可能很多人认为，horizon需要部署到controller节点上，其实openstack dashboard 在部署时不一定要部署到controller节点上，可以防止任何能连接云平台环境的地方。方法如下：
hosts文件 vi /etc/hosts 10.0.0.11 controller apache2环境 /etc/apache2/apache2.conf ServerName local_ip 安装horizon apt install openstack-dashboard 修改local_setting.py ... OPENSTACK_HOST = "controller" ... 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 # 这里要注意一下，如果在登录界面一直是登录失败，你要把v3换成v2!!! ... OPENSTACK_API_VERSIONS = { "identity": 3, "image": 2, "volume": 2, } ... OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "Default" # 如果没有特殊的域可以不加，官方是加了... ... # 巴拉巴拉一堆，按照官网上来就行，特别是要注意一下OPENSTACK_KEYSTONE_URL这个v3和v2的问题可能遇到的问题是：安装后，http://ip/horizon始终登陆上去，检查日志发现：Timeout when reading response headers from daemon process ‘horizon’: /usr/share/openstack-dashbo…
解决方法：
open the dashboard configuration file: vim /etc/apache2/conf-available/openstack-dashboard.conf
Add the following line to the configturation: WSGIApplicationGroup %{GLOBAL}
Reload the Apache service apache2 reload
最好是一个干净的系统（ubuntu16.04.2）

#:pip install -r requirements.txt --no-index --find-links=file:///home/ubuntu/horizon/depends等待安装完成…安装过程中可能遇到问题： error: command ‘x86_64-linux-gnu-gcc’ failed with exit status 1 解决方法： sudo apt-get install build-essential libssl-dev libffi-dev python-dev
执行命令： python manage.py collectstatic python manage.py compress –force python manage.py runserver 0.0.0.0:8000 试试能不能访问吧~~~
2.安装到隔离环境中(优先选择吧） * 进入到tools目录下 * python install_venv.py * 等到安装结束后，cd .. 执行 source .venv/bin/active * python manage.py runserver 0.0.0.0:8000
