elasticsearch 安装记录
windows下的安装即开箱即用，到bin目录下打开elasticsearch.bat，访问localhost:9200，页面显示：
{ "name" : "Windshear", "cluster_name" : "elasticsearch", "version" : { "number" : "2.3.5", "build_hash" : "90f439ff60a3c0f497f91663701e64ccd01edbb4", "build_timestamp" : "2016-07-27T10:36:52Z", "build_snapshot" : false, "lucene_version" : "5.5.0" }, "tagline" : "You Know, for Search"}
发送post请求，将需要添加的信息放到body中：
http://localhost:9200/myindex/share/1body:{ "url": "www.baidu.com", "place": "Beijing", "company": "Baidu"}
而后用get请求获取到该消息：
http://localhost:9200/myindex/share/1respond:{ "_index": "myindex", "_type": "share", "_id": "1", "_version": 4, "found": true, "_source": { "url": "www.baidu.com", "place": "Beijing", "company": "Baidu" }}
============================>
linux环境下的安装遇到了几个问题：
首先解压文件：
tar -zxvf elasticsearch-2.3.5.tar.gz
进入目录elasticsearch-2.3.5：
./bin/elasticsearch
但是会报错：
Exception in thread "main" java.lang.RuntimeException: don‘t run elasticsearch as root. at org.elasticsearch.bootstrap.Bootstrap.initializeNatives(Bootstrap.java:93) at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:144) at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:270) at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:35)Refer to the log for complete error details.
于是，将解压的整个目录更换用户组与用户：
chown -R ccj:ccj elasticsearch-2.3.5
然后切换到该用户：
su - ccj
再开启elasticsearch
