2、版本号(非常重要) v 1.6.7.4

3、相关表的配置信息 schema.xml (需包含表的配置信息，mysql的连接驱动是JDBC还是native方式)

select user()

rule.xml (涉及到的路由函数)

XXX_ID mod-long

<function name="mod-long" class="io.mycat.route.function.PartitionByMod">
   <property name="count">64</property>
</function>

server.xml(可选)

8066 9066 0 0.0.0.0 2048 1 utf8mb4 2 16 32 7200000 300 1000 104857600
