How to Install Oracle Java 6 update 45 on Ubuntu 12.04-64 Linux
This is a step-by-step installation instructions for Java on Ubuntu 64.
Open your console window and enter the following command:
$ java –version
If you get the following result, you already have Java 6 update 37 installed and can ignore the rest of the steps:
java -version
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode)
Step 1: Create the installation folder
$ sudo mkdir -p /usr/lib/jvm
The –p option ensures that all folders in the mkdir path 1s created.
Step 2: Download Oracle Java
Download jdk-6u45-linux-x64.bin and jre-6u45-linux-x64.bin from:
http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase6-419409.html#jre-6u45-oth-JPR
http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase6-419409.html#jdk-6u45-oth-JPR
Typicly:
$ cd ~/Downloads
Step 4: Move the downloaded files to the installation folder
$ sudo mv jdk-6u45-linux-x64.bin /usr/lib/jvm $ sudo mv jre-6u45-linux-x64.bin /usr/lib/jvm
Step 5: Change to the installation folder.
$ cd /usr/lib/jvm
Step 6: Make the downloaded binaries executable.
$ sudo chmod a+x jdk-6u45-linux-x64.bin $ sudo chmod a+x jre-6u45-linux-x64.bin
Step 7: Extract both compressed binary files.
$ sudo ./jdk-6u45-linux-x64.bin $ sudo ./jre-6u45-linux-x64.bin
Step 8: Check your extracted folder names.
$ ls -l
Response: jdk1.6.0_45 jre1.6.0_45
Step 9: Inform Ubuntu where your Java installation is located.
$ sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jre1.6.0_45/bin/java 1 $ sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.6.0_45/bin/javac 1
Step 10: Inform Ubuntu that this is your default Java installation.
$ sudo update-alternatives --set java /usr/lib/jvm/jre1.6.0_45/bin/java $ sudo update-alternatives --set javac /usr/lib/jvm/jdk1.6.0_45/bin/javac
Step 11: Update your system-wide PATH.
Edit your /etc/profile file using:
$ sudo gedit /etc/profile
Add the following entries to the bottom of the file:
JAVA_HOME=/usr/lib/jvm/jdk1.6.0_45
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin
export JAVA_HOME
export PATH
Save your changes and exit
Step 12:
Reload your system-wide PATH.
$ . /etc/profile
Step 13: Test your new installation.
$ java -version
Response:
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode)
$ javac -version
Response: javac 1.6.0_45
