# 一、horizon 介绍： #

理解 horizon

**Horizon 为 Openstack 提供一个 WEB 前端的管理界面 (UI 服务** )通过 Horizone 所提供的 DashBoard 服务 , 管理员可以使用通过 WEB UI 对 Openstack 整体云环境进行管理 , 并可 **直观看到各种操作结果与运行状态。**

** **

# 二、horizon ——web界面部署 #

点进Dashboard——Install and configure

1）安装dashboard

yum install openstack-dashboard

2)修改/etc/openstack-dashboard/local\_settings 配置文件

一共8处

OPENSTACK_HOST = "controller" SESSION_ENGINE = 'django.contrib.sessions.backends.cache' CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache', 'LOCATION': 'controller:11211', } }

![复制代码][copycode.gif]

OPENSTACK\_KEYSTONE\_URL = "http://%s:5000/v3" % OPENSTACK\_HOST

OPENSTACK\_KEYSTONE\_MULTIDOMAIN\_SUPPORT = True

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

OPENSTACK\_KEYSTONE\_DEFAULT\_DOMAIN = "Default"

OPENSTACK\_KEYSTONE\_DEFAULT\_ROLE = "user"

![复制代码][copycode.gif]

OPENSTACK_NEUTRON_NETWORK = { ... 'enable_router': False, 'enable_quotas': False, 'enable_distributed_router': False, 'enable_ha_router': False, 'enable_lb': False, 'enable_firewall': False, 'enable_vpn': False, 'enable_fip_topology_check': False, }

![复制代码][copycode.gif]

ALLOWED\_HOSTS = \['horizon.example.com', 'localhost',"\*"\]

3）重启httpd和memcached服务

systemctl restart httpd.service memcached.service

4）网页浏览ip加/dashboard

第一次缓存到数据库所有可能会慢点。
