弹性搜索错误:绑定传输异常[无法绑定到 [9300-9400]

Question

我已经在我的 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：

我可以在不编辑我的 elasticsearch.yml 的情况下启动 elasticsearch。但是我必须在 centos 机器之外访问 elasticsearch。我是否应该更改任何其他设置以使其正常工作。任何帮助不胜感激

Answer 1

您是否可能尝试绑定到IP地址以通过network.host或bind.host参数进行侦听，而此系统上不存在该地址？

你能分享ip addr list和你的 elasticsearch.yml 文件的输出吗(你可以使用grep "^[^#]" elasticsearch.yml来忽略评论。

Answer 2

我遇到了同样的错误。在遵循无法将 elasticsearch 传输服务绑定到外部接口后，它消失了。

较新的 elasticsearch 版本区分开发模式和生产模式。如果您定义任何非环回 IP(即很可能是 127.0.0.1 以外的任何内容(，则会有一些测试。从日志中：

。绑定或发布到非环回地址，强制引导程序检查 ...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] 中的一个

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

node.name: $myNodeName cluster.initial_master_nodes : $myNodeName

，然后再次重新启动。
