仪表盘服务（DashboardHorizon）部署

仪表盘服务（Dashboard/Horizon）部署

OpenStack推出了一个名为Horizon的项目，它提供了图形化的操作界面来使用OpenStack云计算平台。
Horizon中主要提供了一个Web前端控制台，该控制台软件被称为Dashboard。

1、安装Dashboard软件包

在计算节点安装Dashboard软件包。

2、修改Horizon配置文件

# 修改Horizon配置文件
# 修改Horizon配置文件
[root@compute opt]# vi /etc/openstack-dashboard/local_settings
# 控制节点位置
OPENSTACK_HOST = "controller"
OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST
# 启用对多域的支持
OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True
# 配置API版本
OPENSTACK_API_VERSIONS = {
    "identity": 3,
    "image": 2,
    "volume": 3
}
# 配置通过仪表盘创建的用户默认域为Default
OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "Default"
# 配置通过仪表盘创建的用户默认角色为user
OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"

# 修改配置二层网络
OPENSTACK_NEUTRON_NETWORK = {
    'enable_auto_allocated_network': False,
    'enable_distributed_router': False,
    'enable_fip_topology_check': False,
    'enable_ha_router': False,
    'enable_ipv6': False,
    'enable_quotas': False,
    'enable_rbac_policy': False,
    'enable_router': False,

    'default_dns_nameservers': [],
    'supported_provider_types': ['*'],
    'segmentation_id_range': {},
    'extra_provider_types': {},
    'supported_vnic_types': ['*'],
    'physical_networks': [],
}
# 配置时区
TIME_ZONE = "Asia/Shanghai"

# 允许从任意主机访问
ALLOWED_HOSTS = ['*']

# 配置使用缓存服务
CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
        'LOCATION': 'controller:11211',
    },
}
SESSION_ENGINE = 'django.contrib.sessions.backends.cache'

3、重建Apache下Dashboard配置文件

Dashboard是一个Web应用，必须运行在Apache这样的WEB服务器上，因此要设置让Apaceh知道如何运行该服务。

# 进入Dashboard网站目录
[root@compute opt]# cd /usr/share/openstack-dashboard/
[root@compute openstack-dashboard]# ls
manage.py  manage.pyc  manage.pyo  openstack_dashboard  static
# 编译生成Dashboard的WEB服务文件
[root@compute openstack-dashboard]# python manage.py make_web_conf --apache > /etc/httpd/conf.d/openstack-dashboard.conf
[root@compute openstack-dashboard]# cat /etc/httpd/conf.d/openstack-dashboard.conf 

<VirtualHost *:80>

    ServerAdmin webmaster@openstack.org
    ServerName  openstack_dashboard

    DocumentRoot /usr/share/openstack-dashboard/

    LogLevel warn
    ErrorLog /var/log/httpd/openstack_dashboard-error.log
    CustomLog /var/log/httpd/openstack_dashboard-access.log combined

    WSGIScriptReloading On
    WSGIDaemonProcess openstack_dashboard_website processes=3
    WSGIProcessGroup openstack_dashboard_website
    WSGIApplicationGroup %{GLOBAL}
    WSGIPassAuthorization On

    WSGIScriptAlias / /usr/share/openstack-dashboard/openstack_dashboard/wsgi.py

    <Location "/">
        Require all granted
    </Location>

    Alias /static /usr/share/openstack-dashboard/static
    <Location "/static">
        SetHandler None
    </Location>
</Virtualhost>
#这样就实现了在Apache的web服务配置目录下生成一个配置文件。

4、建立策略文件软连接

在/etc/openstack-dashboard/目录下保存了一些Dashboard与其他组件交互时的默认策略。

# 查看交互默认策略
[root@compute ~]# cd /etc/openstack-dashboard/
[root@compute openstack-dashboard]# ls
cinder_policy.json  keystone_policy.json  neutron_policy.json  nova_policy.json
glance_policy.json  local_settings        nova_policy.d

# 将这些策略链接到Dashboard项目中，让策略生效
[root@compute openstack-dashboard]# ln -s /etc/openstack-dashboard /usr/share/openstack-dashboard/openstack_dashboard/conf
[root@compute openstack-dashboard]# ll /usr/share/openstack-dashboard/openstack_dashboard/
