在Linux下安装Java JDK6.0

1) 先下载JDK1.6，如 JDK1.6.bin
2) 提权 chmod a+x *.bin
3) ./*.bin
4) rpm ivh *.rpm

5)配置环境变量
打开 /etc/profile ,即 vi /etc/profile ,在文本的最后添加如下内容，如：
export GRAILS_HOME=/grails path
export JAVA_HOME=/usr/java/jdk1.6.0_01
export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$GRAILS_HOME/lib
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$GRAILS_HOME/bin:$PATH

如果只对当前用户有用就要把配置文件放到.bashrc下了
echo "export JAVA_HOME=/usr/java/jdk1.6.0_01" >> /home/sonic/.bashrc
echo "export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib" >> /home/sonic/.bashrc
echo "export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH" >> /home/sonic/.bashrc
