我有以下代码来创建包含用户数据的EC2实例...
但是在创建EC2实例后它不会创建日志文件。
如果我做错了什么，请帮助我。
代码如下： -
class EC2Demo{
<br>public static void main(String str[]){
{ //AWS Credencial lines......
RunInstancesRequest request = new RunInstancesRequest();
request.setInstanceType(InstanceType.T1Micro);
request.setMinCount(1);
request.setMaxCount(1);
request.setImageId("ami-ab844dc2");
request.setKeyName("VIIT1");
ArrayList<String> securityGroups = new ArrayList<String>();
securityGroups.add("VIITgroup");
request.setSecurityGroups(securityGroups);
Placement placement=new Placement();
placement.setAvailabilityZone("us-east-1d");
request.setPlacement(placement);
request.setUserData(getUserDataScript());
System.out.println("Shell Script");
System.out.println("-------->>>>"+ec2.runInstances(request));
//}
System.out.println("End");
}
private static String getUserDataScript(){
ArrayList<String> lines = new ArrayList<String>();
lines.add("#! /bin/bash");
lines.add("cd /home");
lines.add("echo `ls` >> /home/test.log");
//lines.add("shutdown -h 0");
String str = new String(Base64.encodeBase64(join(lines, "\n").getBytes()));
return str;
}
static String join(Collection<String> s, String delimiter) {
StringBuilder builder = new StringBuilder();
Iterator<String> iter = s.iterator();
while (iter.hasNext()) {
builder.append(iter.next());
if (!iter.hasNext()) {
break;
}
builder.append(delimiter);
}
return builder.toString();
}
}
