Many applications needs VNC in order to be installed with a GUI, Oracle doesn't require GUI in order to be installed, but the GUI helps, BIG TIME !!! :)
Two libraries are needed to install VNC:
[root@lparaca install]# yum -y install vnc-server xterm Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: ftp.hosteurope.de * extras: ftp.hosteurope.de * updates: ftp.hosteurope.de Package tigervnc-server-1.8.0-2.el7_4.x86_64 already installed and latest version Package xterm-295-3.el7.x86_64 already installed and latest version Nothing to do [root@lparaca install]#
The start of the VNC session can be done as follows:
[root@lparaca install]# su - oracle Last login: Tue Jan 23 04:06:07 EST 2018 [oracle@lparaca ~]$ vncserver New 'lparaca:1 (oracle)' desktop is lparaca:1 Starting applications specified in /home/oracle/.vnc/xstartup Log file is /home/oracle/.vnc/lparaca:1.log [oracle@lparaca ~]$
This means, that VNC is open on terminal: 1 or port: 5901. From the VNC Client, you have to connect to: ServerIP:5901
