How to install vncserver in Ubuntu 20.04

Ubuntu 20.04 has been officially released in April 2020. Today, I officially installed a mirror system and installed vncserver in the system to facilitate remote graphical management and use. The steps to install vncserver are as follows:

Step 1: Install the desktop environment and VNCServer

#updateapt update
#Install the desktop environment sudo apt install xfce4 xfce4-goodies
#Install vncserver
apt install tightvncserver
#Start vncserver
vncserver

Then follow the prompts, enter the password you used to log in to vncserver and enter it again to confirm.

After logging in remotely, I found that the desktop was gray. It seems that you also need to configure the vncserver environment:

Step 2: Configure vncserver parameters

#Close vncserver: 1 window vncserver -kill: 1
#Back up the original configuration file mv ~/.vnc/xstartup ~/.vnc/xstartup.bak
#Edit the new configuration file vim ~/.vnc/xstartup

Update the xstartup file to the following:

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

Then set the permissions for the document

chmod +x ~/.vnc/xstartup

Then restart vncserver to connect to the graphical interface. The screenshot is as follows:

You can see that the graphical interface has appeared. However, this is currently an insecure connection method. If security is a concern, further configuration is still required.

Enter in the remote host terminal:

ssh -L 59000:localhost:5901 -C -N -l root server_ip

Where server_ip is replaced by your remote host IP address.

Then use putty. Other settings are similar to normal ssh settings, except that you need to set up an ssh tunnel. The specific settings are shown in the figure below:

Enter 5901 in the source port and 127.0.0.1:5901 in the destination, then click the Add button to add the effect shown in the figure above.

Then first use ssh to log in to the remote host locally, and then enter 127.0.0.1:1 in the client such as vncviewer to log in.
