Centos 7 Installation VNC step

Let's just say what VNC is. (Virtual Network Computing) 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.

[Email protected] ~]# 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

[email protected] ~]# yum check-update[[email protected] ~]# yum groupinstall "X Window System" [[email protected] ~]# Yum Install gnome-classic-session gnome-terminal nautilus-open-terminal control-center liberation-mono-fonts[[email Protected] ~]# Unlink/etc/systemd/system/default.target[[email protected] ~]# ln-sf/lib/systemd/system/ Graphical.target/etc/systemd/system/default.target[[email protected] ~]# reboot

The first step is to install the VNC packages:

[email protected] ~]# Yum install tigervnc-server-y

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

[Email protected] ~]# cp/lib/systemd/system/[email protected]/etc/systemd/system/[email Protected]:1.service

Then open the configuration file/etc/systemd/system/[email Protected]:1.service Replace the default user name

Find this line

Execstart=/sbin/runuser-l <USER>-C "/usr/bin/vncserver%i" pidfile=/home/<user>/.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 linoxide, replace the following

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

Step three, Reload Systemd

[Email protected] ~]# Systemctl daemon-reload

Fourth step, set the password for VNC

[Email protected] ~]# 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

[Email protected] ~]# firewall-cmd--permanent--add-service vnc-server[[email protected] ~]# systemctl Restart firewall D.service

Sixth step, set the default startup and enable VNC

[Email protected] ~]# systemctl enable [email protected]:1.service[[email protected] ~]# systemctl start [email protected ]: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.
