在OS X上.
我试图通过boot2docker在docker容器中运行mysql,通过在主机上挂载volume / var / lib / MysqL,这样我就可以拥有持久的MysqL数据.
我计划将来使用仅数据容器,但是现在我正在尝试使用此选项.
我使用以下命令来运行容器：
docker run -v / Users / yash / summers / db：/ var / lib / MysqL -i -t’image name’
/ Users / yash / summers / db文件夹已经存在.
我正面临着这方面的问题.使用命令行,我能够访问目录,创建/删除新文件,但是当我运行时
服务MysqL启动,我收到以下错误：

在过去的两天里,我试图解决这个问题,经历了很多页面,如this,this和this.
根据我的理解,这些页面上列出了一些解决方法,包括更改uid和guid,但我认为它们没有得到很好的解释.
任何人都可以向我解释一个详细的解决方法.
更新1：我尝试使用仅数据容器,仍然面临同样的问题.
如果我不使用任何-v或–volumes-from选项,我可以运行一切正常,所以我认为在MysqL服务器中没有问题.
更新2：
用于创建仅数据容器的Dockerfile：
FROM ubuntu
RUN mkdir /var/lib/MysqL
VOLUME /var/lib/MysqL
>解决方案#1.使用Dockerfile
(我不喜欢它因为我更喜欢Docker Hub中的官方图像而没有任何更改)
将RUN usermod -u 1000 MysqL添加到Docker文件中以设置ID 1000
对于用户“MysqL”(与docker-machine内部相同的ID).
>解决方案#2.用my.cnf.
我仍然使用自己的配置我更喜欢这个解决方案.我们alredy拥有ID为1000的root用户,因为我们
可以用这个用户运行MysqL：
> my.cnf
主行是user = root(你可以使用sed只更改文件中的这一行.我更喜欢mount all file)
