Elasticsearch 错误 – 未配置初始节点名

下载 elasticsearch 并解压后，未做任何配置，报错如下：

[2019-10-31T15:26:19,120][INFO ][o.e.b.BootstrapChecks    ] [node-1] bound or publishing to a non-loopback address, enforcing bootstrap checks 
 ERROR: [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

解决：

# 删除配置文件[config/elasticsearch.yml]中的注释
node.name: node-1
# 删除配置文件[config/elasticsearch.yml]中的的注释
cluster.initial_master_nodes: ["node-1"]
