Access CentOS from the other machine (via VNC)
On target machine
yum groupinstall "GNOME Desktop"
Set default target to GUI:
systemctl set-default graphical.target
yum install tigervnc-server xorg-x11-fonts-Type1
Choose a VNC display to use for accessing this particular computer (here we'll use display 5 which equals to the port 5905)
cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:5.service
Add user (if you need one) whose Desktop will be accessed:
adduser admin
passwd admin
Access file:
vi /etc/systemd/system/vncserver@:5.service
Then:
- Go to [Service]
- ExecStart - here - change <USER> with admin
- PIDFile - here - change <USER> with admin
firewall-cmd --permanent --zone=public --add-port=5905/tcp
firewall-cmd --reload
su - admin
Execute vncserver command to assign VNC password for needed user (admin in our case)
systemctl daemon-reload
systemctl start vncserver@:5.service
systemctl enable vncserver@:5.service
systemctl status vncserver@:5.service
Check that vncserver is listening to the ports other that localhost:
lsof -i -P | grep -i "listen" | grep Xvnc
Check that vncserver is listening to the ports other that localhost:
lsof -i -P | grep -i "listen" | grep Xvnc
If some kind of problem appears do below:
Remove not needed VNC display sessions (if any):
rm -f /tmp/.X11-unix/*
rm -f /tmp/.X*-lock
systemctl restart vncserver@:5.service
ps aux | grep vnc
On client machine
yum install tigervnc
Open TigerVNC Viewer (Applications > Internet) or vncviewer (from bash)
Specify serverNameOrIp:5095
Specify VNC password
then login using needed login and password (admin in our case)
Specify VNC password
then login using needed login and password (admin in our case)
Use F8 to make full-screen and to change other settings.
