解决
保证如下3个文件都存在，且时间一样，run目录下的docker.sock文件有docker属性：
1 2 3 4 5 6 7 8 9 10 11 | ll /run/containerd/containerd.sock ll /var/run/docker.sock ll /run/docker.sock ln -sf /run/docker.sock /var/run/docker.sock systemctl status docker systemctl status docker.socket systemctl start docker systemctl start docker.socket |
