openstack O版如何配置glance镜像服务，针对这个问题，这篇文章详细介绍了相对应的分析和解答，希望可以帮助更多想解决这个问题的小伙伴找到更简单易行的方法。
1.创建glance数据库
[root@controller ~]# mysql -uroot -pdevops
MariaDB [(none)]> CREATE DATABASE glance;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance. TO 'glance'@'localhost' IDENTIFIED BY 'devops';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance. TO 'glance'@'%' IDENTIFIED BY 'devops';
2.创建关于glance的 keystone用户
[root@controller ~]# source /root/admin-openrc.sh
[root@controller ~]#openstack user create --domain default glance --password devops
openstack role add --project service --user glance admin
[root@controller ~]# openstack service create --name glance --description "OpenStack Image service" image
openstack endpoint create --region RegionOne image public http://controller:9292
openstack endpoint create --region RegionOne image internal http://controller:9292
openstack endpoint create --region RegionOne image admin http://controller:9292
[root@controller ~]# yum -y install openstack-glance 35个包
3.修改/etc/glance/glance-api.conf 配置文件
[root@controller ~]# cp /etc/glance/glance-api.conf /etc/glance/glance-api.conf.bak
[root@controller ~]# >/etc/glance/glance-api.conf
[root@controller ~]# cat /etc/glance/glance-api.conf
[DEFAULT]
transport_url = rabbit://openstack:devops@controller
[database]
connection = mysql+pymysql://glance:devops@controller/glance
[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
username = glance
password = devops
project_name = service
[paste_deploy]
flavor = keystone
[glance_store]
stores = file,http
default_store = file
filesystem_store_datadir = /var/lib/glance/images/
[root@controller ~]# cat /etc/glance/glance-api.conf | grep -v "^#" | grep -v "^$"
4.修改/etc/glance/glance-registory.conf配置文件
[root@controller ~]# cp /etc/glance/glance-registry.conf /etc/glance/glance-registry.conf.bak
[root@controller ~]# >/etc/glance/glance-registry.conf
[root@controller ~]# cat /etc/glance/glance-registry.conf
[DEFAULT]
transport_url = rabbit://openstack:devops@controller
[database]
connection = mysql+pymysql://glance:devops@controller/glance
[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = glance
password = devops
[paste_deploy]
flavor = keystone
[root@controller ~]# cat /etc/glance/glance-registry.conf | grep -v "^#" | grep -v "^$"
5.创建数据库表，同步数据库
[root@controller ~]# su -s /bin/sh -c "glance-manage db_sync" glance
6.启动glance服务
[root@controller ~]#systemctl enable openstack-glance-api.service openstack-glance-registry.service
[root@controller ~]# systemctl start openstack-glance-api.service
[root@controller ~]# systemctl start openstack-glance-registry.service
[root@controller ~]# netstat -anpult | grep 9191 #registry
tcp 0 0 0.0.0.0:9191 0.0.0.0: LISTEN 31349/python2
[root@controller ~]# netstat -anpult | grep 9292 #api
tcp 0 0 0.0.0.0:9292 0.0.0.0: LISTEN 31413/python2
7.下载镜像并上传到glance
[root@controller ~]# wget http://download.cirros-cloud.net/0.3.5/cirros-0.3.5-x86_64-disk.img
[root@controller ~]# openstack image create "cirros" --file cirros-0.3.5-x86_64-disk.img --disk-format qcow2 --container-format bare --public
8.测试是否上传成功
[root@controller ~]# glance image-list
+--------------------------------------+--------+
| ID | Name |
+--------------------------------------+--------+
| cdd53a8d-3bcd-43f4-a8eb-388f1eebc6b5 | cirros |
+--------------------------------------+--------+
9.镜像存放位置
[root@controller ~]# ll /var/lib/glance/images/
total 12960
-rw-r-----. 1 glance glance 13267968 May 5 08:25 cdd53a8d-3bcd-43f4-a8eb-388f1eebc6b5
