此文档是在本来安装了计算节点的机器上实验的。

cd /home/github

1.取得源代码：

  git clone  https://github.com/openstack/horizon.git

备份一份

mkdir /home/src

pwd

/home

cp -r /github/horizon   /src

cd /home/src/horizon

2.install the prerequisite packages：
    apt-get install nodejs
   

3. create a virtual environment:
     python tools/install_venv.py          时间很长
     注意，1.运行前先修改一下tools/install_venv.py，在def create_virtualenv函数里，指定安装pip的版本为1.1，
               if not run_command([WITH_VENV, 'easy_install', 'pip==1.1']).strip():
              

                2.安装virtual environment时经常出现timeout错误，因此可以修改tools/install_venv.py文件中的def pip_install函数，增加default-timeout参数，run_command(['tools/with_venv.sh', 'pip','--default-timeout=1800', 'install', '--upgrade'] + list(args),redirect_output=False) 。
       另外，尽量运行python tools/install_venv.py安装虚拟环境，如果失败，下次安装会接着失败处继续安装

安装成功会提示：

Horizon development environment setup is complete.

To activate the virtualenv for the extent of your current shell session you
can run:

$ source .venv/bin/activate

官方文档： 

Note

If you would like to run commands without the prefix of tools/with_venv.sh you may source your environment directly. This will remain active as long as your shell session stays open:

> source .venv/bin/activate

 例如使用：

> tools/with_venv.sh ./manage.py runserver

Alternately specify the listen IP and port:

> tools/with_venv.sh ./manage.py runserver 0.0.0.0:8080

source .venv/bin/activate
就可以直接输入命令了

python manage.py runserver 0.0.0.0:8080

注意：0.0.0.0需要修改为ip地址

4. unit tests:
    ./run_tests.sh                    时间很长

最后提示：

Horizon development environment setup is complete.

To activate the virtualenv for the extent of your current shell session you
can run:

$ source .venv/bin/activate

5.   cp openstack_dashboard/local/local_settings.py.example  openstack_dashboard/local/local_settings.py

6.运行

python manage.py runserver 192.168.240.101:8080   

 输入用户名admin  密码openstack 提示认证失败  An error occurred authenticating. Please try again later.

在运行runserver 服务后，在服务器的后台就运行了一个服务。
在本地就可以通过浏览器中输入192.168.1.125:8080
用户名admin
密码openstack登录

浏览器一定要使用支持html5的浏览器，推荐使用最新firefox和chrome ,IE9兼容性还是很不好。
