我的EC2启动脚本（在user_data中提供）似乎在启动时不运行

标签： amazon-ec2 boto autoscaling

我正在使用boto将aut2实例作为自动缩放组的一部分启动。我读了一个简单的bash脚本并将base64编码的字符串传递给user_data。我正在使用Ubuntu AMI（ami-a73264ce），但我还尝试了另一个Ubuntu AMI（ami-ad184ac4）和Amazon Linux AMI（ami-bba18dd2），因为一个stackoverflow答案表明AMI可能是问题所在（{ {3}}）

这是我的脚本（startup.sh）

    #!/bin/bash
    mkdir newdir

这是我的boto代码：

  conn = AutoScaleConnection(aws_access_key_id=AWS_ACCESS_KEY_ID, aws_secret_access_key=AWS_SECRET_ACCESS_KEY)

  f = open('startup.sh', 'r')
  user_data = f.read()
  lc = LaunchConfiguration(name=launch_config_name, image_id=ami_id,
                           key_name=key_name, security_groups=security_groups,
                           user_data=base64.b64encode(user_data))
  conn.create_launch_configuration(lc)

  ag = AutoScalingGroup(group_name=group_name, load_balancers=load_balancers,
                        availability_zones=availability_zones, launch_config=lc,
                        min_size=min_size, max_size=max_size, connection=conn)

  conn.create_auto_scaling_group(ag)

这是我的/ var / log / syslog：

当我使用命令行工具时它可以工作，但我仍然想知道为什么它不适用于boto因为使用boto可能更方便

检查您的用户数据是否在您的实例中填充：

 /var/lib/cloud/data/scripts

每个声明都有换行符吗？

如何将此内容添加到脚本中以检查用户数据是否正确？

f = open('startup.sh', 'r')
user_data = f.read()
print user_data

答案 1 :(得分：0)

原来它在python中不一定是base64，这对我有用：

#cat make-a-dir.sh
#!/bin/bash
mkdir newdir

然后是我的python：

shell_script = 'make-a-dir.sh'
with open (shell_script, "r") as myfile:
  data=myfile.read()

然后我将其传递给：

run_instances(ami_id,security_group_ids=["sg-1111111"],key_name="my-key",instance_type=instance_type,placement=az,subnet_id=subnet_id,dry_run=dry_run,user_data=data)

做了一个款待。祝你好运！
