AWS - How to install java11 on an EC2 Linux machine?

Question

I tried this

Downloading Java JDK on Linux via wget is shown license page instead

but I keep getting a 404 error.

This command "sudo amazon-linux-extras install java-openjdk11" just states that amazon-linux-extras doesnt exist.

Answer 1

Another option might be running the following commands:

In order to install java 11:

sudo amazon-linux-extras install java-openjdk11

For java 8 you can try:

sudo yum install java-1.8.0-openjdk

Finally, if you want to switch between java versions run:

sudo alternatives --config java

Answer 2

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 $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)

Answer 3

Use one of the OpenJDK distributions:
