ubuntu 直接部署

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/hosts10.0.0.11 controller
  • apache2环境
/etc/apache2/apache2.confServerName 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

开发准备

  • 最好是一个干净的系统(ubuntu16.04.2)

  • 阿里云的源

  • pip 准备
  • 安装pip
    注意:最好别用apt-get 的方法,这个方法功能可能不全(版本老)
#: wget https://bootstrap.pypa.io/get-pip.py  --no-check-certificate#: python get-pip.py
  • 修改pip源
在主目录下创建.pip文件夹mkdir ~/.pip然后在该目录下创建pip.conf文件编写如下内容:[global]trusted-host =  pypi.douban.comindex-url = http://pypi.douban.com/simple
  • 获取horizon包
git clone  https://github.com/openstack/horizon.git
  • 下载依赖文件(下载文件,方便以后使用,避免移植开发环境重复下载)
#:cd horizon#:mkdir depends#:cd depends#:pip download -r ../requirements.txt...

* 有两种方式进行安装依赖,一种是直接安装到python大环境中,一种是装安装到隔离环境中(推荐到隔离环境中)***
1.直接安装离线包—不推荐

#: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
