我在我创build的VPC内部启动Elastic Beanstalk应用程序时出现问题。
我的VPC如下所示：
id: vpc-a1b name: vpc-green cidr: 10.0.0.0/16 route table: rtb-1ab acl: acl-123 然后我有6个子网：
vpc-green-public-us-east-2a (rt: vpc-green-rt-public) vpc-green-public-us-east-2b (rt: vpc-green-rt-public) vpc-green-public-us-east-2c (rt: vpc-green-rt-public) vpc-green-private-us-east-2a (each has its own rt) vpc-green-private-us-east-2b vpc-green-private-us-east-2c
路线表：
vpc-green-rt-public 10.0.0.0/16 local 0.0.0.0/0 igw-123 vpc-green-rt-private-us-east-2a 10.0.0.0/16 local 0.0.0.0/0 nat-001
互联网网关：
vpc-green-igw
ACL：
vpc-green-acl inbound: 100 ALL/All/All 0.0.0.0/0 ALLOW * All/All/All 0.0.0.0/0 DENY outbound: 100 ALL/All/All 0.0.0.0/0 ALLOW * All/All/All 0.0.0.0/0 DENY associated subnets: all 6 (public and private)

ElasticBeanstalk创build的实际ec2实例如下所示：
t2.small security groups: vpc-green-web EB-VPC-Security subnet: one of my public subnets (vpc-green-public-us-east-2a)
EB创build的负载均衡器如下所示：
security groups: EB-load-balancer subnet: one of my public subnets (vpc-green-public-us-east-2a)
我收到一个错误 ：
The EC2 instances failed to communicate with AWS Elastic Beanstalk, either because of configuration problems with the VPC or a failed EC2 instance. Check your VPC configuration and try launching the environment again. Stack named 'awseb-e-xxxxx-stack' aborted operation. Current state: 'CREATE_FAILED' Reason: The following resource(s) failed to create: [AWSEBInstanceLaunchWaitCondition].
这里有一个帮助页面： http : //docs.aws.amazon.com/elasticbeanstalk/latest/dg/events.common.connectivity.html
它表示：“ 这意味着Amazon EC2实例未与Elastic Beanstalk通信，因此它们已成功启动。 ”
鉴于以上信息，究竟是什么问题？
我不知道如何解决这个问题，因为它对我来说很好。
如果我访问EB生成的url不起作用：
xxxxx.us-east-2.elasticbeanstalk.com is currently unable to handle this request.
所以问题最终是我的DNS主机名和我的VPC设置支持没有设置为True。
Aws支持今天的人们！
