数据库引擎tinkerpop">1，图数数据库 引擎TinkerPop
之前简单测试了下tinkerpop。sql 数据库 ，这样更加接近线上系统使用，TinkerPop不解决数据存储的问题，需要使用扩展放到其他存储上面，通过blueprints 接口存储。
2，mysql数据库准备
使用mysql root进行操作：（创建数据库，并创建用户并赋予权限）
CREATE DATABASE tinkerpop DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
GRANT ALL PRIVILEGES ON tinkerpop.* TO tinkerpop@"%" IDENTIFIED BY "tinkerpop";
FLUSH PRIVILEGES;
