Installation of the 32-bit JDK on RPM-based Linux Platforms

This procedure installs the Java Development Kit (JDK) for 32-bit RPM-based Linux platforms, such as Red Hat and SuSE, using an RPM binary file (.rpm) in the system location. You must be root to perform this installation.
These instructions use the following file:

    jdk-7u-linux-i586.rpm

1. Download the file. Before the file can be downloaded, you must accept the license agreement.
2. Become root by running su and entering the super-user password.
3. Uninstall any earlier installations of the JDK packages.

    # rpm -e 

4. Install the package.

    # rpm -ivh jdk-7u-linux-i586.rpm

To upgrade a package:

    # rpm -Uvh jdk-7u-linux-i586.rpm

5. Delete the .rpm file if you want to save disk space.
6. Exit the root shell. No need to reboot.
