nfs卷安装到ubuntu virtualbox内的mysql docker容器失败

Question

请帮助我解决我面临的nfs卷安装问题。

我从freenas服务器安装了nfs文件共享，并将其安装在主机linux（ubuntu 14.04服务器）上

mount -t nfs -o proto=tcp xxx.xxx.x.xxx:/mnt/freenas/nmedia /mnt/media

在linux主机上，我安装了oracle virtualbox（4.3），并从主机/mnt/media （又是ubuntu 14.04服务器）安装了带有共享文件夹的linux virtualbox，其中安装了kodi-xbmc。 在此virtualbox上，我具有以下版本详细信息的docker：

root@kodixbmc:~# docker version
Client version: 1.7.1
Client API version: 1.19
Go version (client): go1.4.2
Git commit (client): 786b29d
OS/Arch (client): linux/amd64
Server version: 1.7.1
Server API version: 1.19
Go version (server): go1.4.2
Git commit (server): 786b29d
OS/Arch (server): linux/amd64

我已通过以下启动脚本将主机上的共享文件夹从主机安装到virtualbox中，并在/etc/rc.local了输入：

#!/bin/bash
echo 'Mounting Share folder to /mnt/Share'
`sudo mount -t vboxsf -o uid=$UID,gid=root media /mnt/media`

我想通过以下运行命令运行指向/mnt/media/mysql的mysql容器：

docker run -d --privileged --name=mysql -v /mnt/media/mysql/data:/var/lib/mysql -v /mnt/media/mysql/logs:/var/log/mysql mgmttools:443/phani/mysql:latest

当我尝试通过以下方式连接到终端时，mysql恶魔未启动

docker run -it --privileged --name=mysql -v /mnt/media/mysql/data:/var/lib/mysql -v /mnt/media/mysql/logs:/var/log/mysql mgmttools:443/phani/mysql:latest /bin/bash

然后使用/usr/bin/mysqld_safe自己执行mysqld，它可以写入日志文件，下面是日志文件的内容

任何与卷装载相关的问题的经验法则是同步文件服务器用户和在Docker容器中运行进程的关键用户的用户ID和组ID。 我可以通过将docker容器的mysql用户和mysql组的uid和gid与我的freenas用户的uid和gid同步来解决我的问题。
