ubuntu24.04安装docker和docker-compose

安装 Docker（完整步骤）

bash

# 更新系统
sudo apt update && sudo apt upgrade -y

# 安装依赖
sudo apt install -y \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg \
    lsb-release

# 添加 Docker GPG 密钥
sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg

# 添加 Docker 软件源（使用国内镜像）
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://mirrors.aliyun.com/docker-ce/linux/ubuntu \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

# 安装 Docker
sudo apt update
sudo apt install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

# 启动 Docker
sudo systemctl start docker
sudo systemctl enable docker

# 添加用户到 docker 组
sudo usermod -aG docker $USER
newgrp docker

# 验证安装
docker --version

安装 Docker Compose

bash

# 下载最新版 Docker Compose
sudo curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

# 添加执行权限
sudo chmod +x /usr/local/bin/docker-compose

# 创建符号链接
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

# 验证安装
docker-compose --version

配置镜像加速器

bash

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<EOF
{
  "registry-mirrors": [
    "https://docker.mirrors.ustc.edu.cn",
    "https://hub-mirror.c.163.com",
    "https://registry.docker-cn.com"
  ]
}
EOF

sudo systemctl daemon-reload
sudo systemctl restart docker

以上完成验证如下图

 

如果在下载docker-compose失败的话，可以多试几次，如下图，或者你告诉我 我把对应版本的docker-compose的包发给你（有时候在国nei环境要多等一会73M下载57分钟，是要有足够的耐心，请理解，当好牛马）
