1.安装docker步骤

rm -fr /etc/yum.repos.d/local.repo
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
wget -O /etc/yum.repos.d/docker-ce.repo https://mirrors.ustc.edu.cn/docker-ce/linux/centos/docker-ce.repo
sed -i 's#download.docker.com#mirrors.tuna.tsinghua.edu.cn/docker-ce#g' /etc/yum.repos.d/docker-ce.repo
yum install docker-ce -y
systemctl start docker
cat > /etc/docker/daemon.json <<EOF
{
  "registry-mirrors": ["https://registry.docker-cn.com"]
}
EOF 
systemctl restart docker

2.下载nginx镜像

docker run --name nginx -p 80:80 -d nginx
docker ps
docker logs -f nginx
