将Graylog服务器连接到Elastic Search时出现问题

Question

Hi my configurations are:

elasticsearch.yml :

cluster.name: graylog2
node.master: true
node.data: true
bootstrap.mlockall: true
ES_HEAP_SIZE: 8192 (@ 16GB memory)
network.bind_host: 127.0.0.1
script.disable_dynamic: true

graylog2.conf :

is_master = true
node_id_file = /etc/graylog2-server-node-id
password_secret=something
root_password_sha2=something
plugin_dir = plugin
rest_listen_uri = http://127.0.0.1:12900/
rest_transport_uri = http://127.0.0.1:12900/
elasticsearch_shards = 1
elasticsearch_index_prefix = graylog2
elasticsearch_cluster_name = graylog2
elasticsearch_discovery_zen_ping_multicast_enabled = false
elasticsearch_discovery_zen_ping_unicast_hosts = 127.0.0.1:9300

I am trying to install in my apache localhost.

When I check using curl -XGET ' http://localhost:9200/_cluster/health?pretty=true '

The output I get is :

 {
  "cluster_name" : "graylog2",
  "status" : "green",
  "timed_out" : false,
  "number_of_nodes" : 1,
  "number_of_data_nodes" : 1,
  "active_primary_shards" : 0,
  "active_shards" : 0,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 0
}

I have followed the tutorial https://www.digitalocean.com/community/tutorials/how-to-install-graylog2-and-centralize-logs-on-ubuntu-14-04

ERROR: Could not successfully connect to ElasticSearch. Check that your cluster state is not RED and that ElasticSearch is running properly.

with official documentation I haven't problem

• http://docs.graylog.org/en/1.3/pages/installation.html
• http://docs.graylog.org/en/2.0/pages/installation.htm
