1. 启动集群   
（1）进入CloudFormation，在aws控制台搜索 CloudFormation，进入CloudFormation主页   
（2）创建堆栈，选在现有模板->上传现有模板，模板下地址：https://chukonu.houdutech.cn/aws-download/cloudformation-chukonu-v1.0.yaml    
（3）设置参数，在指定堆栈详细信息中，InstanceCount 设置为3，InstanceType 选在ec2实例，推荐使用m6i.2xlarge，也可以根据自己实际情况调整   
（4）其他堆栈选项按照默认参数即可，最后提交
 (5) 北京地区和宁夏地区的镜像id不一样,北京地区:ami-0d5569dae64ab95a9,宁夏地区:ami-050748b8d4ee9f1d1,启动CloudFormation时注意替换对应的镜像id,目前默认北京地区    
2. 运行测试程序   
（1）下载测试脚本和程序。   
测试脚本下载地址：https://chukonu.houdutech.cn/aws-download/submit-job.sh   
测试程序下载地址：https://chukonu.houdutech.cn/aws-download/word_count.py   
（2）下载完成后将submit-job.sh、word_count.py 上传到chukonuMaster这台服务器用户目录下，然后再/mnt/data目录下创建word_count.txt,并写入一些文本,然后执行命令 sh submit-job.sh 进行测试   
3. 安全说明
(1)启动集群需要用户有EC2,EFS,CloudFormation,EC2 Auto Scaling,Systems Manager操作权限,具体策略见附录权限策略json
(2)连接服务器进入Systems Manager,Paramter store 可以查看密钥,通过该密钥连接服务器
(3)连接服务器时,安全组需要打开22端口
注意：订阅完成后按照上述操作进行，可以不用在网站或ec2控制台启动服务器
