1.解压到你想要放的目录，这个就随便了。比如你在你的/home/xxx/下建一个software目录，然后解压。
2.这里分为两个方法
(1)通过终端打开/etc/profile[执行命令: sudo gedit /etc/profile]
然后 在末尾行添加
#set java environment JAVA_HOME=/home/xiha/java/jdk/jdk1.8.0_31 CLASSPATH=.;$JAVA_HOME/lib.tools.jar PATH=$JAVA_HOME/bin
然后按保存,退出.
在终端上执行$source /etc/profile
接着终端上输入 $ java -version
如果看到类似这样的信息：
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) Client VM (build 25.5-b02, mixed mode)
那就证明jdk安装成功.
(2)用终端来配置环境变量
输入 $ sudo vi /etc/profile
在末尾行添加
#set java environment JAVA_HOME=/home/xiha/java/jdk/jdk1.8.0_31 CLASSPATH=.;$JAVA_HOME/lib.tools.jar PATH=$JAVA_HOME/bin
再换行输入:wq命令(意思是保存退出)
$ source /etc/profile 使更改的配置立即生效
$ java -version 查看JDK版本信息
如果看到类似这样的信息：
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) Client VM (build 25.5-b02, mixed mode)
那就证明jdk安装成功.
