AWSCloudFormation - cfn-init無法運行命令

Question

我正在使用cloudformation安裝elasticsearch。 我正在下載並解壓縮tar.gz. 以下是我的EC2實例部分：

"masterinstance": { 
     "Type": "AWS: : EC2: : Instance", 
     "Metadata": { 
      "AWS: : CloudFormation: : Init": { 

        "configSets" : { 
        "ascending" : [ "config1" , "config2" ] 

        }, 
       "config1": { 
        "sources": { 
         "/home/ubuntu/": "https: //s3.amazonaws.com/xxxxxxxx/elasticsearch.tar.gz" 
        }, 
        "files": { 
         "/home/ubuntu/elasticsearch/config/elasticsearch.yml": { 
          "content": { 
           "Fn: : Join": [ 
            "", 
            [ 
             xxxxxxxx 
            ] 
           ] 
          } 
         } 
        } 

       }, 

        "config2" : { 
         "commands": { 
         "runservice": { 
         "command": "~/elasticsearch/bin/elasticsearch", 
         "cwd" : "~", 
         "test" : "~/elasticsearch/bin/elasticsearch > test.txt", 
         "ignoreErrors" : "false" 
         } 
        } 
       } 
      } 
     }, 
     "Properties": { 
      "ImageId": "ami-xxxxxxxxxx", 
      "InstanceType": { 
       "Ref": "InstanceTypeParameter" 
      }, 
      "Tags": [ 
       xxxxxxxx 
      ], 
      "KeyName": "everybody", 
      "NetworkInterfaces": [ 
       { 
        "GroupSet": [ 
         { 
          "Ref": "newSecurity" 
         } 
        ], 
        "AssociatePublicIpAddress": "true", 
        "DeviceIndex": "0", 
        "SubnetId": { 
         "Ref": "oneSubnet" 
        } 
       } 
      ], 
      "UserData": { 
       "Fn: : Base64": { 
        "Fn: : Join": [ 
         "", 
         [ 
          "#!/bin/bash\n", 

          "sudo add-apt-repository-yppa: webupd8team/java\n", 
          "sudo apt-get update\n", 
          "echo'oracle-java8-installershared/accepted-oracle-license-v1-1selecttrue'|sudo debconf-set-selections\n", 
          "sudo apt-getinstall-yoracle-java8-installer\n", 

          "apt-get update\n", 
          "apt-get-y installpython-setuptools\n", 
          "easy_installhttps: //s3.amazonaws.com/cloudformation-examples/aws-cfn-bootstrap-latest.tar.gz\n", 
          "/usr/local/bin/cfn-init", 
          "--stack Elasticsearch", 
          "--resource masterinstance", 
          "--configsets ascending", 
          "-v\n" 

         ] 
        ] 
       } 
      } 

}}

我使用AWS::CloudFormation::Init配置和其他設置。 提取焦油後，我想開始彈性搜索，我通過AWS::CloudFormation::Init中的command部分進行彈性搜索，但在完成堆棧創建之後， 執行彈出搜索時，我無法看到我的elasticsearch服務正在運行。 所有其他的東西，如提取焦油和創建文件工作正常。

我已經通過CFN-init.log走了，它給我的以下信息：

2016-07-19 05:53:15,776 P2745 [INFO] Test for Command runservice 
2016-07-19 05:53:15,778 P2745 [INFO] -----------------------Command Output----------------------- 
2016-07-19 05:53:15,778 P2745 [INFO] /bin/sh: 1: ~/elasticsearch/bin/elasticsearch: not found 
2016-07-19 05:53:15,778 P2745 [INFO] ------------------------------------------------------------ 
2016-07-19 05:53:15,779 P2745 [ERROR] Exited with error code 127 
~ 

如果我火了上面的命令~/elasticsearch/bin/elasticsearch直接在我的實例則可以正常使用。

我在做什麼錯在這裏。

謝謝。

我猜測主目錄（〜）在嘗試運行ES時正在對不同的用戶（而不是Ubuntu）進行評估。我認爲CFN-Init作爲root用戶運行，而不是作爲ubuntu/ec2用戶運行。嘗試將config2命令塊中的路徑更改爲完全限定的路徑（/ home/ubuntu/elasticsearch）。
