安装完Elastic Search后,默认情况下,服务只能在本地访问(127.0.0.1)

如果希望在其他机器上访问Elastic Search,则需要修改配置文件,默认位置在:/etc/elasticsearch/elasticsearch.yml

[root@elasticsearch elasticsearch]# pwd
/etc/elasticsearch
[root@elasticsearch elasticsearch]# 
[root@elasticsearch elasticsearch]# ls -ltr

# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
#       Before you set out to tweak and tune the configuration, make sure you
#       understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
#cluster.name: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
#node.name: node-1
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
path.data: /var/lib/elasticsearch
#
# Path to log files:
#
path.logs: /var/log/elasticsearch
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
#bootstrap.memory_lock: true
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
#network.host: 192.168.0.1
network.host: 192.168.40.251
#
# Set a custom port for HTTP:
#
#http.port: 9200
http.port: 9200
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#discovery.seed_hosts: ["127.0.0.1", "192.168.40.251"]
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#
#cluster.initial_master_nodes: ["node-1", "node-2"]
#
# For more information, consult the discovery and cluster formation module documentation.
#
# ---------------------------------- Gateway -----------------------------------
#
# Block initial recovery after a full cluster restart until N nodes are started:
#
#gateway.recover_after_nodes: 3
#
# For more information, consult the gateway module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Require explicit names when deleting indices:
#
#action.destructive_requires_name: true
[root@elasticsearch elasticsearch]# 

注意,其中的:

  1. network.host
  2. http.port

然后,重启服务就会遇到如题所示的错误:

其实,关于这个问题,查看Elastic Search的后端日志就可以很明白,默认位置:/var/log/elasticsearch/elasticsearch.log

(过多的输出,...)

请注意上面的【[ERROR]】部分:

[2019-08-12T00:32:00,886][ERROR][o.e.b.Bootstrap          ] [elasticsearch.adamhuan.com] node validation exception
[1] bootstrap checks failed
[1]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured

错误原因:
在为ElasticSearch配置公共IP的时候,需要设置以下几个参数:

  1. network.host
  2. http.port
  3. discovery.seed_hosts

如果没有配置【discovery.seed_hosts】,则会遇到上面的错误。

修改后的ElasticSearch配置文件:

[root@elasticsearch elasticsearch]# pwd

[root@elasticsearch elasticsearch]# ls -ltr

[root@elasticsearch elasticsearch]# 

然后,启动ElasticSearch服务:

[root@elasticsearch elasticsearch]# service elasticsearch restart
