MySQL数据挂载到主机出错？
如果不挂载主机，则运行成功，挂载执行命令如下所示：
docker run -d -p 3306:3306 -v /data:/var/lib/mysql image
执行后，在/data中会出现如下文件列表：
93a2e8e96e0a.err ibdata1 ib_logfile0 ib_logfile1
其中93*.err内容如下起所示：

这个跟挂载没关系，挂载用数据卷命令-v就完了，你这个属于image有问题，重新pull吧。

但是我 不用-v 命令的时候， mysql 能够启动的。。。

你这个image是官方的还是自己做得？/var/lib/mysql在container里存在么？你这个还想是mysql没起来，也有可能是mysql没有权限访问host上mount的volume，结果导致mysql start failure.

@devopsify 你好 ， images 是自己做的， /var/lib/mysql在container存在的,并且里面一些生成的文件也同步到/data了 。而且我host上/data文件都改成777了。
image dockerfile:
<pre>FROM ubuntu
ENV DEBIAN_FRONTEND noninteractive
RUN apt-get update && apt-get -y upgrade
RUN apt-get install -y mysql-server
RUN service mysql start &&\
mysql -e "grant all privileges on <span>.<span> to 'root'@'%' identified by 'root';" &&\
mysql -e "grant all privileges on <span>.<span> to 'root'@'localhost' identified by 'root';" &&\
mysql -u root -proot -e "show databases;"
ADD my.cnf /etc/mysql/my.cnf
ADD start.sh ./start.sh
RUN chmod +x ./start.sh
EXPOSE 3306
CMD </pre>

不知道你start.sh里面内容，还有你不应该run apt-get upgrade

docker run -it -d -p 80:80 -v /Users/xxx/Docker/lamp/data/mysql:/var/lib/mysql -v /Users/xxx/Docker/lamp/www:/var/www/html 293ef2f50d98
我到是用 -v 方式挂载的,可结果是导致无法运行Mysql,错误代码如下:
Starting MySQL database server: mysqld . . . . . . . . . . . . . . . . . . . . . . . . . . . .[FAI failed!
尝试着连接mysql -uroot -p 却出现了如下错误:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
同时检查了 /var/lib/mysq l的权限:
drwxrwxrwx 6 root root 204 Jul 11 03:11 mysql
如果不加载此文件夹时候能正常运行,而且看到/var/lib/mysql 文件夹下有一些文件,如 mysql 文件.
但是一使用 -v 加载host目录到/var/lib/mysql的时候,从Host查看这个Mysql文件夹,却是空的.
service mysql start的时候,mysql文件夹会生成3个log 文档.
ib_logfile0 - 5.2
ib_logfile1 - 5.2
ibdata1 - 18.9
请问下,这是什么情况呢? 已经做了很多功课了,可就是找不到解决办法.
