/home/ubuntu/Play20/play  run

/etc/rc.local


#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

/home/ubuntu/startplay.sh

set configuration

$ export AWS_CREDENTIAL_FILE=/home/jiansen/AWS/aws-credentials.txt

$ as-create-launch-config AutoScaleLC --image-id ami-a9f8e6dd --region eu-west-1 --instance-type t1.micro --group awseb-e-ictxp7cjjz-stack-AWSEBSecurityGroup-YAXYRWU3MQO8 --key autokey OK-Created launch config

After use, set zero instances in the Auto Scaling Group?

$as-update-auto-scaling-group auto-scaling-X-X --desired-capacity 0 --max-size 0 --min-size 0 --region eu-west-1

Update Auto-Scaling Group status

$ as-update-auto-scaling-group MyGroup --launch-configuration MyLC --availability-zones us-west-2a --min-size 1 --max-size 12 OK-Updated AutoScalingGroup

Set Load Balancer

AWS Console

check for

  • DNS Name: e.g. MyLoadBalancer-360063211.eu-west-1.elb.amazonaws.com
  • Port Configuration
