Elasticsearch错误：BindTransportException [无法绑定到[9300-9400]

Question

我在我的CentOS服务器上安装了elasticsearch最新版本5.5。为了改变IP地址，我已经添加了以下行elasticsearch.yml文件：

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

当我开始我的elasticsearch，我收到以下错误：

我能开始elasticsearch而不编辑我的elasticsearch.yml。但我必须在我的centos机器之外访问elasticsearch。有没有其他的设置需要改变才能使其工作。任何帮助表示赞赏

是否有可能是你试图绑定到一个IP地址通过参数network.host或bind.host监听，这在系统上不存在？

你能分享的ip addr list输出和你elasticsearch.yml文件（你可以使用grep "^[^#]" elasticsearch.yml忽略的意见。
