1.Xfce图形化介绍：

桌面环境使用Xfce，它是一个精简的轻量化桌面，与Gnome和KDE相比更小巧，并且界面美观、对用户友好，适合云服务器远程连接场景下使用。

2.安装图形化

更新yum

$ yum update -y

查是否有xfce

#若无xfce，需要安装epel-release
[root@JRT ~]# yum grouplist

$ yum groupinstall xfce

安装完成xfce之后进入桌面 

$ systemctl isolate graphical.target

3.安装vnc远程工具

服务端

安装vncserver

[root@ecs-bd8d ~]# yum install -y tigervnc-server

Complete!
[root@ecs-bd8d ~]#

vim ~/.vnc/xstartup

#!/bin/sh
xrdb $HOME/.Xresources
startxfce4 &

设置启动级别

# systemctl set-default graphical.target　　#graphical.target相当于level5，multi-user.target相当于level3

配置root用户实例

#root用户，服务名是vncserver@:1.service：
cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:1.service

修改拷贝过来的模板配置文件，主要是[Service]部分 

# vim /etc/systemd/system/vncserver@\:1.service
[Service]
Type=forking
User=root
# Clean any existing files in /tmp/.X11-unix environment
ExecStartPre=-/usr/bin/vncserver -kill %i
ExecStart=/sbin/runuser -l root -c "/usr/bin/vncserver %i"
PIDFile=/root/.vnc/%H%i.pid
ExecStop=-/usr/bin/vncserver -kill %i

修改vncserver密码

#修改密码
#密码：长度为6~8个字符。超过8个字符的密码将自动截断。请牢记该密码，VNC Viewer连接云服务器时会使用。
#验证密码：再次输入密码。
#是否创建仅查看密码：使用仅查看密码登录的用户将无法使用鼠标或键盘控制云服务器。此处输入“n”。
 vncpasswd    #root用户实例的vnc密码

启动服务 

[root@ecs-bd8d ~]#systemctl daemon-reload
[root@ecs-bd8d ~]#systemctl start vncserver@:1.service
[root@ecs-bd8d ~]# netstat -nltp |grep vnc
tcp        0      0 0.0.0.0:5901            0.0.0.0:*               LISTEN      772/Xvnc            
tcp        0      0 0.0.0.0:6001            0.0.0.0:*               LISTEN      772/Xvnc            
tcp6       0      0 :::5901                 :::*                    LISTEN      772/Xvnc            
tcp6       0      0 :::6001                 :::*                    LISTEN      772/Xvnc

客户端

下载vnc view

#安装后，客户端不会生成桌面快捷方式，需要安装时指定目录
VNC Viewer下载地址：https://www.realvnc.com/en/connect/download/viewer/

连接

1.打开VNC Viewer软件，新建连接,依次点击File----New connection...,在弹出来的连接属性窗口中的VNC Server输入vnc服务器的ip和端口，注意端口就是刚才查到的那个5901。Name项就随便随便写了，仅仅是个vnc连接工具的快捷方式名称而已。

2.双击刚才实例，输入密码，连接即可。
