Centos 7 Installation VNC step

VNC allows Linux systems to access Linux desktops like Remote Desktop access in Windows. This document configures the machine to operate in a CentOS 7 HP server Environment of the Xingning Network Information Center.

First try the server with VNC.

[Root@wic ~]# rpm-q Tigervnc tigervnc-server

If not installed, it will appear directly.

Package tigervnc are not installedpackage Tigervnc-server are not installed

If you do not have the X-windows desktop installed, install Xwindows first

[Root@wic ~]# yum Check-update[root@wic ~]# yum groupinstall "X Window System" [Root@wic ~]# yum Install gnome-classic-sess Ion gnome-terminal nautilus-open-terminal control-center Liberation-mono-fonts[root@wic ~]# unlink/etc/systemd/ System/default.target[root@wic ~]# ln-sf/lib/systemd/system/graphical.target/etc/systemd/system/default.target[ Root@wic ~]# reboot

The first step is to install the VNC packages:

[Root@wic ~]# Yum Install tigervnc-server-y

The second step, modify the configuration information, create a folder under/etc/systemd/system/Vncserver@:1.service example config file from/lib/systemd/system/ Vncserver@.service copy into the inside

[Root@wic ~]# Cp/lib/systemd/system/vncserver@.service/etc/systemd/system/vncserver@:1.service

Then open the configuration file/etc/systemd/system/vncserver@:1.service Replace the default user name

Find this line

Execstart=/sbin/runuser-l- 
 
  
   
   C "/usr/bin/vncserver%i" pidfile=/home/
  
   
    
   /.vnc/%h%i.pid
  
   
 
  

Here I log in directly with the root user, so I replaced

Execstart=/sbin/runuser-l root-c "/usr/bin/vncserver%i" pidfile=/root/.vnc/%h%i.pid

If it's another user, such as John, replace the following

Execstart=/sbin/runuser-l- 
 
  
   
   C "/usr/bin/vncserver%i" pidfile=/home/
  
   
    
   /.vnc/%h%i.pid
  
   
 
  

Step three, Reload Systemd

[Root@wic ~]# Systemctl Daemon-reload

Fourth step, set the password for VNC

[Root@wic ~]# vncpasswd

Fifth step, because CentOS 7 on my side is using iptable firewall, so

Vim/etc/sysconfig/iptables

In the right place add

-A input-m state--state new-m tcp-p TCP--dport 5900:5903-j ACCEPT

Restart Iptable

Service Iptables Restart

If you are using the CentOS 7 default firewall, you may need to

[Root@wic ~]# firewall-cmd--permanent--add-service vnc-server[root@wic ~]# systemctl Restart Firewalld.service

Sixth step, set the default startup and enable VNC

[Root@wic ~]# systemctl enable Vncserver@:1.service[root@wic ~]# systemctl start Vncserver@:1.service

So basically the CentOS end is set up, the Windows side to go to the next VNC Viewer software. Connect it and try it a little rough, but up there.
