novnc安装教程

适配于centos7

1.安装vncserver

# stop selinux and iptables
setenforce
systemctl stop firewalld
systemctl disable firewalld

# install vncserver and git
yum install -y epel*
yum install tigervnc-server git -y
vncserver :1
# 此时会提示输入密码

2、安装novnc

 yum install -y git
git clone https://github.com/novnc/noVNC.git   //从GitHub 克隆

cd ./noVNC/utils/
git clone https://github.com/novnc/websockify.git
openssl req -new -x509 -days 365 -nodes -out self.pem -keyout self.pem
cd noVNC
./utils/launch.sh --vnc localhost:

     WebSocket server settings:
  - Listen on :
  - Web server. Web root: /vnc/noVNC
  - No SSL/TLS support (no cert file)
  - proxying from : to 192.168.1.32:

    Navigate to this URL:                  //跳转

        http://compute2:6080/vnc.html?host=compute2&port=6080

访问 http://localhost:6080/vnc.html

3、以上操作只能连接本机，高级用法

cd novnc
mkdir token
cat token.conf
    abc123: 192.168.1.32:
    abc456: 192.168.1.32:
    abc123: 192.168.1.33:
pwd
/root/noVNC/token

代理服务器执行
yum install -y screen         //新开screen 窗口输入、防止被打断
screen -R vnc                 //这里会进入一个新的会话窗口
./utils/websockify/websockify.py --web ./ --target-config=./token/token.conf
ctrl a +d 退出screen

http://192.168.1.202:8787/vnc.html?path=?token=abc123    //这里的token改为对应的token

4、速度慢，安装numpy

 cd /usr/local/src
wget http://jaist.dl.sourceforge.net/project/numpy/NumPy/1.8.2/numpy-1.8.2.tar.gz
tar xvf numpy-1.8.
cd numpy-1.8.               ##yum install python-devel 缺少什么就装一下
python setup.py install

5、查看是否安装成功

>>> from numpy import *
>>> eye()
array([[ .,  .,  .,  .],
       [ .,  .,  .,  .],
       [ .,  .,  .,  .],
       [ .,  .,  .,  .]])
>>>
