使用VNC连接到Ubuntu 16.04远程桌面

Ubuntu 16.04自带桌面unity对VNC支持较差，需要在服务器上安装的gnome 3桌面

sudo apt-get install xinit 
sudo apt-get install gdm   #弹出选择窗口，选择gdm并回车
sudo apt-get update        #为下一条命令准备，否则下一条命令执行错误。 
sudo apt-get install ubuntu-desktop
apt-get install gnome-panel gnome-settings-daemon metacity nautilus gnome-terminal vnc4server

准备

如果你的系统中已经存在有vnc4server 或 tightvncserver，需要将它们移除

sudo apt remove -y vnc4server tightvncserver
sudo apt install -y git and devscripts
sudo apt install -y gnome-panel metacity

安装tigervncserver

git clone 下来，用源码方式安装

mkdir tigervnc
cd tigervnc
git clone https://github.com/TigerVNC/tigervnc
cd tigervnc/
git checkout 044e2b87da7121ef6cbd59e88b101d7d8e282896 -b 044e2b87da7121ef6cbd59e88b101d7d8e282896

编译和安装tigervnc

ln -s contrib/packages/deb/ubuntu-xenial/debian
sudo apt install -y $(grep Build-Depends: debian/control | sed -e 's/Build-Depends://g' -e 's/([^\)]*)//g' -e 's/,//g')
chmod a+x debian/rules
fakeroot debian/rules binary
cd ..
sudo dpkg -i *.deb || (sudo apt -f install -y; sudo dpkg -i *.deb)
cd ..

修改 ${HOME}/.xsessionrc

cat < ~/.xsessionrc
gnome-panel &
metacity &
EOF

如果存在/.xsession 文件就将其删除
rm ~/.xsession

配置和运行VNC Server

配置vnc的密码

$ vncpasswd
Password:
Verify:
Would you like to enter a view-only password (y/n)? n
Run vncserver. Remote access port is 5900 + display nummber.
A port of below example is 5901.

$ vncserver
New 'ubuntu-16:1 (hiroom2)' desktop is ubuntu-16:1
Starting applications specified in /home/hiroom2/.vnc/xstartup
Log file is /home/hiroom2/.vnc/ubuntu-16:1.log
Connect to vnc://:5901 with remote vnc client.
Input password and connection will be completed as below.

运行 XRDP 服务

Install and run xrdp.

sudo apt install -y xrdp
sudo systemctl enable xrdp
sudo systemctl restart xrdp

这时，在远程的PC上运行vncviewer之类的客户端就能访问服务器上的Ubuntu16.04

附录：vncserver 的常用管理命令

vncserver -list vncserver -kill  :2    #杀掉vnc　:2进程 
/usr/bin/vncserver -kill    :1		   #杀掉vnc　:1进程
vncserver -geometry 1920x1130		   #生成vnc桌面，并指定分辨率
