Installing VNC server on CentOS 7

VNC is a good remote tool, regardless of the Windows platform or Linux platform, due to the recent knowledge of CentOS, so it is ready to build a VNC server on CentOS 7 to enable me from the client machine through the VNC Viewer remote connection operation.

If you do not have a desktop environment installed (X Windows), you can install it using the following command, which takes a few minutes to install the packages.

[email protected] ~]# yum check-update[[email protected] ~]# yum groupinstall "X Windows System" [[email protected] ~]# Yu M 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

After rebooting, you can go to the CentOS 7 desktop environment.

Step 1 Install the VNC package by entering the following command

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

Step 2 Create a file in the/etc/systemd/system/directory [email protected]:1.service, and copy the instance configuration file/lib/systemd/system/[email protected] to which

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

Step 3 Open and edit the/etc/systemd/system/[email protected]:1.service file and replace the user entry with your own username

[Service] type=forking# Clean any existing files in/tmp/. X11-unix environmentexecstartpre=/bin/sh-c '/usr/bin/vncserver-kill%i >/dev/null 2>&1 | | : ' Execstart=/sbin/runuser-l root-c "/usr/bin/vncserver%i" pidfile=/root/.vnc/%h%i.pid

Note that as root, I am using the root account to log in, so <user> change to root

Step 4 Restart Systemd

[Email protected] system]# Systemctl daemon-reload

Step 5 Create a VNC password for the user

[Email protected] system]# VNCPASSWD

Here I create a password of 123456

Step 6 Enable and start the service

[Email protected] system]# systemctl enable [email protected]:1.serviceln-s '/etc/systemd/system/[email protected]:1. Service '/etc/systemd/system/multi-user.target.wants/[email protected]:1.service ' [[email protected] system]# Systemctl Start Vn[email Protected]:1.service

Step 7 allows the VNC service to pass through the firewall

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

Now I can remotely view the CentOS 7 graphical interface by using the VNC Viewer client running on WIN10

If you need to stop the VNC service, enter the following instructions.

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

Disable VNC service from System boot (permanent)

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

Stop the Firewall service

[Email protected] ~]# Systemctl stop Firewall.service

Had a nice day!
