openstack安装newton版本Glance部署（二）

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                            |
+----------------------------------+
 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
:verbose = true
:connection = mysql://glance:glance@172.22.0.218/glance
:default_store = file
:filesystem_store_datadir = /var/lib/glance/images
: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
:driver =  noop
:flavor = keystone
[root@linux-node1 ~]# grep -n '^[a-z]' /etc/glance/glance-registry.conf
:connection = mysql://glance:glance@172.22.0.218/glance
: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
:driver = noop
: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:            0.0.0.0:*               LISTEN      /python2
tcp               0.0.0.0:            0.0.0.0:*               LISTEN      /python2
[root@linux-node1 ~]# ps aux | grep
glance      4.6  6.4   ?        Ss   :   : /usr/bin/python2 /usr/bin/glance-api
root        0.0  0.0     pts/    R+   :   : grep --color=auto
[root@linux-node1 ~]# ps aux | grep
glance      1.7  6.4   ?        Ss   :   : /usr/bin/python2 /usr/bin/glance-registry
root        0.0  0.0     pts/    S+   :   : grep --color=auto 

　　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=
[root@linux-node1 ~]# tail - admin-openrc.sh
export OS_IMAGE_API_VERSION=
[root@linux-node1 ~]# tail - demo-openrc.sh
export OS_IMAGE_API_VERSION=

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.-x86_64-disk.img  --disk-format qcow2 --container-format bare  --visibility public --progress
[=============================>] %

| min_disk         |                                     |
| min_ram          |                                     |
| name             | cirros                               |
| owner            | 503b0eab0420454e909a46e476bf1ede     |
| protected        | False                                |
| size             |                              |
| status           | active                               |
| tags             | []                                   |
| updated_at       | --06T03::50Z                 |
| virtual_size     | None                                 |
| 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！
