一、部署Glance
1、Glance 安装
[root@linux-node1 ~]#yum install openstack-glance python-glance python-glanceclient -y
2、配置：修改glance-api和glance-registry的配置文件，同步数据库
[root@linux-node1 ~]# vi /etc/glance/glance-api.conf
[database]
connection = mysql://glance:glance@172.22.0.218/glance
[root@linux-node1 ~]# vi /etc/glance/glance-registry.conf
[database]
connection = mysql://glance:glance@172.22.0.218/glance
3、同步数据库并检查数据库：
[root@linux-node1 ~]# su -s /bin/sh -c "glance-manage db_sync" glance
检查导入glance库的表情况：
MariaDB [(none)]> use glance
Database changed
MariaDB [glance]>
MariaDB [glance]> show tables;
+----------------------------------+
| Tables_in_glance |
+----------------------------------+
| artifact_blob_locations |
| artifact_blobs |
| artifact_dependencies |
| artifact_properties |
| artifact_tags |
| artifacts |
| image_locations |
| image_members |
| image_properties |
| image_tags |
| images |
| metadef_namespace_resource_types |
| metadef_namespaces |
| metadef_objects |
| metadef_properties |
| metadef_resource_types |
| metadef_tags |
| migrate_version |
| task_info |
| tasks |
+----------------------------------+
20 rows in set (0.00 sec)
4、配置glance连接keystone，对于keystone，每个服务都要有一个用户连接keystone
[root@linux-node1 ~]# source admin-openrc.sh
[root@linux-node1 ~]# openstack user create --domain default --password=glance glance
+---------------------+----------------------------------+
| Field | Value |
+---------------------+----------------------------------+
| domain_id | d21d0715890447fb87f72e85dce6d4be |
| enabled | True |
| id | add8d7512b3a4af78236d75e5154978e |
| name | glance |
| password_expires_at | None |
+---------------------+----------------------------------+
[root@linux-node1 ~]# openstack role add --project service --user glance admin
5、修改glance-api配置文件，结合keystone和mysql
[root@linux-node1 ~]# vi /etc/glance/glance-api.conf
verbose = true
[keystone_authtoken]
auth_uri = http://172.22.0.218:5000
auth_url = http://172.22.0.218:35357
auth_plugin = password
project_domain_id = d21d0715890447fb87f72e85dce6d4be
user_domain_id = d21d0715890447fb87f72e85dce6d4be
project_name = service
username = glance
password = glance
[paste_deploy]
flavor = keystone
[oslo_messaging_notifications]
# The Drivers(s) to handle sending notifications. Possible values are messaging,
# messagingv2, routing, log, test, noop (multi valued)
# Deprecated group/name - [DEFAULT]/notification_driver
driver = noop
[glance_store]
default_store = file
filesystem_store_datadir = /var/lib/glance/images
6、修改glance-registry配置文件，结合keystone和mysql
[root@linux-node1 ~]# vi /etc/glance/glance-registry.conf
verbose=True
[oslo_messaging_notifications]
# The Drivers(s) to handle sending notifications. Possible values are messaging,
# messagingv2, routing, log, test, noop (multi valued)
# Deprecated group/name - [DEFAULT]/notification_driver
driver = noop
[keystone_authtoken]
auth_uri = http://172.22.0.218:5000
auth_url = http://172.22.0.218:35357
auth_plugin = password
project_domain_id = d21d0715890447fb87f72e85dce6d4be
user_domain_id = d21d0715890447fb87f72e85dce6d4be
project_name = service
username = glance
password = glance
[paste_deploy]
flavor = keystone
7、配置检查：
[root@linux-node1 ~]# grep -n '^[a-z]' /etc/glance/glance-api.conf
1455:verbose = true
1748:connection = mysql://glance:glance@172.22.0.218/glance
1896:default_store = file
2196:filesystem_store_datadir = /var/lib/glance/images
3192:auth_uri = http://172.22.0.218:5000
3193:auth_url = http://172.22.0.218:35357
3194:auth_plugin = password
3195:project_domain_id = d21d0715890447fb87f72e85dce6d4be
3196:user_domain_id = d21d0715890447fb87f72e85dce6d4be
3197:project_name = service
3198:username = glance
3199:password = glance
3564:driver = noop
3989:flavor = keystone
[root@linux-node1 ~]# grep -n '^[a-z]' /etc/glance/glance-registry.conf
1038:connection = mysql://glance:glance@172.22.0.218/glance
1141:auth_uri = http://172.22.0.218:5000
1142:auth_url = http://172.22.0.218:35357
1143:auth_plugin = password
1144:project_domain_id = d21d0715890447fb87f72e85dce6d4be
1145:user_domain_id = d21d0715890447fb87f72e85dce6d4be
1146:project_name = service
1147:username = glance
1148:password = glance
1494:driver = noop
1908:flavor = keystone
二、启动glance
1、设置开机启动并启动glance服务检查服务：
[root@linux-node1 ~]# systemctl enable openstack-glance-api
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-glance-api.service to /usr/lib/systemd/system/openstack-glance-api.service.
[root@linux-node1 ~]# systemctl enable openstack-glance-registry
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-glance-registry.service to /usr/lib/systemd/system/openstack-glance-registry.service.
查看galnce占用端口情况，其中9191是registry占用端口，9292是api占用端口
[root@linux-node1 ~]# netstat -lntup|egrep "9191|9292"
tcp 0 0 0.0.0.0:9292 0.0.0.0:* LISTEN 3029/python2
tcp 0 0 0.0.0.0:9191 0.0.0.0:* LISTEN 3046/python2
[root@linux-node1 ~]# ps aux | grep 3029
glance 3029 4.6 6.4 370872 65748 ? Ss 11:06 0:15 /usr/bin/python2 /usr/bin/glance-api
root 3164 0.0 0.0 112660 976 pts/0 R+ 11:11 0:00 grep --color=auto 3029
[root@linux-node1 ~]# ps aux | grep 3046
glance 3046 1.7 6.4 352560 65152 ? Ss 11:06 0:06 /usr/bin/python2 /usr/bin/glance-registry
root 3169 0.0 0.0 112660 976 pts/0 S+ 11:11 0:00 grep --color=auto 3046
2、glance服务在keystone上注册，才可以允许其他服务调用glance
[root@linux-node1 ~]# openstack service create --name glance --description "OpenStack Image service" image
+-------------+----------------------------------+
| Field | Value |
+-------------+----------------------------------+
| description | OpenStack Image service |
| enabled | True |
| id | b08581e2a35a4ed982ddfac797050ae1 |
| name | glance |
| type | image |
+-------------+----------------------------------+
[root@linux-node1 ~]# openstack endpoint create --region RegionOne image public http://172.22.0.218:9292
+--------------+----------------------------------+
| Field | Value |
+--------------+----------------------------------+
| enabled | True |
| id | af6c4a21691344d7adfd6ec3e2d3674e |
| interface | public |
| region | RegionOne |
| region_id | RegionOne |
| service_id | b08581e2a35a4ed982ddfac797050ae1 |
| service_name | glance |
| service_type | image |
| url | http://172.22.0.218:9292 |
+--------------+----------------------------------+
[root@linux-node1 ~]# openstack endpoint create --region RegionOne image internal http://172.22.0.218:9292
+--------------+----------------------------------+
| Field | Value |
+--------------+----------------------------------+
| enabled | True |
| id | 2646c93f3cda442fb062887f6c510343 |
| interface | internal |
| region | RegionOne |
| region_id | RegionOne |
| service_id | b08581e2a35a4ed982ddfac797050ae1 |
| service_name | glance |
| service_type | image |
| url | http://172.22.0.218:9292 |
+--------------+----------------------------------+
[root@linux-node1 ~]# openstack endpoint create --region RegionOne image admin http://172.22.0.218:9292
+--------------+----------------------------------+
| Field | Value |
+--------------+----------------------------------+
| enabled | True |
| id | 5cc3112ed5944f04935805467ad36ec8 |
| interface | admin |
| region | RegionOne |
| region_id | RegionOne |
| service_id | b08581e2a35a4ed982ddfac797050ae1 |
| service_name | glance |
| service_type | image |
| url | http://172.22.0.218:9292 |
+--------------+----------------------------------+
3、在admin和demo中加入glance的环境变量,告诉其他服务glance使用的环境变量，一定要在admin-openrc.sh的路径下执行
[root@linux-node1 ~]# echo "export OS_IMAGE_API_VERSION=2" | tee -a admin-openrc.sh demo-openrc.sh
export OS_IMAGE_API_VERSION=2
[root@linux-node1 ~]# tail -1 admin-openrc.sh
export OS_IMAGE_API_VERSION=2
[root@linux-node1 ~]# tail -1 demo-openrc.sh
export OS_IMAGE_API_VERSION=2
三、检查是否安装部署正确
1、如果出现以下情况，表示glance配置成功，由于没有镜像，所以看不到
[root@linux-node1 ~]# glance image-list
+----+------+
| ID | Name |
+----+------+
+----+------+
2、下载一个镜像：
[root@linux-node1 ~]#wget http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img
3、上传镜像到glance,要在上一步所下载的镜像当前目录执行:
[root@linux-node1 ~]# glance image-create --name "cirros" --file cirros-0.3.4-x86_64-disk.img --disk-format qcow2 --container-format bare --visibility public --progress
[=============================>] 100%

| visibility | public |
+------------------+--------------------------------------+
4、查看上传镜像：
[root@linux-node1 ~]# glance image-list
+--------------------------------------+--------+
| ID | Name |
+--------------------------------------+--------+
| 8f5837b4-bbec-4ef5-96f6-aba989c27206 | cirros |
+--------------------------------------+--------+
[root@linux-node1 ~]# cd /var/lib/glance/images/
[root@linux-node1 images]# ls
8f5837b4-bbec-4ef5-96f6-aba989c27206
完成部署！部署成功！
