This article mainly introduces "how to configure Shell script to automatically install JDK in Linux system". In daily operation, I believe many people have doubts about how to configure Shell script to automatically install JDK in Linux system. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the question of "how to configure Shell script to automatically install JDK in Linux system". Next, please follow the editor to study!

A: the machine on which this script runs, Linux

B: the machine to be installed with JDK, Linux

First, on machine A where the script is running, make sure that ssh can log in without a password to machine B where you want to install jdk, and then you can run this script on A:

The code is as follows:

$. / IP of install-jdk.sh B

Or:

The code is as follows:

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

You can install JDK on machine B. The tar package used by jdk requires users to set their own DEFAULT_JDK_SRC=? It is guaranteed that it can be obtained by wget. Here is the full script:

The code is as follows:

#! / bin/bash

#

# @ file

# install-jdk.sh

#

# @ date

# 2013-12-19

#

# @ author

# cheungmine

#

# @ version

# 0.0.1pre

#

# @ usage:

#. / install-jdk.sh 192.168.122.206

#

#

. Common.sh

# *

# install_jdk

# install jdk on machine: / usr/local/lib

#

# Parameters:

# machine-root@ipaddr

# jdkUri-uri for fetching tarball

#

# Example:

#

# install_jdk root@192.168.122.206 ftp://vm-ftp/pub/tarball/jdk-7u67-linux-x64.tar.gz

#

# *

. Common.sh

# YOU MIGHT CHANGE BELOW LINE TO GET YOUR JDK TARBALL:

DEFAULT_JDK_SRC= "ftp://vm-ftp/pub/tarball/jdk-7u67-linux-x64.tar.gz"

# DO NOT CHANGE BELOW TWO LINES:

INSTALL_DIR= "/ usr/local/lib/java"
