更新：5月4日；添加noVNC的配置
1配置
1.1创建配置文件：
[ugyn@cc ~]$ vim install/horizon-2012.1/openstack_dashboard/local/local_settings.py
将示例配置文件拷入其中，修改数据库信息，在USE_SSL = False下添加一行：
SECRET_KEY = 'elj1IWiLoWHgcyYxVLj7cMrGOxWl0'随意修改部分字符即可。
将该文件拷贝一份到horizon安装目录：
[ugyn@cc ~]$ sudo cp install/horizon-2012.1/openstack_dashboard/local/local_settings.py /usr/lib/Python2.6/site-packages/horizon-2012.1-py2.6.
egg/openstack_dashboard/local/local_settings.py
1.2为httpd创建horizon配置文件
[ugyn@cc ~]$ sudo vim /etc/httpd/conf.d/horizon.conf
内容如下：
<VirtualHost *:80> WSGIScriptAlias / /usr/lib/python2.6/site-packages/horizon-2012.1-py2.6.egg/openstack_dashboard/wsgi/django.wsgi WSGIDaemonProcess horizon user=apache group=apache processes=3 threads=10 home=/usr/lib/python2.6/site-packages/horizon-2012.1-py2.6.egg SetEnv APACHE_RUN_USER apache SetEnv APACHE_RUN_GROUP apache WSGIProcessGroup horizon DocumentRoot /usr/lib/python2.6/site-packages/horizon-2012.1-py2.6.egg/.blackhole/ Alias /media /usr/lib/python2.6/site-packages/horizon-2012.1-py2.6.egg/openstack_dashboard/static <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /usr/lib/python2.6/site-packages/horizon-2012.1-py2.6.egg/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> ErrorLog /var/log/httpd/horizon_error.log LogLevel warn CustomLog /var/log/httpd/horizon_access.log combined </VirtualHost> WSGISocketPrefix /var/run/httpd
WSGISocketPrefix /var/run/httpd创建目录：mkdir /usr/lib/python2.6/site-packages/horizon-2012.1-py2.6.egg/.blackhole
1.3初始化数据库：
[ugyn@cc ~]$ install/horizon-2012.1/manage.py syncdb

2运行
重启httpd
[ugyn@cc ~]$ sudo service httpd restart
Stopping httpd: [ OK ]
Starting httpd: Warning: DocumentRoot [/usr/lib/python2.6/site-packages/horizon-2012.1-py2.6.egg/.blackhole/] does not exist
httpd: apr_sockaddr_info_get() failed for cc.sigsit.org
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
[ OK ]
关闭nova-api并重新运行
3测试
登录界面：
镜像列表：
创建实例：
4配置noVNC
4.1配置
vnc的配置在nova.conf文件中，在文件的后面已经添加了以下内容：
# NOVNC CONSOLE
novncproxy_base_url=http://10.61.2.88:6080/vnc_auto.html
xvpvncproxy_base_url=http://10.61.2.88:6081/console
vncserver_proxyclient_address=10.61.2.88
vncserver_listen=10.61.2.88
这里vncserver_listen的值在计算节点上时应配置成计算节点的ip，不然会报错libvirtError: operation failed: failed to retrieve chardev info in qemu with 'info chardev'而无法启动实例。
4.2启动nova-consoleauth
noVNC要通过nova-consoleauth来进行token的验证，且nova-all不启动nova-consoleauth，因此我们得另外启动nova-consoleauth
4.3安装noVNC代理
essex版不包含nova-novncproxy，我们得自己下载安装
地址：https://github.com/cloudbuilders/noVNC
解压至：/var/lib/noVNC
请确定已经安装了numpy，如果没有请运行：
sudo yum --enablerepo=iso --disablerepo=base,updates,extras install numpy
进入目录：/var/lib/noVNC
运行：utils/nova-novncproxy --flagfile=/etc/nova/nova.conf
这里一定要进行目录/var/lib/noVNC，运行时会当前目录做为根目录，否则路径就不对了
这样就可以了，但在 我这里的运行结果并不理想，有时候就只有一个黑框看不到东西，有时能看到内容，但无法鼠标，键盘输入。
