在CentOS中可以使用yum自动安装软件，在离线环境中却行不通。
- Linux localhost 3.10.0-327.el7.x86_64 #1 SMP Thu Nov 19 22:10:57 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
对于同一版本CentOS，我们可以事先下载离线依赖包，后面用命令手动安装。
- Java
自动安装命令：
yum install -y java
安装结果：

如果手动去一个个找依赖是很困难的，即便已经知道名字、版本，下面就依赖系统自带的命令完成该步骤
yum install --downloadonly --downloaddir=/home/java java

从download的过程来看，30个rpm需要按照，其中有3个为updates；
我们将update单独列出，这里需要在java目录新建update目录，然后将三个update类型rpm移动过去，最终形成文件树如下：

在同层目录，创建install.sh
[root@localhost java]# cat install.sh
#author : wangbaobao
#release : 2017-4-6
#company : YZ Co., LTD
rpm -ivh *.rpm
rpm -Uvh update/*.rpm
测试：
[root@localhost java]# chmod 750 install.sh
[root@localhost java]# sh install.sh

openjdk version "1.8.0_121"
OpenJDK Runtime Environment (build 1.8.0_121-b13)
OpenJDK 64-Bit Server VM (build 25.121-b13, mixed mode)
综上所述，可以通过预先下载依赖，快速完成1.8.0_121版本java的离线安装。
有个小问题，install.sh中rpm是先执行安装base还是updates?
===> 从目前来看，如果主文件为base则先安装updates，如果主文件为updates则先安装base。java主文件为update，所以shell中先执行base安装。
