OpenStack部署之添加Dashboard服务六

Dashboard服务安装在控制节点(10.20.9.13)操作

1.安装相关包

[root@Controller-Node ~]# yum install openstack-dashboard

2.编辑/etc/openstack-dashboard/local_settings文件，修改以下配置

 注：以下的配置大部分在原配置文件中都包括，修改即可，不要直接添加

1.>配置dashboard在控制节点上使用OpenStack服务：

OPENSTACK_HOST = "10.20.9.13"

2.>允许主机连接到dashboard, *表示允许所有主机连接dashboard，在生产环境中不建议这样做。

ALLOWED_HOSTS = ['*',]

3.> 配置memcached存储服务：

SESSION_ENGINE='django.contrib.sessions.backends.cache'

CACHES={

　'default':{

　'BACKEND':'django.core.cache.backends.memcached.MemcachedCache',

　'LOCATION':'10.20.9.13:11211',

　}

　}

4.> 启用认证API版本3

OPENSTACK_KEYSTONE_URL = "http://%s:5000/v2.0" % OPENSTACK_HOST

5.> 启用域支持：

OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT=True

6.> 配置API版本：

OPENSTACK_API_VERSIONS = {
    "identity": 3,
    "image": 2,
    "volume": 2,
    "compute": 2,
}

7.> 配置default作为用户通过dashboard创建的默认的域：

OPENSTACK_KEYSTONE_DEFAULT_DOMAIN="default"

8.> 配置user作为用户创建的默认的角色：

OPENSTACK_KEYSTONE_DEFAULT_ROLE="user"

3.启web服务器以及会话存储服务

# systemctl restart httpd.service memcached.service

如果启动都没问题，就可以访问OpenStack dashbaord 服务.

访问地址：http://10.20.9.13/dashboard/admin/

 登录后页面可以正常访问，但是点击概况后右上角出现了错误：Invalid service catalog service: compute的异常信息. 

既然遇到错误就查看原因解决吧.

查看日志# tail -100f /var/log/httpd/error_log 发现报的也是这个，那就百度吧。。。

查看catalog变量信息,发现多创建了一个nova服务，但是没有数据，两个都删除，然后重新创建nova.

删除nova，命令自行 openstack service -h 查看.

[root@Controller-Node httpd]# openstack service delete 6f1d48bd8f5a40cc95c63487869caf78

[root@Controller-Node httpd]# openstack service delete b3db11e1135f40d6864650dc0ccf798d

重新创建 nova 服务实体：可以参考 OpenStack部署之添加Compute 服务四.

 openstack service create --name nova \
  --description "OpenStack Compute" compute
  
[root@Controller-Node httpd]#  openstack service create --name nova \
>   --description "OpenStack Compute" compute
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | OpenStack Compute                |
| enabled     | True                             |
| id          | 6f56e4c3acd542e7b7a3383e8b33e3db |
| name        | nova                             |
| type        | compute                          |
+-------------+----------------------------------+
[root@Controller-Node httpd]# 

重新创建计算服务API端点：

$ openstack endpoint create --region RegionOne \
  compute public http://10.20.9.13:8774/v2/%\(tenant_id\)s
 
$ openstack endpoint create --region RegionOne \
  compute internal http://10.20.9.13:8774/v2/%\(tenant_id\)s

$ openstack endpoint create --region RegionOne \
  compute admin http://10.20.9.13:8774/v2/%\(tenant_id\)s

重启服务：

[root@Controller-Node httpd]#systemctl restart httpd

再次访问页面 http://10.20.9.13/dashboard/admin/，页面一切正常了。ok。。

 

 查看catalog也正常了。

[root@Controller-Node httpd]# openstack catalog list
