OpenStack Trail 部署文档（四）部署Glance服务

镜像服务Glance

官方文档：https://docs.openstack.org/glance/train/install/ 

1、初始化数据库

MariaDB [(none)]> CREATE DATABASE glance;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY 'glance123';

2、创建glance用户：

[root@openstack-controller ~]# openstack user create --domain default --password-prompt glance 
User Password: glance
Repeat User Password: glance

3、创建服务并加入service项目：

[root@openstack-controller ~]# openstack role add --project service --user glance admin
[root@openstack-controller ~]# openstack service create --name glance --description "OpenStack Image" image

4、创建endpoint：

[root@openstack-controller ~]# openstack endpoint create --region RegionOne image public http://openstack-controller.local:9292 
[root@openstack-controller ~]# openstack endpoint create --region RegionOne image internal http://openstack-controller.local:9292 
[root@openstack-controller ~]# openstack endpoint create --region RegionOne image admin http://openstack-controller.local:9292

5、安装glance软件包

[root@openstack-controller ~]# yum install openstack-glance

6、配置glance：/etc/glance/glance-api.conf

[database]
connection = mysql+pymysql://glance:glance123@openstack-controller.local/glance
......
[glance_store]
stores = file
default_store = file
filesystem_store_datadir = /var/lib/glance/images/
......
[keystone_authtoken]
www_authenticate_uri  = http://openstack-controller.itcast.cn:5000
auth_url = http://openstack-controller.itcast.cn:5000
memcached_servers = openstack-controller.itcast.cn:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = glance 
password = glance 
......
[paste_deploy]
flavor = keystone 

7、初始化数据库

[root@openstack-controller ~]# su -s /bin/sh -c "glance-manage db_sync" glance

8、启动glance服务

[root@openstack-controller ~]# systemctl enable openstack-glance-api.service 
[root@openstack-controller ~]# systemctl start openstack-glance-api.service

---

重启方法：systemctl restart openstack-glance-api.service
镜像存放路径：/var/lib/glance/images/
日志存放路径：/var/log/glance/api.log

创建镜像：

[root@openstack-controller ~]# wget http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img
[root@openstack-controller ~]# glance image-create --name "cirros-0.4.0" --file cirros-0.4.0-x86_64-disk.img --disk-format qcow2 --container-format bare --visibility public

    * --name：指定镜像名称
    * --file：指定镜像文件
    * --disk-format：指定镜像格式
    * --container-format：指定磁盘类型
    * --visibility：指定镜像访问方式
