This article will explain in detail how to build VNC remote desktop service in CentOS 7.2. the editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

1. Graphical interface installation (MATE DESKTOP)

Under CentOS 7 system, this article uses the installation of MATE desktop environment for installation and configuration instructions:

Log in to the server and execute the following instructions to install the desktop environment:

# install MATE Desktopyum groups install "MATE Desktop" first

After the command is entered, a lot of text will be listed, then the y/d/n will be displayed, enter y, and press enter to download and install.

When the installation is complete, the following picture complete is displayed

# install MATE Desktop before installing X Window System. Yum groups install "X Window System"

After the command is entered, a lot of text will be listed, then the y/d/n will be displayed, enter y, and press enter to download and install.

Installation completed

Set to start the server through the desktop environment by default:

Systemctl set-default graphical.target

After the installation is completed, restart the server through reboot or other instructions, or restart the server in the ECS server console. After restart, the system will automatically enter the graphical interface.

Second, install vncserver

1. Assuming that your system does not have any software installed on vnc, install vnc first

Yum-y install tigervnc-server tigervnc

2. Centos7 needs to configure the file / lib/systemd/system/vncserver@.service, copy a file, and rename it to vncserver@:1.service

The copy code is as follows:

[root@localhost ~] # cp / lib/systemd/system/vncserver@.service/lib/systemd/system/vncserver@:1.service

3. Replace the contents in the file with your current user

[Unit] Description=Remote desktop service (VNC) After=syslog.target network.target [Service] Type=forkingUSER=root# Clean any existing files in/ tmp/.X11-unix environmentExecStartPre=/usr/bin/vncserver-kill% iExecStart=/usr/bin/vncserver% I-geometry 1280x720-depth 24PIDFile=/root/.vnc/%H%i.pidExecStop=/usr/bin/vncserver-kill% I [install] WantedBy=multi-user.target

4. Update systemctl

Systemctl daemon-reload

5. Set to start automatically

Systemctl enable vncserver@:1.service

6. Start the vnc service

Systemctl start vncserver@:1.service

7. Modify the configuration file (solve the problem of blue screen or gray screen when connecting to vncviewer)

Vim / .vnc/xstartup

#! / bin/sh # Uncomment the following two lines for normal desktop: # unset SESSION_MANAGER # exec / etc/X11/xinit/xinitrc [- x / etc/vnc/xstartup] & & exec / etc/vnc/xstartup [- r $HOME/.Xresources] & & xrdb $HOME/.Xresources xsetroot-solid grey vncconfig-iconic & x-terminal-emulator-geometry 80x24+10+10-ls-title "$VNCDESKTOP Desktop" & mate-session &

8. Restart the vnc service and enter the following two commands:

Vncserver-kill: 1 vncserver

After all configuration is completed (the settings for firewall release port 590X are not listed here), clients can use IP:5901 for remote desktop connection
