[Tutorial] How to install Java 8 on Linux CentOS 7 via SSH using PuTTY

[UPDATE: 07/16/2017 - Changed below description from Java 8 update 121 to Java 8 update 131, NOTE: THE VIDEO IS OUTDATED, ONLY THE DESCRIPTION IS CURRENT AS OF 07/16/2017. I will try to update as often as I can.)

In this tutorial, I show you how to install Java 8 on Linux CentOS 7 via SSH Terminal using PuTTY. Below will be the commands to use so that you can follow this tutorial.

STEP 01:

For 64Bit (Which is the version shown in the video)

# cd /opt/

# wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-linux-x64.tar.gz"

# tar xzf jdk-8u131-linux-x64.tar.gz


For 32Bit

# cd /opt/

# wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-linux-i586.tar.gz"

STEP 02: (Extracting the Archive)

# tar xzf jdk-8u131-linux-i586.tar.gz

**Note: If Above wget command does not work for you watch this example video to download java source archive using terminal.

STEP 03: (Installing with Alternatives)

# cd /opt/jdk1.8.0_131/

# alternatives --install /usr/bin/java java /opt/jdk1.8.0_131/bin/java 2

#alternatives --config java

In this example, there are 3 programs which provide 'java'.


Selection Command
-----------------------------------------------
+ 1 /opt/jdk1.8.0_131/bin/java
* 2 /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.131-3.b13.el7_2.x86_64/jre/bin/java
3 /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.111-2.6.7.2.el7_2.x86_64/jre/bin/java

Press [ENTER] to keep the current selection (The one marked with a +), or type the selection number you want (In this case: 4).

STEP 4: (Checking Java Version)

#java -version

If successfully installed, you should see something similar as listed below:

java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

That's all! So you should now have Java Installed!
