Installing Java 1.6 (OpenJDK) in CentOS 5.x from EPEL

I am posting this mini guide for those needing a quick guide in installing OpenJDK in CentOS 5.x.

The how-to information in CentOS community wiki sites explains how to build the rpms yourself from various JDK providers (IBM, Sun/Oracle, etc); but this is not what I wanted. What I wanted is to leverage existing yum repositories for CentOS, and this is where EPEL (Extra Packages for Enterprise Linux) comes to mind.


  • CentOS 5.x – this guide has been tested against 5.2
  • root access
  • yum

Add EPEL to your yum repositories:

cd /tmp && wget -c
rpm -Uvh epel-release-5-4.noarch.rpm

Install OpenJDK

yum install java-1.6.0-openjdk java-1.6.0-openjdk-devel

Check java and javac versions

java -version
javac -version

You’re done!
