linux-ubuntu-myeclipse8.5 Installation

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

3. 
   

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:

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

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

10. Select Path Priority state

12. ------------------------------------------------------------

14. * 0/usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 Auto mode

16. 1/usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 Manual Mode

18. 2/usr/lib/jvm/java-6-sun/jre/bin/java 63 Manual Mode

20. 3/usr/lib/jvm/java-7-sun/bin/java 300 Manual Mode

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

28. 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)
