Install jdk in Linux -- Jdk installation and Linux jdk Installation

One of the essential skills for Java software engineers: Install JDK in Linux

 

For programmers who choose to develop applications in Linux, installing Jdk in Linux is one of the essential technologies. Here, I used Ubuntu to demonstrate how to install JDK using command lines in Linux (the graphical interface is not taken into account !!!)

Step 1: Install a virtual machine

Step 2: Install Ubuntu

Step 3: Install JDK

Resource:

Ubuntu 10)
Linux ubuntu 2.6.35-22-generic # 33-Ubuntu SMP Sun Sep 19 20:34:50 UTC 2010 i686 GNU/Linux

Jdk1.7

Jdk-7u9-linux-i586.tar.gz

(1) jdk users generally like to regard it as a system application, so they generally like to create a new folder under/usr/-java is used to store the java installation path

Operation Command: sudo mkdir/usr/java

(2) mount the downloaded Jdk. (for resources to be mounted: Virtual Machine-> Settings-> options-> shared files always open-> Add resources to be mounted, finally, I mounted my jdk-7u9-linux-i586.tar.gz to the virtual machine/mnt/hgfs/resource that can be mounted.

(3) decompress the jdk-7u9-linux-i586.tar.gz and place it under the/usr/java directory and rename it JDK

Unzip command: sudo tar-zxvf-r jdk-7u9-linux-i586.tar.gz // usr/java

RENAME command: sudo mv jdk1.7.0 _ 09 jdk1.7

(4) Configure Environment Variables

Go to the configuration file vi/etc/profile.

Add a configuration file before umask 022

 

Export JAVA_HOME =/usr/java/jdk1.7

Export CLASSPATH =.: $ JAVA_HOME/jre/lib/rt. jar: $ JAVA_HOME/lib/dt. jar: $ JAVA_HOME/lib/tools. jar

Export PATH = $ PATH: $ JAVA_HOME/bin

 

Umask 022

 

(5) Finally, restart the client and enter java-version. The information displayed indicates that the client is successfully restarted.

 

Nagi @ ubuntu :~ $ Java-version
Java version "1.7.0 _ 09"
Java (TM) SE Runtime Environment (build 1.7.0 _ 09-b05)
Java HotSpot (TM) Client VM (build 23.5-b02, mixed mode)
Nagi @ ubuntu :~ $
