sudo chmod 777 jvm //修改jvm 的權限

cd /usr/lib/jvm //打開jvm

sudo chmod 777 jvm jdk-6u33-linux-x64.bin //修改jdk-6u33-linux-x64.bin權限

sudo sh jdk-6u33-linux-i586.bin //解壓安裝jdk-6u33-linux-i586.bin
sudo gedit /etc/environment 

/etc/environmentPATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/lib/jvm/jdk1.6.0_33/bin"

JAVA_HOME="/usr/lib/jdk1.6.0_33"CLASSPATH="/usr/lib/jdk1.6.0_33/lib" //配置環境變量

sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.6.0_33/bin/java 300 
sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.6.0_33/bin/javac 300 

sudo update-alternatives --config java 

ps:jdk-6u33-linux-i586.bin爲jdk版本,根據你下載的改變這個名字,jdk1.6.0_33/bin 是解壓安裝jdk-6u33-linux-i586.bin後生成的目錄,根據具體情況修改...
