1. 根据系统32 /64 ，下载jdk-6u27-linux-x64.bin

$ sudo cp jdk-6u27-linux-i586.bin /usr/lib/jvm

$ cd /usr/lib/jvm

$ sudo ./jdk-6u27-linux-i586.bin

$ sudo mv jdk1.6.0_27/ java-1.6.0_27-sun/

$ sudo ln -s java-1.6.0_27-sun java-6-sun

$ sudo rm jdk-6u27-linux-i586.bin

配置文件修改：

$ sudo vi /etc/environment

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/lib/jvm/java-6-sun/bin"

CLASSPATH="/usr/lib/jvm/java-6-sun/lib"

JAVA_HOME="/usr/lib/jvm/java-6-sun"

更该使用的jdk路径：

$ sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/java-6-sun/bin/java 300

$ sudo update-alternatives --install /usr/bin/javac javac /usr/lib/java/java-6-sun/bin/javac 300

$ sudo update-alternatives --config java

------------------------------------------------------------

0 /usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 ×Ô¶¯Ä£Ê½

1 /usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 ÊÖ¶¯Ä£Ê½

* 2 /usr/lib/jvm/java-6-sun/bin/java 300 ÊÖ¶¯Ä£Ê½

确认是否安装成功：

$ java -version

java version "1.6.0_27"

Java(TM) SE Runtime Environment (build 1.6.0_27-b07)

Java HotSpot(TM) Server VM (build 20.2-b06, mixed mode)
