一、Docker安装部署

1. 环境准备

curl  http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -o /etc/yum.repos.d/docker-ce.repo
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

　2.安装依赖包

yum install -y yum-utils device-mapper-persistent-data lvm2
yum list docker-ce.x86_64 --showduplicates | sort -r

　3. 安装docker-ce

yum install -y --setopt=obsoletes=0 
docker-ce-17.03.2.ce-1.el7.centos.x86_64 
docker-ce-selinux-17.03.2.ce-1.el7.centos.noarch

　4.启动Docker服务

systemctl daemon-reload
systemctl restart docker
docker version
docker  info

　5.配置镜像加速

阿里云Docker-hub

https://cr.console.aliyun.com/cn-hangzhou/mirrors
mkdir -p /etc/docker

tee /etc/docker/daemon.json <<-'EOF'
{
   "registry-mirrors": ["https://68rmyzg7.mirror.aliyuncs.com"]
}
EOF   
          
或者:
vim   /etc/docker/daemon.json

    {
         "registry-mirrors": ["https://68rmyzg7.mirror.aliyuncs.com"]
    }
