java - elasticsearch java.library.pat 错误中没有 MeCab

Question

我无法在elasticsearch中使用mecab tokenizer安装elasticsearch 5.2和mecab-ko、mecab-ko-dict、analysis-mecab-ko(elasticsearch mecab插件)后，我可以像这样创建索引mecab tokenizer:

#!/usr/bin/env bash
ES='http://localhost:9200'
ESIDX='seunjeon-idx'

echo "put setting"
curl -XPUT "${ES}/${ESIDX}/?pretty" -d '{
  "settings" : {
    "index":{
      "analysis":{
        "analyzer":{
          "korean":{
            "type":"custom",
            "tokenizer":"seunjeon_default_tokenizer"
          }
        },
        "tokenizer": {
          "seunjeon_default_tokenizer": {
            "type": "mecab_ko_standard_tokenizer",
            "mecab_args": "/usr/local/lib/mecab/dic/mecab-ko-dic"
          }
        }
      }
    }
  }
}'

但是下面的curl命令不起作用。

curl -XGET "http://192.168.0.10:9200/seunjeon-idx/_analyze?
analyzer=korean&pretty" -d '삼성전자'

执行上述命令后，/var/log/elasticsearch/elasticsearch.log 中显示以下日志:

尝试并检查:

ldconfig -p | grep libmecab
libmecab.so.2 (libc6,x86-64) => /usr/local/lib/libmecab.so.2
libmecab.so (libc6,x86-64) => /usr/local/lib/libmecab.so

Answer 1

您可以尝试设置 -Djava.library.path=/usr/local/lib:/path/to/mecab.so/dir在弹性启动脚本中。
