不需要 数据库分片时，不用配置。 但是不能没有 tableRule 元素， 否则报错。 随便写个空规则就行了。
3. 测试读写分离
a. 在 Master ， Slave1 ， Slave2 中分别查看 日志文件： mysql.log
tail -f ./log/mysql.log
b. 启动 Amoeba， 使用 Mysql GUI Tools 连接 Amoeba
执行以上几个命令。 查看日志内容。

从日志中可以看出。
在 Master mysql.log 中，只执行了 insert into 命令。
在 Slave1 中，只是复制了 insert into 命令， 是主从复制的结果
在 Slave2 中， 复制了 insert into 命令，同时还执行了 select 命令。
说明，主从分离已经成功。
