如何使用php aws sdk启动和停止ec2实例

$image_id  = 'ami-3d4ff254'; //Ubuntu 12.04
$min       = 1;              //the minimum number of instances to start
$max       = 1;              //the maximum number of instances to start
$options   = array(
    'SecurityGroupId' => 'default',//replace with your security group id
    'InstanceType'    => 't1.micro','KeyName'         => 'keypair',//the name of your keypair for auth
    'InstanceInitiatedShutdownBehavior' => 'terminate' //terminate on shutdown
);

require_once('AWSSDKforPHP/sdk.class.PHP');

$ec2 = new AmazonEC2();

$response = $ec2->run_instances($image_id,$min,$max,$options);

if(!$response->isOK()){
    echo "Start Failed\n";
}

这是假设您正确设置了您的AWS凭据…希望这会让您指向正确的方向……
