Crowiで検索を有効化する(CentOS 6.8)

Last updated at Posted at 2016-10-31

Crowiで検索を有効化する

Crowiシリーズの3本目である。

  1. Crowiをセットアップする(CentOS 6.8)
  2. CrowiでGoogleAppsでのログインを有効化する

version1.5.0から実装された検索機能を使用する。

環境

  • CentOS 6.8
  • Java 1.7 (1.6で動かそうとして失敗した)
  • Crowi v1.5.0

Elasticsearchを導入する

検索機能を使用するにはElasticserachが必要だそうなのでこれを導入する。

レポジトリの設定

  1. yumレポジトリの設定
    $ rpm --import https://packages.elastic.co/GPG-KEY-elasticsearch

  2. レポジトリの設定を書き換える

/etc/yum.repos.d/elasticsearch.repo
[elasticsearch-2.x]
name=Elasticsearch repository for 2.x packages
baseurl=http://packages.elastic.co/elasticsearch/2.x/centos
gpgcheck=1
gpgkey=http://packages.elastic.co/GPG-KEY-elasticsearch
enabled=1
  • イントール
    $ yum install elasticsearch

  • 日本語対応するためにanalysis-kuromojiをいれる ここでつまる

$ cd /usr/share/elasticsearch
$ bin/plugin install analysis-kuromoji
  • javaが1.7以上じゃないと動かないらしい
    $ yum install java-1.7.0-openjdk

  • もっかいkuromojiをいれる
    $ bin/plugin install analysis-kuromoji

  • Elasticsearchを再起動
    $ /etc/init.d/elasticsearch start

  • 自動起動を設定する
    $ chkconfig --add elasticsearch

  • 設定を変更する
    /etc/elasticsearch/elasticsearch.ymlを書き換える

/etc/elasticsearch/elasticsearch.yml
 # network.host: 192.168.0.1
network.host: YOURIP
  • 書き換えたらリスタートを忘れずに
    $ /etc/init.d/elasticsearch restart

  • Elasticsearchとkuromojiの動作確認をする

  • crowi側で読ませる
/etc/sysconfig/crowi
ELASTICSEARCH_URI=http://YOURIP:9200

Crowi側の設定

秒でおわる

  1. forever start app.js
  2. CrowiのGUIから"管理" -> "検索管理" -> "Build Now"

完成
