jdk快速安装脚本

-->

如果你有多台服务器需要安装JDK，不妨使用以下的脚本，在安装前定制一下脚本中的变量：JKD_ARCHIVE（jdk压缩包文件名） JDK_VERSION(解压后的目录名) INSTALL_DIR(目标目录)

 

#!/bin/sh

#auther:supersun

#email:supersun06@gmail.com

#homepage:http://supersun.biz

 

JKD_ARCHIVE="jdk1.5.tgz"

JDK_VERSION="jdk1.5.0_017"

INSTALL_DIR="/usr/local/"

 

HOSTLISTS="$*"

 

for HOST in $HOSTLISTS

do

 

ssh $HOST " if [ -d ${INSTALL_DIR}${JDK_VERSION} ]

then

 echo $JDK_VERSION has been installed

else

 echo  $JDK_VERSION hasnot been installed

 cd $INSTALL_DIR

 tar zxf -

 test -L java && rm java

 ln -s $JDK_VERSION java

 cat >/etc/profile.d/java.sh <<'EOF'

#!/bin/sh

JAVA_HOME=/usr/local/java

PATH=\$JAVA_HOME/bin:\$PATH

 

export JAVA_HOME PATH

EOF

 

fi" <$JKD_ARCHIVE

done

 

用法如下：

[supersun@supersun.biz java]$ sudo sh ins_jdk.sh host1

Password:

jdk1.5.0_017 hasnot been installed

[supersun@supersun.biz java java]$ s ssh mss1
