openstack VNC无法使用

一 问题现象

二 问题分析分析日志：openstack-nova-novncproxy并没有启动

手动执行启动脚本：/usr/bin/nova-novncproxy --web /usr/share/novnc/

[root@controller0 ~]# /usr/bin/nova-novncproxy --web /usr/share/novnc/
Traceback (most recent call last):
File "/usr/bin/nova-novncproxy", line 10, in <module>
sys.exit(main())
File "/usr/lib/python2.6/site-packages/nova/cmd/novncproxy.py", line 87, in main
wrap_cmd=None)

上网搜索：File "/usr/lib/python2.6/site-packages/websockify/websocketproxy.py", line 231, in __init__ 关键字获得相关信息http://blog.csdn.net/ycl146/article/details/62043704
三 错误原因websockify版本太低，升级websockify版本即可。
四 解决方法在控制节点执行如下命令pip install websockify==0.5.1
