記錄一下 折騰了一天 一臺服務器跑代碼崩了 重啓後，dockers無法使用， 啓動docker 報

sudo vim /lib/systemd/system/docker.service
ExecStart=/usr/bin/dockerd -H fd://
看了其他幾臺的配置，默認就是讀取該位置
改爲 ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock
後 sudo systemctl daemon-reload sudo systemctl start docker
報如下問題

嘗試了很多辦法
最後 還是改 ExecStart=/usr/bin/dockerd -H fd:// --containerd=/var/run/docker.sock 後 啓動後
把8883 端口的容器幹
再把 改爲 ExecStart=/usr/bin/dockerd -H fd://
sudo systemctl daemon-reload sudo systemctl start docker 重啓後 正常
