Procedure
Check and run docker container again.

Summary
- ldd can be used to check if mysqld is missing "libxxx.so" file.Then you can install or copy directly into "/usr/lib64" directory.
- There're many errors in my installation procedure due to inappropriate parameters.
- Because of the vagrant,all the shared directories in docker contains also has the 777 privilege what cause the world-writable issue.
- Since MySQL 5.7,password of root@localhost must be changed while first login.Otherwise,you can do nothing at all.
