Installing VNC Remote Desktop on Centos VPS
In this tutorial we’ll install Gnome desktop and VNC server on Linux Centos Virtual Private Server (VPS). You need to install Gnome as the desktop for Linux VPS, this way you’ll get Graphical User Interface to manage your VPS or just use it as remote desktop. The VNC server is the remote control software that allows you to connect to the VPS Desktop.
1. Install Gnome Desktop, VNC Server and Xterm.
yum groupinstall gnome-desktop yum install vnc-server xterm
It will take some time to install the Gnome Desktop as it quite big packages.
2. Create a normal user.
Now we create a normal user that will be used as remote desktop user. In this example I use ‘vncuser’ but you can choose your own username, just make sure you replace ‘vncuser’ to your chosen username.
Setup the user password for vncuser
3. Login as vncuser and create VNC password.
Next we need to create password to access VNC server. This password is different with the password we create on step 2, the password on step 2 is for accessing SSH while this one is to accessing VNC remote desktop.
The command above will ask you to supply password to access the VNC server and create .vnc directory with passwd file inside it. To check whether passwd file is created run this command
After that return to root user by executing command
4. Creating xstartup script.
After we create the VNC user now we’ll create the VNC server xstartup script, we do this by starting and stopping the VNC server as root.
service vncserver start service vncserver stop
Now check if the xstartup script is created
That command should show these files: passwd <hostname>:1.log xstartup
5. Edit the default xstartup script to run Gnome desktop.
The default xstartup script looks like this:
#!/bin/sh # Uncomment the following two lines for normal desktop: # unset SESSION_MANAGER # exec /etc/X11/xinit/xinitrc [ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources xsetroot -solid grey vncconfig -iconic & xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" & twm &
You have to edit it so it looks like this:
#!/bin/sh ( while true; do xterm; done ) & # Uncomment the following two lines for normal desktop: unset SESSION_MANAGER exec /etc/X11/xinit/xinitrc [ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources xsetroot -solid grey vncconfig -iconic & xterm -geometry 1024x768 -ls -name "$VNCDESKTOP Desktop" & gnome-session &
6. Start the VNC server.
After finished editing the xstartup script run again the vncserver service
service vncserver start
You should see something like this:
7. Download Tight VNC client here: http://www.tightvnc.com/download.html
8. Connect to the VNC server
After you installed the Tight VNC client, run it and you’ll see this form:
On the VNC Server field, insert your VPS’ IP address followed with ‘:1’ and then click on Connect. You’ll be asked for a password, this is the password you created on step 3.
