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

1、配置源

选择的是aliyun源ubuntu 18.04(bionic)

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

2、安装离线所需要的所有包

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 

3、制作离线包

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

1、上传离线包

上传之前制作的离线包packages.tar.gz

2、 建立离线源

# 创建离线文件存放目录
mkdir -p /offline/packages

# 解压离线文件
tar -zxvf packages.tar.gz -C /offline/packages/

# 备份源文件
mv /etc/apt/sources.list /etc/apt/sources.list.bak

# 映射本地源
cat >>/etc/apt/sources.list <<EOF
deb [trusted=yes] file:///offline/packages/ ./
EOF

# 更新
apt-get update

3. 安装

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  # ip
netmast 255.255.255.0  
gateway 192.168.3.5    # 网关一般为 192.168.3.254  

vim /etc/resolv.conf

nameserver 114.114.114.114
