Guys, I had an old install and it was not working. I got a "Connection refused" when trying `$ curl -X GET http://localhost:9200` So, I purged my install and installed it again (now with 2.x). After that, I must got the same message, no matter if I stop and start the service. So, after using `service elasticsearch start` and then ```auto sudo -u elasticsearch /usr/share/elasticsearch/bin/elasticsearch -d -p /var/run/elasticsearch.pid --default.config=/etc/elasticsearch/elasticsearch.yml --default.path.home=/usr/share/elasticsearch --default.path.logs=/var/log/elasticsearch --default.path.data=/var/lib/elasticsearch --default.path.work=/tmp/elasticsearch --default.path.conf=/etc/elasticsearch ``` it worked, what I'm missing here? Seems that the Ubuntu services can't start it. I also configured `elasticsearch.yml` with `network.host: localhost` and `http.port: 9200`. Thanks. ---

> [@taq](#): > > network.host: localhost There were some changes in 2.X, see [Networking | Elasticsearch Guide [8.11] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html) But that should work. Can you start ES directly? ---

Hey, thanks for answering. I noticed some of the changes, that's why I tried to change `elasticsearch.yml`, but didn't noticed that now `localhost` should be `_local_`, thanks! So, first I tried to start it with the current configuration and tried to accesss with `curl` ... and it worked!: ```auto $ sudo service elasticsearch start $ sudo service elasticsearch status ● elasticsearch.service - Elasticsearch Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; disabled; vendor preset: enabled) Active: active (running) $ curl -X GET http://localhost:9200 { "name" : "Atalon", "cluster_name" : "elasticsearch", "version" : { "number" : "2.1.0", "build_hash" : "72cd1f1a3eee09505e036106146dc1949dc5dc87", "build_timestamp" : "2015-11-18T22:40:03Z", "build_snapshot" : false, "lucene_version" : "5.3.1" }, "tagline" : "You Know, for Search" } ``` Yesterday no matter what I did it won't start without the longer command line. But now I'm a different network (wireless now, cable yesterday), can have something related to it? But, after changing `localhost` to `_local_`, I got the connection refused again. ☹ Checking with `netstat`, I got some interesting results: ```auto tcp6 0 0 ::1:9200 :::* OUÇA - tcp6 0 0 127.0.0.1:9200 :::* OUÇA - tcp6 0 0 ::1:9300 :::* OUÇA - ``` So, I tried to use IPV6 and ... ```auto $ curl -X GET http://[::1]:9200 { "name" : "Coldblood", "cluster_name" : "elasticsearch", "version" : { "number" : "2.1.0", "build_hash" : "72cd1f1a3eee09505e036106146dc1949dc5dc87", "build_timestamp" : "2015-11-18T22:40:03Z", "build_snapshot" : false, "lucene_version" : "5.3.1" }, "tagline" : "You Know, for Search" } ``` And after this, IPV4 worked again! Checking with `netstat` again, I got an interesing result on remote address (btw, "ouça" is "listen"): ```auto tcp 0 0 127.0.0.1:58958 127.0.0.1:9200 TIME_WAIT - tcp6 0 0 ::1:9200 :::* OUÇA - tcp6 0 0 127.0.0.1:9200 :::* OUÇA - tcp6 0 0 ::1:9300 :::* OUÇA - tcp6 0 0 127.0.0.1:9300 :::* OUÇA - ``` I tried `curl -X GET http://localhost:58958` too but got connection refused, but `localhost` and `127.0.0.1` works. Then I changed `network.host` to `_local:ipv4_` and checked again. On `netstat`, just IPV6: ```auto tcp6 0 0 127.0.0.1:9200 :::* OUÇA - tcp6 0 0 127.0.0.1:9300 :::* OUÇA - ``` But after the first `curl` request, seems that the remote address is bound, and it worked again! ```auto tcp 0 0 127.0.0.1:59230 127.0.0.1:9200 TIME_WAIT - tcp6 0 0 127.0.0.1:9200 :::* OUÇA - tcp6 0 0 127.0.0.1:9300 :::* OUÇA - ``` Not really sure what is happening. 🙂 ---
