第一步确定你的普罗米修斯是如何建立1，是通过容器

ubuntu@10-7-127-87:~$ docker ps
CONTAINER ID   IMAGE                              COMMAND                  CREATED      STATUS                PORTS                                               NAMES

第二部进入你的容器，

docker exec -it b21fc9bc9a5e /bin/bash

然后进入
b21fc9bc9a5e:/usr/share/grafana$ cd /usr/share/grafana/bin/
b21fc9bc9a5e:/usr/share/grafana/bin$ ./grafana-cli admin reset-admin-password shitou521
