How to install vnc on Linux: 1. Use the "yum install vnc vnc-server" command to install vnc; 2. Use the "yum install tightvnc-server" command to install "tigervnc-server".
#The operating environment of this tutorial: linux7.3 system, Dell G3 computer.
The first thing you need to know is what VNC is. VNC (Virtual Network Computing), a display screen sharing and remote operation software using RFB protocol. It is operating system agnostic and therefore works cross-platform. For example, you can use Windows to connect to a Linux computer through VNC Viewer.
The VNC system consists of a client, a server, and a protocol. The purpose of the server is to share the screen it is running on, and the server passively allows the client to control it.
Next, let’s talk about how to install VNC on Linux
1. First, check whether the VNC service is installed: Enter the command: rpm -qa | grep vnc, as shown in the figure below, it has been installed. If you do not proceed to the next step
1-1, install VNC: [root@localhost ~]# yum install vnc vnc-server
Install tigervnc-server: [root@localhost ~]# yum install tightvnc-server
Set the VNC password for the first time (remember the password here, you will need it when you come back to use VNC Viewer): [root@localhost ~]# vncserver, note that the password here must be at least The 6-digit
can also create multiple desktops by executing the vncserver command multiple times.
2. Configure the firewall.
If the firewall is not configured, client VNC will not be able to connect to Linux. In fact, VNC is just like our remote desktop. When you want to remote your own desktop, the first thing you need to do is to change some configurations on the firewall, right? Otherwise, the remote connection fails, and the reason is the same.
Configure firewall command:
[root@localhost ~]# iptables -I INPUT -p tcp –dport 5901 -j ACCEPT
[root@localhost ~]# iptables -I INPUT -p tcp –dport 5801 -j accept
In this place, two desktops are added. The corresponding relationship between the desktop and port is: desktop 1 corresponding to 5901, desktop 2 corresponding 5801, or you can set
3 to configure the desktop client. Enter the command: [root@localhost ~]# vi /root/.vnc/xstartup, the following interface will appear:
Press i in this interface to enter the editing state, and add the following content at the end:
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r ##HOME/.Xresources ] && xrdbHOME/.Xresources ] && xrdbHOME/.Xresources xsetroot -solid gray
vncconfig -iconic &
title “$VNCDESKTOP Desktop” &
gnome-session &
The modified interface is as shown in the figure:
The prerequisite for installing this step is that the Gnome desktop environment is installed in Linux
3 -1. Check whether the Gnome desktop environment is installed: enter the command: [root@localhost ~]#yum grouplist
or [root@localhost ~]#yum grouplist | more
If the gnome desktop environment is not installed, it will display:
If the desktop environment has been installed, it will display:
3-2. Install the gnome desktop graphical environment command (this process is relatively long and requires more things to install):
[root@localhost ~]# yum groupinstall “GNOME Desktop”
3-3, close and restart the service
Close the service: Vncserver –kill :1
Restart the service: vncserver :1
Use vncserver – list can check how many desktops are started
At this point, VNC has been installed. But nothing changed on Linux, and I still felt a little guilty. Just like when I used remote desktop for the first time, I finished the configuration, but I didn't know whether it was successful, so I needed to use another computer to connect to see if it could be successful.
4-1, install VNC Viewer on your computer:
4-2, open it and create a new connection, as shown in the figure:
4-3, find the VNC you created, as shown in the figure below, right-click the mouse and select Connect:
4-4, enter the password you entered when you created the VNC (if Forgot to see the introduction of 1-1, 1-1):
4-5, when this interface, select Continue:
and then succeed.
After each boot, you must manually start the VNC service by entering the command): vncserver or vncserver:1
