# 备份当前损坏的文件
sudo mv /etc/apt/sources.list /etc/apt/sources.list.bak

# 重新生成标准源文件（使用阿里云镜像）
sudo tee /etc/apt/sources.list > /dev/null << 'EOF'
deb http://mirrors.aliyun.com/ubuntu/ jammy main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ jammy-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ jammy-backports main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ jammy-security main restricted universe multiverse
EOF
4 、安装必要的软件包
1
sudo apt install -y apt-transport-https ca-certificates curl software-properties-common
5、 添加阿里云（docker）GPG密钥管理
1
2
3
sudo curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -

#curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg #docker的官方GPG密钥
6、 进入到/etc/apt/sources.list.d目录，添加软件源
1
cd /etc/apt/sources.list.d
7、 添加软件源：在/etc/apt/sources.list.d目录下的docker.list文件中添加阿里云的镜像下载源（使用官网的）
1
2
sudo echo "deb [arch=amd64] https://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable" > docker.list
#sudo echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] #https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee #/etc/apt/sources.list.d/docker.list > /dev/null
8、更新软件源
1
sudo apt update
9、docker ce安装
1
sudo apt install docker-ce docker-ce-cli containerd.io docker-compose-plugin -y
10、启动Docker并设置开机自启
1
2
sudo systemctl start docker
sudo systemctl enable docker
11、验证安装
1
sudo docker run hello-world
12、如果出错
1

3
sudo systemctl enable docker
Synchronizing state of docker.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable docker
13、报错请换源，通常在 /etc/docker/daemon.json

{
    "registry-mirrors": [
            "https://registry.docker-cn.com",
             "https://docker.m.daocloud.io",           
             "https://dockerpull.org",            
             "https://dockerpull.com"
    ]
}

二、📦 安装 Docker Compose

1、下载Docker Compose二进制文件 直接从GitHub发布页下载稳定版本的Docker Compose。鉴于国内网络，如果直接下载较慢，可以多尝试几次，或者考虑使用第三方镜像源。
1
sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose  #此版本可以直接下载，用更新的版本推荐使用国内镜像

请注意，版本号（此例中为2.40.2）可能会更新。你可以查看Docker Compose的GitHub发布页以获取最新的稳定版本号

三、🚀 配置国内镜像加速器(需要自行获取加速器地址)

为了进一步提升后续拉取Docker镜像的速度，强烈建议你配置一个国内镜像加速器。

1、修改Docker守护进程配置，编辑Docker的配置文件（通常是/etc/docker/daemon.json）。如果文件不存在，可以新建一个。
1
sudo vim /etc/docker/daemon.json
2、例如，使用中科大镜像，配置文件内容如下：
1
2
3
{
  "registry-mirrors": ["https://docker.mirrors.ustc.edu.cn"]
}
3、重启Docker服务 ，让配置生效：
1
2
sudo systemctl daemon-reload
sudo systemctl restart docker
4、授予执行权限 下载完成后，需要给二进制文件添加可执行权限
1
sudo chmod +x /usr/local/bin/docker-compose
5、验证安装 ，检查Docker Compose是否安装成功：
1
docker-compose --version

说些什么吧！
