First step: Download jdk-7u79-linux-x64.tar.gz
    1. Wget-c http://download.oracle.com/otn-pub/java/jdk/7/jdk-7-linux-i586.tar.gz

(Note: If the download is not down, it is recommended to use Thunderbolt download, and then copied to the Linux system.) )

Step Two: Unzip the installation
    1. sudo tar zxvf jdk-7u79-linux-x64.tar.gz

    2. Cd/usr/lib/jvm


Step Three: Modify environment variables
    1. Vim ~/.BASHRC

Add to:

    1. Export java_home=/usr/lib/jvm/jdk1.7.0_79

    2. Export JRE_HOME=${JAVA_HOME}/JRE

    3. Export Classpath=.:${java_home}/lib:${jre_home}/lib

    4. Export Path=${java_home}/bin: $PATH

Save the exit and enter the following command to take effect immediately.

    1. SOURCE ~/.BASHRC

Fourth Step: Configure the default JDK version

Since there may be a default JDK in Ubuntu, such as OPENJDK, we will do the following to set up our installed JDK as the default JDK version.
Execute code:

    1. sudo update-alternatives--install/usr/bin/java Java/usr/lib/jvm/jdk1.7.0_79/bin/java 300

    2. sudo update-alternatives--install/usr/bin/javac Javac/usr/lib/jvm/jdk1.7.0_79/bin/javac 300

    3. sudo update-alternatives--install/usr/bin/jar Jar/usr/lib/jvm/jdk1.7.0_79/bin/jar 300

    4. sudo update-alternatives--install/usr/bin/javah javah/usr/lib/jvm/jdk1.7.0_79/bin/javah 300

    5. sudo update-alternatives--install/usr/bin/javap JAVAP/USR/LIB/JVM/JDK1.7.0_79/BIN/JAVAP 300


Execute code:

    1. sudo update-alternatives--config java


The various JDK versions are listed as follows:

  1. [Email protected]:~$ sudo update-alternatives--config java

  2. There are 3 candidates that can be used to replace Java (providing/usr/bin/java).

  3. Select Path Priority state

  4. ------------------------------------------------------------

  5. * 0/usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 Auto mode

  6. 1/usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 Manual Mode

  7. 2/usr/lib/jvm/java-6-sun/jre/bin/java 63 Manual Mode

  8. 3/usr/lib/jvm/java-7-sun/bin/java 300 Manual Mode

  9. To maintain the current value [*] press ENTER, or type the number of your choice: 3

  10. Update-alternatives: Use/usr/lib/jvm/java-7-sun/bin/java to provide/usr/bin/java (Java) in manual mode.

Fifth Step: Test

[Plain] view plaincopy

    1. [email protected]:/usr/lib/jvm/jdk1.7.0_79$ java-version

    2. Java Version "1.7.0_79"

    3. Java (TM) SE Runtime Environment (build 1.7.0_79-b15)

    4. Java HotSpot (TM) 64-bit Server VM (build 24.79-b02, Mixed mode)
