修改软件源
-
Ubuntu 默认的软件源是境外的,速度上会有些问题,我们可以在「Software & Updates」(软件和更新)中选择国内的镜像。
-
还可以直接修改配置文件 https://developer.aliyun.com/mirror/ubuntu?spm=a2c6h.13651102.0.0.775b1b11o2W9u7
更新系统软件
sudo apt update
sudo apt upgrade
sudo apt autoremove

ssh服务
- 安装
sudo apt update
sudo apt install openssh-server
ssh免密登录失败
-
win10产生密钥
-
Ubuntu 添加密钥到 authorized_keys
-

git
- 安装
sudo apt update
sudo apt install git
sudo apt install cmake
- 配置
静态IP
- VirtualBox安装完Ubuntu后,默认应该是开启一块网卡,连接方式根据宿主电脑的连接方式来(如果物理机是通过有线上网,那么需要使用NAT网络连接方式,如果是无线网络,那么需要使用桥接方式上网),该网卡负责虚拟机的上网。
-
查看网卡名字
ifconfig
-
sudo vim /etc/netplan/01-network-manager-all.yaml
# Let NetworkManager manage all devices on this system network: version: 2 renderer: NetworkManager #network: # ethernets: # enp0s3: # dhcp4: no # addresses: [192.168.1.103/24] # gateway4: 192.168.0.1 # nameservers: # addresses: [114.114.114.114, 8.8.8.8] # version: 2
- sudo netplan apply
