一行学学 ElasticSearch(1)

最近产品需要用到ElasticSearch,因此开始学习一下，有兴趣的可以一起。

好，今天从安装开始吧！

网上说 ElasticSearch 是开箱即用，解压即可使用。试试吧！

首先，当然是下载，地址如下：http://www.elasticsearch.org/download/

好吧，得到了elasticsearch-1.0.0.tar.gz OK （最新版本1.0）。

[root@localhost Downloads]# ls
elasticsearch-1.0.0.tar.gz

//解压：

[root@localhost Downloads]# tar -zxvf elasticsearch-1.0.0.tar.gz

//移动到运行目录

[root@localhost Downloads]# mv elasticsearch-1.0.0 /usr/local/elasticsearch-1.0.0

现在应该可以启动了吧

[root@localhost Downloads]# cd /usr/local/elasticsearch-1.0.0/bin
[root@localhost bin]# ./elasticsearch

OK

访问一下试试：

打开浏览器,输入http://192.168.25.129:9200/

{
  "status" : 200,
  "name" : "Shatterstar",
  "version" : {
    "number" : "1.0.0",
    "build_hash" : "a46900e9c72c0a623d71b54016357d5f94c8ea32",
    "build_timestamp" : "2014-02-12T16:18:34Z",
    "build_snapshot" : false,
    "lucene_version" : "4.6"
  },
  "tagline" : "You Know, for Search"
}

大功告成！

注意：jdk1.6以上版本哦！
