因内网搭建开发环境，需要做一个Ubuntu的本地镜像源。
一、镜像获取
1、先确认需要的镜像源的名称，可从https://help.ubuntu.com/ 查询
2、在Ubuntu下安装apt-mirror
sudo apt-get install apt-mirror
3、修改apt-mirror配置文件
sudo vi /etc/apt/mirror.list
我的配置文件如下：
############# config ################## # 以下注释的内容都是默认配置，如果需要自定义，取消注释修改即可 # set base_path /var/spool/apt-mirror
set base_path /opt/mirror/ubuntu # # set mirror_path $base_path/mirror # set skel_path $base_path/skel # set var_path $base_path/var # set cleanscript $var_path/clean.sh # 架构配置，i386/amd64，默认下载与本机相同的架构 set defaultarch amd64 # set defaultarch <running host architecture> # set postmirror_script $var_path/postmirror.sh # set run_postmirror 0 set nthreads 20 set _tilde 0 # ############# end config ############## # 下载18.04版本的镜像源bionic,如果需要其他版本，将bionic替换成对应版本的英文名称即可。名称从https://help.ubuntu.com/查询 deb http://mirrors.aliyun.com/ubuntu bionic main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu bionic-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu bionic-updates main restricted universe multiverse deb 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 main restricted universe multiverse #deb-src http://mirrors.aliyun.com/ubuntu bionic-security main restricted universe multiverse #deb-src http://mirrors.aliyun.com/ubuntu bionic-updates main restricted universe multiverse #deb-src http://mirrors.aliyun.com/ubuntu bionic-proposed main restricted universe multiverse #deb-src http://mirrors.aliyun.com/ubuntu bionic-backports main restricted universe multiverse clean http://mirrors.aliyun.com/ubuntu
4、创建镜像的本地目录
sudo mkdir -p /opt/mirrors/ubuntu
5、开始拉取镜像
sudo apt-miiror
二、本地镜像源的部署
1、安装web服务器（nginx）
sudo apt-get install nginx
2、配置web服务
sudo vi /etc/nginx/sites-available/default
我的配置如下：
server { listen 80 default_server; listen [::]:80 default_server; root /var/www/html; index index.html index.htm index.nginx-debian.html; server_name _; location / { try_files $uri $uri/ =404; autoindex on; autoindex_exact_size off; autoindex_localtime on; } }
3、镜像服务挂载
sudo ln -s /opt/mirrors/ubuntu/mirror/mirrors.aliyun.com/ubuntu /var/www/html/ubuntu
4、重新载入 nginx 服务
sudo service nginx reload
此时使用浏览器访问 http://127.0.0.1/ubuntu ，应该可以在 web 界面中浏览本地仓库中的软件包
三、局域网机器使用本地镜像源
1、修改更新源
sudo vi /etc/apt/sources.list
参考配置如下（127.0.0.1替换成前面部署的机器ip）：
deb http://127.0.0.1/ubuntu/ bionic main restricted universe multiverse deb http://127.0.0.1/ubuntu/ bionic-updates main restricted universe multiverse deb http://127.0.0.1/ubuntu/ bionic-backports main restricted universe multiverse deb http://127.0.0.1/ubuntu/ bionic-security main restricted universe multiverse deb http://127.0.0.1/ubuntu/ bionic-proposed main restricted universe multiverse
2、更新系统
sudo apt-get upgrade
3、更新软件索引
sudo apt-get update
4、软件安装
sudo apt-get install
