实操题(600分):

 

1.交换机管理(40分)

在eNSP中使用S5700交换机进行配置,通过一条命令划分vlan 2、vlan 3、vlan 1004,通过端口组的方式配置端口1-5为access模式,并添加至vlan2中。配置端口10为trunk模式,并放行vlan3。创建三层vlan 2,配置IP地址为:172.16.2.1/24,创建三层vlan1004,配置IP地址为:192.168.4.2/30。通过命令添加默认路由,下一跳为192.168.4.1。(使用完整命令)将上述操作命令及返回结果以文本形式提交到答题框。

SW1配置:

<Huawei>system-view
[Huawei]sysname SW1
[SW1]vlan batch 2 3 1004
[SW1]port-group 1
[SW1-port-group-1]group-member GigabitEthernet 0/0/1 to GigabitEthernet 0/0/5
[SW1-port-group-1]port link-type access
[SW1-port-group-1]port default vlan 2
[SW1]interface GigabitEthernet 0/0/10
[SW1-GigabitEthernet0/0/10]port link-type trunk
[SW1-GigabitEthernet0/0/10]port trunk allow-pass vlan 3
[SW1-GigabitEthernet0/0/10]quit
[SW1]interface Vlanif 2
[SW1-Vlanif2]ip address 172.16.2.1 24
[SW1-Vlanif2]quit
[SW1]interface Vlanif 1004
[SW1-Vlanif1004]ip address 192.168.4.2 30
[SW1-Vlanif1004]quit
[SW1]ip route-static 0.0.0.0 0 192.168.4.1

 

2.交换机管理(40分)

交换机配置:交换机g0/0/1端口连接R1路由器,所属vlan1001,配置地址192.168.1.2/30,与路由器通信。配置g0/0/2连接PC1机,所属vlan101,配置PC1机网关地址为172.16.101.254/24。配置默认路由下一跳为路由器地址。路由器配置:R1路由器g0/0/1端口配置地址12.12.12.1/30,配置端口多路复用PAT配置。R1路由器g0/0/2端口配置地址192.168.1.1/30,连接交换机。路由器配置默认路由访问外部网络,配置静态路由访问PC机网络。(所有配置命令使用完整命令)将上述操作命令及返回结果以文本形式提交到答题框。

 

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]rule 1 permit
[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

4.Raid存储管理(40分)

登录云主机,在云主机中,存在一个大小为20G的硬盘为/dev/vdb,使用fdisk命令对该硬盘进形分区,要求分出两个大小为5G的分区。使用这两个分区,创建名为/dev/md0、raid级别为1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/md0命令和df -h命令返回得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:

# 注释:这个其实配不配都可以,看个人喜欢用主机名还是IP地址咯
[root@mycat ~]# vim /etc/hosts

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

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

[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

[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
test

 

Zookeeper2:

[root@zookeeper2 ~]# tar -zvxf kafka_2.11-1.1.1.tgz
[root@zookeeper2 ~]# cd kafka_2.11-1.1.1/config/
[root@zookeeper2 config]# vim server.properties

broker.id = 2
zookeeper.connect = 192.168.1.10:2181,192.168.1.20:2181,192.168.1.30:2181
listeners = PLAINTEXT://192.168.1.20:9092

[root@zookeeper3 ~]# cd kafka_2.11-1.1.1/config/
[root@zookeeper3 config]# vim server.properties

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。

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

  • 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):

13.Docker安装(40分)

使用提供的虚拟机和软件包,自行配置YUM源,安装docker-ce服务。安装完毕后执行docker info命令的返回结果以文本形式提交到答题框。

  • 先上传Docker.tar.gz到/root目录,并解压:

14.Docker Harbor安装(40分)

15.Shell脚本补全(40分)

下面有一段脚本,作用是自动配置nginx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。 nginx(){ cd #删除默认项目路径下的文件 rm -rf /usr/share/nginx/html/* #将提供的dist静态文件复制到nginx项目目录 cp -rvf /root/dist/* /usr/share/nginx/html #修改nginx配置文件如下 cat > /etc/nginx/conf.d/default.conf << EOF server { listen 80; server_name localhost; #charset koi8-r; #access_log /var/log/nginx/host.access.log main; location / { root /usr/share/nginx/html; index index.html index.htm; } location /user { (此处需要填写) } location /shopping { proxy_pass http://127.0.0.1:8081; } location /cashier { proxy_pass http://127.0.0.1:8083; } error_page 500 502 503 504 /50x.html; location = /50x.html { root /usr/share/nginx/html; } } EOF #启动nginx服务 systemctl start nginx #设置nginx开机自启 (此处需填写) #检查nginx服务是否成功启动 if [ $? -eq 0 ] then sleep 3 echo -e "\033[36m==========nginx启动成功==========\033[0m" else echo -e "\033[31mnginx启动失败,请检查\033[0m" exit 1 fi sleep 2 }
