Important Note on CentOS Java

Jenkins requires Java in order to run, however yum install jenkins does not enforce that java is already installed. Check to make sure that you already hava java installed by running java -version. To further make things difficult for CentOS users, the default CentOS version of Java is not compatible with Jenkins. Jenkins typically works best with a Sun implementation of Java, which is not included in CentOS for licensing reasons.

If you get output similar to the following, it means you're using the default (GCJ) version of Java, which will not work with Jenkins:

java -version
java version "1.5.0"
gij (GNU libgcj) version 4.4.6 20110731 (Red Hat 4.4.6-3)

To correct this, you may need to remove the GCJ version of Java and install a Sun-compatible version.

If you received the above output, uninstall the default java:

 yum remove java

Then after you've uninstalled Java (or if you didn't have Java installed at all to begin with). You need to install a Sun-compatible version of Java. The easiest approach is using OpenJDK, which is available through the EPEL repository (alternatively you may install an official RPM directly from Oracle). To install OpenJDK run the following:

 yum install java-1.6.0-openjdk

Depending on your version of CentOS, the package name for OpenJDK may differ. Use yum search openjdk to check for the name of the package. If OpenJDK is not found at all through yum, you probably need to install the EPEL yum repository. After installation, you should be able to get the following output for java -version:

java -version
java version "1.6.0_22"
OpenJDK Runtime Environment (IcedTea6 1.10.6) (rhel-1.43.1.10.6.el6_2-i386)
OpenJDK Client VM (build 20.0-b11, mixed mode)
OpenJDK Client VM (build 20.0-b11, mixed mode)
