Question

使用apt-get elasticsearch（版本5.0.0-alpha4）并使用Oracle JRE 8运行。

它可以正常使用本地IP地址绑定。

curl 127.0.0.1:9200

{
  "name" : "Deadly Ernest",
  "cluster_name" : "elasticsearch",
  "version" : {
    "number" : "5.0.0-alpha4",
    "build_hash" : "3f5b994",
    "build_date" : "2016-06-27T16:23:46.861Z",
    "build_snapshot" : false,
    "lucene_version" : "6.1.0"
  },
  "tagline" : "You Know, for Search"
}

但是当我尝试绑定公共IP地址时，它失败了。

取消注释并修改/etc/elasticsearch/elasticsearch.yml

network.host: 139.129.221.xxx

当我尝试使用sudo -i service elasticsearch restart启动服务时似乎没问题* Starting Elasticsearch Server ...done.

日志显示服务器无法正常启动。

Answer 1

经过多次尝试，我终于通过以下配置做到了。

/etc/elasticsearch/jvm.options

-Xms2g
-Xmx2g

/etc/elasticsearch/elasticsearch.yml

network.host: 139.129.221.xxx
http.port: 9200
discovery.zen.minimum_master_nodes: 1

然后运行sudo service elasticsearch restart以启动elasticsearch。
