[英]Trying a quick cluster deployment with Docker:Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
我發現 DolphinDB 現在支持使用 docker 容器進行快速集群部署,我按照 github 上的指南: https : //github.com/dolphindb/Tutorials_CN/blob/master/docker_deployment.md使用 DolphinDB Docker 包部署集群。 但是我遇到了一個問題。 我查看了任何其他問題,但找不到自己的解決方案。
這是問題所在:
xllu@xllu-OptiPlex-7060:~/DolphinDB-Docker-Compose/Dockerbuild$ docker -v
Docker version 18.09.3, build 774a1f4
xllu@xllu-OptiPlex-7060:~/DolphinDB-Docker-Compose/Dockerbuild$ docker-compose --version
docker-compose version 1.24.0, build 0aa59064
xllu@xllu-OptiPlex-7060:~/DolphinDB-Docker-Compose/Dockerbuild$ docker build -t ddb:latest ./
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
我嘗試重新啟動docker:
xllu@xllu-OptiPlex-7060:~/DolphinDB-Docker-Compose/Dockerbuild$ sudo service docker restart
Job for docker.service failed because the control process exited with error code.
See "systemctl status docker.service" and "journalctl -xe" for details.
然后我檢查了這個:
xllu@xllu-OptiPlex-7060:~/DolphinDB-Docker-Compose/Dockerbuild$ systemctl status docker.service

您可以嘗試使用sudo rm -rf /var/lib/docker
刪除/var/lib/docker
sudo rm -rf /var/lib/docker
並嘗試重新啟動 docker 嗎?
