ElasticSearch是一个基于Lucene构建的开源，分布式，RESTful搜索引擎。设计用于云计算中，能够达到实时搜索，稳定，可靠，快速，安装使用方便，下面将讲解一下ElasticSearch简单安装。
1、Linux中下载：
wget https://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-1.4.2.tar.gz
2、解压下载包执行 tar -xzvf elasticsearch-1.4.2.tar.gz 命令如下：
[root@yoodb tmp]# tar -xzvf elasticsearch-1.4.2.tar.gz elasticsearch-1.4.2/config/elasticsearch.yml elasticsearch-1.4.2/config/logging.yml elasticsearch-1.4.2/bin/elasticsearch.bat elasticsearch-1.4.2/bin/plugin.bat elasticsearch-1.4.2/bin/service.bat elasticsearch-1.4.2/bin/elasticsearch.in.bat elasticsearch-1.4.2/bin/elasticsearch-service-mgr.exe elasticsearch-1.4.2/bin/elasticsearch-service-x64.exe elasticsearch-1.4.2/bin/elasticsearch-service-x86.exe elasticsearch-1.4.2/bin/plugin elasticsearch-1.4.2/bin/elasticsearch elasticsearch-1.4.2/bin/elasticsearch.in.sh elasticsearch-1.4.2/lib/sigar/libsigar-amd64-freebsd-6.so elasticsearch-1.4.2/lib/sigar/libsigar-amd64-linux.so elasticsearch-1.4.2/lib/sigar/libsigar-amd64-solaris.so elasticsearch-1.4.2/lib/sigar/libsigar-ia64-linux.so elasticsearch-1.4.2/lib/sigar/libsigar-sparc-solaris.so elasticsearch-1.4.2/lib/sigar/libsigar-sparc64-solaris.so elasticsearch-1.4.2/lib/sigar/libsigar-universal-macosx.dylib elasticsearch-1.4.2/lib/sigar/libsigar-universal64-macosx.dylib elasticsearch-1.4.2/lib/sigar/libsigar-x86-freebsd-5.so elasticsearch-1.4.2/lib/sigar/libsigar-x86-freebsd-6.so elasticsearch-1.4.2/lib/sigar/libsigar-x86-linux.so elasticsearch-1.4.2/lib/sigar/libsigar-x86-solaris.so elasticsearch-1.4.2/lib/sigar/sigar-1.6.4.jar elasticsearch-1.4.2/lib/sigar/sigar-amd64-winnt.dll elasticsearch-1.4.2/lib/sigar/sigar-x86-winnt.dll elasticsearch-1.4.2/lib/sigar/sigar-x86-winnt.lib elasticsearch-1.4.2/README.textile elasticsearch-1.4.2/LICENSE.txt elasticsearch-1.4.2/NOTICE.txt elasticsearch-1.4.2/lib/lucene-core-4.10.2.jar elasticsearch-1.4.2/lib/lucene-analyzers-common-4.10.2.jar elasticsearch-1.4.2/lib/lucene-queries-4.10.2.jar elasticsearch-1.4.2/lib/lucene-memory-4.10.2.jar elasticsearch-1.4.2/lib/lucene-highlighter-4.10.2.jar elasticsearch-1.4.2/lib/lucene-queryparser-4.10.2.jar elasticsearch-1.4.2/lib/lucene-sandbox-4.10.2.jar elasticsearch-1.4.2/lib/lucene-suggest-4.10.2.jar elasticsearch-1.4.2/lib/lucene-misc-4.10.2.jar elasticsearch-1.4.2/lib/lucene-join-4.10.2.jar elasticsearch-1.4.2/lib/lucene-grouping-4.10.2.jar elasticsearch-1.4.2/lib/lucene-spatial-4.10.2.jar elasticsearch-1.4.2/lib/spatial4j-0.4.1.jar elasticsearch-1.4.2/lib/lucene-expressions-4.10.2.jar elasticsearch-1.4.2/lib/antlr-runtime-3.5.jar elasticsearch-1.4.2/lib/asm-4.1.jar elasticsearch-1.4.2/lib/asm-commons-4.1.jar elasticsearch-1.4.2/lib/jts-1.13.jar elasticsearch-1.4.2/lib/groovy-all-2.3.2.jar elasticsearch-1.4.2/lib/log4j-1.2.17.jar elasticsearch-1.4.2/lib/jna-4.1.0.jar elasticsearch-1.4.2/lib/elasticsearch-1.4.2.jar
3、进入解压后的elasticsearch-1.4.2目录中，执行 ./bin/elasticsearch 单机运行，如下：
[root@localhost elasticsearch-1.4.2]# ./bin/elasticsearch

}
此时说明已经启动。
5、按ctrl+c退出服务并停止，显示如下：
