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/1

body:
{
  "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/1

respond:
{
    "_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
