每次安装linux操作系统都需要下载jdk，安装jdk，设置环境变量，很麻烦，这次写个脚本，一次搞定
view plain #!/bin/bash
chmod u+x jdk-6u29-linux-i586.bin installPath=/usr/java if [ ! -d /usr/java ];then mkdir /usr/java fi./jdk-6u29-linux-i586.bin -D /usr/java cp -R jdk1.6.0_29/ /usr/java/jdk1.6.0_29/
touch environment echo "PATH="$PATH：/usr/java/jdk1.6.0_29/bin"" >> environment echo "JAVA_HOME=/usr/java/jdk1.6.0_29/bin" >> environment echo "CLASSPATH=.：%JAVA_HOME%/lib/dt.jar：%JAVA_HOME%/lib/tools.jar" >> environment rm -rf /etc/environment cp environment /etc source /etc/environment update-alternatives ——install /usr/bin/java java /usr/java/jdk1.6.0_29/bin/java 300 update-alternatives ——install /usr/bin/javac javac /usr/java/jdk1.6.0_29/bin/javac 300 update-alternatives ——config java
