1. 移除舊版本

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

2. 安裝工具以及設(shè)置docker倉庫（不用原生倉庫太慢）

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

3. 安裝docker

sudo yum makecache fast

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

4. 啟動docker

sudo systemctl start docker

systemctl enable docker

5.騰訊云配置鏡像加速器

sudo mkdir -p /etc/docker
vi /etc/docker/daemon.json
{
   "registry-mirrors": [
   "https://mirror.ccs.tencentyun.com"
  ]
}

sudo systemctl daemon-reload
sudo systemctl restart docker
