Elasticsearch 与 Mongodb 数据同步问题

1、mongo-connector工具

首先安装python环境

wget http://www.python.org/ftp/python/3.0.1/Python-3.0.1.tgz

tar -zxvf Python-3.0.1.tgz

cd Python-3.0.1

./configure

make all

make install

看来新装的版本生效了，做个软连接应该就OK。

ln -s /usr/local/bin/python3.0 /usr/bin/python

python -V

安装pip

$ wget https://bootstrap.pypa.io/get-pip.py

$ python get-pip.py

$ pip -V　　#查看pip版本

安装mongo-connector 

如果是 Elasticsearch 5.x

 pip install 'mongo-connector[elastic5]'

[Reference] https://github.com/mongodb-labs/mongo-connector

执行命令：

 mongo-connector -m 192.9.8.204:27017 -t 192.9.8.223:9200 -d elastic2_doc_manager -n wymlib.ym_literature

-m :mongodb地址，-t：目的地址，-d : Used to specify the path to each doc manager file that will be used.    -n:指定数据库

2、elasticsearch-river-mongodb

该工具只支持 elasticsearch 1.7.3 及以下版本

bin/plugin --install com.github.richardwilly98.elasticsearch/elasticsearch-river-mongodb/2.0.9

mongodb-river同步信息属性配置完整版：

$ curl -XPUT "localhost:9200/_river/${es.river.name}/_meta" -d '
{
  "type": "mongodb",
  "mongodb": { 
    "servers":
    [
      { "host": ${mongo.instance1.host}, "port": ${mongo.instance1.port} },
      { "host": ${mongo.instance2.host}, "port": ${mongo.instance2.port} }
    ],

      },
      "skip_initial_import" : ${mongo.skip.initial.import},
      "store_statistics" : ${mongo.store.statistics},
    },
    "credentials":
    [
      { "db": "local", "user": ${mongo.local.user}, "password": ${mongo.local.password} },
      { "db": "admin", "user": ${mongo.db.user}, "password": ${mongo.db.password} }
    ],
    "db": ${mongo.db.name}, 
    "collection": ${mongo.collection.name}, 
    "gridfs": ${mongo.is.gridfs.collection},
    "filter": ${mongo.filter}
  }, 
  "index": { 
    "name": ${es.index.name}, 
    "throttle_size": ${es.throttle.size},
    "bulk_size": ${es.bulk.size},
    "type": ${es.type.name}
    "bulk": {
      "actions": ${es.bulk.actions},
      "size": ${es.bulk.size},
      "concurrent_requests": ${es.bulk.concurrent.requests},
      "flush_interval": ${es.bulk.flush.interval}
    }
  }
}'
