Linux自动安装JDK的shell脚本

Linux自动安装JDK的shell脚本A：本脚本运行的机器，LinuxB：待安装JDK的机器, Linux首先在脚本运行的机器A上确定可以ssh无密码登录到待安装jdk的机器B上，然后就可以在A上运行本脚本:$ ./install-jdk.sh B的IPor:$ ./install-jdk.sh "B的IP" "JDK的URI"就可以在机器B上安装JDK。jdk使用的tar包需要用户自己设定DEFAULT_JDK_SRC=？，保证可以wget得到即可。下面是全部脚本内容：#!/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 [email protected] 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"LOCAL_DIR="./.tmp"function install_jdk() { echo -e "<INFO> install jdk on machine: $1" local DEST_LOGIN=$1 local JDK_URI=$2 local TAR=$(basename $JDK_URI) echo -e "<INFO> jdk: '$JDK_URI'" wget -c $JDK_URI -P $LOCAL_DIR -O $LOCAL_DIR/$TAR $(is_empty_dir "$LOCAL_DIR/jdk_untar") local ret=$? case $ret in $DIR_NOT_EXISTED) mkdir -p $LOCAL_DIR/jdk_untar ;; $DIR_IS_EMPTY) ;; $DIR_NOT_EMPTY) rm -rf $LOCAL_DIR/jdk_untar/* ;; *) exit $ERR_FATAL_ERROR ;; esac # untar to jdk_untar tar -zxf $LOCAL_DIR/$TAR -C $LOCAL_DIR/jdk_untar $(is_empty_dir "$LOCAL_DIR/jdk_untar") local ret=$? if [ "$ret" -eq "$DIR_NOT_EMPTY" ]; then local jdk_home=`ls $LOCAL_DIR/jdk_untar 2>/dev/null` echo $jdk_home else exit $ERR_FATAL_ERROR fi echo -e "<INFO> create folder on: $DEST_LOGIN:$INSTALL_DIR" local ret=`ssh $DEST_LOGIN "mkdir $INSTALL_DIR"` echo -e "<INFO> copy $jdk_home/ to: $DEST_LOGIN:$INSTALL_DIR/" local ret=`scp -r $LOCAL_DIR/jdk_untar/$jdk_home $DEST_LOGIN:$INSTALL_DIR` # remove local tar rm -rf $LOCAL_DIR/jdk_untar local DEST_JAVA_HOME=$INSTALL_DIR/$jdk_home echo -e "<TODO> remove old settings for install_jdk in /etc/profile" echo -e "<INFO> set /etc/profile: JAVA_HOME=$DEST_JAVA_HOME" local ret=`ssh $DEST_LOGIN "echo '' >> /etc/profile"` local ret=`ssh $DEST_LOGIN "echo '#!{{[email protected]==>' >> /etc/profile"` local ret=`ssh $DEST_LOGIN "echo 'export JAVA_HOME=$DEST_JAVA_HOME' >> /etc/profile"` local ret=`ssh $DEST_LOGIN "echo 'export CLASSPATH=.:\$JAVA_HOME/lib/tools.jar:\$JAVA_HOME/lib/dt.jar' >> /etc/profile"` local ret=`ssh $DEST_LOGIN "echo 'export PATH=\$JAVA_HOME/bin:\$JAVA_HOME/jre/bin:\$PATH' >> /etc/profile"` local ret=`ssh $DEST_LOGIN "echo '#!<[email protected]}}'>> /etc/profile"` local ret=`ssh $DEST_LOGIN ". /etc/profile"`}function uninstall_jdk() { echo -e "<TODO> uninstall jdk from: $1"}#=======================================================================# ---- main() ----if [ -n $1 ]; then DEST_IP=$1 JDK_SRC=$DEFAULT_JDK_SRC if [ $# == 2 ]; then JDK_SRC=$2 fi echo -e "<INFO> install jdk on '$DEST_IP', jdk: '$JDK_SRC'" install_jdk "root@$DEST_IP" "$JDK_SRC"fi此外使用到了common.sh这个脚本：#!/bin/bash## @file# common.sh## @date# 2013-12-18## @author# cheungmine## @version# 0.0.1pre########################################################################## Error Codes:#ERR_NOERROR=0ERR_FATAL_ERROR=-100# current user is not a rootERR_NOT_ROOT=100# file is already existedERR_FILE_EXISTED=200#***********************************************************# chk_root# check if is a root user## Example:# chk_root#***********************************************************function chk_root() { if [ $UID -ne 0 ]; then echo -e "<chk_root> current user is not a root."
