That's why we're chosing TigerVNC , which works exactly like that by starting parallel sessions of the machine desktop environment Gnome , KDE or other GUI on the connecting client VNC desktop: this basically means that a standalone virtual desktop will be created for each separate connection - which is precisely what we want.

The first thing to do is to install the tigervnc-server software package by opening a terminal session and issuing the following command with root privileges:. Right after that, you should create a dedicated VNC user to connect with with a dedicated password.

Once you created the vncuser and its login password, you also need set a VNC-unique password for that user. This can be done with the following command:. That "1" which we put in the new filename is the display number that will be used for that specific service instance. Right after the copy, you need to edit the new file using vi , nano or another text editor and replace the [USER] placeholder with the name of the user created a short while ago vncuser in our scenario.

Here's how the file should look after the update minus the long commented part at the beginning :. As soon as you do that, you can reload the VNC daemon and start the vncserver 1 with the commands below:. Before proceeding, it could be wise to check if the service is running by issuing the systemctl status command Another check you can do before trying to connect to our server is to take a look to the active network sockets using the ss command: if everything works properly, you should see a VNC server running and listening on port TCP Since our VNC service is listening to port TCP , you need to be sure that such port is open and accessible by external clients: therefore, if you have a firewall installed, you should create an appropriate rule to allow VNC clients to connect.

How many ports to open will depend by how many instances of VNC servers you'll going to need: in our scenario, you only made 1, therefore you only need to open the first allocated VNC port: TCP , just like we said. Here's the command to open that port on firewalld :.

Needless to say, you can also restrict that port for specific groups, IP addresses, network cards or other simple or complex firewall rules: that's entirely to you, depending on your network environment's configuration and how much you want to be safe. If you already have GNOME, KDE or other desktop environments installed on our system you can skip this step, otherwise you'll need to add one: the TigerVNC server will start a parallel instance of a given desktop environment for each login session, meaning that we need to have one - otherwise it won't work.

Don't misunderstand us here, GNOME works fine as well, but it's quite space-and-resource-intensive: if you want to save resources on your server machine, Xfce would arguably be a better choice. If you've chosen to use Xfce , you'll also need to change the file to execute when the VNC session starts. Just remember to specify the port TCP if you've followed our guide. In case your client is unable to establish a working VNC connection, you need to checkup the following:. Here vncserver I have this service unit file from tigervnc-server In this example the user will be root.

Next similarly to install and configure vnc server on CentOS 7 for normal user, we will modify the other configuration file for " deepak " user. In this method we don't have any special handling for root and normal user to be able to use vnc server. I have this unit file with tigervnc-server Below is a sample unit file for vncserver service.

Next to complete the steps to install and configure vnc server we must start the vnc server service. To start or enable the service, specify the display number directly in the command. Run the firewall configuration tool and add TCP port to allow incoming connections to the system. Restart vnc server service after making any changes in configuration file. Similarly to enabling the vncserver service, you can disable the automatic start of the service at system start:.

Or, when your system is running, you can stop the service by issuing the following command as root:.

I have a problem when I set up vnc user accounts for any user other than root. How can I start the non-root user vnc services? This is weird, have you followed this article to configure vnc or do you have a different configuration? Hi, thanks for the reply. Yes I followed the steps as shown above exactly and set the password for each user using the user shell but the error is persistent.

Hi Anil, based on your comment I tried to reproduce the error and looks like with newer tigervnc-server, the steps of configuration has changed.
