离线docker安装mysql 5.7

离线安装docker

1、环境:docker一般安装在linux7(内核3.1)以上。
2、安装包下载：
tgz
https://download.docker.com/linux/static/stable/x86_64/
rpm
https://download.docker.com/linux/centos/7/x86_64/stable/Packages/
3、安装
tar -xvf docker-18.06.1-ce.tgz
cp docker/* /usr/bin/
dockerd &
(官方参考文档：https://docs.docker.com/install/linux/docker-ce/binaries/#install-static-binaries)
4、测试
[root@centos75-1 ~]# docker -v
Docker version 18.06.1-ce, build e68fc7a

docker安装mysql 5.7

内网无法联网，所以在外网虚拟机把image打包出来丢到内网跑
