docker重啟後啟動失敗Failed to start Docker Application Container Engine.

剛剛弄了docker重啟了一下，本來啟動得好好的，重啟系統後就不行了
一直給我報錯
最開始是這樣的

給我提示 msg="Error starting daemon: Error loading key file /etc/docker...ON input\n"
我開始也沒有在意，一直在用網上的方法試什麼刪除/var/run/docker.sock，或者是刪除rm -rf /var/lib/docker/
最著不住的是居然看見有人說再重啟系統後就能成功，簡直是。。。。
可怕！！
當然以上都沒有成功。。。
然後報錯資訊突然變了

我去這次顯示得如此清楚，以前的那個我就沒有注意看。。。
解決方法：當然是刪除key.json
[[email protected] run]# rm /etc/docker/key.json rm: remove regular empty file ‘/etc/docker/key.json’? y [[email protected] run]# systemctl start docker.service
本來我以為我寫完了，然後我發現我另外幾臺刪了也啟動不了。。。
請把rm -rf /var/lib/docker/一併刪除
[[email protected] ~]# rm /etc/docker/key.json
rm: remove regular empty file ‘/etc/docker/key.json’? y
[[email protected] ~]# systemctl restart docker
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.
[[email protected] ~]# rm -rf /var/lib/docker/
[[email protected] ~]# systemctl restart docker
解決問題，看來以後得多注意下細節
