graylog2 - ERROR : Could not successfully connect to ElasticSearch. 检查您的集群状态是否不是 RED 并且 ElasticSearch 运行正常

我已经提到了Setup a graylog2 server with elasticsearch in a vagrant machine，并且拥有正确版本的ElasticSearch。

我还根据 tutorial 为 Graylog2 和 ElasticSearch 添加了正确的选项。

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

Terminating. :(

我运行时仍然收到该错误:

sudo java -jar /opt/graylog2-server/graylog2-server.jar --debug

我还检查了 ElasticSearch 是否正常运行 -

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
}

关于我应该做什么的任何建议？我不明白问题是什么。

最佳答案

我通过以下添加来运行设置 -

# /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
