Docker 安装使用

1. 下载

下载地址：Index of linux/static/stable/x86_64/

下载好后，将文件docker-18.06.3-ce.tgz用WinSCP等工具，上传到不能外网的linux系统服务器

2. 安装

解压后的文件夹docker中文件如下所示：

将docker中的全部文件，使用下边命令，复制到/usr/bin

cp ./docker/* /usr/bin

创建docker.service文件

cd /etc/systemd/system/
touch docker.service

编辑docker.service文件

注意，将其中的ip地址，改成您的服务器地址，其它参数不用改。
