3. 安装 glance（控制节点）— OpenStack Queens 三节点部署
Glance服务只需安装在控制节点上
在keystone中为Glance添加用户等

为glance创建数据库和用户
root@controller ~(keystone)# mysql

安装配置Glance
安装glance
root@controller ~(keystone)# apt -y install glance
配置glance，由于官方配置文件修改较为麻烦，这里直接创建一个新的配置文件
root@controller ~(keystone)# mv /etc/glance/glance-api.conf /etc/glance/glance-api.conf.org
root@controller ~(keystone)# vi /etc/glance/glance-api.conf
# 添加以下内容，保存退出
[DEFAULT]
bind_host = 0.0.0.0
[glance_store]
default_store = file
filesystem_store_datadir = /var/lib/glance/images/
[database]
connection = mysql+pymysql://glance:root@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 = root
[paste_deploy]
flavor = keystone
root@controller ~(keystone)# mv /etc/glance/glance-registry.conf /etc/glance/glance-registry.conf.org
root@controller ~(keystone)# vi /etc/glance/glance-registry.conf
# 添加以下内容，保存退出
[DEFAULT]
bind_host = 0.0.0.0
[database]
# MariaDB connection info
connection = mysql+pymysql://glance:root@controller/glance
# Keystone auth info
[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 = root
[paste_deploy]
flavor = keystone
由于配置文件是新建的，需要将权限加回去
root@controller ~(keystone)# chmod 644 /etc/glance/glance-api.conf /etc/glance/glance-registry.conf
root@controller ~(keystone)# chown glance. /etc/glance/glance-api.conf /etc/glance/glance-registry.conf
同步数据库
root@controller ~(keystone)# su -s /bin/bash glance -c "glance-manage db_sync"
...
...
Database is synced successfully.
重启服务
root@controller ~(keystone)# systemctl restart glance-api glance-registry
在glance中添加镜像
下载官方用于测试的一个小系统Cirros
root@controller ~(keystone)# wget http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img
添加该镜像到镜像服务
root@controller ~(keystone)# openstack image create "cirros" \
--file cirros-0.4.0-x86_64-disk.img \
--disk-format qcow2 --container-format bare \
--public

查看镜像列表
root@controller ~(keystone)# openstack image list
+--------------------------------------+--------+--------+

参考
容器就很酷。
