Ubuntu10.4 install jdk1.6
You know,If you want to develop java applications ,you'd better install jdk.Today,I will introduce you how to intall jdk1.6 on Ubuntu.Just follow me step by step.
First step
you should download jdk file from sun offcial website,
URL: http://www.oracle.com/technetwork/java/javase/downloads/jdk-6u29-download-513648.html (fixed)
fileName : jdk-6u29-linux-i586.bin
Tips: 1)Before you will download this file ,you should accept license agreement.
2)If your system is Ubuntu10.4 or other 32-bit system,you can't download the jdk-6u29-linux-x64.bin.When you use sudo sh jdk-6u29-linux-x64.bin,it will create a file that file's name is invalid encoding.
Second step
after file is donwloaded,we also can use command
ls to scan the file list.
Third step
OK,now we can install jdk,write command :
sudo sh jdk-6u29-linux-i586.bin A few miniutes later,you will be asked to press Enter key,Just do, You will see 'Done'.
Ok,Now jdk has been instaled by us，next step we will config environment variables for java
Fourth step
enter the command :
sudo gedit /etc/environment if you are similar with vim,you can use the command :
sudo vi /etc/environment Add the following lines in the end of file.
export JAVA_HOME=/home/alicus/Downloads/jdk1.6.0_29 export JRE_Home=>/home/alicus/Downloads/jdk1.6.0_29/jre export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JRE_HOME/lib
then enter command :
source ~/.bashrc it makes the changes effective
Fifth Step
You should know Ubuntu10.4 make the openjdk as its default jdk ,so we should make sun jdk to be
the default one,just use following commands :
sudo update-alternatives --install /usr/bin/java java /home/alicus/Downloads/jdk1.6.0_29/bin/java 300sudo update-alternatives --install /usr/bin/java java /home/alicus/Downloads/jdk1.6.0_29/bin/javac 300 use following command to scan the jdk priority:
sudo update-alternatives --config javato
Tips: sudo update-alternatives -- install is used to change the priority.
OK!Now you can enter
java -version to test if jdk is ok.
If you can see java version "1.6.0_29",Congratulations!!
