Ubuntu 安装源及初始配置

一、 配置常用 Ubuntu 安装的阿里源：

% cd /etc/apt % sudo vi sources.list # 编辑完成后需要执行： % sudo apt update # 18.04 版本替换为以下内容： 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-backports main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports 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 # 20.04 版本替换为以下内容： deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse # 22.04 版本替换为以下内容： deb http://mirrors.aliyun.com/ubuntu/ jammy main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ jammy main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ jammy-security main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ jammy-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ jammy-updates main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ jammy-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ jammy-proposed main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ jammy-proposed main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ jammy-backports main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ jammy-backports main restricted universe multiverse 

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 ssh

2. 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:ALL

2. 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：

% sudo vi /etc/systemd/logind.conf HandleLidSwitch=ignore # 重启服务： % sudo service systemd-logind restart

2.2 安装远程 vnc

% sudo apt install vino dconf-editor # 进行系统 settings 中将共享（share）中的桌面共享打开，并启用自动登录 # 对 MacOS 等 vnc 客户端，需要运行 dconf-editor # 进入：org -> gnome -> desktop -> remote access -> require encrytion 选择关闭 # 关闭 Ubuntu 桌面版动画，使应用程序菜单不再卡顿 % gsettings set org.gnome.desktop.interface enable-animations false

3. GPU 显示器安装

# Nvidia GPU 安装 % sudo ./NVIDIA-Linux-x86_64-510.85.02.run -z --dkms --no-opengl-files --no-cc-version-check
