InnoDB: You can disable Linux Native AIO by setting innodb_use_native_aio = 0 in my.cnf
140505 16:06:02 InnoDB: Fatal error: cannot initialize AIO sub-system
140505 16:06:02 [ERROR] Plugin ‘InnoDB’ init function returned error.
140505 16:06:02 [ERROR] Plugin ‘InnoDB’ registration as a STORAGE ENGINE failed.
140505 16:06:02 [ERROR] Unknown/unsupported storage engine: InnoDB

解决方案：
1.先进入 mysql （已启动的）docker 中，执行如下命令
这里使用的mysql:5.6.31 docker ，如果配置文件地址不一样请自行更改

echo "innodb_use_native_aio = 0" >> /etc/mysql/my.cnf

所有的mysql docker 都要改
2.把这批改完的mysql docker 关闭
3.启动 新创建 mysql docker, 按 1 的方法更改，如果还是无法启动，把其他的mysql docker 都关闭，就可以启动了，启动了，还是要加入 1 的配置
