Server installation desktop, local remote management through vnc, based on CentOS 7

This article is about installing a window environment based on CentOS 7, and then managing our VPS through vnc. It has been passed on vultr's CentOS 7 template. At the same time, unless otherwise specified, all operations are performed by the root user.

Reference from: linoxide.com/linux-how-to/install-configure-vnc-server-centos-7-0/

This tutorial is divided into 5 parts

1. Preparation

2. Install X-window

3. Install VNC

4. Configure VNC

5. Local connection and other considerations

1. Preparation

Please refer to the preparation of this article: http://www.138vps.com/jzjc/987.html

The port that needs to be opened in this article is 5901. If the firewall is firewall, you can use the following command to open it once and for all. If it is iptables, please refer to the article above.

firewall-cmd --permanent --add-service vnc-server

systemctl restart firewalld.service

Remember, there is nothing you need

yum update

2. Install X-Window

1. Run the following command to install X-Window first, if you confirm that X-Window is not installed. This will consume more time

yum groupinstall "X Window System"

yum install gnome-classic-session gnome-terminal nautilus-open-terminal control-center liberation-mono-fonts

unlink /etc/systemd/system/default.target

ln -sf /lib/systemd/system/graphical.target /etc/systemd/system/default.target

Okay, go to the management background and restart your vps, or enter the following command to restart

sync

reboot

3. Install VNC

Run the following command

yum install tigervnc-server

4. Configure VNC

Run the following command

cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:1.service

Then use your WinSCP to edit the file [/etc/systemd/system/vncserver@:1.service]. Find the similar lines at the bottom and replace them with

[Unit]

Description=Remote desktop service (VNC)

After=syslog.target network.target

[Service]

Type=simple

# Clean any existing files in /tmp/.X11-unix environment

ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill :1 > /dev/null 2>&1 || :'

ExecStart=/sbin/runuser -l root -c "/usr/bin/vncserver :1 -geometry 1280x720 -depth 24"

PIDFile=/root/.vnc/%H%i.pid

ExecStop=/bin/sh -c '/usr/bin/vncserver -kill :1 > /dev/null 2>&1 || :'

[Install]

WantedBy=multi-user.target

Okay, let’s restart systemd.

systemctl daemon-reload

Set the password for vnc, run the following command, and then enter the password (I missed this step at the beginning and spent two hours troubleshooting)

vncpasswd

5. Local connection and other considerations

Here are some commands you should remember:

#Start VNC on boot

systemctl enable vncserver@:1.service

#Start service

systemctl start vncserver@:1.service

#Close VNC service

systemctl stop vncserver@:1.service

Disable VNC startup at boot

systemctl disable vncserver@:1.service

Here, we refer to the above command to start VNC.

Then you can open your beloved vncviewer and access your vps through [IP:5901]. At this time, the VPS is still very simple and we need to install some other commonly used software, such as firefox:

yum -y install firefox

After installation, you can see that there is already a browser, but the browser at this time does not support Chinese because our system does not have Chinese installed. How to install Chinese on Baidu.
