bashrc file contained therein and add the following line at the end of the file (modifying the path to match the location of the JDK on your system): export PATH=/home/demo/java/jdk1.7.0_45/bin:$PATH For example, change directory to your home directory, edit the. bashrc file in your home directory (specifics may differ depending on the particular Linux distribution in use). This can typically be achieved by adding a command to the. For example, assuming that the JDK ultimately installed into /home/demo/java/jdk1.7.0_45 the following would need to be added to your $PATH environment variable: /home/demo/java/jdk1.7.0_45/bin Add the path to the bin directory of the JDK installation to your $PATH variable.

Execute the following command (where is replaced by the name of the downloaded JDK file): tar xvfz. Download the appropriate tar.gz package from the Oracle web site into the directory.ģ.

Create the directory into which the JDK is to be installed (for the purposes of this example we will assume /home/demo/java).Ģ. To install using the compressed tar package (tar.gz) perform the following steps:ġ.

Assuming, for example, that the downloaded JDK file was named jdk-7u45-linux-圆4.rpm, the commands to perform the installation would read as follows: su rpm JDK file from the Oracle web site and perform the installation using the rpm command in a terminal window. On Red Hat based Linux systems, download the. Packages are provided by Oracle in RPM format (for installation on Red Hat Linux based systems such as Red Hat Enterprise Linux, Fedora and CentOS) and as a tar archive for other Linux distributions such as Ubuntu. Firstly, if the chosen development system is running the 64-bit version of Ubuntu then it is essential that the 32-bit library support package be installed: sudo apt-get install ia32-libsĪs with Windows based JDK installation, it is possible to install the JDK on Linux by downloading the appropriate package from the Oracle web site, the URL for which is as follows:
