Configuring a VNC Server

# yum -y install tigervnc-server
tigervnc is client and tigervnc-server is server.
Spcify settings for specific user:
# useradd lisa
# passwd lisa
# cd /usr/lib/systemd/system
# cp vncserver@.service vncserver@\:2.service
we need the backslash “\” because the “:” will be intepreted and is interpreted and “2” is for session. DO NOT use session “0” because cannot start the service.
Modify the content of vncserver@\:2.service
# vi vncserver@\:2.service
Replace with the user created above (lisa):
ExecStart=/sbin/runuser -l lisa -c “/usr/bin/vncserver %i”
Have to reload configuration files:
# systemctl daemon-reload
Before start the session, set the password for that user and this can be done by user:
# su – lisa
# vncpasswd
# exit
start the server:
# systemctl start vncserver@\:1
check the status:
# systemctl status vncserver@\:1
Setup firewall. Firewall prevent user come in and not go outside.
# firewall-cmd –permanent –ad-service vnc-server
# firewall-cmd –reload
