5.主从数据库管理(40分)
使用提供的两台虚拟机，在虚拟机上安装mariadb数据库，并配置为主从数据库，实现两个数据库的主从同步。配置完毕后，请在从节点上的数据库中执行“show slave status \G”命令查询从节点复制状态，将查询到的结果以文本形式提交到答题框。

6.读写分离数据库管理(40分)
使用提供的虚拟机与软件包，基于上一题构建的主从数据库，进一步完成Mycat读写分离数据库的配置安装。需要用的配置文件schema.xml文件如下所示（server.xml文件不再给出）： select user() 配置读写分离数据库完毕后，使用netstat -ntpl命令查询端口启动情况。最后将netstat -ntpl命令的返回结果以文本形式提交到答题框。
Mycat & Mysql1 & Mysql2都执行以下操作：
-

一些参数注释：
sqlMaxLimit 配置默认查询数量
database 为真实数据库名
balance="0" 不开启读写分离机制，所有读操作都发送到当前可用的writeHost上
balance="1" 全部的readHost与stand by writeHost参与select语句的负载均衡，简单来说，当双主双从模式（M1->S1，M2->S2，并且M1与M2互为主备），正常情况下，M2、S1、S2都参与select语句的负载均衡
balance="2" 所有读操作都随机的在writeHost、readhost上分发
balance="3" 所有读请求随机地分发到wiriterHost对应的readhost执行，writerHost不负担读压力，注意balance=3只在1.4及其以后版本有，1.3版本没有
writeType="0" 所有写操作发送到配置的第一个writeHost，第一个挂了需要切换到还生存的第二个writeHost，重新启动后已切换后的为准，切换记录在配置文件dnindex.properties中
writeType="1" 所有写操作都随机的发送到配置的writeHost
7.Zookeeper集群(40分)

8.Kafka集群(40分)
使用提供的三台虚拟机和软件包，完成Kafka集群的安装与配置，配置完成后，在相应的目录使用 ./kafka-topics.sh --create --zookeeper 你的IP:2181 --replication-factor 1 --partitions 1 --topic test创建topic，将输入命令后的返回结果以文本形式提交到答题框。
- 将kafka_2.11-1.1.1.tgz上传至三个节点：（可以在上体的基础上做kafka，因为kafka依赖于zookeeper）
Zookeeper1:
-
[

# tar -zvxf kafka_2.11-1.1.1.tgz

把broker.id=

9.应用商城系统(40分)
继续使用上题的三台虚拟机，使用提供的软件包，基于集群应用系统部署。部署完成后，进行登录，（订单中填写的收货地址填写自己学校的地址，收货人填写自己的实际联系方式）最后使用curl命令去获取商城首页的返回信息，将curl http://你自己的商城IP/#/home获取到的结果以文本形式提交到答题框。
- 将所需的zookeep，kafka和gpmall-repo的包上传到mall虚拟机（按题目要求的答案，其实单节点也一样，推荐单节点部署，集群部署，看大家是否需要，需要的话评论一下，我到时候更新集群部署）：
