Thanks.

after reading the link, I added discovery.type: single-node. It works like a charm...thank u ...but it comes up another issue for me.

Because I would like to use kibana but received a red, so I followed
curl -s http://localhost:9200/.kibana/_recovery?pretty
curl -XPUT 'localhost:9200/.kibana/_settings' -d '
{
"index" : {
"number_of_replicas" : 0
}
}'

tried to make red to green in kibana.
Unfortunately, the error is {"error":"Content-Type header [application/x-www-form-urlencoded] is not supported","status":406}

so how can this be solved?

You need to pass a Content-Type to tell elasticsearch that you want to communicate in JSon.
