Install Java 8
Java is a high-level, class-based, object-oriented programming language . This article will help you to know how to install JAVA 8 on CentOS/Fedora/RHEL.

I hope our Java 7 installation tutorial was helpful to you. So after Java 7, here is our easy tutorial on installing Java 8 in your CentOS/Fedora/RHEL system.


1) Download the Source Package

You can download the latest Java 8 packages from here ( At the time of writing, the newest version is JDK 8u25, so that we will be installing that version ).

For 32 Bit :

cd /opt
wget --no-cookies --no-check-certificate --header "Cookie:; oraclelicense=accept-securebackup-cookie" ""


For 64 Bit :

cd /opt 
wget --no-cookies --no-check-certificate --header "Cookie:; oraclelicense=accept-securebackup-cookie" ""


2) Extract the archive file

For 32 Bit :

tar -xvf jdk-8u25-linux-i586.tar.gz


For 64 Bit :

tar -xvf jdk-8u25-linux-x64.tar.gz


3 ) Install and configure Java, Javac, and Jar

We will be using the “alternative” command to install and configure java, javac, and jar

cd /opt/jdk1.8.0_25/
alternatives --install /usr/bin/java java /opt/jdk1.8.0_25/bin/java 2
alternatives --config java


( alternatives –config java command will let you choose the desired Java version if you have multiple versions installed in your system. Make sure you choose the version we are installing )

alternatives --install /usr/bin/javac javac /opt/jdk1.8.0_25/bin/javac 2
alternatives --install /usr/bin/jar jar /opt/jdk1.8.0_25/bin/jar 2
alternatives --set javac /opt/jdk1.8.0_25/bin/javac
alternatives --set jar /opt/jdk1.8.0_25/bin/jar


4) Setup Environment Variables

If you install Java-based applications such as Tomcat, you may have to configure the following environment variables.

export JAVA_HOME=/opt/jdk1.8.0_25
export JRE_HOME=/opt/jdk1.8.0_25/jre
export PATH=$PATH:/opt/jdk1.8.0_25/bin:/opt/jdk1.8.0_25/jre/bin


5) Check and Verify

java -version


So that’s how you install JAVA 8 on CentOS/Fedora/RHEL.
