1. 在Amazon Virtual Private Cloud(VPC)中创建一个新的负载均衡器

aws elbv2 create-load-balancer --name YOUR-INTERNAL-LOAD-BALANCER-NAME \
--type network --scheme internal --subnets subnet-XXXXXXXX

2. 创建一个新的目标组(Target Group)

aws elbv2 create-target-group --name YOUR-TARGET-GROUP-NAME \
--protocol TCP --port 80 \
--vpc-id YOUR-VPC-ID \
--health-check-interval-seconds 10 \
--health-check-protocol HTTP --health-check-path /

3. 将需要被负载均衡的实例加入到新的目标组中

aws elbv2 register-targets --target-group-arn YOUR-TARGET-GROUP-ARN \
--targets Id=i-XXX Id=i-YYY ...

4. 创建一个新的负载均衡监听器

aws elbv2 create-listener --load-balancer-arn YOUR-INTERNAL-LOAD-BALANCER-ARN \
--protocol TCP --port 80 \
--default-actions Type=forward,TargetGroupArn=YOUR-TARGET-GROUP-ARN
