Install JDK in Linux

1. Installation

1) download JDK from the official website

Http://www.oracle.com/technetwork/java/javase/downloads/jdk6u38-downloads-1877406.html

I am here a 32-bit system, so download the jdk-6u38-linux-i586.bin binfile, after downloading, I put it under the/Softs directory

2) grant the executable permission to the Installation File

 
[Root @ localhost Softs]#Chmod + x jdk-6u38-linux-i586.bin
 

3) create a Java directory under the/usr directory

 
[Root @ localhost USR]#Mkdir Java
 

4) Go to the/usr/Java directory and execute

[Root @ localhost Java]#/Softs/jdk-6u38-linux-i586.bin
 

2. Configure Environment Variables

1) Open the/etc/profile file

 
[Root @ localhost USR]#VI/etc/profile
 

Add the following content at the end of the file:

 
Java_home =/usr/Java/jdk1.6. 0_38path=$ Java_home/Bin:$ PathClasspath= .:$ Java_home/Lib/Tools. jarexport java_homeexport pathexport classpath
 

Save and exit

2) execute the following statement to make the environment variable configuration take effect:

 
[Root @ localhost lib]#Source/etc/profile
 

3) Verify that the JDK installation and configuration are successful:

 
[Root @ localhost lib]#Java-versionJava version"1.6.0 _ 38"Java (TM) se Runtime Environment (build1.6.0 _ 38-B05) Java hotspot (TM) Client VM (build20.13-B02, mixed mode, sharing) [root@ Localhost lib]# 
 

3. Delete

If you want to delete the binary file, you can directly Delete the installation directory.

 
[Root @ localhost USR]#Rm-RF Java
