Linux First Install oracle Start Error [How to Solve]

The following error occurs when installing Oracle for the first time:

[oracle@localhost db_1]$ ./runInstaller
ERROR: Unable to verify the graphical display setup. This application requires X display. Make sure that xdpyi                                               nfo exist under PATH variable.

No X11 DISPLAY variable was set, but this program performed an operation which requires it.

Solution:

[oracle@localhost db_1]$ export DISPLAY=:0
[oracle@localhost db_1]$ echo $DISPLAY
:0

After execution, the following problems occur:

[oracle@localhost db_1]$ ./runInstaller
ERROR: Unable to verify the graphical display setup. This application requires X display. Make sure that xdpyi                                               nfo exist under PATH variable.
