环境以及版本
- Ubuntu-22.04
- wsl2 （Windows sub Linux version 2）
- Docker 24.0.7
1. 下载
2. 解压安装包
tar -zxvf docker-24.0.7.tgz
3. 将 docker 可执行文件复制到 /usr/bin/ 目录下
cp docker/* /usr/bin/
可执行文件包含：containerd containerd-shim containerd-shim-runc-v2 ctr docker dockerd docker-init docker-proxy runc
4.编辑docker.service 设置开机启动
编辑 docker.service 文件vim /usr/lib/systemd/system/docker.service
[Unit] Description=Docker Application Container Engine Documentation=https://docs.docker.com After=network-online.target firewalld.service containerd.service Wants=network-online.target [Service] Type=notify # the default is not to use systemd for cgroups because the delegate issues still # exists and systemd currently does not support the cgroup feature set required # for containers run by docker ExecStart=/usr/bin/dockerd --exec-opt native.cgroupdriver=systemd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock ExecReload=/bin/kill -s HUP $MAINPID TimeoutSec=0 RestartSec=2 Restart=always # Note that StartLimit* options were moved from "Service" to "Unit" in systemd 229. # Both the old, and new location are accepted by systemd 229 and up, so using the old location # to make them work for either version of systemd.

TasksMax=infinity # 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 OOMScoreAdjust=-500 [Install] WantedBy=multi-user.target
启动程序，并设置开机自动启动，systemctl restart docker && systemctl enable docker.service
5. 安装完成，验证结果
systemctl status docker
docker version
其实可以看到，以离线的方式安装 docker 很简单，而且相比较用 yum 那种在线一键安装方式，离线安装可以巩固下 Linux 的相关知识，比如 可执行文件要放 /usr/bin 目录下 、Service 如何去配置 、systemctl 命令。
建议进阶玩家可以多试试离线安装的方式。
