Graylog2 伺服器無法連接到 Elasticsearch
除了使用最新版本的組件外,我嘗試遵循Digital Ocean 手冊。我的
elasticsearch.yml
:cluster.name: graylog2 network.bind_host: localhost network.publish_host: localhost script.disable_dynamic: true
Elasticsearch 說沒問題。然後我嘗試了三個版本
graylog2.conf
:is_master = true node_id_file = /etc/graylog2-server-node-id password_secret = YRdFrLaoQQfRuSccOhU7Vy8vfoWlobVK5ZXf9G6joag4KyPQMLiITfO6EMysO2VrAwunhqE2e7gAVhuN4izPK0jakrtQqnRg root_password_sha2 = 5e884898da28047151d0e56f8dc6292773603d0d6aabbdd62a11ef721d1542d8 plugin_dir = plugin rest_listen_uri = http://127.0.0.1:12900/ rest_transport_uri = http://127.0.0.1:12900/ elasticsearch_max_docs_per_index = 20000000 elasticsearch_max_number_of_indices = 20 retention_strategy = delete elasticsearch_shards = 1 elasticsearch_replicas = 0 elasticsearch_index_prefix = graylog2 allow_leading_wildcard_searches = false allow_highlighting = false elasticsearch_analyzer = standard output_batch_size = 25 output_flush_interval = 1 processbuffer_processors = 5 outputbuffer_processors = 3 processor_wait_strategy = blocking ring_size = 1024 dead_letters_enabled = false lb_recognition_period_seconds = 3 mongodb_useauth = false mongodb_host = 127.0.0.1 mongodb_database = graylog2 mongodb_port = 27017 mongodb_max_connections = 100 mongodb_threads_allowed_to_block_multiplier = 5 transport_email_enabled = false transport_email_hostname = mail.example.com transport_email_port = 587 transport_email_use_auth = true transport_email_use_tls = true transport_email_use_ssl = true transport_email_auth_username = you@example.com transport_email_auth_password = secret transport_email_subject_prefix = [graylog2] transport_email_from_email = graylog2@example.com
在第二個版本中,我添加了一行
elasticsearch_discovery_zen_ping_unicast_hosts = 127.0.0.1:9200
,在第三個版本中添加了與9300
埠相同的行。有了這些配置,我有 3 個日誌
sudo java -jar /opt/graylog2-server/graylog2-server.jar --debug
:第一、第二和第三。他們都失敗了。是組件的某些版本不兼容嗎?或者有沒有辦法在我的環境中解決這個問題?
您必須使用版本 0.90.10 的 Elasticsearch 和 Graylog2 0.20。它使用的是二進制協議,不幸的是,這些協議在版本之間通常不兼容。
這一行:
org.elasticsearch.transport.RemoteTransportException: Failed to deserialize exception response from stream
是什麼讓問題消失了,協議不同,所以 Elasticsearch 客戶端無法連接到伺服器。如果您使用 0.90.10,它將起作用。
