OpenStack组件系列☞glance搭建
第一步：glance关于数据库的操作mysql -u root -p #登入数据库
CREATE DATABASE glance; #新建库keystone
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \
IDENTIFIED BY '123'; #新建本地访问glance库的账号
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' \
IDENTIFIED BY '123'; #新建远程访问glance库的账号
第二部：glance关于keystone的操作
soure admin-openrc #执行管理员脚本
#为glance的使用者创建用户
openstack user create --domain default --password-prompt glance
#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。
openstack role add --project service --user glance admin
#创建glance服务的catalog：service+endpoint
openstack service create --name glance \
--description "OpenStack Image" image
openstack endpoint create --region RegionOne \
image public http://106.14.254.63:9292
openstack endpoint create --region RegionOne \
image internal http://106.14.254.63:9292
openstack endpoint create --region RegionOne \
image admin http://106.14.254.63:9292
第三步：安装软件包
yum -y install openstack-glance
第四步：配置/etc/glance/glance.conf
先要创建本地存储文件：
mkdir -p /var/lib/glance/images
chown -R glance.glance /var/lib/glance/images
然后再开始配置/etc/glance/glance-api.conf
connection = mysql+pymysql://glance:123@106.14.254.63/glance
auth_uri = http://106.14.254.63:5000
auth_url = http://106.14.254.63:35357
memcached_servers = 106.14.254.63:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = glance
password = 123
flavor = keystone
stores = file,http
default_store = file
filesystem_store_datadir = /var/lib/glance/images/
配置/etc/glance/glance-registry.conf
connection = mysql+pymysql://glance:123@106.14。254.63/glance
第五步：初始化glanceshujuku：
su -s /bin/sh -c "glance-manage db_sync" glance
'''
忽略以下打印，此乃正常性行为：
Option "verbose" from group "DEFAULT" is deprecated for removal.Its value may be silently ignored in the future.
/usr/lib/python2.7/site-packages/oslo_db/sqlalchemy/enginefacade.py:1171:...... oslo_db.sqlalchemy.enginefacade
...... a future release.")
result = self._query(query)
'''
第六步：启动glance且设置开机启动
systemctl enable openstack-glance-api.service \
openstack-glance-registry.service
systemctl start openstack-glance-api.service \
openstack-glance-registry.service
LAST：验证glance功能：
source admin-openrc
#如果没有wget则必须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
openstack image list
