Elasticsearch错误“引导检查失败"；(绑定非环回地址) [英] Elasticsearch Error "bootstrap checks failed" (Binding non-loopback address)

问题描述

最近，在安装Elasticsearch 7.3.2之后，我发现绑定到localhost或127.0.0.1的服务器可以正常工作.

Recently, after installation of Elasticsearch 7.3.2, I found out that the server is working fine when bound to the localhost or 127.0.0.1.

但是我将其提供给外部使用，即在特定IP或0.0.0.0上，它引发了我的错误并停止了服务器:

But I made it available for external use, that is on particular IP or 0.0.0.0, it raised me error and stopped the server:

绑定或发布到非环回地址，强制执行引导检查[2019-09-19T18:21:43,962] [错误] [o.e.b.Bootstrap] [MARFEEN]节点验证异常[1]引导检查失败

bound or publishing to a non-loopback address, enforcing bootstrap checks [2019-09-19T18:21:43,962][ERROR][o.e.b.Bootstrap ] [MARFEEN] node validation exception [1] bootstrap checks failed

推荐答案

此解决方案无法获得任何答案，其中大多数与最大打开文件限制有关.但是，当我在elasticsearch.yml文件中启用配置属性 discovery.seed_hosts 时，此问题就解决了:

Could not get any answer on this solution, most of them were related to max opened file limits. But it was solved when I enabled a config property discovery.seed_hosts in elasticsearch.yml file:

# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
network.host: 0.0.0.0
#
# Set a custom port for HTTP:
#
#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"]

启用上述属性后，它在非环回主机上也可以正常工作.

After enabling the above property, it worked fine on non-loopback host also.
