ubuntu系统基础配置

---

一、网络配置

安装完系统后，会出现这样的界面：

输入之前设定的密码即可。

登录成功。

切换root登录。

sudo -i
输入你的密码即可登录root
修改sshd_config
使其可以使用root直接登录
vim /etc/ssh/sshd_config
PermitRootLogin yes
systemctl restart sshd

修改root密码

修改时区

timedatectl set-timezone Asia/Shanghai
timedatectl -a
timedatectl show

修改域名

hostnamectl hostname 域名
bash

修改网络配置

vim /etc/netplan/*
network:
  version: 2
  renderer: networkd
  ethernets:
    ens33:
      dhcp4: no
      dhcp6: no
      addresses: [172.16.1.30/16]
      routes:
        - to: default
          via: 172.16.16.1
      nameservers:
        addresses: [218.2.135.1, 8.8.8.8]

netplan apply重启网络

二、修改镜像源

vim /etc/apt/sources.list
deb https://mirrors.aliyun.com/ubuntu/ jammy main restricted universe multiverse
deb-src https://mirrors.aliyun.com/ubuntu/ jammy main restricted universe multiverse

deb https://mirrors.aliyun.com/ubuntu/ jammy-security main restricted universe multiverse
deb-src https://mirrors.aliyun.com/ubuntu/ jammy-security main restricted universe multiverse

deb https://mirrors.aliyun.com/ubuntu/ jammy-updates main restricted universe multiverse
deb-src https://mirrors.aliyun.com/ubuntu/ jammy-updates main restricted universe multiverse

# deb https://mirrors.aliyun.com/ubuntu/ jammy-proposed main restricted universe multiverse
# deb-src https://mirrors.aliyun.com/ubuntu/ jammy-proposed main restricted universe multiverse

deb https://mirrors.aliyun.com/ubuntu/ jammy-backports main restricted universe multiverse
deb-src https://mirrors.aliyun.com/ubuntu/ jammy-backports main restricted universe multiverse

修改成ali源。

阿里云仓库地址：https://opsx.alibaba.com/mirror    https://developer.aliyun.com/mirror/
