This article will help you to Install JAVA 8 (JDK 8u25) or update on your system. Read instruction carefully for downloading java from Linux command line. To Install Java 8 in Ubuntu and LinuxMint read This Article.

Step 1: Download JAVA Archive

Download latest Java SE Development Kit 8 release from its official download page or use following commands to download from shell.

For 64Bit

# cd /opt/
# 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/8u25-b17/jdk-8u25-linux-x64.tar.gz"

# tar xzf jdk-8u25-linux-x64.tar.gz

For 32Bit

# cd /opt/
# 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/8u25-b17/jdk-8u25-linux-i586.tar.gz"

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

Note: If Above wget command doesn’t not worked for you watch this screencast to download JDK from terminal.

Step 2: Install JAVA using Alternatives

After extracting archive file use alternatives command to install it. alternatives command is available in chkconfig package.

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


There are 3 programs which provide 'java'.

  Selection    Command
-----------------------------------------------
*  1           /opt/jdk1.8.0/bin/java
 + 2           /opt/jdk1.7.0_55/bin/java
   3           /opt/jdk1.8.0_25/bin/java

Enter to keep the current selection[+], or type selection number: 3

At this point JAVA 8 has been successfully installed on your system. We also recommend to setup javac and jar commands path using alternatives

# alternatives --install /usr/bin/jar jar /opt/jdk1.8.0_25/bin/jar 2
# alternatives --install /usr/bin/javac javac /opt/jdk1.8.0_25/bin/javac 2
# alternatives --set jar /opt/jdk1.8.0_25/bin/jar
# alternatives --set javac /opt/jdk1.8.0_25/bin/javac 
Step 3: Check Version of JAVA .

Check the installed version of java using following command.

# java -version 

java version "1.8.0_25"
Java(TM) SE Runtime Environment (build 1.8.0_25-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)

Step 4: Setup Environment Variables

Most of java based application’s uses environment variables to work. Set the java environment variables using following commands

  • Setup JAVA_HOME Variable
  • # export JAVA_HOME=/opt/jdk1.8.0_25
    
  • Setup JRE_HOME Variable
  • # export JRE_HOME=/opt/jdk1.8.0_25/jre
    
  • Setup PATH Variable
  • # export PATH=$PATH:/opt/jdk1.8.0_25/bin:/opt/jdk1.8.0_25/jre/bin

  1. Thank you so much.

    Maybe useful for other readers:
    – On a vanilla fedora (or at least on my system), ‘alternatives’ doesn’t seem to be in the path, so the full path has to be specified:
    sudo /usr/sbin/alternatives –install /usr/bin/java java /opt/jdk1.8.0_05/bin/java 2
    sudo /usr/sbin/alternatives –config java

    – In case folks are not familar, the export commands can go into ~/.bash_profile , but careful not to overwrite your existing “PATH”, instead append to it. This is an example of my ~/.bash_profile
    # .bash_profile

    # Get the aliases and functions
    if [ -f ~/.bashrc ]; then
    . ~/.bashrc
    fi

    # User specific environment and startup programs

    PATH=$PATH:$HOME/.local/bin:$HOME/bin:$HOME/Dropbox/Apps/Bash_path_linux/:/opt/jdk1.8.0_05/bin:/opt/jdk1.8.0_05/jre/bin

    export JAVA_HOME=/opt/jdk1.8.0_05
    export JRE_HOME=/opt/jdk1.8.0_05/jre
    export PATH

    Hope it helps.

    • Hello sir, Im trying to install the latest java on my VPS to run a simple .jar file and the 1st step “tar xzf jdk-8u25-linux-x64.tar.gz” returns

      # tar xzf jdk-8u25-linux-x64.tar.gz
      tar (child): jdk-8u25-linux-x64.tar.gz: Cannot open: No such file or directory
      tar (child): Error is not recoverable: exiting now
      tar: Child returned status 2
      tar: Error is not recoverable: exiting now

      Running “uname -a” returns , which I presume is 64bit, Im using Centos 6. #1 SMP Mon Aug 11 18:47:39 MSK 2014 x86_64 x86_64 x86_64 GNU/Linux. I tried installing via both SSH and terminal of the VPS itself. Both returned the same result, what have I done wrong? Any help would be greatly appreciated.
