架构图（考试时命令对就行了，只用 一台SW1和R1就够了，但为了学到东西所以练习时采用完整的部署方案）
SW1配置:
system-view
[Huawei]sysname SW1
[SW1]vlan batch 101 1001
[SW1]interface GigabitEthernet 0/0/1
[SW1-GigabitEthernet0/0/1]port link-type access
[SW1-GigabitEthernet0/0/1]port default vlan 1001
[SW1-GigabitEthernet0/0/1]quit
[SW1]interface vlan 1001
[SW1-Vlanif1001]ip address 192.168.1.2 30
[SW1-Vlanif1001]quit
[SW1]interface GigabitEthernet 0/0/2
[SW1-GigabitEthernet0/0/2]port link-type access
[SW1-GigabitEthernet0/0/2]port default vlan 101
[SW1-GigabitEthernet0/0/2]quit
[SW1]interface vlan 101
[SW1-Vlanif101]ip address 172.16.101.254 24
[SW1-Vlanif101]quit
[SW1]ip route-static 0.0.0.0 0 192.168.1.1
R1配置:
system-view
[Huawei]sysname R1
[R1]acl number 2000

[R1-acl-basic-2000]quit
[R1]interface GigabitEthernet 0/0/1
[R1-GigabitEthernet0/0/1]ip address 12.12.12.1 30
[R1-GigabitEthernet0/0/1]nat outbound 2000
[R1-GigabitEthernet0/0/1]quit
[R1]interface GigabitEthernet 0/0/2
[R1-GigabitEthernet0/0/2]ip address 192.168.1.1 30
[R1-GigabitEthernet0/0/2]quit
[R1]ip route-static 0.0.0.0 0 GigabitEthernet 0/0/1
[R1]ip route-static 172.16.101.0 255.255.255.0 192.168.1.2
结果（看一下连通性）：
先查看PC1能不能ping通交换机和路由
在使用R1路由看看能不能ping通外网

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:
[root@zookeeper1 ~]# tar -zvxf kafka_2.11-1.1.1.tgz
[root@zookeeper1 ~]# cd kafka_2.11-1.1.1/config/
[root@zookeeper1 config]# vim server.properties
把broker.id=0和zookeeper.connect=localhost:2181使用#注释掉可以使用在vim中/加要搜索的名字，来查找，并添加三行新的内容：
#broker.id=0
#zookeeper.connect=localhost:2181
broker.id = 1
zookeeper.connect = 192.168.1.10:2181,192.168.1.20:2181,192.168.1.30:2181
listeners = PLAINTEXT://192.168.1.10:9092

Created topic "test".
# 注释：测试结果：

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）：
