最后一行就是在下载jdk了，这里我们安装jdk1.6相关得全部包。

3.确认是否安装成功
[qyf@localhost ~]$ java -version

执行结果

[qyf@localhost ~]$ java -version

java version "1.6.0_30"

OpenJDK Runtime Environment (IcedTea6 1.13.3) (rhel-5.1.13.3.el5_10-i386)

OpenJDK Client VM (build 23.25-b01, mixed mode)

正确显示了jdk版本信息就说明安装成功了。

4.默认情况下jdk安装得路径

/usr/lib/jvm

由于我们得机器可能同时安装好几个版本得jdk，所以在/etc/alternatives目录下会有一个java链接到具体的java命令。而这个/etc/alternatives/java会被/usr/bin/java链接。从而java命令就被设置到了shell环境中。 与50位技术专家面对面20年技术见证，附赠技术全景图
