noVNC搭建

noVNC搭建

1. 环境准备

  1. Os: centos7.5
  2. 准备两台设备 192.168.17.176 和 192.168.17.177

2. 安装python环境

安装python3 在192.168.17.176操作如下

  1. 查看之前是否存在环境
python默认路径是 /usr/bin/，如有改动可以输入指令查看：# whereis python，这里可以看出我的服务最高指向python2.7
#  cd /usr/bin/
#  ll python*

lrwxrwxrwx. 1 root root    7 6月  10 2020 python -> python2
lrwxrwxrwx. 1 root root    9 6月  10 2020 python2 -> python2.7
-rwxr-xr-x. 1 root root 7216 8月   7 2019 python2.7
  1. 安装

因为我的centos7默认没有相关依赖和工具包，下载相关依赖和工具包：epel、pip、wget）最后通过wget从官网下载压缩包，xz编译，tar解压，进入python3.6.8，将其放到/usr/local目录下，然后make手动编译，接着安装依赖zlib、zlib-deve，最后下载默认没有python3-pip 命令并查看一下版本

# yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make
# yum -y install epel-release

# yum install python-pip

# pip install wget

# wget https://www.python.org/ftp/python/3.6.8/Python-3.6.8.tar.xz

# xz -d Python-3.6.8.tar.xz

# tar -xf Python-3.6.8.tar

#  cd Python-3.6.8

#  ./configure prefix=/usr/local/python3

#  make && make install

# yum install zlib zlib

# yum install zlib zlib-devel

# yum install -y python3-pip

# python3 -V

3. 安装vncserver

vncserver：只要被代理的机器都需要执行下面的安装，我们项目中是远程pe目标机器，所以每个pe目标机器就要安装好vncserver，这里把192.168.17.176 和 192.168.17.177都安装上，所以分别在这两个机器上执行下面的命令


systemctl stop firewalld

systemctl disable firewalld

yum install -y epel*

yum install tigervnc-server git -y

vncserver :1

# 此时会提示输入密码(就是vnc的登入密码)

4. 安装noVNC和websockify

首先将 vnc_listen = “0.0.0.0” 解禁，文件位置/etc/libvirt/qemu.conf noVNC和websockify 的安装只需要安装在一台机器上即可，这里选择 192.168.17.176

  1. 下载novnc
yum install -y git
git clone https://github.com/novnc/noVNC.git

# 下载完成如下所示

[root@localhost ~]# cd /root/noVNC/
[root@localhost noVNC]# ll

[root@localhost noVNC]#
  1. 下载使用websockify
[root@localhost ~]# cd /root/noVNC/utils
git clone https://github.com/novnc/websockify.git

# 下载完如下所示
[root@localhost noVNC]# cd utils/
[root@localhost utils]# ll

-rwxr-xr-x  1 root root      627 Dec 28 15:01 validate
drwxr-xr-x 10 root root     4096 Dec 28 15:16 websockify
[root@localhost utils]#

5. 创建态token文件便于一个端口访问多个vnc

cd websockify
mkdir token
vi ./token/vm1.conf

   文件内容 vm1: 192.168.17.176:5901
   
vi ./token/vm2.conf

   文件内容 vm2: 192.168.17.177:5901
   
# 如下所示
[root@localhost noVNC]# cd utils/
[root@localhost utils]# ll
total 82644
-rwxr-xr-x  1 root root      396 Dec 28 15:01 b64-to-binary.pl
-rwxr-xr-x  1 root root     5134 Dec 28 15:01 convert.js
-rwxr-xr-x  1 root root     3160 Dec 28 15:01 genkeysymdef.js
-rwxr-xr-x  1 root root     7279 Dec 28 15:01 novnc_proxy
drwxr-xr-x 18  501  501     4096 Dec 28 15:51 Python-3.6.8

-rw-r--r--  1 root root      538 Dec 28 15:01 README.md
-rwxr-xr-x  1 root root      911 Dec 28 15:01 u2x11
-rwxr-xr-x  1 root root      627 Dec 28 15:01 validate
drwxr-xr-x 10 root root     4096 Dec 28 15:16 websockify
[root@localhost utils]# cd websockify/
[root@localhost websockify]# cd token/
[root@localhost token]# ll
total 8
-rw-r--r-- 1 root root 25 Dec 28 16:15 vm1.conf
-rw-r--r-- 1 root root 25 Dec 28 16:27 vm2.conf
[root@localhost token]#

[root@localhost token]# pwd
/root/noVNC/utils/websockify/token
[root@localhost token]# cat vm1.conf
vm1: 192.168.17.176:5901
[root@localhost token]#

6. 启动noVNC


[root@localhost websockify]# cd ../
[root@localhost utils]# pwd
/root/noVNC/utils
[root@localhost utils]# ll
total 82644
-rwxr-xr-x  1 root root      396 Dec 28 15:01 b64-to-binary.pl

[root@localhost websockify]#

./run --token-plugin TokenFile --token-source ./token/ 4488

在浏览器输入http://192.16.17.176:8889/vnc.html?host=192.168.17.176&port=4488&path=websockify/?token=vm01就可以访问虚拟机了 其中http://192.16.17.176:8889/vnc.html中的ip为novnc的ip和端口，vnc.html为novnc的页面，还有一个精简版的页面vnc_lite.html 其中host 为websockify所在的服务器ip，port为其端口，path为访问路径，token 为我们刚才配置的token
