搭建ubuntu系统的本地仓库

1. 应用场景

• 当我们需要在多台电脑安装同一个软件，并且这个软件很大，下载需要很长时间；
• 需要安装软件的ubuntu系统不能上网；

2. 制作流程

• 操作系统版本为：18.04.1-Ubuntu
• ubuntu源地址配置文件存储路径为：/etc/apt/sources.list
• 安装包默认存储路径为：/var/cache/apt/archives

在可以上网的ubuntu系统中将需要离线安装的包下载下来，由于默认ubuntu系统的源下载安装包较慢，将源更新为阿里云的源

sudo vi /etc/apt/sources.list 

内容如下：

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted deb http://mirrors.aliyun.com/ubuntu/ bionic universe deb http://mirrors.aliyun.com/ubuntu/ bionic-updates universe deb http://mirrors.aliyun.com/ubuntu/ bionic multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-updates multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted deb http://mirrors.aliyun.com/ubuntu/ bionic-security universe deb http://mirrors.aliyun.com/ubuntu/ bionic-security multiverse 

通过如下指令下载XXXX软件所需要的deb包，以openssh-server为例：

sudo apt-get -y install openssh-server 

执行完上述指令后，openssh-server安装完毕并且安装包已下载至默认存储目录。

3. 离线安装

将offlinePackage.tar.gz复制到根目录下，解压

sudo tar zxvf offlinePackage.tar.gz -C / 

添加之前可以先将原来的源备份

sudo cp /etc/apt/sources.list /etc/apt/sources.list.back 

将安装包所在和源路径添加到系统源文件中，内容如下：

deb [trusted=yes] file:/// offlinePackage/ 

注意：

若搭建局域网内部源，则配置文件内容应修改如下：

deb [trusted=yes] http://192.168.91.128 / 

sudo apt-get update 

输出如下：

sudo apt-get -y install openssh-server --allow-unauthenticated 

注意：一定要带上–allow-unauthenticated参数！
