How Ubuntu connects to CentOS Remote Desktop

1. System software Setup
CentOS side:
See if the VNC software is installed
# rpm-q VNC vnc-server
Package VNC isn't installed
vnc-server-4.1.2-14.e15_3.1
The above information means that VNC is not installed, and Vnc-server is already installed.
Then, install the VC
# yum Install VNC
If the vnc-server is not installed, then
# yum Install Vnc-server
Ubuntu side:
Installing Vnc4server
$ sudo apt-get install Vnc4server
Set Password
$ vncpasswd
Password
Verify
$ vim ~/.vnc/xstartup
#!/bin/sh
# Uncomment the following-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" &
X-window-manager &
After the change is:
Note the last two lines, which are preceded by #
#x-terminal-emulator-geometry 80x24+10+10-ls-title "$VNCDESKTOP Desktop" &
#x-window-manager &
Then add
Gnome-session &
$ vnc4server
Warning:user-ms-7549:1 is taken because of/tmp/. X11-unix/x1
Remove This file if there is no X server user-ms-7549:1
Xauth:creating new Authority file/home/user/. Xauthority
New ' user-ms-7549:2 (user) ' Desktop is User-ms-7549:2
Creating default startup Script/home/user/.vnc/xstartup
Starting applications specified In/home/user/.vnc/xstartup
Log file Is/home/user/.vnc/user-ms-7549:2.log

2. Remote Desktop use
Using CentOS with Vncviewer (installed in the VNC package)
$ vncviewer
After Ubuntu Vnc4server is started, the default port is 5900
Then, the above new ' user-ms-7549:2 (user) ' Desktop is user-ms-7549:2 means +2,
So it's 5900+2=5902.
After OK, the password is the top
The password that is set in the $ vncpasswd.
If you're upside down, sign in to CentOS with Ubuntu Remote Desktop. Then install Xvnc4viewer in Ubuntu, set VNCPASSWD on CentOS, and the others will be reversed.
