一、引言

本章主要讲述在Linux发行版离线安装Docker。适用于欧拉、麒麟、RHEL红帽、CentOS等，部署方式也适用于x86-64、ARM64架构服务器（区别在于安装的包，步骤是一致的）。

二、详解

这里以x86-64架构作为示例讲解。

1、离线安装包下载

下载地址1： https://download.docker.com/linux/static/stable/x86_64/
下载地址2：https://mirrors.aliyun.com/docker-ce/linux/static/stable/x86_64/

2、开始安装

# 解压；并安装至/usr/local/bin目录
>> cd /root; tar -zxvf docker-27.4.1.tgz 
>> install -d -m 0755 /usr/local/bin; install -m 0755 ./docker/* /usr/local/bin/

# 创建配置目录、数据目录
>> mkdir -p /etc/docker /data/docker
>> chmod 755 /data/docker

# 编辑daemon.json
>> cat > /etc/docker/daemon.json << EOF
{
  "registry-mirrors": [
    "https://b4pkzo6x.mirror.aliyuncs.com", 
    "https://docker.1panel.live"
  ],
  # 地址池
  "default-address-pools": [
    {
      "base": "10.209.0.0/16",
      "size": 24
    }
  ],
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "100m",
    "max-file": "3"
  },
  # 数据目录
  "data-root": "/data/docker",
  "live-restore": true,
  "iptables": true
}
EOF

# 启动前校验配置
>> /usr/local/bin/dockerd --validate --config-file=/etc/docker/daemon.json

# 配置systemd管理
>> cat > /etc/systemd/system/docker.service << EOF
