任务一:基础设施建设。(分值:145分)
1、 创建三个VPC(名称自定义),并且将Database01和云计算redis分别更改到不同VPC下。【10分】
2、按照2核CPU、4G内存、40G硬盘创建四台分别名为node1、node2、Database01和redis的云主机。【10分】

其它参数
默认
2、 配置对等路由将Database01、redis和node1、node2所处的网络打通并保证四台主机之间网络可用。【25分】
互相建立对等连接即可不同网段互联
参考:《HCIA-Cloud Service V2.2 实验手册》
3.网络类服务实践
方案一:
3.3.5 创建对等连接,使同区域不同 VPC 内的 ECS 进行通信 117页
同网段内的IP地址可以互ping
不能互ping
解决方法:
1. 进入网络控制台找到《对等链接》
方案二:
当bj四区域弹性IP配额不足时,可在其他区域购买弹性IP用VPN专线连接使其可以互相通信:
步骤:
北京四区
北京一区:
如果改完之后状态栏显示“未连接”
解决办法:
刷新一下,状态栏就会变正常
3、 创建一个10G的云硬盘,并将其挂载到Database01的云主机上,并将其进行格式成ext4的格式。【20分】

7、创建一个负载均衡器,将node1和node2加入负载均衡的后端。设置一个可用的服务IP,服务端口为80,并绑定一个可用的弹性公网IP,对弹性公网IP进行Web访问测试。【40分】

这里异常可能是安全组没有开放80端口,开放之后再去刷新一下
任务二:业务部署和迁移。(分值655分)
1、 使用node1,node2安装部署apache,PHP服务,并确保能对外提供业务。【50分】
(注意弹性公网IP配额)
[root@ecs-node-0001 ~]# yum -y install httpd php php-fpm php-server php-mysql
Loaded plugins: fastestmirror

[root@ecs-node-0001 ~]# systemctl restart httpd

[root@ecs-node-0002 ~]# systemctl enable php-fpm
Created symlink from /etc/systemd/system/multi-user.target.wants/php-fpm.service to /usr/lib/systemd/system/php-fpm.service.
两个公网IP区web界面查看能否访问http
如果不能就去安全组添加tcp:80端口
2、 在Database01云主机上部署MySQL服务,并且保证node1、node2能够访问mysql服务,并且使用SQL语句创建后续需要使用得数据库(数据库名自定义)。【100分】
在这一步之前千万不要直接安装MySQL,不然会找不到密码
[root@database1 ]# wget http://dev.mysql.com /get/mysql57-community-release-el7-8.noarch.rpm
[root@database1 ~]# ll

3、 使用现有软件包在node1、node2安装Discuz网站。【100分】
Node1 node2同等操作
wget http://download.comsenz.com/DiscuzX/3.2/Discuz_X3.2_SC_UTF8.zip
ll
unzip Discuz_X3.2_SC_UTF8.zip
ll
cp -rf upload/* /var/www/html/
chmod 777 /var/www/html/
chmod -R 777 /var/www/html
systemctl restart httpd
systemctl enable httpd
访问网站
4、在云主机redis上部署docker容器服务,在容器当中部署redis服务,并且配置node-1、node-2能够访问redis服务。《redis远程访问》(在网站配置文件【config/config_global.php】当中进行配置redis连接,部署docker采用shell脚本的方式部署,如果不是,则部署docker项不得分)【250分】
安装docker脚本:
[root@shiyan ~]# cat docker.sh
#!/bin/bash
yum update -y
yum-config-manager \--add-repo \https://download.docker.com/linux/centos/docker-ce.repo
sed -i 's+download.docker.com+mirrors.aliyun.com/docker-ce+'/etc/yum.repos.d/docker-ce.repo
yum install -y yum-utils device-mapper-persistent-data lvm2
yum list docker-ce --showduplicates | sort -r
yum install docker-ce -y
systemctl start docker
systemctl enable docker
Docker里面部署redis脚本: (没问题的)也可命令配置
[root@shiyan ~]# cat redis.sh
#!/bin/bash
docker search redis
docker pull redis
docker images
mkdir /usr/local/docker
cd /usr/local/docker
yum -y install wget
wget http://download.redis.io/redis-stable/redis.conf
sed -i 's/bind127.0.0.1/#bind127.0.0.1/g' /usr/local/docker/redis.conf
sed -i 's/protected-mode yes/protected-mode no/g' /usr/local/docker/redis.conf
docker run -itd --name redis-test -p 6379:6379 redis
docker run -itd -p 192.168.100.10:6379:6379 --name redis -v /usr/local/docker/redis.conf:/etc/redis/redis.conf -v /usr/local/docker/data:/data redis redis-server /etc/redis/redis.conf
docker start redis
docker ps -a
docker exec -it redis-test bash
Node1 node2主机同操作
命令:
yum -y install redis
vim /etc/redis.conf
systemctl restart redis
systemctl enable redis
Database1:
root@e8b956d37721:/data# redis-cli -h 192.168.73.182 -p 6379

4、 将node1、node2配置负载均衡服务并验证负载均衡和弹性伸缩服务。【85分】
负载均衡服务:
弹性伸缩服务:
弹性 伸缩组
访问伸缩IP
Ok
5、 云监控服务界面,也可以查看主机监控、云服务监控信息,需要注意的是在进行主机监控时需提前安装插件,要求在云服务监控当中设置磁盘读带宽监控指标。【50分】
6、 在安全组上配置阻止445端口的流量。【20分】
