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:
