ubuntu 离线安装 内网安装 无外网安装 离线源

做政府或则企业的项目，通常是本地部署或则私有云，为了防止无外网，或防止现场安装时难以寻找到依赖包的情况发生，需要在开发阶段就准备好所有线上需要的工具或服务，所以需要制作离线包。Ubuntu离线安装软件原理是，在正常有网的开发服务器上安装所有依赖内容，并制作为本地源包，在目标服务器上解压后映射本地源，进行无外网安装。

一、离线包制作

mv /etc/apt/sources.list /etc/apt/sources.list.bak cat >>/etc/apt/sources.list <<EOF deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse EOF apt-get update apt-get upgrade 

apt-get install openssh-server apt-get install -y sysstat apt-get install -y gawk apt-get install -y bc apt-get install -y unzip apt-get install -y wget apt-get install -y iptables-persistent apt-get install -y psmisc apt-get install docker-compose apt-get install -y postgresql-11 apt-get install -y postgresql-11-postgis-2.5 

cd /var/cache/apt/archives/ dpkg-scanpackages . | gzip -9c > Packages.gz tar -zcf packages.tar.gz ./* 

packages.tar.gz就是制作好的离线包

二、内网安装

上传之前制作的离线包packages.tar.gz

 mkdir -p /offline/packages  tar -zxvf packages.tar.gz -C /offline/packages/  mv /etc/apt/sources.list /etc/apt/sources.list.bak  cat >>/etc/apt/sources.list <<EOF deb [trusted=yes] file:///offline/packages/ ./ EOF  apt-get update 

apt-get install -y wget apt-get install -y gawk apt-get install -y docker-ce apt-get install -y docker-compose apt-get install -y postgresql-11 apt-get install -y postgresql-11-postgis-2.5 

附 网络配置

vim /etc/network/interfaces
eth0是网卡名称，ip addr查看

auto eth0 iface eth0 inet static address 192.168.3.113  netmast 255.255.255.0 gateway 192.168.3.5  

vim /etc/resolv.conf

nameserver 114.114.114.114
