JDKとかは入ってる前提で

tarを入手

今回は1.5.1

ここから

tarを展開

tar -xzf ~/Downloads/elasticsearch-1.5.1.tar.gz

確認

help

% ./elasticsearch-1.5.1/bin/elasticsearch --help                                                                                                                  ~
Usage: ./elasticsearch-1.5.1/bin/elasticsearch [-vdh] [-p pidfile] [-D prop] [-X prop]
Start elasticsearch.
    -d            daemonize (run in background)
    -p pidfile    write PID to <pidfile>
    -h
    --help        print command line options
    -v            print elasticsearch version, then exit
    -D prop       set JAVA system property
    -X prop       set non-standard JAVA system property
   --prop=val
   --prop val     set elasticsearch property (i.e. -Des.<prop>=<val>)

必要があれば$PATHを通せばよい

起動

% ./elasticsearch-1.5.1/bin/elasticsearch

確認

% curl "http://localhost:9200"
{
  "status" : 200,
  "name" : "Northstar",
  "cluster_name" : "elasticsearch",
  "version" : {
    "number" : "1.5.1",
    "build_hash" : "5e38401bc4e4388537a615569ac60925788e1cf4",
    "build_timestamp" : "2015-04-09T13:41:35Z",
    "build_snapshot" : false,
    "lucene_version" : "4.10.4"
  },
  "tagline" : "You Know, for Search"
}

番外: Pluginのインストール

kuromoji入れる

% ./elasticsearch-1.5.1/bin/plugin --install elasticsearch/elasticsearch-analysis-kuromoji/2.5.0

1.5.1に2.5.0で大丈夫かと思いつつ。入れたら再起動。
