NOVNC 安裝與啟動

1. 安裝 novnc python-websockify 套件

   [root@dyw219 ~]# yum install novnc python-websockify
   

2. 切換工作目錄到 novnc。

   [root@dyw219 ~]# cd /usr/share/novnc/
   

3. 執行 websockify，出現錯誤訊息。

   [root@dyw219 novnc]# websockify --web /usr/share/novnc 6080 163.17.27.219:5902 
   Warning: could not find self.pem
   Starting webserver and WebSockets proxy on port 6080
   Traceback (most recent call last):
     File "/usr/bin/websockify", line 5, in <module>
       from pkg_resources import load_entry_point
   ImportError: No module named pkg_resources
   Failed to start WebSockets proxy
   

4. 下載 ez_setup.py 程式。

   [root@dyw219 novnc]# curl -O https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py
     % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

5. 執行 ez_setup.py 程式，出現錯誤訊息。

   [root@dyw219 novnc]# python ez_setup.py
   .......

   ERROR: IPython requires Python version 2.7 or 3.3 or above.
   error: Setup script exited with 1
   

6. 執行 easy_install-2.6，升級 pip。若使用 python2.7，則執行 easy_install。

   [root@dyw219 novnc]# easy_install-2.6 --upgrade pip
   

7. 再執行 websockify 程式，雖已啟動，但有缺 numpy 模組的警告訊息。

   [root@dyw219 novnc]# websockify --web /usr/share/novnc 6080 163.17.27.219:5902
   WARNING: no 'numpy' module, HyBi protocol is slower or disabled

     - No SSL/TLS support (no cert file)
     - proxying from :6080 to 163.17.27.219:5902
   

8. 安裝 numpy 模組。

   [root@dyw219 novnc]# yum install numpy
   

9. 再執行 websockify 程式，缺 numpy 模組的警告訊息已不見。

   [root@dyw219 novnc]# websockify --web /usr/share/novnc 6080 163.17.27.219:5902
