I would like to install java on an Amazon linux2 EC2 instance.
After launching and executing sudo yum update, check if java is included
[ec2-user@ip-10-0-0-127 ~]$ java -version
-bash: java: command not found
I don't think it's in
Find java
[ec2-user@ip-10-0-0-127 ~]$ sudo yum search java
Loaded plugins: extras_suggestions, langpacks, priorities, update-motd
