Install Oracle JDK on CentOS

Install Oracle Java 8 JDK

Note: If you would like to install a different release of Oracle Java 8 JDK, go to the Oracle Java 8 JDK Downloads Page, accept the license agreement, and copy the download link of the appropriate Linux .rpm package. Substitute the copied download link in place of the highlighted part of the wget command.

Change to your home directory and download the Oracle Java 8 JDK RPM with these commands:

cd ~
wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u72-b15/jdk-8u72-linux-x64.rpm"

Then install the RPM with this yum command (if you downloaded a different release, substitute the filename here):
