openstack之~glance安装部署
接着部署完keystone后，接着部署glance第一：部署安装glance
glance关于数据库的操作：
# mysql -u root -p

glance与keystone的关联操作：
# source admin-openrc#执行管理者脚本
# openstack user create --domain default --password-prompt glance #为glance创建用户

# openstack role add --project service --user glance admin#对glance-service添加role角色,提示：用户glance只有在一个确定的项目service内才有角色的概念，单独的用户或者单独的项目都是无法绑定角色的

#创建glance服务的catalog：service+endpoint(uri)
openstack endpoint create --region RegionOne \
image public http://192.168.31.57:9292
openstack endpoint create --region RegionOne \
image internal http://192.168.31.57:9292
openstack endpoint create --region RegionOne \
image admin http://192.168.31.57:9292
安装：glance的软件包
yum -y install openstack-glance
配置glance
创建本地存储：
1.必须在openstack-glance-api.service服务启动之前配置好存储设备，因为服务启动的时候会加载存储驱动检索存储设备，如过启动之前没有存储设备，启动后再键存储设备的话，也是没用的，最终让你镜像传不上去
2.一定要赋予openstack-glance-api.service服务对文件存储设备的写权限
首先：
mkdir /var/lib/glance/images
chown -R glance.glance /var/lib/glance/images
配置/etc/glance/glance-api.conf
connection = mysql+pymysql://glance:123@192.168.1.120/glance#链接glance的数据库
auth_uri = http://192.168.1.120:5000 #普通用户认证uri
auth_url = http://192.168.1.120:35357 #admin用户认证uri
memcached_servers = 192.168.1.120:11211 #memcached的uri （目前还没有配置）
auth_type = password #认证类型密码
project_domain_name = Default #项目域名
user_domain_name = Default #用户域名
project_name = service #项目名字
username = glance #glance用户
password = 123 #glance密码
flavor = keystone
stores = file,http #存储设备
default_store = file
filesystem_store_datadir = /var/lib/glance/images/ 镜像存放位置
配置/etc/glance/glance-registry.conf
connection = mysql+pymysql://glance:123@192.168.1.120/glance#连接数据库
官网上在此还配置这与keystone的认证机制，这里不用配置哦！
初始化glance数据库：
su -s /bin/sh -c "glance-manage db_sync" glance
报这个错误不用管，是正常的
启动glance，并设置开机自启动
systemctl enable openstack-glance-api.service \
openstack-glance-registry.service
systemctl start openstack-glance-api.service \
openstack-glance-registry.service
第二：验证
一
source admin-openrc
yum -y install wget
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

到此为止完成了glance的搭建，验证了从glance的命令行上传镜像已经成功。
二：
用horizon管理页面上传镜像
打开http://192.168.1.120/dashboard
点击创建镜像，上传后在机器上查看镜像id号是相同的，及正确
第三：查看信息
查看catalog信息：
现在可以查看下service列表
