z recently scanned ssh version is too low, yum update can be resolved, rose to 7.4
But to see the Internet that update to version 8.0 above it may solve the problem, then compile and install ssh 8
./configure --with-md5-passwords --with-pam --with-selinux --with-privsep-path=/var/lib/sshd/ --sysconfdir=/etc/ssh
make
make install
init 6
Then dumbfounded, vnc Rom. Ssh Fortunately, version did rise up, to 8.2
So the solution
Reinstall the desktop, reinstall vnc
# yum groups -y remove "GNOME Desktop" # yum groups -y install "GNOME Desktop"
yum install -y xrdp tigervnc-server
vncserver :1
vim /usr/lib/systemd/system/xrdp.service
-p 3389
stemctl daemon-reload
systemctl restart xrdp
# systemctrl restart xrdp
Or not,
