How to install latest JDK on EC2 node (Amazon Linux)

05 May 2018

By default there is OpenJDK-7:

[ec2-user@ip-1-2-3-4 ~]$ java -version
java version "1.7.0_171"
OpenJDK Runtime Environment (amzn-2.6.13.0.76.amzn1-x86_64 u171-b01)
OpenJDK 64-Bit Server VM (build 24.171-b01, mixed mode)

Download the java distrobutive (get a link from oracle site -> http://www.oracle.com/technetwork/java/javase/downloads/jdk10-downloads-4416644.html)
```
wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/10.0.1+10/fb4372174a714e6b8c52526dc134031e/jdk-10.0.1_linux-x64_bin.rpm
```
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.

Install the downladed distribution:

sudo yum install -y jdk-10.0.1_linux-x64_bin.rpm

Check the java version:

[ec2-user@ip-1-2-3-4 ~]$ java -version
java version "10.0.1" 2018-04-17
Java(TM) SE Runtime Environment 18.3 (build 10.0.1+10)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.1+10, mixed mode)

If you need to create $JAVA_HOME variable for all users ```bash
vi /etc/bashrc
export JAVA_HOME=/usr/java/jdk1.8.0_171-amd64 ```
