Linux Auto-install JDK shell script

Linux Auto-install JDK shell script

A: This script runs the machine, Linux

B: The machine to install the JDK, Linux

First, on machine a where the script is running, you can log on to the machine B where the JDK is to be installed without SSH password, and then you can run this script on a:

$./install-jdk.sh B's IP

Or

$./install-jdk.sh "B's IP" "JDK uri"

You can install the JDK on machine B. The tar package used by the JDK requires the user to set the default_jdk_src= itself? , guarantee can be wget. Here are the full script contents:
