一键配置脚本（用户添加配置、源修改、ss&BBR安装）

最近在各个服务器提供商中尝试适合的服务器，然而给多个服务器初始配置确实很是繁琐无聊。
索性自己写个脚本，这样一接手新的服务器就能自动配置，省下时间来好好折腾别的。

功能

目前适用环境：CentOS 5+、Ubuntu、Debian

  1. 显示系统信息
  2. 修改源为国内阿里云源镜像（也可修改参数配置其他源）
  3. 创建指定用户、创建Home目录、指定Shell、添加到 sudoers （可修改参数）
  4. 下载.bashrc、.vimrc 配置工作环境（来自博主自己）
  5. 安装Shadowsocks 、BBR（可选、来源 https://teddysun.com/ 秋水逸冰）
  6. 配置Java、Python等（待续完善）
