1. linux下安装docker

for centos:

https://docs.docker.com/engine/install/centos/

卸载旧版本docker:

$ sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

使用docker仓库进行安装:

$ sudo yum install -y yum-utils

官方源:

$ sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

阿里云docker源:

$ sudo yum-config-manager \
    --add-repo \
    http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

安装docker engine:

$ sudo yum install docker-ce docker-ce-cli containerd.io

开启docker服务:

$ sudo systemctl start docker

卸载docker engine

$ sudo yum remove docker-ce docker-ce-cli containerd.io
