每次安裝linux操作系統都需要下載jdk，安裝jdk，設置環境變量，很麻煩，這次寫個腳本，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
