我们有时会在不能连接外网的机器上安装软件，这种情况我们只能提前下载好软件的所有依赖包，才能顺畅的安装好软件。
一般会有两种方式，一种是自建一个软件包仓库，一种是下载所有依赖包。
我编写了一个脚本来帮助大家 一键下载软件及依赖的离线包，接下来我们就来介绍下这个怎么用吧。
使用
脚本帮助
[root@node130 ~]# wget https://raw.githubusercontent.com/lework/script/master/shell/get_packages.sh
[root@node130 ~]# bash get_packages.sh
Download Packages With Dependencies Locally.
Usage:
get_packages.sh system package [package repo]
Support system:
centos6 centos7 centos8 debian8 debian9 debian10
Example:
get_packages.sh centos7 ansible
get_packages.sh centos7 "python36 python36-devel"
get_packages.sh centos7 ceph /root/ceph.repo
Usage: 使用的格式，package repo 需要指定绝对路径
Support system: 支持的系统
Example: 示例
centos7-ansible
下载 centos7 系统上 ansible 的相关依赖包
因为要在 centos 7 系列系统上安装 ansible
[root@node130 ~]# bash get_packages.sh centos7 ansible

这个脚本会先下载 docker 镜像 centos:7, 然后更新仓库缓存，接着下载软件包及依赖。最后退出容器打印软件包列表，软件存储在脚本运行目录的package_centos7_ansible目录中，拿着这些包就可以去无网的机器上安装了 (yum localinstall *.rpm)。
centos7-python36
下载 centos7 系统上 python36 的相关依赖包

使用 dpkg -i *.deb 就能安装吧。
