OpenStack 运维 - 部署Glance组件

• 一、创建数据库实例和数据库用户
• 二、创建用户修改配置文件
• 三、创建镜像服务API
• 四、安装OpenStack-glance
• 五、修改glance配置文件
• 六、初始化glance数据库
• • ① 开启服务
  • ② 查看端口
  • ③ 赋予glance服务的读写权限
• 七、导入镜像
• • ① 查看镜像

一、创建数据库实例和数据库用户

mysql -u root -p

create database glance;

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

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

flush privileges;

exit

二、创建用户修改配置文件

#创建用户
openstack user create --domain default --password GLANCE_PASS glance	

#添加服务和用户权限glance为管理员
openstack role add --project service --user glance admin

#创建新的服务类型镜像
openstack service create --name glance --description "OpenStack Image" image

openstack service list

三、创建镜像服务API

使用三种API端点代表三种服务：admin、internal、public

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

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

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

四、安装OpenStack-glance

yum -y install openstack-glance

五、修改glance配置文件

配置文件：glance-api.conf 、 glance-registry.conf

cp -a /etc/glance/glance-api.conf,.bak
grep -Ev '^$|#' /etc/glance/glance-api.conf.bak > /etc/glance/glance-api.conf

openstack-config --set /etc/glance/glance-api.conf database connection mysql+pymysql://glance:GLANCE_DBPASS@ct/glance
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken www_authenticate_uri http://ct:5000
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken auth_url http://ct:5000
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken memcached_servers ct:11211
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken auth_type password
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken project_domain_name Default
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken user_domain_name Default
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken project_name service
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken username glance
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken password GLANCE_PASS
openstack-config --set /etc/glance/glance-api.conf paste_deploy flavor keystone
openstack-config --set /etc/glance/glance-api.conf glance_store stores file,http
openstack-config --set /etc/glance/glance-api.conf glance_store default_store file
openstack-config --set /etc/glance/glance-api.conf glance_store filesystem_store_datadir /var/lib/glance/images/

openstack-config --set /etc/glance/glance-api.conf glance_store filesystem_store_datadir /var/lib/glance/images/

六、初始化glance数据库

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

① 开启服务

systemctl enable openstack-glance-api
systemctl start openstack-glance-api

② 查看端口

netstat -natp | grep 9292

③ 赋予glance服务的读写权限

chown -hR glance:glance /var/lib/glance/

七、导入镜像

openstack image create --file cirros-0.3.5-x86_64-disk.img --disk-format qcow2 --container-format bare --public cirros

① 查看镜像

openstack image list

glance image-list
