一、说明
docker 一般安装在linux7以上，内核3.1以上。
查看内核
uname -a
lsb_release -a
安装文件：docker-19.03.8.tgz
二、下载地址
tgz
https://download.docker.com/linux/static/stable/x86_64/
rpm
https://download.docker.com/linux/centos/7/x86_64/stable/Packages/
CentOS8 离线安装 docker-19 rpm版，卸载、启动、停止、自启动
https://blog.csdn.net/haveqing/article/details/105277605
三、安装
如果系统上已经有docker了，请先卸载
上传文件，解压
[root@dev1 opt]#
tar -xvf docker-19.03.8.tgz
docker/
docker/containerd
docker/docker
docker/ctr
docker/dockerd
docker/
runc
docker/docker-proxy
docker/docker-init
docker/containerd-shim
复制
[root@dev1 opt]# cp docker/* /usr/bin/
cp：是否覆盖’/usr/bin/runc’？
n
/usr/bin/runc已经有了，两个版本几乎一致，不覆盖了。
RunC 是一个轻量级的工具，它是用来运行容器的，只用来做这一件事，并且这一件事要做好。我们可以认为它就是个命令行小工具，可以不用通过 docker 引擎，直接运行容器。事实上，runC 是标准化的产物，它根据 OCI 标准来创建和运行容器。而 OCI(Open Container Initiative)组织，旨在围绕容器格式和运行时制定一个开放的工业化标准。
四、启动服务

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
如果报这句，是dockerd服务没启，启动：dockerd &
六、停止服务
使用kill（这种方式安装的，目前没找到好办法），一般也不用停止
[root@dev1 opt]#
ps -ef|grep docker
root 6003 4219 0 23:34 pts/0 00:00:00 dockerd
root 6012 6003 0 23:34 ? 00:00:00 containerd –config /var/run/docker/containerd/containerd.toml –log-level info

[root@dev1 opt]#
kill

七、卸载
停止服务，把复制到/usr/bin下的7个文件删除了就可以了。
rm -rf /run/docker
