以下是从定义的 AMI 启动机器的基本示例:
$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 AWS 凭证......希望这能让您指出正确的方向......

如果您有兴趣,这是一个更详细的脚本:
// Sleep time to allow EC2 instance to start up
$sleeptime = 15;
$username = "ec2-user";
// For AWS PHP SDK
putenv('HOME=/home/ec2-user/');
require_once 'AWSSDKforPHP/sdk.class.php';
// Get data from HTTP POST
$ami = $_POST['amis'];
$instancetype = $_POST['instancetype'];
$keyname = $_POST['key'];
$securitygroup = $_POST['securitygroups'];
// Instantiate the AmazonEC2 class
$ec2 = new AmazonEC2();
// Boot an instance of the image
$response = $ec2->run_instances($ami, 1, 1, array(
'KeyName' => $keyname,
'InstanceType' => $instancetype,
'SecurityGroupId' => $securitygroup,
));
if (!($response->isOK())) {
echo "<p class='error'>ERROR! Could not create new instance!</p>";
return;
}
$instance = $response->body->instancesSet->item->instanceId;
$message = "<p>Your instance has been successfully created.</p>";
$message .= ("<p>Instance ID is: <b>$instance</b></p>");
// Give instance some time to start up
sleep ($sleeptime);
// Get the hostname from a call to the DescribeImages operation.
$response = $ec2->describe_instances(array(
'Filter' => array(
array('Name' => 'instance-id', 'Value' => "$instance"),
)
));
if (!($response->isOK())) {
echo "<p class='error'>ERROR! Could not retrieve hostname for instance!</p>";
return;
}
$hostname = $response->body->reservationSet->item->instancesSet->item->dnsName;
// Output the message
$message .= "<p>Your instance hostname is: <b>$hostname</b></p>";
$message .= "<p>You can connect to your instance using this command:<br>" .
"<b>ssh -i $keyname.pem $username@" . $hostname . "</b></p>";
echo $message;
与@dleiftah 的几乎相同,只是它在完成时输出新实例的主机名。
