Question

我在CentOS服务器上安装了elasticsearch最新版本5.5。为了更改IP地址，我在elasticsearch.yml文件中添加了以下行：

network.host = xyz.xyz.xy.xy (My Centos IP address)
http.port: 9200

当我开始我的弹性搜索时，我收到以下错误：

我可以在不编辑elasticsearch.yml的情况下启动elasticsearch。但是我必须在我的centos机器之外访问elasticsearch。是否有任何其他设置我应该更改以使其工作。任何帮助表示赞赏

Answer 1

您是否有可能尝试绑定到IP地址以通过此系统上不存在的network.host或bind.host参数进行监听？

您可以分享ip addr list和elasticsearch.yml文件的输出（您可以使用grep "^[^#]" elasticsearch.yml来忽略评论。

Answer 2

我有同样的错误。跟随Unable to bind elasticsearch transport service to external interface之后消失了。

较新的Elasticsearch版本区分了开发模式和生产模式。如果您定义了任何非环回IP（即很可能不是127.0.0.1的任何其他IP），将进行一些测试。从日志中：

...绑定或发布到非环回地址，强制执行引导检查 ...节点验证异常 [1]引导检查失败 [1]：默认发现设置不适合生产使用；必须至少配置[discovery.seed_hosts，discovery.seed_providers，cluster.initial_master_nodes]之一

因此，如果您需要非回送IP，例如在elasticsearch.yml中定义：

<?php define ('HOST','localhost'); define ('USER','root'); define ('PASS',''); define ('DB','tut'); ?>

然后重新启动。
