In order to solve the problem of how to configure glance image service in openstack O version, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and easy way.

1. Create a glance database

[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'

two。 Create a keystone user about glance

[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 packages

3. Modify / etc/glance/glance-api.conf configuration file

[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. Modify / etc/glance/glance-registory.conf configuration file

[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. Create database tables, synchronize databases

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

6. Start the glance service

[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. Download the image and upload it to 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. Test whether the upload is successful

[root@controller ~] # glance image-list

+-+ +

| | ID | Name |

+-+ +

| | cdd53a8d-3bcd-43f4-a8eb-388f1eebc6b5 | cirros |

+-+ +

9. Image storage location

[root@controller ~] # ll / var/lib/glance/images/

Total 12960
