OpenStack搭建glance

1.创建数据库

mysql -uroot -p 

create database glance;

grant all privileges on glance.* to glance@'localhost' identified by '123456';

grant all privileges on glance.* to glance@'%' identified by '123456';

grant all privileges on glance.* to glance@'controller' identified by '123456';

flush privileges;

2.keystone认证操作:

所有后续项目的部署都统一放到一个租户service里,然后需要为每个项目建立用户,建管理员角色,建立关联

. admin-openrc

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

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

建立服务实体

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

建端点

openstack endpoint create --region RegionOne image public http://controller:9292

openstack endpoint create --region RegionOne image internal http://controller:9292

openstack endpoint create --region RegionOne image admin http://controller:9292

3.安装软件

yum install openstack-glance -y

4.初始化存放镜像的存储设备,此处我们暂时用本地存储,但是无论哪种存储,都应该在glance启动前就已经有了,否则glance启动时通过驱动程序检索不到存储设备,即在glance启动后 新建的存储设备无法被glance识别到,需要重新启动glance才可以,因此我们将下面的步骤提到了最前面。

新建目录:

mkdir -p /var/lib/glance/images/

chown glance.glance /var/lib/glance/images/

5.修改配置:

编辑:/etc/glance/glance-api.conf 

[database]

#这里的数据库连接配置是用来初始化生成数据库表结构,不配置无法生成数据库表结构

#glance-api不配置database对创建vm无影响,对使用metada有影响

#日志报错:ERROR glance.api.v2.metadef_namespaces

connection = mysql+pymysql://glance:123456@controller/glance

[keystone_authtoken]

auth_url = http://controller:5000

memcached_servers = controller:123456

auth_type = password

project_domain_name = default

user_domain_name = default

project_name = service

username = glance

password = 123456

[paste_deploy]

flavor = keystone

 

[glance_store]

stores = file,http

default_store = file

filesystem_store_datadir = /var/lib/glance/images/

 

编辑:/etc/glance/glance-registry.conf

 

[database]

#这里的数据库配置是用来glance-registry检索镜像元数据

connection = mysql+pymysql://glance:123456@controller/glance

同步数据库:(此处会报一些关于future的问题,自行忽略)

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

 

启动服务:

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

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

  

二:验证操作:

. admin-openrc

wget http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img

openstack image create "cirros" --file cirros-0.3.4-x86_64-disk.img --disk-format qcow2 --container-format bare --public

openstack image list  有如下截屏所示,就表示glance服务部署好了
