docker建立mysql:5.7版本指定路径挂载不上。

问题遇到的现象和发生背景

初学者,在docker上练习安装mysql数据库,使用了如下命令

docker run -d --name my-mysql -p 3307:3306 -e MYSQL_ROOT_PASSWORD=123456  \ 
>-v /opt/my-docker/mysql/data:/var/liv/mysql  \
>-v /opt/my-docker/mysql/conf.d:/etc/mysql/conf.d  \
>-v /opt/my-docker/mysql/log:/var/log/mysql \
>mysql:5.7

执行结果如下:
第一,容器被建立且处于运行状态
第二,在宿主机指定目录下并未出现任何文件
第三,在volume容器卷中出现了一个mysql的匿名挂载

[root@localhost data]# docker run -d --name my-mysql -p 3307:3306 -e MYSQL_ROOT_PASSWORD=123456 -v /opt/my-docker/mysql/data:/var/liv/mysql -v /opt/my-docker/mysql/conf.d:/etc/mysql/conf.d  -v /opt/my-docker/mysql/log:/var/log/mysql mysql:5.7

执行完成以后,容器被成功建立并运行。然后尝试在用远程数据库管理软件给这个数据库新建一个test库。

然后再查看volume中的那个匿名挂载文件夹,发现多了一个test。我觉得基本就可以确定,这个匿名挂载卷就是刚才我创建的mysql的挂载。

操作环境、软件版本等信息

操作系统是centos7.5 ,mysql是5.7 ,docker是1.13.1

尝试过的解决方法

重复多次,也查了好多资料,但是和我这个情况都不太一样。具名挂载也是这个状况,可以启动运行,宿主机文件夹也被创立,但是是空的,只是会增加一个匿名挂载卷。

我想要达到的结果

指定路径挂载和具名挂载的指令可以正常执行,而不是执行后就变成匿名挂载。
初学者,希望各位多多指教,谢谢啦。
