Elasticsearch版本5.1参考来源：https://github.com/medcl/elasticsearch-analysis-ik一、首先确保jdk版本在1.8以上# java -versionjava version "1.8.0_112"Java(TM) SE Runtime Environment (build 1.8.0_112-b15)

批量（_bulk）操作：一个好的批次最好保持在5~15MB

版本：ElasticSearch 5.2.0        在Eclipse下直接创建Java Project，并引入ES目录下的lib包这种是行不通的，会找不到PreBuiltTransportClient类。        正确的做法是使用Maven生成项目（Maven是什么？请自行百度脑补，我也是刚脑补完成，之前没用过，请原谅我的Low B！新版本的Eclipse是自带了Mave

参考自《Elasticsearch Definitive Guide》        Elasticsearch默认堆内存为1 GB，对于实际应用，显然不够，不建议使用默认配置。        设置Elasticsearch的内存又两种方案，最简单的方法是设置一个环境变量为ES_HEAP_SIZE。当服务器启动时，它将读取此环境变量并相应设置内存。命令如下：export ES_HEAP

网上关于elasticsearch的教程已经很多了，本人主要是将安装过程中的一些步骤或遇到的问题备注留作以后使用，有兴趣的看客欢迎交流。安装运行1、前置安装java8jdk-8u112-linux-x64.rpm下载地址：http://www.oracle.com/technetwork/java/javase/downloads/index.html2、下载w
