启用Crowi搜索功能

这是Crowi系列的第三部作品。

1. 在CentOS 6.8上安装设置Crowi

 

在Crowi上启用Google Apps登录

使用1.5.0版本新增的搜索功能。

环境

• CentOS 6.8

 

• Java 1.7 (1.6で動かそうとして失敗した)

 

Crowi v1.5.0

引入Elasticsearch

据说要使用搜索功能，就需要引入Elasticsearch。

仓库设置

1. 修改yum存储库设置

 

1. $ rpm –import https://packages.elastic.co/GPG-KEY-elasticsearch

 

更改存储库的设置

[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

 # 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

 

Elasticsearch

$ curl 'http://YOURIP:9200/'      
{
  "name" : "Gosamyr",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "RT6I6Z3JSliJ_UZdSkvcnQ",
  "version" : {
    "number" : "2.4.1",
    "build_hash" : "c67dc32e24162035d18d6fe1e952c4cbcbe79d16",
    "build_timestamp" : "2016-09-27T18:57:55Z",
    "build_snapshot" : false,
    "lucene_version" : "5.5.2"
  },
  "tagline" : "You Know, for Search"
}

「kuromoji」的中文翻译只需要一种选项。

 $ curl -X GET 'http://YOURIP:9200/_nodes/plugins?pretty'

    }
  }
}

crowi側で読ませる

ELASTICSEARCH_URI=http://YOURIP:9200

Crowi的配置在侧边。

1. 永远开始 app.js
2. 在 Crowi 的 GUI 中选择 “管理” -> “検索管理” -> “立即构建”

请参考

尝试使用yum在CentOS上安装Elasticsearch
尝试升级到Crowi v1.5.0
