Java version on Amazon Linux instance created from AMI version 2017.09.01 can be upgraded with following steps. These may work with recent version of Amazon Machine Images (AMIs).
Step 1: Copy the required version of Java to Amazon Linux
For this exercise we would be upgrading to Oracle Java 8 update 121 utilizing package jdk-8u121-linux-x64.rpm which can be downloaded from Oracle Downloads.
Once downloaded this can be copied to the Amazon Linux instance with Secure Copy Protocol (SCP).
Step 2: Remove currently installed Java version
List current Java version information with following command.
$ java -version java version "1.7.0_161" OpenJDK Runtime Environment (amzn-18.104.22.168.75.amzn1-x86_64 u161-b00) OpenJDK 64-Bit Server VM (build 24.161-b00, mixed mode)
List currently installed Java package.
$ sudo yum list installed '*java*'
Remove currently installed Java package.
$ sudo yum remove java-1.7.0-openjdk.x86_64 -y
Verify Java is uninstalled.
$ java -version -bash: /usr/bin/java: No such file or directory
Step 2: Install newer version of Java
Navigate to the location where newer version of Java was copied.
$ pwd /home/ec2-user $ ls jdk-8u121-linux-x64.rpm
Run following command to install Java.
$ sudo rpm -ivh jdk-8u121-linux-x64.rpm
Verify that Java is successfully installed.
$ java -version java version "1.8.0_121" Java(TM) SE Runtime Environment (build 1.8.0_121-b13) Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode) $ echo $JAVA_HOME /usr/lib/jvm/jre $ which java /usr/bin/java
