docker yum裝docker-ce啟動失敗
1、相關版本資訊： 作業系統版本和docker版本如下：
[root@localhost_02 ~]# cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core)
[root@localhost_02 ~]# rpm -qa|grep docker
docker-ce-cli-18.09.4-3.el7.x86_64
docker-ce-18.09.4-3.el7.x86_64
2、下載docker 映象：並通過yum安裝：
curl https://download.docker.com/linux/centos/docker-ce.repo -o /etc/yum.repos.d/docker.repo
yum makecache fast
yum isntall -y docker-ce
3、啟動時報錯： systemctl start docker
[root@localhost_02 ~]# systemctl start 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.
4、通過 systemctl status docker.service 檢視,發現並沒有什麼錯誤資訊
也可以通過 dockerd 來檢視錯誤資訊
5、那麼只好去檢視系統日記裡： tail -n300 /var/log/message

註釋：上面 error 標紅的字型:注意到 mkfs ,然後手動執行下;
[root@localhost_02 ~]# mkfs.xfs -m crc=0,finobt=0 /dev/mapper/docker-8:3-67789151-base
unknown option -m finobt=0
Usage: mkfs
提示 -m 引數不存在; man mkfs.xfs 發現沒有 -m 引數;
可能是版本太低的原因： yum update xfsprogs
然後再次執行：mkfs.xfs -m crc=0,finobt=0 /dev/mapper/docker-8:3-67789151-base
[root@localhost_02 ~]# mkfs.xfs -m crc=0,finobt=0 /dev/mapper/docker-8:3-67789151-base

5、再次啟動：發現啟動成功了;
[root@localhost_02 ~]# systemctl start docker.service
[root@localhost_02 ~]# ps aux |grep docker
