4.Raid存储管理(40分)

使用提供的虚拟机，该虚拟机存在一块大小为20G的磁盘/dev/vdb，使用fdisk命令对该硬盘进形分区，要求分出三个大小为5G的分区。使用这三个分区，创建名为/dev/md5、raid级别为5的磁盘阵列。创建完成后使用xfs文件系统进形格式化，并挂载到/mnt目录下。将mdadm -D /dev/md5命令和返回结果；df -h命令和返回结果以文本形式提交到答题框。

• 因为我用的是CentOS7系统做的实验所以磁盘是sdb，CentOS6磁盘是vdb：

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.应用商城系统(40分)

使用提供的软件包和提供的虚拟机，完成单节点应用系统部署。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。

这是gpmall上传的开源项目，如果想了解的更加深入的可以访问这个地址 https://gitee.com/mic112/gpmall

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

[root@zookeeper1 config]# cd /root/kafka_2.11-1.1.1/bin/
[root@zookeeper1 bin]# ./kafka-server-start.sh -daemon ../config/server.properties 
[root@zookeeper1 bin]# jps

# 注释：创建topic（下面的IP请设置为自己节点的IP）：
[root@zookeeper1 bin]# ./kafka-topics.sh --create --zookeeper 192.168.1.10:2181 --replication-factor 1 --partitions 1 --topic test
Created topic "test".
# 注释：测试结果：
[root@zookeeper1 bin]# ./kafka-topics.sh --list --zookeeper 192.168.1.10:2181

14.部署Swarm集群(40分)

使用提供的虚拟机和软件包，安装好docker-ce。部署Swarm集群，并安装Portainer图形化管理工具，部署完成后，使用浏览器登录ip:9000界面，进入Swarm控制台。将curl swarm ip:9000返回的结果以文本形式提交到答题框。

Swarm initialized: current node (vclsb89nhs306kei93iv3rwa5) is now a manager.

To add a worker to this swarm, run the following command:

    docker swarm join --token SWMTKN-1-6d9c93ecv0e1ux4u8z5wj4ybhbkt2iadlnh74omjipyr3dwk4u-euf7iax6ubmta5qbcrbg4t3j4 192.168.1.111:2377

To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.

15.Shell脚本补全(40分)

下面有一段脚本，作用是自动配置redis服务，由于工程师的失误，将脚本中的某些代码删除了，但注释还在，请根据注释，填写代码。最后将填写的代码按照顺序以文本形式提交至答题框。 redis(){ cd #修改redis的配置文件，将bind 127.0.0.1注释 sed -i （此处填写） /etc/redis.conf #修改redis的配置文件，将protected-mode yes改为protected-mode no sed -i （此处填写） /etc/redis.conf #启动redis服务 systemctl start redis #设置开机自启 systemctl enable redis if [ $? -eq 0 ] then sleep 3 echo -e "\033[36m==========redis启动成功==========\033[0m" else echo -e "\033[31mredis启动失败，请检查\033[0m" exit 1 fi sleep 2 }

sed -i 's/bind 127.0.0.1/#bind 127.0.0.1/g' /etc/redis.conf
sed -i 's/protected-mode yes/protected-mode no/g' /etc/redis.conf
