Elasticsearch远程调用配置

操作过程：

vim config/elasticsearch.yml，在文件的最后加上 

network.host: 0.0.0.0 #注意“:”后要有空格和语句前面有空格

错误提示：

解决：

增加：transport.host: localhost

transport.tcp.port: 9300

http.port: 9200

总结：

应该是新版本的更改，完整的语句是增加 

transport.host: localhost

transport.tcp.port: 9300

http.port: 9200

network.host: 0.0.0.0
