下载Docker安装包
https://download.docker.com/linux/static/stable/x86_64/
二、上传解压
tar -xvf docker-29.1.2.tgz
三、将解压出来的docker文件内容移动到 /usr/bin/ 目录下
四、将docker注册为service
vim /etc/systemd/system/docker.service
[Unit]Description=Docker Application Container EngineDocumentation=https://docs.docker.comAfter=network-online.target firewalld.serviceWants=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 dockerExecStart=/usr/bin/dockerdExecReload=/bin/kill -s HUP $MAINPID# Having non-zero Limit*s causes performance problems due to accounting overhead# in the kernel.

五、添加文件权限并启动docker
chmod +x /etc/systemd/system/docker.service
六、重载unit配置文件
七、启动Docker
八、设置开机自启
systemctl enable docker.service
九、验证
systemctl status docker #查看Docker状态
docker version #查看Docker版本
