配置phabricator需要mysql的管理员权限，如何才能使用RDS配置？

最近准备使用phabricator来做代码review，安装过程一路畅通，单到最后的时候，phabricator提示：

Setup MySQL Schema
Run the storage upgrade script to setup Phabricator's database schema.

Run this command:phabricator/ $ ./bin/storage upgrade


运行后phabricator抛出异常：

看样子大概是因为我提供的数据库用户不是root导致无法读取schema数据，请问这个问题有人遇到么？
