 Dashboard 简介

Dashboard(horizon)是一个web接口,使得云平台管理员以及用户可以管理不同的openstack资源及服务。

 

安装和配置

以下配置在三个controller节点上完成:

# yum install openstack-dashboard -y
# vim /etc/openstack-dashboard/local_settings
# 以下列出需要修改的项:
OPENSTACK_HOST = "controller1"            # 修改为每个控制节点的主机名

ALLOWED_HOSTS = ['*', ]

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


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"

TIME_ZONE = "Asia/Shanghai"

 

安装完成:
    重启三个控制节点的服务:

# systemctl restart httpd.service memcached.service

 

配置dashboard的haproxy监听 80,整个高可用haproxy配置监听如下:
