Shell script Implementation installs Jdk_linux shell automatically in Linux system

A: This script runs the machine, Linux
B: The machine that installs the JDK, Linux

First, on machine A on which the script runs, determine that you can log on to machine B on the JDK by SSH without a password, and then you can run this script on a:

Copy Code code as follows:

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

Or

Copy Code code as follows:

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

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

Copy Code code as follows:
