

MariaDB [(none)]> grant all on glance.* to 'glance'@'%' identified by '123';

验证glance用户连接

mysql -hopenvip.com -uglance -p123

3. 编辑配置文件/etc/glance/glance-api.conf

sed -i -e '/^#/d' -e '/^$/d' /etc/glance/glance-api.conf

最终如下

[DEFAULT] [cinder] [cors] [database] connection = mysql+pymysql://glance:123@openvip.com/glance [file] [glance.store.http.store] [glance.store.rbd.store] [glance.store.sheepdog.store] [glance.store.swift.store] [glance.store.vmware_datastore.store] [glance_store] stores = file,http default_store = file filesystem_store_datadir = /var/lib/glance/images [image_format] [keystone_authtoken] www_authenticate_uri = http://controller:5000 auth_url = http://controller:5000 memcached_servers = openvip.com:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = glance password = 123 [oslo_concurrency] [oslo_messaging_amqp] [oslo_messaging_kafka] [oslo_messaging_notifications] [oslo_messaging_rabbit] [oslo_middleware] [oslo_policy] [paste_deploy] flavor = keystone [profiler] [store_type_location_strategy] [task] [taskflow_executor]

4. 编辑配置文件/etc/glance/glance-registry.conf

sed -i -e '/^#/d' -e '/^$/d' /etc/glance/glance-registry.conf

最终如下

[DEFAULT] [database] connection = mysql+pymysql://glance:123@openvip.com/glance [keystone_authtoken] www_authenticate_uri = http://controller:5000 auth_url = http://controller:5000 memcached_servers = openvip.com:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = glance password = 123 [oslo_messaging_amqp] [oslo_messaging_kafka] [oslo_messaging_notifications] [oslo_messaging_rabbit] [oslo_policy] [paste_deploy] flavor = keystone [profiler]

6. 初始化glance数据库

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

验证数据库

7. 启动glance并设置为开机启动

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

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

验证glance端口(9191,9292)
