离线安装 Docker 和 Docker Compose 教程

一、离线安装

（一）安装 Docker

1. 下载 Docker 安装包

访问 Docker 官方静态安装包页面：

https://download.docker.com/linux/static/stable/x86_64/Index of linux/static/stable/x86_64/

1. 解压安装包并移动文件

tar -xvf docker-27.1.0.tgz
mv docker/* /usr/bin/

1. 将 Docker 注册为 systemd 服务

编辑服务文件：

vim /etc/systemd/system/docker.service

添加以下内容：

[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service
Wants=network-online.target

[Service]
Type=notify
# ExecStart=/usr/bin/dockerd
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375  -H unix:///var/run/docker.sock
ExecReload=/bin/kill -s HUP $MAINPID
# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
LimitNOFILE=infinity
LimitNPROC=infinity
LimitCORE=infinity
# Uncomment TasksMax if your systemd version supports it.
# Only systemd 226 and above support this version.
#TasksMax=infinity
TimeoutStartSec=0
# set delegate yes so that systemd does not reset the cgroups of docker containers
Delegate=yes
# kill only the docker process, not all processes in the cgroup
KillMode=process
# restart the docker process if it exits prematurely
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s

[Install]
WantedBy=multi-user.target

1. 启动 Docker 服务

chmod +x /etc/systemd/system/docker.service
systemctl daemon-reload
systemctl start docker

1. 查看 Docker 版本和服务状态

systemctl status docker
docker -v

1. 设置开机自启

systemctl enable docker.service

---

（二）镜像保存和加载

1. 保存镜像到本地文件

docker save -o 镜像保存路径 镜像名:标签
# 示例：
docker save -o nginx.tar nginx:latest

1. 加载本地镜像文件

docker load -i 镜像文件路径
# 示例：
docker load -i nginx.tar

---

（三）安装 Docker Compose

1. 下载 Docker Compose

访问地址：

https://github.com/docker/compose/releases/download/v2.27.1/docker-compose-linux-x86_64

下载后上传至服务器：

mv docker-compose-linux-x86_64 /usr/local/bin/docker-compose

1. 添加执行权限

chmod +x /usr/local/bin/docker-compose

1. 创建软连接（可选）

ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

1. 查看版本确认安装成功

docker-compose --version
