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": ,
    "image": ,
    "volume": ,
}

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：
