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} }
     ],

       },

       "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": {

       "concurrent_requests": ${es.bulk.concurrent.requests},

     }
   }
 }'
