在 http://www.oracle.com/technetwork/java/javase/downloads/jdk-6u26-download-400750.html官网下载jdk

注意：

Linux

Some Linux platforms, such as Red Hat and SuSE, are RPM-based, which provide an automated way to install software. Some Linux distributions, such as Ubuntu, are not RPM-based. For these Linux systems, you must manually install the Java platform by using a self-extracting binary file.

我是ubuntu，所以选择Linux x86 - Self Extracting Installer

然后参考http://www.oracle.com/technetwork/java/javase/install-linux-self-extracting-138783.html

cd <jdkdir>

sudo chmod a+x jdk-6u <version>-linux-i586.bin

sudo ./jdk-6u <version>-linux-i586.bin

配置环境变量：

sudo vi /etc/environment

输入

PATH＝"......:/usr/lib/jvm/java/jdk1.6.0_12/bin"
CLASSPATH=.:/usr/lib/jvm/java/jdk1.6.0_12/lib
JAVA_HOME=/usr/lib/jvm/java/jdk1.6.0_12

使生效？？

sudo source /home/ghoul/.bashrc
加入可选的java

update-alternatives --install /usr/bin/java java /usr/lib/jvm/java/jdk1.6.0_12/bin/java 300
update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/java/jdk1.6.0_12/bin/javac 300

改变java

update-alternatives --config java

查看

java -version
