ElasticSearch7 设置外网访问失败

elasticsearch外网访问9200端口失败，bootstrap checks failed,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

Linux安装ElasticSearch，修改配置文件elasticsearch.yml 后启动失败。

  • CentOS Linux release 7.5
  • ElasticSearch version 7.3.0
  • Java openjdk version 1.8.0_222

我的设置：

vim /etc/elasticsearch/elasticsearch.yml
# ---------------------------------- Network -----------------------------------## Set the bind address to a specific IP (IPv4 or IPv6):#network.host: 0.0.0.0#

查看日志发现 （npm 安装elasticsearch 日志路径 /var/log/elasticsearch）

[ERROR][o.e.b.Bootstrap] [localhost.localdomain] 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

翻译过来就是，在discovery.seed_hosts,discovery.seed_providers, cluster.initial_master_nodes中至少设置一项。

仔细看了官网文档：discovery.seed_hosts 设置成默认值即可。

discovery.seed_hosts: ["127.0.0.1", "[::1]"]
