離線安裝docker
1、環境:docker一般安裝在linux7(內核3.1)以上。
2、安裝包下載：
tgz
https://download.docker.com/linux/static/stable/x86_64/
rpm
https://download.docker.com/linux/centos/7/x86_64/stable/Packages/
3、安裝
tar -xvf docker-18.06.1-ce.tgz
cp docker/* /usr/bin/
dockerd &
(官方參考文檔：https://docs.docker.com/install/linux/docker-ce/binaries/#install-static-binaries)
4、測試
[root@centos75-1 ~]# docker -v
Docker version 18.06.1-ce, build e68fc7a
docker安裝mysql 5.7
內網無法聯網，所以在外網虛擬機把image打包出來丟到內網跑
