how to install service by API or by other auto way

mike_bronson7 — Sun, 18 Aug 2019 06:55:40 GMT

in my Ambari cluster we have some services that not installed yet

as graphite service as described here ( in the picture )

what are the API commands that required in order to identify which service is/are available to install

and the API that install the service

@Michael Bronson,

You can use this API to get all the available services.

http://{ambari-server}:{port}/api/v1/clusters/{clustername}/stack_versions/{stack-version-no}/repository_versions/{repository-version-no}

Hit the above API and parse "RepositoryVersions -> services" array

To check list of installed services you can use

http://{ambari-server}:{port}/api/v1/clusters/{clustername}/services.

Check the diff between two to find out the services which are not installed

To install the service use

curl -u <username>:<password> -i -X PUT -d '{"ServiceInfo": {"state" : "INSTALLED"}}'  http://<ambari-server-host>:{port}/api/v1/clusters/<cluster-name>/services/<service-name>;

Thanks,

Aditya

hi aditye regarding the - http://{ambari-server}:{port}/api/v1/clusters/{clustername}/services. , can you show me please the full approach ( full syntax )

Re: how to install service by API or by other auto way

get list of available services : curl -k -u {username}:{password} -H "X-Requested-By:ambari" -i -X GET http://{ambari-server}:{port}/api/v1/clusters/{clustername}/stack_versions/{stack-version-no}/repository_versions/{repository-version-no}

Get list of installed services: curl -k -u {username}:{password} -H "X-Requested-By:ambari" -i -X GET http://{ambari-server}:{port}/api/v1/clusters/{clustername}/services

To get the {stack-version-no} you can hit below API and see the available stack versions

curl -k -u {username}:{password} -H "X-Requested-By:ambari" -i -X GET http://{ambari-server}:{port}/api/v1/clusters/{clustername}/stack_versions/

Similarly to get {repository-version-no}, get {stack-version-no} from above call and hit below url

curl -k -u {username}:{password} -H "X-Requested-By:ambari" -i -X GET http://{ambari-server}:{port}/api/v1/clusters/{clustername}/stack_versions/{stack-version-no}/

replace the placeholders with your values

hi aditye , can you give me real example for the first API

second how to get these values ?

stack_versions

{stack-version-no}

repository_versions

{repository-version-no}

@Michael Bronson,

To get the {stack-version-no} , hit below API

curl -k -u {username}:{password} -H "X-Requested-By:ambari" -i -X GET http://{ambari-server}:{port}/api/v1/clusters/{clustername}/stack_versions/

ex: curl -k -u admin:admin -H "X-Requested-By:ambari" -i -X GET http://172.31.192.200:8080/api/v1/clusters/cl1/stack_versions

{
  "href" : "http://172.31.192.200:8080/api/v1/clusters/cl1/stack_versions",
  "items" : [
    {
      "href" : "http://172.31.192.200:8080/api/v1/clusters/cl1/stack_versions/1",  --> stack version no
      "ClusterStackVersions" : {
        "cluster_name" : "cl1",
        "id" : 1,
        "repository_version" : 1,
        "stack" : "HDP",
        "version" : "2.6"
      }
    }
  ]
}
<br>

To get {repository-version-no} , hit below API

curl -k -u {username}:{password} -H "X-Requested-By:ambari" -i -X GET http://{ambari-server}:{port}/api/v1/clusters/{clustername}/stack_versions/{stack-version-no}

ex: curl -k -u admin:admin -H "X-Requested-By:ambari" -i -X GET http://172.31.192.200:8080/api/v1/clusters/cl1/stack_versions/1

{
  "href" : "http://x.x.x.x:8080/api/v1/clusters/cl1/stack_versions/1/",
  "ClusterStackVersions" : {
    "cluster_name" : "cl1",
    "id" : 1,
    "repository_version" : 1,
    "stack" : "HDP",
    "state" : "CURRENT",
    "version" : "2.6",
    "host_states" : {
      "CURRENT" : [
        "hbase-migration-repro-4.novalocal",
        "hbase-migration-repro-1.novalocal",
        "hbase-migration-repro-3.novalocal",
        "hbase-migration-repro-2.novalocal"
      ],
      "INIT" : [ ],
      "INSTALLED" : [ ],
      "INSTALLING" : [ ],
      "INSTALL_FAILED" : [ ],
      "NOT_REQUIRED" : [ ],
      "OUT_OF_SYNC" : [ ]
    }
  },
  "repository_versions" : [
    {
      "href" : "http://x.x.x.x:8080/api/v1/clusters/hbasetest/stack_versions/1/repository_versions/51", --- > repository version no
      "RepositoryVersions" : {
        "id" : 51,
        "stack_name" : "HDP",
        "stack_version" : "2.6"
      }
    }
  ]
}
<br>

Then you can hit the final API

curl -k -u {username}:{password} -H "X-Requested-By:ambari" -i -X GET http://{ambari-server}:{port}/api/v1/clusters/{clustername}/stack_versions/{stack-version-no}/repository_versions/{repository-version-no}

hi aditya , everything was great until I intend to install the service

for this example we try to install the service - Knox

I try this:

curl -u xxxx:xxxx -i -X PUT -d '{"ServiceInfo": {"state" : "INSTALLED"}}' http://182.243.5.12 :8080/api/v1/clusters/HDP101/services/Knox

mike_bronson7 — Sun, 18 Aug 2019 06:55:32 GMT

here is how I check the service name

curl -k -u xxxxx:xxxx -H "X-Requested-By:ambari" -i -X GET http://182.243.5.12
:8080/api/v1/clusters/HDP101/stack_versions/1/repository_versions/1 | grep display_name | grep -i knox

@Michael Bronson,

I thought it was only an install. If you want to add a service and install the service, there are series of steps which you need to do.

This doc will help you. Currently I do not have configuration for knox which is required in Step 3.

hi Aditya , just to be clear the status for now is that , from ambari GUI when I go to actions --> add service , then I see the Knox service but it is uncheck in the checkbox ! , so what are the steps from here ? , do we need in this case to do ( add service and install service ? )

Re: how to install service by API or by other auto way

asirna — Sun, 12 Nov 2017 18:07:34 GMT

@Michael Bronson,

Yes. You need to add the service -> install the service and start the service. If you do it from Ambari , it will take care of all these after "Configure services" step
