Rpm-qa | grep java//view JDK information

Yum-y Remove Java-1.6.0-openjdk-1.6.0.0-1.7.b09.el5//Uninstall

Download Sun's JDK http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html Download jdk-7u71-linux-i586.rpm

Create a Java directory under/usr in case the Java program is installed in this directory

Mkdir/usr/java

Cd/usr/java

RPM-IVH jdk-7u71-linux-i586.rpm Decompression, in the/usr/java directory will generate a new directory jdk1.7.0_71, the directory is stored in the extracted files.

For ease of Setup later, we created the directory jdk1.7.0_71 renamed JDK MV Jdk1.7.0_71 JDK

Finally, set the environment variable

Vi/etc/profile

Export JAVA_HOME=/USR/JAVA/JDK

Export path= $PATH: $JAVA _home/bin

Export classpath=.: $JAVA _home/jre/lib/rt.jar: $JAVA _home/lib/dt.jar: $JAVA _home/lib/tools.jar

Execute the configuration file to make it effective immediately source/etc/profile

Verify that the installation is successful

Java-version The following three lines appear to indicate success

Java Version "1.7.0_71"

Java (TM) SE Runtime Environment (build 1.7.0_71-b14)

Java HotSpot (TM) Client VMs (build 24.71-b01, Mixe dmode, sharing)
