I've referred to Setup a graylog2 server with elasticsearch in a vagrant machine and I have the correct version of ElasticSearch.
I've also added the right options for Graylog2 and ElasticSearch as per the tutorial.
ERROR: Could not successfully connect to ElasticSearch. Check that your cluster state is not RED and that ElasticSearch is running properly.

Terminating. :(
I'm still getting that error when I run:
sudo java -jar /opt/graylog2-server/graylog2-server.jar --debug
I've also checked that ElasticSearch is running properly -
central@central:~$ curl -XGET 'http://127.0.0.1:9200/_cluster/health?pretty=true'
{
"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
}
Any suggestions on what I should do? I'm not understanding what the problem is.
I got the setup to run with the following additions -
# /etc/elasticsearch/elasticsearch.yml
cluster.name: graylog2
node.master: true
node.data: true
bootstrap.mlockall: true
ES_HEAP_SIZE: 8192 (@ 16GB memory)
discovery.zen.ping.multicast.enabled: false
discovery.zen.ping.unicasts.hosts: [“127.0.0.1”, "SERVER IP"]
# /etc/graylog2.conf
elasticsearch_discovery_zen_ping_multicast_enabled = false
elasticsearch_discovery_zen_ping_unicast_hosts = IP_ARR:9300
