二、安装以下常用工具
1. 安装 ssh，ifconfig 等常用网络软件
% sudo apt install net-tools ssh2. 安装 gcc 等常用开发库
% sudo apt install build-essential
三、常用配置命令
1. 添加用户及设置
% useradd [用户名]
% sudo vi /etc/group # 将用户增加到合适组中，如 sudo,admin
% sudo vi /etc/sudoers # 设置 sudo 时不需要输入命令
%sudo ALL=(ALL:ALL) NOPASSWD:ALL
[用户名] ALL=(ALL:ALL) NOPASSWD:ALL2. 设置远程操作
# 开机默认进入命令行模式
% sudo systemctl set-default multi-user.target
# 开机默认进入图形用户界面
% sudo systemctl set-default graphical.target 2.1 合上笔记本盖子不休眠，取消 #HandleLidSwitch=suspend注释（即删除#号），然后将suspend改为ignore：
