Sharing my simple working approach

Downloading the JDK

curl -LO https://corretto.aws/downloads/latest/amazon-corretto-11-x64-linux-jdk.tar.gz

note: check the ec2 instance's platform ie., x64, aarch64, x86, aarch32 etc.,because the wrong platform jdk installation will leads to /bin/java: /bin/java: cannot execute binary file

Extracting the JDK to /usr/java/

sudo tar -xvzf amazon-corretto-11-x64-linux-jdk.tar.gz -C /usr/java/

Run the below single line command to change the soft link for java files in (/usr/bin) directory

cd /usr/java/amazon-corretto-*-linux-x64/bin
for i in java javac jfr; do path=$(find `pwd`/$i -type f); echo $path; sudo alternatives --install /usr/bin/i $path 20000 ; sudo update-alternatives --config $i ; done

after the above command execution, there will be a command prompt that will ask you to choose the selection number which represents the file residing path and we should choose the number which refers to path /usr/java/amazon-corretto-*-linux-x64/bin/

The amazon-corretto jdk version may vary based on the timeline that you download. Currently the java version is 11.0.12.7.1

That's it execute java -version, you can see the java version as

openjdk version "11.0.12" 2021-07-20 LTS
OpenJDK Runtime Environment Corretto-11.0.12.7.1 (build 11.0.12+7-LTS)
OpenJDK 64-Bit Server VM Corretto-11.0.12.7.1 (build 11.0.12+7-LTS, mixed mode)

The error message Unable to find a match: java-1.8.0-openjdk means that the yum package manager cannot find the java-1.8.0-openjdk package in the repositories. This can happen if the package is not available in the repositories, or if the repositories are not configured correctly.

To fix this error, you can try the following:

1. Make sure that the repositories are configured correctly. You can do this by running the following command:

sudo yum repolist

This will list all of the repositories that are configured on your EC2 instance. Make sure that the repository that contains the java-1.8.0-openjdk package is listed.

2. If the repository is listed, try updating the repositories:

sudo yum update

This will update the package manager's knowledge of the repositories.

3. If the package is still not found, you can try installing it manually. You can download the java-1.8.0-openjdk RPM package from the Oracle website. Once you have downloaded the RPM package, you can install it using the following command:

sudo yum localinstall java-1.8.0-openjdk-*.rpm

Once the java-1.8.0-openjdk package is installed, you should be able to run the java -version command without any errors.

Here are some additional tips for installing Java on EC2:

• You can also use the Amazon Corretto distribution of OpenJDK, which is available in the Amazon Linux repositories. To install Corretto, run the following command:

sudo yum install java-11-amazon-corretto-11.0.5+10-1.amzn2.x86_64

Java 8 may not be available out-of-the-box on the AMI that you are looking for. However, you can always install it once the instance is created.

e.g. Check this post which explains how to install java 8 on Ubuntu OR check this post which explains how to install Java 8 on RHEL/Fedora/CentOS.
