can'；t连接到docker守护进程，尽管&x27；开始

我跑

得到

systemctl status docker

但当我这么做的时候

我明白了

有人知道这里出了什么问题吗

（我确实在/var/run中看到docker.pid，但是我在/var/run中没有看到docker.sock）

进一步发现后，套接字文件位于此处 /run/docker.sock not/var/run/docker.sock

docker.socket的systemd单位文件如下所示

Client:
 Context:    default
 Debug Mode: false
 Plugins:
  app: Docker App (Docker Inc., v0.9.1-beta3)
  buildx: Build with BuildKit (Docker Inc., v0.5.1-docker)
  scan: Docker Scan (Docker Inc., v0.7.0)

Server:
ERROR: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
errors pretty printing info

不确定守护进程或客户端是否错误，以及如何修复它

---

更新：嗯，如果我创建一个从/var/run/docker.sock到/run/docker.sock的符号链接，它就会工作。不太好，但我想我会接受它

用sudo运行Docker命令。同样的结果，我的用户在Docker组中。这回答了你的问题吗？不，我在发帖前看到了。这看起来很相似，但没有帮助。嗯，如果我创建一个从/var/run/docker.sock到/run/docker.sock的符号链接，它就会工作。不太好，但我想我会接受的。
