出现这些报错时是因为docker没能启动

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

给docker创建etc目录 配置文件创建

# 开机自启
systemctl enable docker

systemctl start docker
# docker 配置阿里云镜像加速
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://m3lbzk97.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

然后启动docker，执行harbor 安装文件./install.sh

即可
