Question

我尝试从AWS Cloudformation模板中的Launch Configuration的User-data运行shell脚本。我用里面的一些脚本创建了AMI。

以下是LaunchConfiguration的Cloudformation模板的示例：

 "ProcessLC": {
        "Type" : "AWS::AutoScaling::LaunchConfiguration",
        "Properties" : {
            "ImageId": {"Ref" : "GeneralAMI"},
            "InstanceType" : "t2.medium",
            "SecurityGroups" : [{"Ref": "SecurityGroup"}],
            "KeyName" : {"Ref": "KeyPair"},
            "UserData": {"Fn::Base64": {"Fn::Join": ["", [
              {"Fn::Join": ["", ["Env=",{"Ref": "Env"}," \n"]]},
              {"Fn::Join": ["", ["DBConn=", {"Ref": "Database"}," \n"]]},
              {"Fn::Join": ["", ["DBEngine=", {"Ref": "Metabase"}," \n"]]},
              "#!/bin/bash\n",
              "cd /project/\n",
              "./stop.sh\n",
              "./vpcAssignIP.sh\n"
              ]
            ]
          }
        } 
      }
    }

当我创建堆栈时，它没有运行（正如我在log＆＃34; /var/log/cloud-init.log"中看到的那样）。我做错了什么？

谢谢！

将此行放在顶部，而不是向下：＆＃34;＃！/斌/庆典\ n＆＃34 ;.该行告诉它将整个脚本作为bash命令处理。它必须是第一线。（所以，在你的加入中，如果你把它放在＆＃34;＆＃34;而不是在加入之后，你应该很好。）

修改有了你的联接，这应该有效：

"UserData": {"Fn::Base64": {"Fn::Join": ["", [ "#!/bin/bash\n", {"Fn::Join": ["", ["Env=",{"Ref": "Env"}," \n"]]}, {"Fn::Join": ["", ["DBConn=", {"Ref": "Database"}," \n"]]}, {"Fn::Join": ["", ["DBEngine=", {"Ref": "Metabase"}," \n"]]}, "cd /project/\n", "./stop.sh\n", "./vpcAssignIP.sh\n" ]

启动配置Userdata shell脚本不从Cloudformation运行
