之(五) Horizon安装

手动安装Openstack Mikita的第五部分: 用户界面Horizon安装.

这部分内容主要是对OpenStack Installation Guide for Red Hat Enterprise Linux and CentOS在Horizon这部分内容的实践总结.

Dashboard依赖于几个openstack的核心服务: Identity(Keystone), Image(Glance), Compute(Nove)以及网络服务. 其中网络服务可以由Neutron或者Nova-network提供. 一些独立的服务, 如Object Storage无法使用Dashboard.

我们在controller节点上部署Horizon服务.

1. 安装Horizon

[root@controller ~]# yum install openstack-dashboard -y

2. 配置Horizon

编辑 /etc/openstack-dashboard/local_settings 文件:

OPENSTACK_HOST = "controller"
ALLOWED_HOSTS = ['*', ]
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"

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

3. Restart the web server and session storage service

[root@controller ~]# systemctl restart httpd.service memcached.service

4. 验证

访问http://10.0.0.11/dashboard
