CentOS 7でGNOME VNCセッションを正しく設定する方法は?

CentOS 7のポート80でxvnc(正確に言えば)セッションを実行しようとしていますXvnc TigerVNC 1.8.0 - built Aug 9 2019 03:04:19

gnome-desktopを使用してgnome-desktopをインストールし、yum groupinstall "GNOME Desktop"TigerVNCをインストールしました。私のログ:

私のxは次のように始まります。

#!/bin/sh

# Uncomment the following two lines for normal desktop:
unset SESSION_MANAGER
# exec /etc/X11/xinit/xinitrc
exec gnome-session &

[ -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 &
