ES-ElasticSearch端口和安装问题

. elasticsearch安装

官方下载地址：https://www.elastic.co/downloads/elasticsearch

修改配置文件

catconfig/elasticsearch.yml |grep-v"#"
cluster.name: rainbow
network.host: 127.0.0.1
http.port: 9200

cluster.name表示es集群的名称，可以自定义一个自己需要的集群名称
http.port 表示对外提供http服务时的http端口。
network.host 表示本地监听绑定的ip地址，此处为测试环境，直接使用本机的ip地址 127.0.0.1.

1	`nohup./bin/elasticsearch&`

es启动监听两个端口，9300和9200
9300端口是使用tcp客户端连接使用的端口；
9200端口是通过http协议连接es使用的端口；

2. 使用http方式增加和查询数据

增加数据（http PUT）：

/user_idx/type_tags/12'{"name" : "Mr.YF", "tags" : ["Go","Java","Lua","C++","Tcl","..."]}'
{"_index":"user_idx","_type":"type_tags","_id":"12","_version":1,"_shards":{"total":2,"successful":1,"failed":0},"created":true}

3. 使用elasticsearch客户端编写java代码访问es

编写es客户端提供者类，对es连接做简单的封装

SearchClientProvider.java

packageorg.wyf.elasticsearch.search;
/**

privatestaticfinalLogger LOGGER = LoggerFactory.getLogger(SearchClientProvider.class);

publicTransportClient get() {
returnthis.client;
}
@PreDestroy
publicsynchronizedvoidclose() {
if(thisnull) {
this.client.close();
}
}
@PostConstruct
publicsynchronizedvoidinit() {
if(!inited) {
try{
Map<String, String> config = XmlProperties.loadFromXml("properties/elasticsearch.xml");
ifnull) {
out.println("load xml err");
return;
}
Iterator<Map.Entry<String, String>> iterator = config.entrySet().iterator();
newHashMap<String, String>();
while(iterator.hasNext()) {
Map.Entry<String, String> next = iterator.next();
if(!next.getKey().equals("transport.addresses")) {
settingConfig.put(next.getKey(), next.getValue());
}
}
Settings settings = Settings.builder().put(settingConfig).build();
TransportClient client = TransportClient.builder().settings(settings).build();
this.client = client;
String[] addresses = config.get("transport.addresses"
