OpenStack项目三--镜像服务安装（glance)

这是本人的一些学习笔记，如果有错误的地方或者更好的解决方法，欢迎提出！！

glance是openstack镜像服务，主要用来注册，登陆和检索虚拟机镜像

1.glance服务的安装

[root@openstack01 ~]# yum install -y openstack-glance

验证glance镜像服务是否正确安装

root@openstack01 ~]# cat /etc/passwd | grep glance
glance:x:161:161:OpenStack Glance Daemons:/var/lib/glance:/sbin/nologin
[root@openstack01 ~]# cat /etc/group | grep glance
glance:x:161:

2.修改glance镜像服务的配置文件

生成备份文件

[root@openstack01 ~]# cp /etc/glance/glance-api.conf /etc/glance/glance-api.conf.bak

去除空行注释，生成新的配置文件，方便修改

[root@openstack01 ~]# grep -Ev '^$|#' /etc/glance/glance-api.conf.bak > /etc/glance/glance-api.conf

打开去除空行注释的配置文件进行修改

[root@openstack01 ~]# cd /etc/glance/
[root@openstack01 glance]# vi glance-api.conf
[root@openstack01 glance]# cat glance-api.conf
[DEFAULT]
[cinder]
[cors]
[database]

[root@openstack01 glance]#

3.创建glance服务的数据库并授权

MariaDB [(none)]> create database glance;
Query OK, 1 row affected (0.001 sec)

MariaDB [(none)]> use glance;
Database changed
MariaDB [glance]> grant all privileges on glance.* to 'glance'@'localhost' identified by '000000';
Query OK, 0 rows affected (0.002 sec)

MariaDB [glance]> grant all privileges on glance.* to 'glance'@'%' identified by '000000';
Query OK, 0 rows affected (0.001 sec)

4.初始化数据库

[root@openstack01 ~]# su glance -s /bin/sh -c 'glance-manage db_sync'

进入数据库查看是否同步成功

5.glance组件初始化

导入环境变量

[root@openstack01 ~]# . admin-login

在openstack云计算平台中创建glance用户

[root@openstack01 ~]# openstack user create glance --password 000000 --domain default
+---------------------+----------------------------------+
| Field               | Value                            |
+---------------------+----------------------------------+
| domain_id           | default                          |
| enabled             | True                             |
| id                  | fbe3efdf54ed4700a7df58550b575778 |
| name                | glance                           |
| options             | {}                               |
| password_expires_at | None                             |

为用户glance分配管理员角色

[root@openstack01 ~]# openstack role add admin --project project --user glance

创建glance服务

[root@openstack01 ~]# openstack service create --name glance image
+---------+----------------------------------+
| Field   | Value                            |
+---------+----------------------------------+
| enabled | True                             |
| id      | abb8518a68bb439b8920054555e45aec |
| name    | glance                           |
| type    | image                            |
+---------+----------------------------------+

创建glance对外服务端点

[root@openstack01 ~]# openstack endpoint create --region RegionOne glance public http://openstack01:9292
+--------------+----------------------------------+
| Field        | Value                            |
+--------------+----------------------------------+
| enabled      | True                             |
| id           | 437b1d2a113444b681dd5ecb6e26e063 |
| interface    | public                           |
| region       | RegionOne                        |
| region_id    | RegionOne                        |
| service_id   | abb8518a68bb439b8920054555e45aec |
| service_name | glance                           |
| service_type | image                            |
| url          | http://openstack01:9292          |
+--------------+----------------------------------+

创建glance对内服务端点

[root@openstack01 ~]# openstack endpoint create --region RegionOne glance internal http://openstack01:9292
+--------------+----------------------------------+
| Field        | Value                            |
+--------------+----------------------------------+
| enabled      | True                             |
| id           | 8f946107e15c4500841243fd1be4291d |
| interface    | internal                         |
| region       | RegionOne                        |
| region_id    | RegionOne                        |
| service_id   | abb8518a68bb439b8920054555e45aec |
| service_name | glance                           |
| service_type | image                            |
| url          | http://openstack01:9292          |
+--------------+----------------------------------+

创建glance对管理员访问的端点

[root@openstack01 ~]# openstack endpoint create --region RegionOne glance admin http://openstack01:9292
+--------------+----------------------------------+
| Field        | Value                            |
+--------------+----------------------------------+
| enabled      | True                             |
| id           | ab7d4fe966a94b3784d217d2fe92b275 |
| interface    | admin                            |
| region       | RegionOne                        |
| region_id    | RegionOne                        |
| service_id   | abb8518a68bb439b8920054555e45aec |
| service_name | glance                           |
| service_type | image                            |
| url          | http://openstack01:9292          |
+--------------+----------------------------------+

6.启动glance服务

[root@openstack01 ~]# systemctl start openstack-glance-api
[root@openstack01 ~]# 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.

7.验证glance服务是否开启

[root@openstack01 glance]# ss -lntpu | grep 9292
tcp    LISTEN     0      128       *:9292                  *:*                   users:(("glance-api",pid=8837,fd=4),("glance-api",pid=8836,fd=4),("glance-api",pid=8835,fd=4),("glance-api",pid=8834,fd=4),("glance-api",pid=8822,fd=4))

至此，openstack的glance镜像服务配置完成
