用于自动启动和停止 AWS EC2 实例的脚本

Question

I've installed Cloudera cluster on 4 nodes Amazon EC2 instance. For certain time such as Monday-Friday Night, Saturday, and Sunday, I didn't need to use those 4 nodes Amazon EC2 instance for more effective cost.

How to automate start and stop an those Amazon EC2 instances using script? Could anybody give me the example of the script to do it?

Thanks,

Answer 1

You can create script to stop and start instance(s) or directly run commands through crontab in linux or schedule-task in windows

for example if you want to stop instance at 11.00 pm
add below line in crontab (you will get this through crontab -e )

0 23 * * * sh stop.sh

format is
mh dom mon dow command

for start instance
aws ec2 start-instances --instance-ids i-1a1234

for stop instance
aws ec2 stop-instances --instance-ids i-1a1234

Answer 2

I have written a small shell script to automate the starting and loggin in to my aws instances via terminal. You can use it

#!/bin/bash
aws ec2 start-instances --instance-ids i-070107834ab273992


public_ip=aws ec2 describe-instances --instance-ids i-070107834ab2 \
        --query 'Reservations[*].Instances[*].PublicDnsName' --output text


AWS_KEY="/home/debian/cs605 data management/assignment6/mumbai instance keys"

ssh -v -i "$AWS_KEY"/mumbai-instance-1.pem\
        ec2-user@$public_ip
