下载软件包：

下载慢和下载失败，直接手动用浏览器下载，再上传服务器。

wget -O noVNC-1.4.0.tar.gz https://github.com/novnc/noVNC/archive/refs/tags/v1.4.0.tar.gz
wget -O websockify-0.11.0.tar.gz https://github.com/novnc/websockify/archive/refs/tags/v0.11.0.tar.gz

解压软件包

tar -zxvf noVNC-1.4.0.tar.gz
tar -zxvf websockify-0.11.0.tar.gz -C noVNC-1.4.0/utils

启动vnc端口

在需要代理的vnc服务端启动vnc服务，或者是有现成的可连接的vncserver可忽略这一步

# 如果没安装vnc先安装vnc
vncserver :8

使用noVNC

sudo firewall-cmd --zone=public --add-port=6080/tcp --permanent
sudo firewall-cmd --reload
sudo firewall-cmd --zone=public --list-port
# start 
# ./noVNC-1.4.0/utils/novnc_proxy --vnc localhost:5908
# ./noVNC-1.4.0/utils/novnc_proxy --vnc 192.168.253.135:5908 --listen 6080
./noVNC-1.4.0/utils/novnc_proxy --vnc 192.168.253.135:5908 --listen 192.168.253.135:6080

在局域网使用浏览器访问：http://192.168.253.135:8080/vnc.html

其他用法

使用证书

cd noVNC-1.4.0/utils/
sudo yum install openssl -y
openssl req -new -x509 -days 365 -nodes -out self.pem -keyout self.pem # 按需填写
./noVNC-1.4.0/utils/novnc_proxy --vnc 192.168.253.135:5908 --listen 192.168.253.135:6080

在局域网使用浏览器访问：https://192.168.253.135:8080/vnc.html

安装numpy

sudo apt install python3-pip
# 临时替换清华源
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple some-package
pip install numpy

# 永久替换pip国内源
# python -m pip install --upgrade pip
# pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple
# 如果默认pip升级速度比较慢，使用清华镜像站零时升级
# python -m pip install -i https://pypi.tuna.tsinghua.edu.cn/simple --upgrade pip

使用numpy依赖，提升速度。
