Centos 7 VNC Remote Desktop Cannot Connect To Entity Session

On Centos 7, if you implement remote desktop using Tigervnc or XRDP, there is a problem: The local connection to the remote server is not the user session that the physical machine is currently logged in, but a new and isolated session. So what do we need to do to connect to the entity session, what should we do? X11vnc! It can help us achieve this.

Centos 7 VNC Remote Desktop Cannot Connect To Entity Session

Install

# yum -y install x11vnc

Set Password

# x11vnc -storepasswd

Enter VNC password:

Verify password:

Write password to /root/.vnc/passwd? [y]/n y

Password written to: /root/.vnc/passwd

Setting x11vnc Startup

  1. Create a new startVnc.sh file
    # touch /etc/rc.d/init.d/startVnc.sh
  2. Edit the startVnc.sh file
    # vim /etc/rc.d/init.d/startVnc.sh
  3. Add the following content, save and exit
    #!/bin/bash
    #chkconfig: 345 88 14
    nohup x11vnc --reopen --forever -rfbauth ~/.vnc/passwd &
  4. Create a new startVnc.service file
    # touch /usr/lib/systemd/system/startVnc.service
  5. Edit the startVnc.service file
    # vim /usr/lib/systemd/system/startVnc.service
  6. Add the following content, save and exit
    [Unit]
    Description=start vnc service
    Requires=graphical.target
    After=graphical.target
    [Service]
    Type=forking
    User=root
    Group=root
    Restart=always
    TimeoutSec=5
    IgnoreSIGPIPE=no
    KillMode=process
    GuessMainPID=no
    RemainAfterExit=no
    ExecStart=/etc/rc.d/init.d/startVnc.sh
    [Install]
    WantedBy=graphical.target
  7. Setting x11vnc startup
    # systemctl enable /usr/lib/systemd/system/startVnc.service
  8. Reboot
    # reboot
  9. Check if x11vnc is successfully started
    # netstat -anp | grep 5900

Configuration completed

Now, try connecting to this server with other vnc clients. How about? Is it successful?
