6、返回服务器，新建 /etc/docker 目录

已有就不用创建了

mkdir -p /etc/docker

7、将下载的镜像加速器加到 daemon.json 配置文件中；

[root@localhost docker]# sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://ofads5sdl5c.mirror.aliyuncs.com"]
}
EOF

8、重新加载配置文件+重启docker服务

#重新加载配置文件
systemctl daemon-reload

#重启docker服务
systemctl restart docker

9、重新拉取镜像
