docker启动之后马上退出解决方法

启动mysql之后发现启动成功，但是docker ps里没有

[root@localhost shiro]# docker run -d -it -p 3306:3306 mysql:8.0

docker发现只有一个redis，mysql并没有启动成功 

[root@localhost shiro]# docker ps
CONTAINER ID   IMAGE     COMMAND                  CREATED         STATUS         PORTS                                       NAMES
bccd297f6086   redis     "docker-entrypoint.s…"   3 minutes ago   Up 3 minutes   0.0.0.0:6379->6379/tcp, :::6379->6379/tcp   cool_northcutt

解决方法：-d 后台运行 -it 交互运行 加上 /bin/bash

[root@localhost shiro]# docker run -dit -p 3306:3306 mysql:8.0 /bin/bash

成功启动

[root@localhost shiro]# docker ps
