# 0x00 协议比较 #

> 参考 [远程桌面协议浅析（VNC/SPICE/RDP）][VNC_SPICE_RDP]

在进行SPICE操作之前，对目前常用的协议VNC/SPICE/RDP三种，进行简单的比较。

## 一、VNC ##

适用系统：windows、linux  
网络流量：较小，常用100k左右  
适用场景：主要用于linux的服务器的管理，由于无声音和usb传输，不满足于虚拟桌面的使用

# 安装
    yum install tigervnc-server
    #vnc服务器启动
    vncserver 
    #查看连接
    vncserver  -list   
    #修改访问密码
    vncpasswd    
    #关闭vncserver
    vncserver -kill :n

配置文件修改

#配置文件修改
    vim /etc/sysconfig/vncservers   
    # VNCSERVERS="2:myusername"   sessionnumber，用户名
    # VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -localhost" 
    VNCSERVERS="1:root" # display port and username
    VNCSERVERARGS[]="-geometry 800x600 -nolisten tcp -nohttpd"

## 二、SPICE ##

适用系统：linux  
网络流量：较大，正常使用10-20M  
适用场景：由于在色彩、音频和usb方面，适用于虚拟桌面，主要用于虚拟机的虚拟桌面应用  
使用：安装后，需要在虚拟机中配置，参考本人关于虚拟机的blog。

## 三、RDP ##

目前在windows上 rdp有两种，remote，remotefx  
适用系统：windows、linux  
网络流量：较小，正常使用100-200k左右  
适用场景：由于在色彩、音频、usb及本地磁盘映射方面较好，非常适用于虚拟桌面  
windows 使用：系统安装后即可使用。

#linux上安装rdesktop，用于linux访问windws远程桌面 
    #安装
    yum install rdesktop 
    #如需要在界面上使用需要安装
    yum install tsclient
    #使用命令行访问，-f 全屏 -a颜色 -c L 连接类型
    rdesktop -f -a  119.0.0.100:

#使用rdp协议访问linux
    yum install xrdp 
    #启动xrdp服务
    xrdp

# 0x01 环境说明 #

*  宿主机：Windows10 + VMware Workstation 16
 *  节点：控制节点controller，计算节点1、计算节点2
 *  虚拟机操作系统：CentOS8.3-x86\_64-Minimal2011，[环境说明与准备][Link 1]
 *  OpenStack版本：Victoria
 *  Spice软件版本：

安装

yum makecache
    yum install -y spice-server spice-protocol openstack-nova-spicehtml5proxy

手动安装spice-html5，[快速下载][Link 2]

#yum install -y spice-html5
    wget https://www.spice-space.org/download/spice-html5/spice-html5-0.1.1-1.fc18.noarch.rpm
    rpm -ivh spice-html5-0.1.1-1.fc18.noarch.rpm

### 2.控制节点nova.conf ###

> ①`[default]`指定vnc\_enabled=false，否则即使配置了spice，系统也仍然使用vnc  
> ②一定要注释掉原vnc配置

*  `[default]`

[default]
    vnc_enabled=false

*  **注释掉原vnc相关配置**

[vnc]
    #enabled = true
    #server_listen = $my_ip
    #server_proxyclient_address = $my_ip

*  `[spice]`

[spice]
    enabled=True
    keymap=en-us
    server_listen=0.0.0.0
    server_proxyclient_address=$my_ip
    html5proxy_host=0.0.0.0
    html5proxy_port=6082
    html5proxy_base_url=http://10.0.0.11:6082/spice_auto.html

### 3.停止novncproxy并取消开机启动 ###

systemctl stop openstack-nova-novncproxy.service
    systemctl disable openstack-nova-novncproxy.service

### 4.启用spicehtml5proxy并配置开机自启 ###

systemctl enable openstack-nova-spicehtml5proxy.service
    systemctl start openstack-nova-spicehtml5proxy.service
