docker离线安装
有时候docker运行环境连不了互联网,怎么安装呢?这里介绍docker 离线安装方法,非常简单,只需要一个下载包和几个命令就能搞好!
1、去官网下载docker 安装二进制包,选择适合自己的版本。这里下载的是docker-19.03.9.tgz,在centos7中安装(cento6无法使用,提示linux版本内核版本太低)
下载地址:https://download.docker.com/linux/static/stable/x86_64/
2、复制docker-19.03.9.tgz到服务器上,解压:tar xzvf docker-19.03.9.tgz
3、进入docker目录复制所有文件到/usr/bin目录下,目的/user/bin是环境变量目录,在路径下都可以运行docker命令
ls -l docker
cp docker/* /usr/bin/
[root@localhost local]# tar xvf docker-19.03.9.tgz
docker/
docker/docker-init
docker/runc
docker/docker
docker/docker-proxy
docker/containerd
docker/ctr
docker/dockerd
docker/containerd-shim
[root@localhost local]# ls -l docker
