执行docker ps 命令显示
[root@localhost vagrant]# docker ps
[root@localhost vagrant]# Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
执行systemctl restart docker命令显示
[root@localhost vagrant]# systemctl restart docker
Job for docker.service failed because start of the service was attempted too often. See "systemctl status docker.service" and "journalctl -xe" for details.
To force a start use "systemctl reset-failed docker.service" followed by "systemctl start docker.service" again.
执行journalctl -xe显示
执行journalctl -xe显示（空间不足）
[root@localhost vagrant]# journalctl -xe
[root@localhost vagrant]# imjournal: fopen() failed for path: '/var/lib/rsyslog/imjournal.state.tmp': No space left on device [v8.24.0-52.el7 try http://www.rsyslog.com/e/2013 ]
执行df -h显示磁盘100%
[root@localhost vagrant]# df -h
Filesystem Size Used Avail Use% Mounted on
devtmpfs 489M 0 489M 0% /dev
tmpfs 496M 4.0K 496M 1% /dev/shm
tmpfs 496M 6.7M 489M 2% /run
tmpfs 496M 0 496M 0% /sys/fs/cgroup
/dev/sda1 40G 40G 20K 100% /
tmpfs 100M 0 100M 0% /run/user/1000
可以判断出磁盘已经100%了
执行find . -type f -size +100M找出没用的文件删除为磁盘腾出空间问题就解决了
