Hotfix To Install Latest Oracle JDK On Linux EC2 Instance (CentOS)

In this blog we will explore the procedure to install latest java 8 version ie JDK 8u121 (released on 17th January, 2017) on the EC2 Linux instance which comes with centOS as its default operating system. Following steps must be followed sequentially :

Step 1 -> Ssh to your instance

Refer Step 4 of this blog to ssh to your instance.

Step 2 -> Check the Java version

java -version


As can be seen in the image above, java 7 is installed on the EC2 instance by default. We will now be updating to java 8.

Step 3 -> Download RPM package of Oracle JDK (8u121)

 wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie"


NOTE -> It is important to manually instruct wget to send the cookie and here this is done using

–header “Cookie: oraclelicense=accept-securebackup-cookie”

where oraclelicense is the name of the cookie and accept-securebackup-cookie is its value.

Step 4 -> Install JDK 8

sudo yum install -y jdk-8u141-linux-x64.rpm

Step 5 -> Verify oracle JDK version

java -version

The java version is now updated. You may now delete jdk-8u121-linux-x64.rpm file.

Hope the blog helps you. Questions are welcomed.
