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 '
