学校内有Ubuntu服务器使用需求，而且不能连接互联网，导致安装软件和更新都比较麻烦，需要建立一台本地更新源服务器。

目的：使Ubuntu服务器可以通过外网进行ssh登录

这里选用了中科大的镜像源： https://mirrors.ustc.edu.cn/repogen/

接下来更新源

Ubuntu 16.04 + xRDP + Xfce 实现Windows远程桌面连接

1. 安装xRDP及vncserver

2. 安装Xfce桌面环境

3. 设置xRDP

4. 设置配置文件

在. /etc/X11/Xsession 前一行插入

5. 重启 xrdp

6. 最后测试远程链接

Microsoft Remote Desktop

1. 安装apt-mirror

2. 配置apt-mirror

sudo vi /etc/apt/mirror.list

1. 创建postmirror.sh文件，否则会报类似can't open /opt/source/var/postmirror.sh错误

该文件用于执行同步软件源成功后所执行的 *** 作；

1. 安装apache2

2. 创建软链接

利用crontab设置定时任务

二、更新软件源

在此基础上，做了一些编辑和改动

Ubuntu下的包管理工具是dpkg和apt-get

在没有网络的情况下，要想安装软件包，并自动解决依赖问题，就需要将事先准备好的deb包(相当于centos下的rpm包)上传到服务器并制作local repo

示例：我需要装vim和cuda，但不知道依赖包有哪些。可以找一台联网的Ubuntu机器

包默认存放在/var/cache/apt/archives/目录下

假设我们存放包的目录是/home/pkgs

sudo apt-get install vim
