1. 备份源文件
   sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup
2. 编辑/etc/apt/sources.list

deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse

# 以下安全更新软件源包含了官方源与镜像站配置，如有需要可自行修改注释切换
deb http://security.ubuntu.com/ubuntu/ focal-security main restricted universe multiverse
# deb-src http://security.ubuntu.com/ubuntu/ focal-security main restricted universe multiverse

# 预发布软件源，不建议启用

Ubuntu server 24

1. 备份源文件

sudo cp /etc/apt/sources.list.d/ubuntu.sources  /etc/apt/sources.list.d/ubuntu.sources.bak

2. 更换镜像源

# 以下两种方式二选一
## 方式一
sudo echo "Types: deb
URIs: http://mirrors.aliyun.com/ubuntu/
Suites: noble noble-updates noble-security
Components: main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg" > /etc/apt/sources.list.d/ubuntu.sources

## 方式二
sudo vim /etc/apt/sources.list.d/ubuntu.sources
# 输入阿里云
Types: deb
URIs: http://mirrors.aliyun.com/ubuntu/
Suites: noble noble-updates noble-security
Components: main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg

# 清华
Types: deb
URIs: http://mirrors.tuna.tsinghua.edu.cn/ubuntu/
Suites: noble noble-updates noble-security
Components: main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg

3. 执行以下命令
   sudo apt-get update
sudo apt-get upgrade

4.开启SSH

# ssh安装
sudo apt install openssh-server
# 开启ssh服务
sudo systemctl start ssh
# 开机自动启动ssh
sudo systemctl enable ssh
# 设置好后重启
reboot
# 查看ssh是否自动启动
sudo systemctl status ssh

# ftp
sudo apt install vsftpd

sudo systemctl start vsftpd

sudo systemctl enable vsftpd

sudo systemctl status vsftpd

Ubuntu扩容

Ubuntu 安装 Docker

1. 卸载原有版本
   sudo apt-get remove docker docker-engine docker-ce docker.io
sudo rm -rf /var/lib/docker
dpkg -l | grep docker
sudo apt-get purge docker-ce
2. 更新索引包
   sudo apt-get update
3. 安装添加使用HTTPS传输软件包
   sudo apt-get -y install apt-transport-https ca-certificates curl software-properties-common
   4.添加软件源GPG密钥(中科大）
   curl -fsSL https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu/gpg | sudo apt-key add -
   5.向source.list添加Docker软件源
   sudo add-apt-repository "deb [arch=amd64] https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu $(lsb_release -cs) stable"
   6.更新索引包、且安装
   sudo apt-get update
sudo apt-get install docker-ce
   7.启动后台服务
   sudo service docker start
4. 查看Docker和Docker compose版本
   docker version
docker compose version
5. 镜像加速

sudo tee /etc/docker/daemon.json <<EOF
{
	"registry-mirrors": ["https://hub.uuuadc.top", "https://docker.anyhub.us.kg", "https://dockerhub.jobcher.com", "https://dockerhub.icu", "https://docker.ckyl.me", "https://docker.awsl9527.cn"]
}
EOF

sudo systemctl daemon-reload
sudo systemctl restart docker

10. 重启

systemctl stop docker
systemctl daemon-reload
systemctl start docker
