Centos7.4安装openstack（queens）详细安装部署（三）－镜像服务（glance）安装

一、安装镜像服务

　　1.1、控制节点）配置镜像数据库

mysql -u root -pADMIN_PASS

　　1.2、创建glance数据库并设置访问权限

CREATE DATABASE glance;
  
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY 'ADMIN_PASS';
   
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY 'ADMIN_PASS';

　　1.3、（控制节点）创建glance认证相关信息

openstack user create --domain default --password ADMIN_PASS glance                    创建glance用户

openstack role add --project service --user glance admin                               将glance用户加入service项目，并设置admin角色
 
openstack service create --name glance --description "OpenStack Image" image           创建镜像服务

openstack endpoint create --region RegionOne image public http://controller:9292       创建镜像api端口

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

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

二、（控制节点）安装软件包并配置配置文件

　　1.1、安装软件包

yum install openstack-glance -y

　　1.2、编辑/etc/glance/glance-api.conf文件并完成下面配置

cp /etc/glance/glance-api.conf{,.bak}
grep '^[a-z\[]' /etc/glance/glance-api.conf.bak >/etc/glance/glance-api.conf

[database]
connection = mysql+pymysql://glance:ADMIN_PASS@controller/glance

[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = glance
password = ADMIN_PASS

[paste_deploy]
flavor = keystone

　　1.3、编辑/etc/glance/glance-registry.conf文件，完成以下配置

cp /etc/glance/glance-registry.conf{,.bak}                       　　
grep '^[a-z\[]' /etc/glance/glance-registry.conf.bak >/etc/glance/glance-registry.conf

[database]
connection = mysql+pymysql://glance:ADMIN_PASS@controller/glance
 
[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = glance
password = ADMIN_PASS

[paste_deploy]
flavor = keystone

　　1.4、同步数据库

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

　　1.5、（控制节点）设置服务的开机自启动，并启动服务

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

三、（控制节点）验证操作 

　　1.1、下载镜像

yum install wget -y
wget http://download.cirros-cloud.net/0.3.5/cirros-0.3.5-x86_64-disk.img

　　1.2、上传镜像

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

　　1.3、确认下镜像是否成功上传

openstack image list
