Glance主要有两个重要的服务：

Glance-api:接受云系统镜像创建、删除、读取请求。

Glance-Registry:云系统的镜像注册服务。

加载admin的环境变量：source /admin-openstack.sh

vim /admin-openstack.sh

export OS_USERNAME=admin

export OS_PASSWORD=admin

export OS_PROJECT_NAME=admin

export OS_USER_DOMAIN_NAME=default

export OS_PROJECT_DOMAIN_NAME=default

export OS_AUTH_URL=http://192.168.2.11:35357/v3

export OS_IDENTITY_API_VERSION=3

export OS_IMAGE_API_VERSION=2

注意：只要有用到openstack就要加载环境变量

//创建glance用户(控制节点)

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

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

//安装glance服务组件(控制节点)

yum install -y openstack-glance

//编辑文件 /etc/glance/glance-api.conf 并完成如下动作(控制节点)

vim /etc/glance/glance-api.conf

同步glance数据库

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

查看是否同步成功

mysql -h 192.168.2.11 -uglance -pglance -e "use glance;show tables;"

修改memcached的配置文件：vim /etc/sysconfig/memcached

PORT="11211"

USER="memcached"

MAXCONN="1024"

CACHESIZE="64"

OPTIONS="-l 192.168.2.11,::1"

systemctl enable memcached

systemctl start memcached

设置开机自启动并启动glance-api，glance-registry服务

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

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

[root@localhost log]# openstack image list

[root@localhost log]#

（没有报错就说明服务正常）

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 \
