Elasticsearch 错误 : BindTransportException[Failed to bind to [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

当我启动 elasticsearch 时，出现以下错误:

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。我是否应该更改任何其他设置以使其正常工作。感谢任何帮助

您是否有可能尝试绑定(bind)到 IP 地址以通过 network.host 或 bind.host 参数进行监听，但此参数不存在系统？

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